This meeting was audio and video recorded and can be accessed at the Deschutes County Meeting Portal webpage www.deschutes.org/meetings. CALL TO ORDER: Chair Adair called the meeting to order at 1:00 pm. CITIZEN INPUT: None ACTION ITEMS: 1. Presentations of progress and ARPA-related funding requests for Terrebonne Sanitary District and Tumalo Basin Sewer District Chris Doty, Road Director, introduced presentations by representatives from the Terrebonne Sanitary District and Tumalo Basin Sewer District who will provide updates on progress made to develop sewer systems for their respective communities. Tim Brown from the Terrebonne Sanitary District reported significant progress and said the district has received more requests for annexation into the system. Saying BOCC MEETING OCTOBER 28, 2024 PAGE 1 OF 7 the district is currently at a critical phase as it works on the system's final design, he shared the goal to take the project out to bid in conjunction with the City of Redmond's wastewater treatment facility expansion. He asked that the County allocate an additional $75,000 in ARPA funds to facilitate the completion of several key activities. Commissioner Adair said this request will be taken up by the Board in November in association with information from Finance regarding the return of some ARPA funds and new funding requests. She noted that the memo received from the Terrebonne Sanitary District identifies $35,000 as critical to this project. Responding to Commissioner Chang, Brown said the district would be interested to be loaned $75,000 if it cannot otherwise be allocated. Commissioner Chang said while the County wants to support the sanitary districts and their initiatives, it does not have $100,000 in ARPA funds that is not already committed. Ryan Rudnick from Parametrix said the Terrebonne district's ability to repay loans would be limited at the outset. Linda Swearingen added that both districts have applied for grant funding that could be used to puy back loaned funds. She spoke to aconcer ted effort by some e people to spread misinformation about the Terrebonne project and said the board for the Tumalo district will be sworn in in January. Commissioner DeBone suggested allocating $25,000 to $35,000 and extending the remainder as a loan to assist getting to the next step. In response to Commissioner DeBone, Doty said ODOT's US 97 / Lower Bridge Way project is proceeding and includes the installation of sewer lines. The County contributed $11 million to this project. Commissioner Adair asked about the contract with Murraysmith for the Tumalo wastewater feasibility study. Doty said although Murraysmith was bought out by another company, this contract was completed, and the information gleaned will be used to refine some of the presented concepts to determine if the system can be expanded. Responding to Commissioner DeBone, Rudnick said system development charges in Terrebonne may be $7500 and monthly rates approximately $85. Swearingen added that the more connections, the lower the monthly rates will be. BOCC MEETING OCTOBER 28, 2024 PAGE 2 OF 7 Robert Fish, representing the Tumalo Basin Sanitary District, reported a good amount of community support for this initiative and spoke to efforts to not alienate anyone as work proceeds. 2. Public Hearing regarding Energy Wise Services Protest of the Notice of Intent to Award a Contract for the Deschutes County Fair and Expo Center Solar PV System to E2 Solar LLC Lee Randall, Facilities Director, reminded that after the Board accepted staffs recommendation to utilize the design -build procurement method for the Solar PV System project, a qualifications -based Request For Proposals (RFP) was issued. Eric Nielsen, Capital Projects Manager, said the seven proposals received in response to the RFP were evaluated based on several criteria, including each responder's approach to provide the needed services and related project experience. E2 Solar received the highest score and was recommended for the contract award. After the Board approved the notice of intent to award the contract to E2 Solar, Energy Wise Services filed a protest. Stephanie Marshall, Senior Assistant Legal Counsel, explained the provisions in ORS 279B which outline the necessary legal criteria for considering a protest. Marshall li-.tPrl riPri-inn nnintc fnr the Rnarrl to rnncirlar in thic mattAr in accordance with ORS 279B, as follows: 1. Has the protestor demonstrated that all the higher ranked proposals are nonresponsive? 2. Has the protester demonstrated that the County failed to conduct the evaluation of proposals in accordance with the criteria or processes described in the solicitation materials? 3. Has the protestor demonstrated that the County abused its discretion in rejecting the protestor's proposal, or has the protestor demonstrated that the County's evaluation of proposals or the County's subsequent determination of award is otherwise in violation of ORS 279B or ORS 279A? Marshall concluded that State law grants discretion to the Board in evaluating proposals submitted in response to an RFP, and the Board based its evaluation of the proposals solely on their ranking, consistent with ORS 279B. The public hearing was opened at 1:36 pm. Peter Greenburg, representing Energy Wise Services, said the proposal submitted by E2 Solar includes a specific inverter which does not meet the requirements of BOCC MEETING OCTOBER 28, 2024 PAGE 3 OF 7 the project, and the proposed panels to be used are warranted by a company which is at risk of going out of business. Speaking to what he viewed as many unusual components in the RFP, Greenburg said the method used to score the proposals was not well -explained and it is not clear why a certain number of points were assigned to each proposal component. He disputed that the proposal from Energy Wise Services deserved to score as low as it did, shared specifics of the proposed materials, and said that the system proposed by Energy Wise is 20% larger than the next -largest system and would produce 356KW instead of 31OKW, which would result in a $350,000 difference in energy value produced over 20 years. Greenburg stressed the value of using the right materials and said the scoring of the proposals was subjective and did not consider the overall value of the project. Continuing, Greenburg questioned how a proposal for a fixed price contract could be scored based on a billing rate schedule and said the winning proposal shows a less than prevailing wage for the installers. Randall said in taking the design/build approach, the County was seeking proposals, not bids, and the RFP included information on how the proposals would be scored which is the standard approach for a qualifications -based selection. Randall explained why the substitution of materials and/or an alternate system u pprouch is nllnXA1nrl nnrl ci ihinrt to nnfnintinn NN— u1-- — — uJwb1. In response to discussion regarding wage rates, Wayne Powderly from the Cummings Group said only the field technicians are subject to prevailing wage rates. Randall believed the inclusion of an incorrect prevailing wage schedule to be a clerical error in the winning proposal. Nielsen confirmed that all of the involved parties understand that prevailing wage rates will be applied to the project. Commissioner Adair asked if other proposers besides E2 Solar indicated the use of the same Swiss product from a company that may go out of business. Randall said any issues of concern regarding materials or other items would be addressed and vetted in the design process —this would include determining and vetting each component and part of the design. Nielson said although Energy Wise did not include Exhibit C in its proposal, its proposal was only deemed incomplete instead of non -responsive. Because the scores had already been tallied, the failure of Energy Wise to not include this exhibit did not affect how Energy Wise scored. Commissioner Chang asked if the County's solicitation was sufficiently specific. Randall noted that proposers were given a two -week period to ask questions. BOCC MEETING OCTOBER 28, 2024 PAGE 4 OF 7 Greenburg said the RFP did not appear to be a true proposal for design services because responders proposed specific components that would be installed. Commissioner Chang agreed that while the RFP did not ask for a design, every response provided one. The public hearing was closed at 2:24 pm. CHANG: Move to close the oral and written records and proceed with conducting deliberations on this matter DEBONE: Second VOTE: CHANG: Yes DEBONE: Yes ADAIR: Chair votes yes. Motion Carried Commissioner DeBone stated his support of the RFP as issued and to deny the protest. He appreciated that this project will offset energy use and therefore be good for the environment. Commissioner Chang agreed that the solicitation was not unnecessarily restrictive or flawed Commissioner Adair asked if the project was limited to two buildings due to the amount of funds available. She stated her preference to purchase American -made products, wanted the County to be transparent, and noted that Energy Wise Services has been in the business for 14 years. Commissioner Chang reminded that E2 Solar can modify the conceptual design it proposed. He appreciated the explanation of the advantages of the alternate approach by Energy Wise. DEBONE: Move to uphold Document No. 2024-811 which declared the Notice of Intent to Award a contract for the Deschutes County Fair and Expo Center Solar PV System to E2 Solar, and deny the protest submitted from Energy Wise Services CHANG: Second VOTE: CHANG: Yes DEBONE: Yes ADAIR: Chair votes yes. Motion Carried BOCC MEETING OCTOBER 28, 2024 PAGE 5 OF 7 3. Consideration of Letter of Support for City of Redmond Wetlands Complex Road Director Chris Doty reported that the Bureau of Land Management (BLM) is soliciting comments on the City of Redmond's proposal to acquire 541.5 acres to accommodate expanding the City's wastewater treatment facility and associated wetland treatment complex. Doty presented a draft letter from the Board supporting this project. In response to Commissioner Adair, Doty said the project is expected to be completed in 2027. DEBONE: Move to approve a letter to the ELM supporting the City of Redmond's Wetlands Complex project CHANG: Second VOTE: CHANG: Yes DEBONE: Yes ADAIR: Chair votes yes. Motion Carried OTHER ITEMS: Commissioner DeBone referenced a letter from the Department of State Lands regarding ig �SLJ Niauncauvi i oil new maps UCIII ICdU1-1 g Jdge gl ollsC 1 IdlJlldl, Saying i ie will forward the letter to Peter Gutowsky, director of Community Development. Commissioner Chang was interested to know how much the map has changed and wanted to see both layers on one map. Commissioner DeBone referred to an email from Redmond regarding the large lot technical advisory committee. Commissioner Adair indicated she will attend this meeting. Commissioner Chang attended the Bend -Redmond Habitat for Humanity ribbon - cutting for seven townhouses on Cedar Avenue. Commissioner Adair reported on the Local Government Advisory Committee for Health & Human Services meeting in Salem last Friday, which featured an excellent report on homeless outreach in Eugene. Sharing that she was surprised to hear OHA Deputy Director of Behavioral Health Jon Collins say that building beds is not always the solution, she said more beds are needed in Central Oregon, including for youth. She hoped that in the future, more State representatives to this committee will attend in person rather than remotely.

Executive Session under ORS 192.660 (2) (e) Real Property Negotiations ADJOURN October 28, 2024 BOARD OF COUNTY COMMISSIONERS MEETING Page 2 of 2 1�3T ES COG2-A o MEETING DATE: October 28, 2024 SUBJECT: Presentations of progress and ARPA related funding requests for Terrebonne Sanitary District and Tumalo Basin Sewer District RECOMMENDED MOTION: Per Board direction BACKGROUND AND POLICY IMPLICATIONS: Representatives from the Terrebonne Sanitary District and Tumalo Basin Sewer District will individually present updates regarding progress and next steps in their respective efforts to develop sewer systems withing their communities. Each District will also present opportunities for additional investment by Deschutes County for the Board's consideration. Attached are summary documents from each District which outline their individual progress and articulate their individual funding request: Terrebonne for $75,000 and Tumalo for $25,000. BUDGET IMPACTS: In Terrebonne, funding contributions to date total: 1. $100,000: Feasibility Study (non-ARPA, partial grant funding, Parametrix) 2. $490,000: System refinement and design, community outreach, and district formation expense (100% ARPA, Parametrix) 3. $1,000,000: Treatment capacity in City of Redmond Wetlands Complex (50% ARPA and 50% Road Department PILT) 4. $1,493,000: Contribution to ODOT US 97 Project to install pressure sewer line in reconstructed county roads and state highway crossings ($1,000,000 via Senator Bonham's CSFRF allocation, $493,000 Road Department PILT) in Tumalo, funding contributions to date total: 1. $149,000 Feasibility Study (100% ARPA, Murraysmith contract) 2. $75,000: Planning, administrative, and public outreach expenses associated with District formation (100% ARPA, Parametrix/Blankenship/Swearingen) ATTENDANCE: Chris Doty, Road Department Director Tim Brown, Terrebonne Sanitary District Rob Fish, Tumalo Basin Sewer District Ryan Rudnick, PE, Parametrix Inc (consultant to both projects PO Box 2171 Terrebonne, Oregon 97760 TERREBONNEwww.terrebonnesd.org S A N I T A R Y D I S T R I C T terrebonnesanitary@amail.com %IT (425) 224-2458 Terrebonne Sanitary District Update & Funding Request District Update: The Terrebonne Sanitary District has made significant progress in 2024 thanks to past ARPA allocations by the BOCC. Nearly 100 annexation applications were received from property owners in Terrebonne, signaling growing community interest and support for the system. The Terrebonne STEP Collection System Project is on the DEQ CWSRF funding Intended Use Plan, including $2 million in principal forgiveness. Additionally, $1 million in Community Project Grant Funding for the Terrebonne Sewer system is included in HR 8998, thanks to Representative Lori Chavez-DeRemer. ODOT has awarded the US 97 / Lower Bridge Way project to High Desert Aggregate & Paving, who has begun installing sewer mains within the highway project limits. The District is currently working on finalizing the sewer system design and securing funding to construct the system over the next several years. The Terrebonne Sewer Planning & Design project is nearing a critical phase in where additional funding is essential to ensure its successful completion in 2024 with "shovel -ready" status. To cover unanticipated efforts and wrap up the project effectively, we are requesting an additional $75,000 in ARPA funding. Unanticipated efforts: The Terrebonne Sewer Planning & Design project faced several unanticipated efforts, including additional work for the annexation process, cultural/historical surveys, and biological evaluations, as well as legal and regulatory agency coordination. These unforeseen activities have contributed to the need for additional funding to ensure the project's successful completion. Opportunity for Successful Completion: Securing this additional funding will enable us to complete several key activities that are crucial for the project's success. These include finalizing the Planning Loan Application and checklist requirements, completing the CWSRF design/construction loan application, and wrapping up the annexation nrnrPcc Arlriitinnal1v MIP Will hP ahIP to PnrlanP sllbconsultant servlrPS from Nanry RIanICPnghin for administrative counsel and support, and Linda Swearingen for public outreach/involvement. Continued meetings, project management, finalizing plans and specs for DEQ review and approval, and preparing bid documents for contractor bidding are also part of this request. Funding Request: We are requesting an additional $75,000 to cover these critical activities and ensure the project's successful completion. If $75,000 is not available, a minimum of $35,000 is requested to assist the District with securing the CWSRF funding it needs to cover its administrative expenses and continue sewer planning and design efforts next year. This reduced budget would cover the services described above, except for final plans/specs and bid documents which would be deferred until future funding is available via other sources. Project Benefits: The additional funding will help reduce the risk of exposure to wastewater effluent, preserving public and environmental health. It will also help preserve low-income housing at risk of septic system failure, which could lead to houselessness, and facilitate the development of workforce and affordable housing. Additionally, it is expected to eventually reduce the burden on Environmental Health Division staff resources related to dealing with onsite wastewater system issues in Terrebonne. Conclusion: The additional funding will support the successful completion of the Terrebonne Sewer Planning & Design project. This investment will help finalize the project and secure necessary funding for future efforts. Thank you for considering this request. Tim Brown Terrebonne Sanitary District Board President Subiect: Tumalo Basin Sanitary District (TBSD) Updates and Additional Funding Request District Updates: The Tumalo Basin Sewer District (TBSD) has been legally formed with strong community support and predominantly positive feedback. We are pleased to report that five volunteers are running for the five District board positions in the current November election. Draft ordinances have been prepared for the Board to approve in early 2025, and initial coordination with funding agencies such as the Infrastructure Finance Authority (IFA), Department of Environmental Quality (DEQ), and USDA Rural Development (USDA-RD) has begun to secure funding for future phases of work. The TBSD is seeking to begin exploring alternatives for effluent treatment and disposal, with the goal of preparing a Preliminary Engineering Report (PER) next year. This report will be crucial for securing future project funding and ensuring the sustainability of our community's future sewer system. The TBSD also will need administrative support and materials to facilitate effective operations, after board members are sworn into their positions in early 2025. Additional Funding Request: While the initial $75,000 ARPA funding has instrumental in the TBSDs success thus far, several opportunities have been identified to maintain momentum and prepare the District for comprehensive sewer planning next year. An additional $25,000 would provide for the following: 1. Conduct Initial Evaluations on Effluent Treatment and Disposal Options: $17,500 • Alternatives to be Explored: Wastewater Lagoons, Textile Filters (Orenco AX), Membrane Bioreactors (MBR) • Deliverables: Existing Conditions Base Map for layout and illustration of system alternatives, calculations for land requirements, memo on effluent disposal/reuse options, and conceptual figures 2. Acquire Essential District Materials: $500 • Projector & Screen: $400 • Mouse for the district laptop: $30 • Miscellaneous/Contingency: $70 3. Secure Professional Services: $5,000 • Retainer for Bookkeeper: $2,500 • Retainer for Lawyer: $2,500 4. Prepare Funding Applications: $2,000 • DEQ CWSRF Planning Grant: $1,000 • Business Oregon Water/Wastewater Technical Assistance Grant: $1,000 Total Additional Funding Requested: $25,000 Immediate Needs and Benefits: • Identify System Alternatives: This research will lay the groundwork for sewer system options that can be further studied and refined in the coming year, providing a clear path forward for our community's wastewater management. • Community Engagement: The materials and professional services funded by this request will support ongoing community conversations and engagement, fostering transparency and trust. • Strategic Planning: Early evaluations and preparations will provide a solid foundation for the Preliminary Engineering Report, making our future funding applications more robust and compelling. Conclusion: We believe that this additional funding will support TBSD and the continuation of efforts towards District setup and sewer planning. The proposed budget will enable us to gather critical information, support community discussions, and prepare for future funding applications. We appreciate your consideration and support in this matter. Thank you for your time, attention, and support thus far. Az� F-;;31� Rob Fish, Tumalo Basin Sanitary District 1�vTES CO C, G BOARD OF COMMISSIONERS MEETING DATE: October 28, 2024 SUBIECT: Public Hearing regarding Energy Wise Services Protest of Document No. 2024-811 Notice of Intent to Award a Contract for the Deschutes County Fair and Expo Center Solar PV System to E2 Solar LLC. BACKGROUND: Oregon Revised Statute (ORS 279C.527-528) requires that public entities spend 1.5% of the total contract price of a public improvement contract for new construction projects $5 million or greater on green energy technology or an alternative, regardless of funding source. Green energy technology includes solar technology such as photovoltaic systems. A photovoltaic (PV) solar technology system is proposed as part of the Courthouse Expansion project to comply with the 1.5% green energy technology requirement. Due to limitations of the Courthouse site and roof area the system is proposed to be constructed at the Deschutes County Fair and Expo Center. On July 24, 2024 staff presented the Design -Build Findings of Fact and the Board approved Order No. 2024-028 exempting the Solar PV System project from competitive bidding and authorizing the use of design -build services of contracting for the Solar PV System. On August 7, 2024 the Facilities Department issued a publicly advertised RFP for a Design - Build Contractor for the Solar PV Project in accordance with ORS 279C.400 - 279C.410. A copy of the RFP is attached hereto. The Facilities Department received seven (7) formal proposals by the 2:00pm deadline on September 11, 2024 and the proposals were reviewed by a scoring committee made up four (4) representatives from the Fair and Expo Center and the Facilities Department. Proposals were evaluated based on the following categories and ranked by their total score out of 100 points possible: • Cover Letter (Pass/Fail) • Proposed Responder's Project Team (20 points max.) • Responder's Approach to Provide Solar and PV Related Services (20 points max.) • Responder's Customer Service (20 points max.) • Responder's Related Project Experience (20 points max.) • Responder's References (10 points max.) • Responder's Billing Rates/Fee Schedule (15 points max.) • Exhibit C: Signature Sheet (Pass/Fail) E2 Solar received the highest scoring by the committee during the evaluation process and is being recommended for award of the contract. A copy of the scoring summary for the selection process is attached. On October 2, 2024 the Board considered the recommendation of the scoring committee at a regularly scheduled meeting. The Board voted 3-0 to approve Document No. 2024-811. Thereafter, on October 4, 2024, Deschutes County received a formal protest from Energy Wise Services of the Notice of Intent to Award, Document No. 2024-811. A copy of the protest letter is attached hereto. In accordance with ORS 27913.405 and .410, the Energy Wise Systems protest is before the Board for consideration. LEGAL CRITERIA: 1. ORS 27913.405 ORS 279B.405(4) states that the contracting agency (the Board) shall consider a protest if it is timely filed and contains the following: (a) Sufficient information to identify the solicitation that is the subject of the protest; (b) The grounds that demonstrate how the procurement process is contrary to law or how the solicitation document is unnecessarily restrictive, is legally flawed or improperly iy SpeCiiieS a brand iu name; (c) Evidence or supporting documentation that supports the grounds on which the protest is based; and (d) The relief sought. All four of the above criteria must be met. Energy Wise Services' protest contains sufficient information to identify the solicitation that is the subject of the protest. However, Energy Wise Solutions has not challenged the solicitation document as unnecessarily restrictive, legally flawed or as improperly specifying a brand name. Nor has Energy Wise Services presented grounds to demonstrate that the procurement process is contrary to law. The Board must decide if Energy Wise Services has met ORS 279B.405(4)(b). Energy Wise Services' protest letter sets forth several factors which it states the County did not give sufficient weight to its proposal. These generally include that their proposal provides more value to the County in terms of simplicity, reliability, cost savings, and system size. The Board must decide if Energy Wise Services has met ORS 279B.405(4)(c) and (4)(d). 2. ORS 279B.410 ORS 279B.410 states, in relevant part: (1) A bidder or proposer may protest the award of a public contract or a notice of intent to award a public contract, whichever occurs first, if: (a) The bidder or proposer is adversely affected because the bidder or proposer would be eligible to be awarded the public contract in the event that the protest were successful; and (b) The reason for the protest is that: (A) All lower bids or higher ranked proposals are nonresponsive; (B) The contracting agency has failed to conduct the evaluation of proposals in accordance with the criteria or processes described in the solicitation materials; (C) The contracting agency has abused its discretion in rejecting the protestor's bid or proposal as nonresponsive; or (®) The contracting agency's evaluation of bids or proposals or the contracting agency's subsequent determination of award is otherwise in violation of this chapter or ORS chapter 279A. (2) The bidder or proposer shall submit the protest to the contracting agency in writing and shall specify the grounds for the protest to be considered by the contracting agency. The Board must consider whether the stated reasons for Energy Wise Services' protest are cognizable under ORS 279B.410(1)(b) and whether Energy Wise Services has specified the grounds for the protest in accordance with the statute. Energy Wise Services' protest letter does not allege that E2 Solar's proposal is nonresponsive, nor that the County failed to evaluate the proposals in accordance with the RFP materials. The County did not reject Energy Wise Services' proposal as nonresponsive; however, during the scoring process it was noted that the required Exhibit C: Signature Sheet was not included with their proposal. Energy Wise Services was not notified that their proposal was incomplete considering that their proposal was scored 6`h out of the seven (7) proposals. Energy Wise Services has not alleged that the County's evaluation of proposals is "otherwise in violation" of ORS 279B or ORS 279A. 3. ORS 279B.060(8) ORS 279B.060(8) provides discretion to the Board in evaluating proposals submitted in response to an RFP. It states that a contracting agency (the Board) may evaluate proposals on any of the following bases: (a) An award or awards based solely on the ranking of proposals; (b) Discussions leading to best and final offers, in which the contracting agency may not disclose private discussions leading to best and final offers; (c) Discussions leading to best and final offers, in which the contracting agency may not disclose information derived from proposals submitted by competing proposers; (d) Serial negotiations, beginning with the highest ranked proposer; (e) Competitive simultaneous negotiations; (f) Multiple -tiered competition designed to identify, at each level, a class of proposers that fall within a competitive range or to otherwise eliminate from consideration a class of lower ranked proposers; (g) A multistep request for proposals requesting the submission of unpriced technical submittals, and then later issuing a request for proposals limited to the proposers whose technical submittals the contracting agency had determined to be qualified under the criteria set forth in the initial request for proposals; or (h) A combination of methods described in this subsection, as authorized or prescribed by rules adopted under ORS 279A.065 (Model rules generally . The Board exercised its discretion to evaluate the proposals based solely on the ranking of proposals, consistent with ORS 279B.060(8)(a). BUDGET IMPACTS: Costs for the Solar PV Project are budgeted within the Courthouse Expansion project. RECOMMENDED MOTIONS: The Board has several options at the conclusion of the staff presentation and Energy Wise Services protest. The Board may: • Hold the oral and written record open and continue the hearing to a date certain • Close the oral record and hold the written record open to a date certain • Close both the oral and written record and set a date certain for deliberations • Close both the oral and written record and begin deliberations If the Board decides to deny the protest, staff will prepare a proposed Order Denying Protest for Board signature.

CUMMING Building Value Through Expertise DESCHUTES COUNTY FAIRGROUNDS SOLAR PV RFP r- Deschutes County Fairgrounds Solar PV System RFP Addendum #1 d/2d/24 The purpose of this addendum is to publish the answers to questions received from interested proposers prior to the questions/clarification's deadline of R/21/24 Questions and Responses are as follows. 1. Can we schedule a site visit for my electrician to look at the electrical room and get on the roof? ANSWER: Yes, we have scheduled a non -mandatory site visit for anyone interested on September 51" at 9am. 2. The RFP states the goal is to install as much PV as possible for the budget of $640K. Do you want that proposed solar capacity outlined in the Proposal? ANSWER: Please provide a summary description of the size of system you can provide for the set budget of $640K. 3. If the SE facing tilted roofs on the Conference Center (South and Middle Sister buildings) are filled up and there is still room in the budget for more solar, do you prefer installing some on the flat roof between the two buildings (ballasted system, estimated 5-6 psf added) or over on the North Sister? ANSWER: If that occurs we will likely use the flat roof between South and Middle Sister. We will discuss further after the solar contractor has been selected. Deschutes County — County Fairgrounds Solar PV System — Addendum 1 Pa g e 11 4. Warranty on inverters required stated in the RFP is 25 years. Is an extendable warranty up to 20 years acceptable or is 25 years required? ANSWER: It is a goal of this project to have a good quality, long lasting system from a manufacturer with a proven track record. It is our understanding that the specs described in C1.0.#12 of the RFP are available on the market. If you cannot provide products that meet these requirements please clarify exactly what you intend to use and what their specs are. S. There is a design provided by Mayfield in the RFP (that does not meet the RFP requirements for the system), but it is understood this is a Design/Build contract. Can the solar contractor propose an alternative interconnection method other than designed in the Mayfield design with the step-up transformer and 480V inverters system? ANSWER: If you deviate from the specified requirements in the RFP you must state why you are deviating and describe in detail what you are proposing. 6. Can you add to the list one months electrical bill for the 2 Conference Centers, the First Interstate Building and the Arena. Was the First Interstate Building that looks like it has an existing solar system on it looked at for additional solar? If you can't send an electrical bill (a bill would be best) can you give us a $/kwh rate not including any base meter fee or any KW demand costs for each building, and what if any yearly escalator we might use in electric rates if we want to propose more. ANSWER: I will try to get a copy of a recent electrical bill of the South/Middle Sister building before our site walk on Sept 511. The arena/first interstate building is not included in this project. i. "as a structural engineer determined how much weight the flat and sloped roof can hold of the Conference Center. It wouldn't make sense to spend time money and effort to bid on something, pay the bond... and then find out the roof isn't strong enough. This should be paid by the county before the bid. For the flat roof, a typical solar system weighs around 4.2 Ibs/ft2, for sloped roofs about 2.2 Ibs/ft2. ANSWER: The County will coordinate with the structural engineer to make sure the roof has the capacity for a new solar system. 8. The solar module (panel) restrictions are very tight and would mean a very small handful of solar panels would be approved. Even some that are at 90% output in 25 years, are not less than .025% drop in efficiency per year. ANSWER: See answer to #4 and #5 above. 9. A 25 year product warranty on the solar panel or inverter doesn't mean that much as many companies go out of business in 25 years. As we have replaced 11 solar panels out of about 45,000 installed over the last 14 years, I don't put much stock into very long warranties, the same goes for the inverters. ANSWER: See answer to #4 and #5 above. 10. Solaredge is the main inverter company that has a 25 year warranty, stock price has gone from a high of $362 a few years ago to $23.66 today. Most string inverter companies have a 10 year warranty, I would suggest rather than paying extra to gamble on any company will be around in 25 years, one could simply Deschutes County — County Fairgrounds Solar PV System — Addendum 1 P a g e 12 buy extra inverters, that way no matter what happens to the company one would be set for the life of the solar system. ANSWER: See answer to #4 and #5 above. 11. Assuming one puts in higher than the 191 kw, can we place an alternate bid with modules that are less than 90% output in 25 years output, the typical ones are 83-84% in 25 years, but maybe $35,000- $40,000 less expensive. Basically it could make sense to take off some of the restrictions and see what best deals one can get from the bidders. ANSWER: See answer to #4 and #5 above. 12. Under the "Request for Proposal" section C1.0, 12. 1 cannot find a Solar panel with a 25 year product and labor warranty. Typically, the product warranties are 10 to 12 years. Also, I cannot find a module with a 0.25% annual degradation. Most are 0.45% to 0.50%. ANSWER: See answer to #4 and #5 above. 13. The Mayfield report uses Q.Peak 480W. They have a 0.45% degradation rate - typical. They also only have a 12 Year product warranty. ANSWER: See answer to #4 and #5 above. 14. The Inverters are shown to require 25 year warranty under section C. Solaredge can only be extended to 20 years max. Other inverter brands are only 15 years max, ANSWER: See answer to #4 and #5 above. 15. On the Request for Proposal document under C1.0 Scope of Services, 12, D it states the Solar panel size to be 430 watt maximum. The mayfield report uses Q.Peak 480W modules. Can we propose larger wattage modules beyond the 430W limit or will that lower our score? ANSWER: See answer to #4 and #5 above.

The aim of this study is to generate a concept rooftop PV system design that meets the GET requirements while maximizing financial return over its lifetime. Our analysis includes an evaluation of the site to identify construction and electrical interconnection hurdles. This report provides substantial information that can be used for bid documents, bid specifications, and is the foundation for engineered drawings, construction, commissioning and performance validation. If goals, loads, tariff rates, equipment or construction logistics change over time, edits can easily be made to the concept design to adjust for a smooth successful implementation. The following goals and benchmarks were used during the system modeling: • Create and analyze a base model of electrical energy consumption and PV generation with the greatest possible financial return • Analyze past utility records to generate synthetic load profiles and verify utility rate structure • Develop a concept system design with a guaranteed maximum price of $600,000, including schematic drawings (Site Plan, Single -Line Diagram) and data sheets for major components • Provide final report as deliverable • Project lifespan is 25 years, typical of PV • Provide written system description for RFP • Analyze feasibility of battery storage, either now or in the future Based on our analysis, Mayfield presents a 191.5 kWDC rooftop PV system on the conference center facility that will offset 70% of annual electrical load at that meter. This concept design utilizes reliable and widely available equipment with multiple equivalent market alternatives, and represents an elegant design that maximizes return on investment compared to other options examined. If desired, the conference center and auditorium are capable of supporting additional PV capacity, beyond our concept design. The arena, while electrically capable of supporting additional PV capacity, is not recommended. Our modeling suggests suboptimal financial return for installation on this larger facility, due to a less favorable utility rate structure that cannot be modified. Site Information & Limitations 2.1 Site Description & Existing Electrical System The Deschutes County Fairgrounds is located at 3800 SW Airport Way, Redmond, OR 97756. There are nineteen Pacific Power electrical services on the premises, including three under consideration for this study: 5 Notok Mayfield jjj Renewables- Deschutes County Fairgrounds - PV Feasibility Report Table 1: Electrical Service Summary Site Name Meter Number Rate Schedule Service Type Service Size (A) Xfmr Size (kVA) *Annual GWh demand Indoor Arena 85868373 30-135 480Y/277 3,000 1,000 0.671 Conference Center (Middle & South Sister) 85868371 28 208Y/120 3,000 750 0.414 Auditorium (North Sister) 75456300 28 208Y/120 2,000 j 300 0.299 * Estirnated,from Pacific Power utility bills, May 22 - Jan 23, and Mar 23 - May 23 Figure 1. Deschutes County Fairgrounds, annotated site map Roof area suitable for additional PV is plentiful, totaling roughly 50,000 sq ft. All three buildings under consideration have 2/12 pitch standing seam metal roof areas oriented at 135' azimuth, and the auditorium has a similar section of roofing with an azimuth of 225°. In addition, the conference center has an area of low -slope roof acting as a bridge between the Middle and South Sisters sections, a portion of which is free of obstruction. I Mayfield jjjRenewables- Deschutes County Fairgrounds - PV Feasibility Report Figure 2. Available roof space with suitable PV tilt and azimuth; purple areas indicate possible PV locations The indoor arena facility meter (#85868373) is billed per rate schedule 30, and is a 3,000A, 480Y/277V service fed by a 1,000 kVA General Electric transformer. A 100A breaker in the main panel acts as the POI for the existing 65 kW PV system on the east section of its main south -facing roof plane, installed in 2013 by E2 Solar.

The conference center meter (#85868371) is billed per rate schedule 28, and is a 208Y/120V service fed by a 750 kVA transformer. It also has a 3,000A Siemens main distribution panel that serves ten subpanels. Four 225A breaker spaces exist at the bottom of the bus —see site limitations section for more information. This roof has adequate, unobstructed space sufficient for the addition of up to approximately 250 kWDC of PV Estimated annual load at this building is 414 MWh, which exceeds its PV capacity. Similar to the conference center, the auditorium's meter (#75456300) is billed per rate schedule 28, and is a 208Y/120V service. It is fed by a 300 kVA transformer, and has a 2,000A Siemens main distribution panel. The auditorium roof has adequate, unobstructed space sufficient for the addition of up to 150 kWDC of PV Estimated annual load at this building is 299 MWh, exceeding its solar generation capacity. 2.2 Site Limitations Free breaker space in the main distribution panel allows a newly installed PV breaker to act as the interconnection point between a new PV system and the utility grid. Space at the bottom of the main busbar snakes possible —generally speaking —the interconnection of a larger solar system, as compared with breaker space higher up the bus. However, the size and configuration of the available breaker space are important factors. While roof space is plentiful, some electrical constraints must be considered. The auditorium (North Sister) has the smallest electrical service at 2,000A, and lacks suitably configured available breaker space. A supply-side PV interconnection could circumvent this limitation in the main switchboard, however. 0 Mayfield Renewables- Deschutes County Fairgrounds - PV Feasibility Report The arena's larger main panel has available breaker space, making either a supply-side or load -side connection feasible. However, because the arena's underlying rate schedule (30) provides a lower base electricity charge than the schedule that applies to the conference center and auditorium, the potential financial return of solar PV at this location is significantly less favorable. In the course of our investigation, Pacific Power confirmed that the underlying rate schedule cannot be changed. For this reason, the arena should be the last option considered for net metered PV, when optimizing for return on investment. While there are four free 225A breaker spaces located in the conference center's main panel opposite the 3,000A service disconnect, they are not ideal for interconnection of a larger PV system. While it would be technically feasible to host up to four smaller PV systems, each with its own breaker disconnect, this would require as many inverters, PV AC disconnects, and drawing sets. However, as at the auditorium, a single PV interconnection is possible as a supply-side connection between the meter and main OCPD. Methodology The following outlines the methodology and data used to model and optimize the system to meet the goals and performance requirements for the installation of a PV system at the Deschutes County Fairgrounds. The study utilized Xendee optimization software to inform the system architecture and multiyear financial model. Helioscope software was used for PV system annual production based on design power losses and system degradation. 3.1 Electrical kWh Load Profile As the foundation of any optimization, due diligence must be taken in creating an accurate load profile to ensure precise modeling that determines lowest net present cost while meeting project goals. Key aspects in data collection are outlined below: • Deschutes County provided past Pacific Power electricity bills for the three meters under consideration in this study. Bills were provided for the period spanning May 2022 through May 2023, except for February, 2023. • From these data, Mayfield constructed a synthetic load profile for the arena and conference center buildings. A medium office NREL end -use load profile in an ASHRAE 5B climate type (cool -dry, similar to Boulder, CO) was selected and scaled to represent electrical demand at the conference center. For the arena, we constructed a custom load profile to reflect a more variable special events schedule. 3.2 Tariff Rate Structure The arena is on the schedule 30 tariff rate, and the conference center and auditorium are on schedule 28. It is assumed that electricity purchased from Pacific Power will have an escalation rate of 4% per year. Since demand charges are fees associated with infrastructure, such as improvements and maintenance of transmission and distribution lines, these demand rates still remain and are also assumed to have an annual escalation rate of 4%.

No such hurdles were identified during our investigation. Net metering occurs under schedule 135, which allows a maximum export of 2 MW at each meter. Meters at the same property may be virtually aggregated, and net metering credit at one meter can therefore be applied to multiple meters —including meters with differing underlying base rate schedules. However, our analysis of building load and PV generation potential indicate that aggregation will not be required to maximize financial return, even if all roof space on all facilities is fully utilized. 3.4 System Parameters Xendee and Helioscope modeling of PV system designs was performed with the following parameters: Equipment: • Modeled with Hanwha Q Cells, Q.Peak DUO XL-G10.2 48OW modules and SolarEdge SE66.6KUS and SEl00KUS three phase 480Y/277V inverters o Datasheet (Appendix D), warranty degradation, production levels and efficiency used in Helioscope (Appendix C) • Helioscope production report imported into Xendee • 16.6 degree tilt angle for flush -mounted subarrays on 2/12 pitch standing seam roof sections with azimuth of 135' Project: • Project lifespan: 25 years • Electrical export allowed • Cost of installation ($/W) on the two facilities analyzed: o $3.125/W for conference center o $3.000/W for arena • $0.40/kW annual maintenance cost (module cleaning) • 30% ITC eligibility (using IRA direct pay) • No MACRS eligibility • Electricity rate inflation: 4% • Financing discount rate: 5% I Mayfield Renewables- Deschutes County Fairgrounds - PV Feasibility Report o Assumed a partial cash purchase for multi year financial model Final System Architecture Utilizing Helioscope and Xendee, Mayfield designed a 191.5 kWDC system architecture to meet project goals while taking into account solar resource, electricity prices, installation costs, total capital expense, operating and maintenance expense, and equipment degradation. Several iterative designs and analyses led to our suggested system architecture on the conference center facility. Our optimization took into account product availability, and reflects a realistic and robust design: • 191.5 kWDC / 166.6 kWAC PV system • (399) Hanwha Q Cells, Q.Peak DUO XL-G10.2 48OW modules o Flush mount racking tilted at 16.6 degrees • (1) SolarEdge SEl00KUS string inverter, 480VAC 3p • (1) SolarEdge SE66.6KUS string inverter, 480VAC 3p • (202) SolarEdge P1100 optimizers, one per two modules in series • (1) 225 kVA 208Y-4800 step up transformer See single line diagram (Appendix B) and system layout (Appendix A) for bid -ready design package. 4.1 Product Description: Our chosen PV modules and inverters are Tier 1 products, widely available from any EPC. Equivalent Tier 1 alternatives exist, and should be considered and evaluated based on RFP responses. High quality Hanwha Q cell modules have a module efficiency of 21.6%, a 12-year product warranty and 25-year linear performance warranty down to 86%. SolarEdge 480VAC 3p inverters and P1100 optimizers are capable of module level monitoring, have a 20 year extendible warranty, and can be configured for use with SolarEdge Data Logger, an environmental data acquisition system. 4.2 Point of Interconnection: Because insufficient breaker space exists in the conference center main switchboard, a supply-side connection between the meter and main OCPD will be required. The meter CT is currently located inside the main panel. While a connection within the panel itself is possible, it would require further engineering analysis. Alternatively, the existing utility meter CT can easily be moved, and a connection made outside of the main panel chassis. 4.3 Consumption Offset & PV Exnort: Our 191.5 kWDC flush mounted PV system design is mounted on three roof planes, all oriented at 16.6° tilt and 135' azimuth (SE). The system is estimated to produce a total of 287.7 MWh annually, offsetting 70% of the conference center's estimated annual consumption of 414 MWh. PV export is the anticipated export of the renewable resource to the grid that is not consumed by the facility at the time of production. However, this is credited to the account and then used at a later time or date, therefore not negatively affecting return on investment. The total anticipated electricity export is 88,791 kWh onto the utility grid. 10 0141*1 Mayfield Renewables- Deschutes County Fairgrounds - PV Feasibility Report ` A • Electricity Consumed On -site 201,322 Electricity Exported 88,791 Total 290,113 Figure 3. PV power direct consumption vs. credited power export Multiyear Financial Model 5 1 Capital Expense and Operating Expense: Deschutes County's financial goals in pursuing an additional PV system for the fairgrounds facilities revolve around the 1.5% GET requirement, whereby the County is presently required to allocate $600,000 for renewable energy infrastructure. Mayfield Renewables worked backwards to produce a quality PV system design based on years of engineering experience that meets this target project budget while maximizing financial return over the system lifetime. The total estimated capital expense of $600,438 includes all PV related site prep, prevailing wage labor, bond, insurance, soft costs, engineering, materials, equipment, and operation & maintenance expenses, but excludes cost of money for financing. O&M consists of annual PV module cleaning, estimated at $1,000 per year. 5.2 System Parameters for Multiyear Financial Model: To accurately portray a multiyear financial model the following set points were included in the analysis: Mayfield JJJRenewables- Deschutes County Fairgrounds - PV Feasibility Report • Upfront Cash Purchase Assumed • Project Life: 25 years • Cash Flow Discount Rate: 5% • PV degradation: 0.7%/yr • Annual Demand Rate Escalation: 4% • Annual Energy Charge Escalation: 4% 5.3 Multiyear Financial Model: The below graph shows the multiyear financial analysis with revenue streams over the 25-year project lifespan. In the investment year (year zero), the capital expense is $600,000.

Model parameters remained largely unchanged, with several small adjustments: • A smaller installation cost of $3.00/W, because the array exists on a single roof plane • A therefore slightly larger system size of 200 kWDC • Lower base electrical rates, as a result of enrollment in Pacific Power schedule 30 Modeled financial returns for the arena over the 25 year project lifespan can be compared with results for the conference center, above: • System payback in 19 years • IRR of 2.69% • NPV of discounted cash flows of-$109,020.00 at end of system lifetime. • Total operating expense savings of $618,450.00 over 25 years, or 15.77% annually Table 3: Side -by -side comparison of financial return for four modeled system architectures Lifetime Annual Installation PV Size BESS Size Duration Yrs to Lifetime OPEX OPEX Location (kW) (kWh) (yrs) Payback IRR NPV Offset Offset Conference Center 191.5 - 25 13 6.38% $75,000 $977,490 44.50% Arena 200 - 25 19 2.69% -$109,020 $618,450 15.77% Conference Center (w/ BESS) 90 440 15 N/A -1.94% -$192,110 $336,720 33.94% Arena (w/ BESS) 124 330 15 N/A -7.53% -$295,860 $194,280 11.72% 13 IM Mayfield Renewables- Deschutes County Fairgrounds - PV Feasibility Report Feasibility of Battery Storage Our concept PV design does not exceed the annual electrical consumption of the Pacific Power electric meters of the auditorium, arena, and conference center. This means that all of the energy generated by solar contributes to the financial return of the system. A battery system, in the absence of time of use rate schedules geared towards energy arbitrage, can only generate revenue by offsetting demand charges. Demand charges account for roughly 20% of Deschutes County Fairgrounds' electricity costs, snaking a battery storage system less financially potent than PV alone. If energy resilience —the ability to use electricity during a grid outage —is not a primary goal, we do not recommend pursuing battery storage. Electrically, adding battery storage to a PV system is feasible at all three facilities. Based on our preliminary modeling in Xendee, a $600,000 investment in solar plus battery storage at the conference center with a targeted four hour resiliency window would result in a system architecture of approximately 90 kWDC PV and 11 OkW/440 kWh of battery storage. A key difference with our PV optimizations is the project lifetime, which is limited to 15 years due to the shorter lifespan of battery technology. The project would result in the following financial metrics: • No system payback during 15 year battery lifetime • IRR of -1.94% • NPV of discounted cash flows of-$192,110.00 at end of system lifetime • Total operating expense savings of $336,720.00 over 15 years, or 33.94% annually A similar alternative investment at the arena would result in a system architecture of roughly 124 kWDC PV and 80kW/330 kWh of storage. The project would result in the following financial metrics: • No system payback during 15 year battery lifetime • IRR of -7.53% • NPV of discounted cash flows of-$295,860.00 at end of system lifetime • Total operating expense savings of $194,280.00 over 15 years, or 11.72% annually Determining optimal battery storage system size would require a detailed load analysis (e.g. one month of measurements using eGauge system, or similar) and a formal interview of the Deschutes County team to identify granular storage -related goals. These activities are outside of the scope of the present study, but could be the subject of further investigation. Final Comments 7.1 Construction Hurdles Mayfield does not expect major construction hurdles that would prevent installation of rooftop solar on the fairgrounds conference, auditorium, or arena. However, EPCs should take note of several site conditions that could impact particulars of the final system design and construction process. As mentioned above, the interconnection will need to be a supply-side connection. This will require coordination with Pacific Power to shut off power during installation, so that the solar can be safely connected to the service. 14 Mayfield Renewables- Deschutes County Fairgrounds - PV Feasibility Report Additionally, the lack of available wall space in the main electrical rooms means that PV inverters must be mounted elsewhere. Our design for the conference center suggests a shaded area on the southwest -facing exterior wall (see system layout, Appendix A). Selected inverters must be rated for outdoor installation, and manufacturer specifications and warranty requirements should be followed. Finally, a structural engineering analysis should be completed for all roof sections on which solar will be installed. The engineer may find that structural reinforcement is required on some, or all, roof sections for PV installation. Structural analysis and reinforcement costs will increase the price -per -watt of the project. The low -slope section of the conference center is not utilized in our concept design layout, but may be utilized for additional PV deployment at the discretion of Deschutes County and the selected EPC. If this is a barrier to increasing system size, more favorable economics may be achieved by instead placing the additional PV capacity on the auditorium. 7.2 Conclusion This report provides an optimal PV preliminary design to meet Deschutes County's project goals. A 191.5 kWDC PV system on the rooftop of the Deschutes County Fairgrounds conference center facility provides maximal financial return while satisfying the County's required 1.5% GET investment in renewable energy. The preliminary system design demonstrates a robust possible architecture using readily available high quality electrical components.

Fairgrounds solar bid Energy Wise Services Peter Greenberg nrawiseservice angmail.com 541-905-2271 www.energywiseservices.com Greetings, would like to protest the intent to award for Document No. 2024-811, a Notice of Intent to Award Contract to E2 Solar. The paperwork says there are 7 days from the day of the Commissioners meeting, 10/2 to protest. I asked for a copy of the scoring and a copy of the winners proposal. As the bid is not based on cost, I can't determine if my bid is better than that of E2 Solar or not. I was refused the paperwork asked for until a contract is signed. That could be after the 7 days period. I did hear on the recording of the Commissioners meeting that the size of the system is 310 kw. My proposal was 356 kw. The Mayfield study for the bid is outdated and only talked about 190 kw, prices have dropped over the years. In addition the inverter and the modules he proposed didn't meet the qualifications of the "design build". The solar panels I have proposed along with the racking will qualify for an extra 10% or about $65,000 of free federal money, this is in addition to the 30% of the project cost thru the federal Inflation Reduction Act. The solar panel manufacturer is in the process of building a factory to manufacture solar cells that will meet requirements of the IRA additional grant some time next year (well within the timeline outlined in the bid -before the courthouse is finished). As I am the first customer in the state to use this particular racking, I wonder if E2 Solar will have products that are eligible for this extra 10% of free money. The bid called for inverters with a 25 year warranty. The only inverters that I know of that have this are microinverters. I would not recommend using them as it puts a lot of electronics that can fail underneath difficult to get to areas in a harsh environment. offered a warranty on the output of the system where I would pay for any lost energy between the time a part failed and when we would fix it. offered a spare inverter, so any change could be done very quickly. With the string inverter I have proposed and my design there would be no need to put any electronics under the solar panels, which would be needed in any other proposed system that did not offer the products I would use. The inverter I have proposed can easily be changed (less than 1 hr), if the inverter failed and the manufacturer went out of business, one can use a number of other inverters. If Solaredge fails and goes out of business, there is no other alternative other than to take up all of the solar panels and modify the system which would be very expensive. My proposal includes 10 years of once a year washing of the solar panels and systems check as well as daily monitoring for the first 10 years of the energy output. With what looks like a minimum of $250,000 (at 4% Pac Power annual rate increase) plus the extra IRA funds and the other benefits, I would like to see how the E2 Solar bid is better. pdt,rt, hattlt October 3, 2024 My bid w/ Solis inverters E2 solar w/ Solaredge 480v? inverters 356.5 kw DC 310 kw Year Solar panel output 4% inc/yr Pac Power Initial kwh produced Earnings/yr Initial kwh produced Earnings/yr 1 100% 0.10 518,534 $51,853 468,455 $46,846 2 98.00% $0.104 518,534 $52,849 468,455 $47,745 3 97.68% $0.108 518,534 $54,781 468,455 $49,490 4 97.35% $0.112 518,534 $56,784 468,455 $51,300 5 97.03% $0.117 518,534 $58,860 468,455 $53,175 6 96.71% $0.122 518,534 $61,011 468,455 $55,119 7 96.39% $0.127 518,534 $63,242 468,455 $57,134 8 96.07% $0.132 518,534 $65,554 468,455 $59,223 9 95.75% $0.137 518,534 $67,950 468,455 $61,388 10 95.43% $0.142 518,534 $70,434 468,455 $63,632 11 95.12% $0.148 518,534 $73,009 468,455 $65,958 12 94.80% $0.154 518,534 $75,678 468,455 $68,369 13 94.49% $0,160 518,534 $78,445 468,455 $70,869 14 94.18% $0,167 518,534 $81,313 468,455 $73,460 15 93.87% $0,173 518,534 $84,285 468,455 $76,145 16 93.56% $0.180 518,534 $87,366 468,455 $78,929 17 93.25% $0.187 518,534 $90,560 468,455 $81,814 18 92,94% $0.195 518,534 $93,871 468,455 $84,805 19 92.63% $0.203 518,534 $97,303 468,455 $87,905 20 92.32% $0.211 518,534 $100,860 468,455 $91,119 21 92.02% $0.219 518,534 $104,547 468,455 $94,450 22 91.71% $0.228 518,534 $108,369 468,455 $97,903 23 91Al% $0.237 518,534 $112,331 468,455 $101,482 24 91.11% $0.246 518,534 $116,437 468,455 $105,192 25 90,80% $0.256 518,534 $120,694 468,455 $109,038 $2,028,387 $1,832,489 this doesn't include up to 2% drop for Difference $195,898 transformer no transformer needed Deschutes Co. Fairgrounds solar bid Energy Wise Services Peter Greenberg nrgwiseservicg ,cQgmail.Qom 541-905-2271 Greetings, My name is Peter Greenberg, thank you for allowing me the time to discuss the recent solar bid. Let me introduce myself, I have 14 years experience in the solar business, we have installed approximately 14,000 kw and over 45,000 solar panels. We own approximately 150 solar systems, have installed 20 new solar products and have a good idea of what works and what doesn't. In addition I was a firefighter paramedic for 11 years first as a volunteer with Corvallis, then as a paid professional with Albany. realize it is difficult to know about every type of industry and product. The County had a study by Mayfield,a very good consultant, yet the bid didn't follow most of what they suggested. Their study is now out of date with regards to cost and the materials they suggested would not qualify by the very strict requirements in the bid. If as stated, the intent of the bid was to maximize the size of the solar system, this was not done, because you did not pick the bid with the largest solar system size. The scoring was very subjective and there was little consideration to which bid offered the best value to the County. There was no explanation of how the points were determined. This was supposed to be a design build bid, but with the very tight specs, it was extremely limited to the products that could be used. With the wealth of experience of companies in the industry, one should have simply asked the solar contractors for their best recommendation for the largest system that would give the most value to the County. Some of the issues, I see problems with are: 1. There were 7 days from the day of the Commissioners meeting and the signing of the Intent to Award, 10/2 to protest the awarding of the contract. Typically when one is bidding on price, awards are open immediately after handing them in. In this case we were not bidding on price, instead, from what I understood to be the best value to the County, the bids were not immediately open to the public. I am certainly not a lawyer, but it seems clear to me and common sense would suggest that there is nothing to hide or gain to the county by not sharing this information. ORS 192.311 states, Proposals are not required to be open for public inspection until after the notice of intent to award a contract is issued. Your lawyer said that did not pertain and there was a different statute for road building and engineering that said bids did not need to be disclosed. Whatever the case, there were many faults with the bid process. I was told to file a Request for Records Request, I did that and got a link to the other proposals 7 days and 4 hrs after the Co. meeting on the bid. I heard on the recording of the Commissioners meeting that the size of the winning system is 310 kw. My proposal was 356 kw. 2. The Mayfield study for the bid is outdated and only talked about 190 kw, prices have dropped over the years. In addition the inverter and the panels proposed didn't meet the qualifications of the "design build" bid. 3. In A1.0 of the RFP, it states, "The goal is to maximize the size of the new solar system for the proposed budget." This didn't appear to be the case, as my bid was by far the largest system and had other benefits. 4. Extra money for the county. The solar panels I have proposed along with the racking will qualify for an extra 10% or about $65,000 of free federal money, this is in addition to the 30% of the project cost thru the federal Inflation Reduction Act. My bid was the only one to offer that. 5. The bid called for inverters with a 25 year warranty. The only inverters that I know of that have this are microinverters, it is very rare to see microinverters in larger commercial projects. Regardless of their long warranty, no solar installers I know of would recommend installing almost 800 microinverters under solar panels, as no one would buy something that goes under solar panels that can last 25+ years or longer without this warranty. Microinverters or any electronics can fail and as they are underneath solar panels they can be costly to get to and replace.. In fact none of the bidders other than the winner, included these types of inverters. Elemental Energy, one of the bidders and an excellent long time solar company in Oregon, have got to be the Kings of Enphase microinverters, being a large user of them for many years, they did not put these in their bid. All of the other bidders except mine and the winners proposed Solaredge (string) inverters. As in the Enphase microinverter, Solaredge also only operates with a proprietary device under all of the solar panels that can and do fail. I do not recommend these either. I feel using a proprietary product that cannot be substituted with any other and relying on it to be perfect for decades is not the best value for a customer and can cause major issues and expense if the products fail and the company goes out of business. Uniquely, my bid proposed an inverter that can be easily replaced with other brands, if the inverter fails and the manufacturer goes out of business, the inverter can easily be changed in an hour or 2. There are no electronics under the solar panels with my bid, which can and do fail and provide added risk with little benefit. If the Enphase or Solaredge inverters that all the other bidders proposed fail and the manufacturer goes out of business, there is no other alternative other than to take up all of the solar panels and modify the system which would be very expensive, cost easily over $150,000 to take out the micro inverters or optimizers, replace the inverter with a type I proposed and then reinstall all of the solar panels. 6. 1 offered by far the best and longest labor and production warranty where I would pay for any lost energy between the time a part failed and when we would fix it. My proposal includes 10 years of once a year washing of the solar panels and systems check as well as daily monitoring for the first 10 years of the energy output which no one else offered. 7. Large long term financial difference. Figuring in a 4% Pacific Power yearly rate increase (which has been much more the last few years), the depreciation in output of the solar panel I offered and the system size difference, my bid would provide almost $346,000 in savings over the winning bid over 25 years, including the extra $65,000 from the IRA funds. My system is much less prone to risk of product failure and offers the simplest fix if the product manufactures go out of business. 8. The Meyers Berger solar panels that are in the winners bid do have a very high output after 25 years. Unfortunately the company is close to bankruptcy. Their stock traded at $175.40 at the beginning of the year. As of 10/12/2024 they were at $1.76. Solar panels are basically a commodity, to put large stock in a 25 year warranty and not consider the long term financial status of the manufacturer or energy savings over the life of the system, makes little sense to me. The solar panels I have proposed are US made, they are close to finishing a factory in So. Carolina. Next year they will qualify for a Made in America IRA bonus, along with the racking I proposed, which would mean an additional $65,000 to the county through the Inflation Reduction Act. No other proposal offers this. 9. The winner's bid has wages priced below prevailing wages. The Materials Handler rate in Region 4 from the July 2024 BOLT wages is $36.47, E2 has $32 for an installation technician, this rather than what I have as simply BOLT mandated wages should disqualify their bid altogether. Why scoring wages was part of the scoring is a mystery to me. It makes no sense to score billing rates and fees in a fixed price bid. 10. There was too much significance placed on the scoring, which was very subjective, rather than the best value for the County. To score a 10 on references from one person and a 7 from another is practically meaningless. Contrast this with savings of almost $350,000 more from bid to the winnders. To put scoring on one's team is mostly irrelevant, as one can see from anyone's list of projects that all of the companies are capable of doing this project. With the deadline to finish being before the Courthouse project is done, whether one finishes in 3 weeks or 5 weeks makes little difference. 11. 1 don't understand the scoring for Approach. I scored less than the winning team, yet my approach is more practical, saves more energy and money, uses less equipment that can fail, and offers services that others don't offer over 10 years. 12. Scoring on Team is included, who cares what the team is as long as the job gets done, good materials are used and the project is approved by the AHJ and the ETO. 13. Adding additional connections and electronics thru microinverters under 800 solar panels simply adds more to the risk of failure of equipment than not having it. The majority of failures are caused by faulty cabling and connections, which are factors that can occur in any electrical system. Enphase has a decent reputation but with no national reporting system on inverter failures, there is no way of knowing what is happening with failures. Enphase stock from 2014 to 2020 never went above $10. All of a sudden after the rapid shutdown code changes they pushed, they rose to $319 in November 2022. From Dec. 2022 to then 10/21/2024 they went from $319 to about $90.17.

The treatment facility and associated wetlands complex will provide an environmentally sound and sophisticated solution to wastewater treatment and disposal for the City of Redmond as well as the nearby unincorporated community of Terrebonne. We recognize the City's proposal will reduce a portion of area dedicated to OHV and other public use, however the City's proposed wetland complex will significantly expand upon the quality of access, trail development, and other recreational, cultural and wildlife amenities that will enhance and improve upon the public use of this land. We appreciate the Bureau of Land Management (BLM) considering creating additional miles of motorized trails nearby to compensate for any losses and developing additional non -motorized trails. Overall, this wastewater treatment facility and wetlands complex will provide significant benefits to our urban and rural communities, businesses, residents and visitors.

The Upper Deschutes Resource Management plan would have to be amended for the BLM to convey the parcel under the Recreation and Public Purposes Act and segregate the lands from all other forms of appropriation except for conveyance. Under the Upper Deschutes Resource Management Plan, the requested 541.5-acre parcel is within the Steamboat Rock Special Recreation Management Area. The area contains five miles of trails designated for Class I and III off -highway vehicles that would be removed from use if the land is conveyed to the city; however, 38 miles of trails would remain within the Steamboat Rock Special Recreation Management Area and the field office will consider adding in additional miles of motorized trail nearby to compensate for this loss.
