Deschutes County Code (DCC) 2.36 authorizes the Board of County Commissioners to function as the local contract review board. 2. DCC 2.37 provides that the Model Rules of Public Contract Procedure, OAR 137, divisions 46,47,48, and 49 "shall be the rules of the Deschutes County Contract Review Board." Protest—Claims/Findings: 1. Claim: Energy Wise Services was delayed in receiving the proposals after the issuance of the Notice of Intent to Award. Finding: Energy Wise Services did not meet its burden of proof, in either its written protest document or during its presentation before the Board of Commissioners on October 28,2024, to prove where or how the County's decision to award the Deschutes County Fair and Expo Center Solar PV System contract to an entity other than Energy Wise Services violated any of the applicable protest criteria in ORS, OAR, or DCC. This claim is denied. 2. Claim: The Mayfield study for the bid is outdated, and the inverter and panels proposed did not meet the qualifications of the"design build"bid. Finding: Energy Wise Services did not meet its burden of proof, in either its written protest document or during its presentation before the Board of Commissioners on October 28,2024,to prove where or how the County's decision to award the Deschutes County Fair and Expo Center Solar PV System contract to an entity other than Energy Wise Services violated any of the applicable protest criteria in ORS, OAR, or DCC. This claim is denied. 3. Claim: The stated goal in the RFP of maximizing the size of the new solar system for the proposed budget did not appear to be accurate since Energy Wise Services proposed the largest system and offered other benefits. Finding: Energy Wise Services did not meet its burden of proof, in either its written protest document or during its presentation before the Board of Commissioners on October 28,2024,to prove where or how the County's decision to award the Deschutes County Fair and Expo Center Solar PV System contract to an entity other than Energy Wise Services violated any of the applicable protest criteria in ORS, OAR, or DCC. This claim is denied. Page 3 -ORDER NO. 2024-044 4. Claim: Energy Wise Services was the only bid to offer federal monetary incentives for the proposed racking in addition to the project costs through the Federal Inflation Reduction Act. Finding: Energy Wise Services did not meet its burden of proof, in either its written protest document or during its presentation before the Board of Commissioners on October 28,2024,to prove where or how the County's decision to award the Deschutes County Fair and Expo Center Solar PV System contract to an entity other than Energy Wise Services violated any of the applicable protest criteria in ORS, OAR, or DCC. This claim is denied. 5. Claim: The RFP sought inverters with a 25-year warranty. This can only be found in microinverters,but it is rare to use microinverters on a larger commercial project. Issues, such as proprietary designs and long-term stability of the company issuing the warranty, may arise resulting in long-term issues and expenses. Energy Wise Services' bid proposed an inverter that can easily be replaced with other brands. Finding: Energy Wise Services did not meet its burden of proof, in either its written protest document or during its presentation before the Board of Commissioners on October 28, 2024, to prove where or how the County's decision to award the Deschutes County Fair and Expo Center Solar PV System contract to an entity other than Energy Wise Services violated any of the applicable protest criteria in ORS, OAR, or DCC.

This claim is denied. 7. Claim: The proposal for Energy Wise Services would provide an estimated$346,000 in savings above the winning bid over a 25-year time period. Finding: Energy Wise Services did not meet its burden of proof, in either its written protest document or during its presentation before the Board of Commissioners on October 28,2024, to prove where or how the County's decision to award the Deschutes County Fair and Expo Center Solar PV System contract to an entity other than Energy Wise Services violated any of the applicable protest criteria in ORS, OAR, or DCC. This claim is denied. 8. Claim: The solar panels proposed by the winning proposal are from a company that is on the brink of bankruptcy. If they go bankrupt,the 25-year warranty would be worthless.

Electrically,adding:battery storage to a PV:system is feasible:at all three facilities.Based on Our preliminary modeling in Xendee, a$000,000 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:110kW/440 kWh of battery storage.A key:difference with our PV optimizations is the project lifetime,which is.liinited to 15 years due to the shorter lifespan of battery technology.The project • .: would result in the following financial metrics: ::: • No system payback during.15year battery lifetime :• :NPV of discounted cash flows of-$192,110.00 at end of system lifetime • Total operating expense savings of$336,720.90 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:stora a system size would require a detailed load:anal analysis e. one month of ...g. q Y � g• 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 t'o be a suPp 1 side connection.This will require coordination with y- Pacific Power to shut off.power during installation,so that the solar can be safely connected:to the service.... 1 14 :: . . . 10/28/2024 Item#2. May.fiId Renewable?" 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:maybe: 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 readilyy available high quality electrical components:The attached single line diagram,array layout,. equipment:spec sheets,and RFP system description,when incorporated into a formatted RFP,provide.the detail necessary to successfully solicit bids from qualified contractors.:Mayfield Renewables is capable of: —providing fullyengineered and construction drawings,owner's representative services,and P g � permitg � P commissioning services.

Let me introduce myself, I have:1:4: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 paramedicfor 11 years first as.a"volunteer with Corvallis, . then.as a paid professional with-Albany... .. . .. ... .. . .. . .. : I'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 :i . :. 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 ve•ry tight:specs, it was extremely • • limited to the products that could be used With:the.wealth of experience.of companies:iin 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 rotest the awardingof the contract.:T icall when one:is- . - R. :. YP. Y 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 clearto 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 ofintent to,awar 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 manyfaults with the bid process. :•. :: ' : 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 99 • 10/28/2024 Item• #2. • : 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:panelsI 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 recommendinstalling almost 800 microinverters under:solar panels, asno: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 ell;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:soler 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 proposed_and then reinstall all-Of the solar panels.. : .. 6..I 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 • 100 • • 10/28/2024 Item#2. • 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 longterm financial status of the manufacturer or energy savings over the life of the system, makes little sense tome: The solar panelsI 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 wagee priced below prevailing wages:::The Materials'Handler rate in Region 4 from the July 2024 BOLl wages is$36.47,:E2 has $32 for an installation technician, this . rather than What I have as simply BOLl 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.: V • 11. I don't understand the scoring for Approach::I:scored less than the Winning team, yetmy 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.Addingi 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 byfaulty and connections,_which are factors that:can occur in anyelectrical cabling system. Enphase has a decent reputation but with no national reporting system on inverter • • 101 • 10/28/2024 Item#2. • 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. Solaredge the inverter and optimizer everyone but me and E2 bid on went from $83, 5 yrs ago to$360 a few years ago after the code change to $17.13 today Peter Greenberg Energy Wise:Services ,..,,, _e. . . . 0._. r' 'r , `? ` ^ '.,. a 4`u 10/28/2024 • Item t#2. ;i 4 �_- uv^ a .'o 'e- ap3ftti �vG.- .. - -{ � 458:5 k41 �EWS ..1'�• _ o -` 4.. • 310.44 kv\E2 .
