Dear Board Members:

Requested Board Action:

Adopt the Resolution Approving the Solar Power and Services Agreement with SunEdison Origination,LLC, to provide solar energy to various County sites.

Background:

The County of Imperial, through its Department of Public Works (DPW) and County Executive Office,has expressed a desire to develop energy efficient practices for County facilities. The County believesthat a Power Purchase Agreement (PPA) for on-site solar power generation will provide a long-termfinancial benefit by reducing energy costs through reduction of peak demand loads and daily energyconsumption at selected County sites. The program will provide high quality power with minimalenvironmental impact. The agreement will have a twenty year duration, with an option to renew for anadditional five years. Through this PPA, the County hopes to:

• Reap the financial benefits of more affordable electricity at a minimal cost to the County.• Reduce environmental impact by the County's energy use.• Provide an example of successful renewable energy generation and showcase the County as a

leader in development of renewable energy sources.

On March 26, 2013, the Department of Public Works (DPW) released a Request for Proposal (RFP) fora Solar Energy Generation Program for County facilities. The RFP was advertised on the ImperialCounty Public Works web site under Projects out to Bid. Five (5) firms submitted proposals by thedeadline of May 16, 2013. Copies of all proposals are on file with the Clerk of the Board.

Proposals were reviewed by County staff with the assistance of a Consultant, Government FinancialStrategies, Inc. (GFSI). A copy of GFSI's financial evaluation of the proposals is attached. The tablebelow shows a comparison of proposed kilowatt hour (kWh) pricing of the five respondents, for the firstyear of the project. The County's current average rate for electricity usage is approximately $0.1159 perkWh.

During the evaluation process, the County was notified that Enfinity had been purchased by SunEdison,LLC; with a statement that SunEdison would honor the pricing offered by Enfinity. The Countyperformed due diligence review of both Enfinity and SunEdison, including background and referencechecks, as well as review of audited financial statements by GFSI, all of which yielded favorableresponses. Both County staff and GFSI recommended Enfinity (acquired by SunEdison), as the mostqualified firm, with the best value pricing for energy purchase by the County

County Counsel Coordination:

This agreement was approved by County Counsel under AR 14-0515 DPW.

Fiscal Impact:

There will be no cost to the County to enter into this agreement. All costs for construction,maintenance and operation of the solar photovoltaic systems will be paid by SunEdison. The Countywill purchase solar energy generated by the systems to supplement the County's energy needs.

Respectfully,

vd IWilliam S. Brunet, P.E.Director of Public Works

Introduction

This report provides a financial evaluation of the responses to the RFP for the County's SolarEnergy Generation Program using quantitative financial metrics. It does not evaluate thecompanies themselves or energy-related criteria such as the quality and performance of theproposed solar energy generation equipment. It also considers the financing structure as calledfor in the RFP (a Power Purchase Agreement) and does not consider the merits of alternativefinancing options.

Summary of RFP Responses

The County received responses from five companies:• SolarCity• SunEdison• PsomasFMG• Enfinity• Amsolar

The companies were asked in the RFP to provide recommendations on solar system sizes forinstallation at the County Administration Center (CAC) and County Jail complex. The chart belowsummarizes the recommended sizes:

The companies were also asked to propose pricing for the solar systems using a Power PurchaseAgreement (PPA). A PPA is a financing structure whereby the County contractually agrees topurchase whatever power is produced by the solar systems, and another company (the PPAprovider, typically a bank or investor) maintains ownership of the solar systems and expects toreceive a return on their investment. Since the County does not own the solar systems under aPPA, the County would not be responsible for operations and maintenance, equipmentreplacement and repair, etc. At the end of the term of the PPA, the County would have the optionto purchase the solar systems (typically, at the market value at the time) or have the solarsystems removed from the County sites.

The County requested that companies provide PPA pricing for the first year of the PPA, assumingthat the PPA price escalated 4% annually over a 20-year term. The chart below summarizes theprices proposed for the first year of the PPA:

Chart 2

The chart demonstrates that Enfinity proposed the lowest PPA pricing while PsomasFMGsuggested the highest PPA pricing.

We also note that three of the companies (SunEdison, PsomasFMG, and Enfinity) indicated theyexpected to receive rebates from the IID Solar Solutions Rebate Program while the other twocompanies (SolarCity and Amsolar) made no mention of the potential rebates. To the extent theserebates are no longer available, or can no longer be obtained at the rebate amounts assumed,this may lead to a negotiation process of the PPA pricing because the vendor may resist awardingthe same pricing without the benefit of the rebates.

Another area of consideration is evaluating whether Enfinity can reasonably deliver on the low PPApricing. PPAs have been a shrinking market in recent years with the decline of rebates and taxincentives. However, Enfinity identifies, among others, Wells Fargo Bank as a source of PPAfinancing, and claims a track record of completing over 200 PPAs. Therefore, it would seemreasonable that based on the RFP response, Enfinity has the experience and financial backing tofollow through on its proposal. While no additional due diligence has been performed at this time,should the County proceed with Enfinity, we would recommend further due diligence to confirm theclaims made in the RFP response.

Analysis of RFP Responses

For comparison against the PPA prices, a baseline of the County's existing energy prices with thelocal utility company, Imperial Irrigation District, was established using a sampling of utility bills.The sampling was intended to create an approximation of what the County currently pays forelectricity, based on reviewing the bills for a variety of buildings and meters at both the CAC andJail during a time of year that is generally high energy usage and a time of year that is generallylow energy usage. The results of the sampling are shown in the chart below:

RFP Response

GovernmentFinancial

Strategiesinc.

The PPA prices were compared to the County's existing electricity prices, utilizing the energygeneration output that was provided by each company in their RFP response. Companies providedenergy generation output using two models:

1) PV Watts: this is a model developed by the National Renewable Energy Laboratory of theU.S. Department of Energy. The County suggested this model be used in the RFP.

2) PVsyst: this is a model developed by a private company of the same name. Somecompanies preferred to include the output from this model because they stated it allowsfor customizing to specific PV technology. Output from high-efficiency modules would beunderestimated using PV Watts, which is designed for standard modules.

For comparison purposes, results were evaluated using both models of energy generation output.One company, Amsolar, did not provide output using PV Watts, and two companies, SolarCity andPsomasFMG, did not provide output using PVsyst.

For the energy generation outputs provided, the estimated total savings was determined for boththe CAC and Jail combined, and using the proposed PPA prices over the 20-year term. Theresults are shown in the chart below:

Chart 4

The chart shows that Enfinity's proposal offers the most savings, followed by SolarCity, Amsolar,and SunEdison. The proposal from PsomasFMG is estimated to result in an increased cost to theCounty rather than a savings, and so is shown in the chart as a negative savings.

Budget Analysis

Since Enfinity's proposal provides the most total savings, this proposal was given a more in-depthevaluation that considers the project's cash flow and how it impacts the budget on an annualbasis. These results are shown in the chart below, assuming output on a PV Watts basis andthat the inflation rate in electricity prices from IID is the same 4% annual rate as the PPA prices:

Chart 5

The chart illustrates the annual savings is estimated to range from a low of $165,000 in the firstyear of the PPA to a high of $315,000 in the final year of the PPA, totaling $4.6 million over the20-year period. These figures are in unadjusted dollars, not discounted for inflation or the timevalue of money.

Risk Analysis

Because it is not possible to forecast with certainty the inflation rate in 110's electricity prices overthe next 20 years, a risk analysis was conducted that considers how the savings to the Countywould change depending on various inflation rates. The savings to the County were determinedassuming that the inflation rate would be 2% annually, 4% annually, and 6% annually over the next20 years. The results of this analysis are shown in the chart below:

Chart 6

The chart demonstrates that even at a 2% annual inflation rate in 110's electricity prices, the PPAwould achieve savings in every year. Savings is estimated to range from a high of $165,000 inthe first year of the PPA to a low of $5,000 in the final year of the PPA, totaling $2.0 million overthe entire term.

If the inflation rate in IlD's electricity prices were 6% annually, the County is estimated to save$165,000 in the first year of the PPA to $755,000 in the last year of the PPA, for a totalsavings of $8.1 million.

The County's break-even rate was also calculated. In a break-even situation, the County mightsave money in some years and have higher costs in other years, but overall achieve $0 in savings.In order for the County to break-even on the PPA, it is estimated that IlD's inflation rate wouldneed to be 0.15% annually on average over the next 20 years.

Strategiesinc.

The underlying assumption required to achieve benefit from the PPA is that energy prices willcontinue to escalate in the future. Therefore, by locking in prices now, the County will avoid therisk of inflation and experience savings over the next 20 years. Should there be deflation in energyprices, so that prices decline over time, the County will not benefit from entering into the PPA.Given the historical record of energy prices though, it is reasonable to assume that absentsignificant technological shifts in energy procurement, prices will continue to generally rise overtime and result in benefit to the County.

Conclusion

Based on a financial evaluation of the RFP responses, we recommend the County proceed withEnfinity because this company's proposal offers:

• The most savings of all the RFP responses, estimated to be $4.6 million over the 20-yearterm of the PPA.

• Positive cash flow, so that savings are expected to be achieved in every year of the PPA,ranging from $165,000 to $315,000 annually.

• Given a range of inflation rates in electricity prices from IID of 2% - 6% annually, theCounty is estimated to save a low of $2.0 million to a high of $8.1 million over the 20-yearterm, and positive cash flow in every year.

• IlD's inflation rate would need to be 0.15% annually on average over the next 20 years forthe County to break even on the PPA (achieve no savings).

• Based on the RFP response, it seems reasonable to conclude that Enfinity has theexperience and financial backing to deliver the terms of the PPA as proposed, althoughfurther due diligence is recommend in this area.
