CITY COUNCIL STAFF REPORT
Meeting: November 1, 2010
Subject
Report on the status of the Solar Power Purchase Agreement (SPPA) project.
Recommended Action
Receive report and provide direction to staff.
Description
The SPPA will allow the construction and purchase of renewable energy from carport
photovoltaic arrays at City Hall, Corporation Yard, and the Quinlan Community Center.
A Solar Power Purchase Agreement (SPPA) is a financial arrangement in which a third-party
developer owns, operates, and maintains the photovoltaic (PV) system and a host customer
agrees to site the system on its roof or elsewhere on its property (i.e. carport structure) and
purchases the system’s electric output from the solar services provider for a predetermined price
and period. Power purchase agreements address many of the traditional barriers to adoption for
organizations looking to install solar systems including high up-front capital costs, system
performance risk and complex design and permitting processes.
Challenges of Siting Renewables
One of the major barriers for local governments in purchasing renewable energy systems is the
high upfront costs involved. Although purchasing a renewable energy system outright is
generally considered to be the most cost effective strategy in the long-term, the high up front
capital costs are often prohibitive. An alternative method of financing has been sought in order to
utilize renewable energy and thereby decrease energy costs. In the past five years, the financial
sector and renewable energy providers have developed innovative third party ownership
financing structures, such as Power Purchase Agreements, to take advantage of the tax incentives
available to the private sector. However, these financing structures require significant legal,
procurement, property management, and engineering expertise to execute and therefore have
high transaction costs that have presented a barrier to local governments.
The Opportunity of Regional Aggregation
In order to reduce the transaction costs associated with Power Purchase Agreements and to
support the diffusion of renewable energy generation, the members of the Joint Venture Climate
Protection Task Force created a regional collaborative procurement, lead by Santa Clara County.
By leveraging the contractual resource investment of the lead agency and creating a procurement
pool, all participating agencies have benefitted by reducing or eliminating the barriers to
adoption of renewable power.
In 2007, a collaboration of Joint Venture Silicon Valley, the Association of Bay Area
Governments (ABAG), and Santa Clara County initiated a program to create a regional
Renewable Power Purchase agreement (RPPA) with the specific intent of enabling an affordable
group purchase of renewable energy. The Department of Energy (DOE) was to later join this
effort.
A RPPA is one model which provides an opportunity to break down both the upfront capital
barriers to direct ownership and the transaction costs associated with third party financing and
move our community and organization forward in renewable energy usage. Additionally, by
creating a regional PPA rather than individual PPAs for each city, the costs of developing the
agreement are reduced significantly for all parties involved. This method not only conserves
funds, but also accelerates the financing process and deployment of renewable energy
technologies, promotes energy and tax-dollar savings, and supports local economic development.
Since the summer of 2008, the collaborative has researched solar power purchase agreement
issuances, and developed RFQ and RFP documents. The overall objective of this effort has been
multifaceted; to reduce transaction costs associated with development and negotiation of RPPA
contracts, to obtain favorable pricing and terms through a large scale regional aggregate
purchase, to rapidly diffuse solar and other renewable technologies, and to enable participation in
RPPA contracts for small governmental entities that would otherwise be unable to participate in
RPPA financing structures due to the size of project sites.
Over 22 jurisdictions in Santa Clara and San Mateo County expressed an interest in
“piggybacking” on the RPPA effort. On February 2, 2010, Cupertino’s Council authorized a
Memorandum of Understanding for Cooperative Purchasing of Power with the County of Santa
Clara, allowing Cupertino’s participation in a County solicitation, a Request for Proposals for a
th
Regional Renewable Power Purchase Agreement (RFP# RRPPA-001-310) issued March 29,
2010. The first Request for Proposals (RFP) issuance included nine participating public
agencies, including the cities of Cupertino, Los Gatos, Milpitas, Morgan Hill, Mountain View,
and Pacifica, along with the County of Santa Clara, the Valley Transit Authority, and the South
Bayside Waste Management Authority.
The initial RFP was to procure a 4MW of renewable power through power purchase agreements.
DOE, Optony (an independent solar consulting firm) and Joint Venture Silicon Valley assisted
the County of Santa Clara, in assembling an evaluation panel consisting of members of the
collaborative. The panel reviewed bid proposals from nine vendors several of which submitted
proposals for more than one bid bundle (grouping of sites for procurement purposes). This
process officially closed on September 8, with the selection of qualified firms for five bundled
project types: large (>650kW/site), medium (160kW – 650kW/site), small (<160kW/site), small
rooftop installations (<220kW/site), and other systems (solar thermal PV, fuel cell, micro-wind
turbine).
Cupertino sites included in this RFP were all for solar canopy/carport parking installations at
City Hall, Quinlan Community Center and the Corporation Yard. Prior to participating in the
RFP, Cupertino worked with City staff, Siemens, and Critigen to evaluate the solar potential of
these sites. A summary of findings are as follows:
Facility Annual kWh Generated Average Annual kWh % Met by System
by PV System Used at Site
City Hall 475,005 524,650 91%
Quinlan 140,564 495,595 28%
Community Center
Corporation Yard 450,503 143,595 314%
Renewable Energy Financing Options
This pilot project considered several available financing structures for renewable energy systems.
Three types of financing are common: owned, leased or Power Purchase Agreement. Each
financing structure has advantages and disadvantages:
1.City-Owned - The City would own the solar power generation system. Advantages include
eligibility for incentive funds and ownership of tradable emission credits. Disadvantages
include significant up front capital costs, annual maintenance expenses for approximately 20
years, and the replacement of inverters between years 10 and 13. Owned systems are
generally considered appropriate for sites where security and access are restricted.
2.Lease-to-buy - Advantages include no up-front capital expenses, and long-term leases that
allow amortization of costs with the potential for ownership. There is a growing market of
lenders and brokers interested in leasing solar installations.
3.Solar Power Purchase Agreements (SPPA) - This option creates a long term agreement for
the purchase of power generated from the solar installation. Typically SPPA's have 20 year
terms with prices determined through negotiations. In the past several years, local
governments throughout California have funded renewable energy projects through lease to
purchase, and Solar Power Purchase Agreements (SPPA). These types of financing structures
provide the opportunity to obtain solar power without the up-front capital investment as the
power generation system is designed and installed by a third party provider and financed
through a third party financier. The governmental entity benefits from capped or slowed
growth in electricity rates, as the normal utility bill is paid to the financier through terms
established in the SPPA. In California, at least ten jurisdictions have issued SPPA’s in the
past two years. These issuances include the California Department of General Services, City
of Fresno, San Francisco Public Utilities Commission, County of Solana, County of San
Diego, and County of Ventura, among others. Project staff reviewed all ten SPPA issuances
to compare terms and conditions.
The SPPA currently being negotiated is working to include a lease-to-buy option.
Project Steps and Status
1.Issue Request for Information - COMPLETE
The purpose of the RFI was to test the assumptions and information gathered to date on different
financing mechanisms and procurement approaches. The RFI required vendors to show their
experience with what financing mechanisms, the extent of that experience, possible terms that
the County could expect, how the market would respond to bundled projects, whether additional
sites should be considered and whether collaborative procurement at scale would deliver
significantly reduced power purchase prices.
Nineteen vendors responded to the RFI. Most firms have experience with a variety of financing
methods. Installed price per kwH power varies as a reflection of the cost of capital, the Federal
tax incentive for private sector investment and state solar incentives, and economies of scale in
supply and financing. The attached RFI Summary Graphs provide general information from the
responses to the RFI. Preliminary observations provided by the County include:
Most respondents indicated that their firm had been in business between 2 and 5 years -The
significance of this finding is that traditional municipal government procurement criteria
require extensive years of experience. Doing so in the renewable energy market would
preclude most firms from competition.
Most respondents are specialized in either solar ground-mount or rooftop systems. A few
firms offer expertise in two or more technology areas, but they tended to be large vendors.
The majority of respondents indicated that the installed cost of power for systems in
general was below $0.19 per kwH. Many firms in lower cost ranges were newer market
entrants.
Most respondents indicated that economies of scale exist in collaborative procurement, and
that these are quantifiable around 5% for bundled project packages of 10 MW, 15 % for
packages of 20 MW, and 20% for packages of 50 MW. These discounts are incorporated to
be compared to the cost per kwH of PG&E rates over the 20 year term of power purchase
agreements.
2.City Signs Memorandum of Understanding – COMPLETE
In order to obtain commitments, County staff requested a Memorandum of Understanding
(MOU) from all jurisdictions. The MOUs were due to the County on February 5, 2010. Staff
th
held a mandatory meeting with City attorneys and staff on December 4, 2009 to review PPA
document terms, the RFP process and other issues. At this meeting 12 jurisdictions indicated that
they wanted to participate in the first RFP issuance. These include; VTA, Morgan Hill, Mountain
View, Cupertino, Sunnyvale, Los Gatos, Milpitas, County of San Mateo, Pacifica, Burlingame,
Foster City and the Silicon Valley Waste Management Authority.. The MOU was finalized
th
through the review of the Board of Supervisors on February 9.
3.Conduct Detailed Solar Site Survey - COMPLETE
Per Section 2.C. of the aforementioned Memorandum of Understanding, to participate in the bundled
PPA project, cities were required to submit proposed real property sites that may accommodate
renewable energy installations (individually, a “Site Survey”, and collectively the “Site
Surveys”) prepared by a licensed engineer in a uniform, industry standard format. To achieve
this requirement, the city joined neighboring jurisdictions to work with CH2M Hill (now Critigen,
LLC) to conduct solar site surveys by piggyback upon the competitively bid contract won by the
company to analyze Santa Clara County-owned assets.
The survey was solar site analysis and electrical and structural analysis. The city completed this
process with three sites and abutting parking lots, Community Hall, Quinlan Community Center and
the Corporation Yard. Work concluded in June and the results of the study are included in
Comment \[EC1\]: EC to add.

4.Issue Request for Proposal (RFP) for Power Purchase Agreements COMPLETE
The Request for Proposals to procure an initial 4MW of renewable power for county sites
th
through power purchase agreements was issued on March 29 through BidSync. This
th
Solicitation was managed in two steps: Step 1 – Pre-Qualification due by 3PM on May 7, 2010
and Step 2 – Final Selection for Renewable Power Generating (RPG) Systems Bundles due by
3PM on June 29, 2010.
5.Evaluate Vendor Proposals COMPLETE
The proposals for seven qualified firms were reviewed between the RFP deadline by the
project’s leadership team which included the following members:
Siva Darbhamulla, Chief of Design Services, County of Santa Clara
Ben Foster, Vice President, Optony
Caroline Judy, Assistant Director, Government Support Services, County of Alameda
Jerry Lahr, Power Program Manager, Association of Bay Area Governments
Kara Gross, Vice President, Joint Venture: Silicon Valley Network
Rachel Massaro, Associate Director of Climate Initiatives, Joint Venture: Silicon Valley
Network
Steve Mitra, County Counsel, County of Santa Clara
Lin Ortega, Utilities Engineer/Program Manager, County of Santa Clara
Chris Schroeder, Purchasing Agent, City of Milpitas
, Energy Program Manager, City of San Jose
Mary Tucker
The RFP evaluation criteria is provided on pages 27 – 29 in the RFP document, but focus
primarily within four categories: firm and team qualifications, relevant project experience,
technical expertise and proposed system cost. Using these factors, the Evaluation Committee
determined the responsiveness and best value quality of the proposal. Using this criteria the
following firms were selected for the following bundles:
Large – >650kW/site
Medium – 160kW – 650kW/site
Small – <160kW/site
Small Rooftop – <220kW/site
Other - solar thermal PV, fuel cell, micro-wind turbine
Relevant to Cupertino, the evaluation team selected Borrego Solar Systems, Inc.
) to contract with cities to site medium sized bundles and Ecoplexus
(www.borregosolar.com
) to develop the City’s small sites.

6.Negotiate Final Contract Initiated: November 2010
Over the course of the month of October, legal and environmental representatives from each
participating agency have participated in a series of joint contract negotiations with SPPA
vendors. The coordinating committee convened this process to save both staff time and leverage
the collective bargaining power of representative public agencies. Staff met in advance of
initiating the vendor negotiation to discuss each agency’s key contracting requirements and
establish a strategy to ensure all parties achieved mutually beneficial joint outcomes from the
process. Vendor negotiations are scheduled to continue through November 10.
7.Prepare for and Complete Construction Anticipated: December 2010 – December 2011
The consulting firm, Optony, which has been assisting the County and partner agencies in the
solar renewable energy procurement project to date, will be retained throughout the design,
engineering and construction phases of the project. In this role, Optony will ensure that the
renewable energy system is (1) optimized through the review of system drawings and plans, is
(2) constructed using the same components required through the contract, (3) meets industry
standards for installation and production, and is (4) properly maintained to achieve all applicable
warrantees. In partnership with staff, Optony will also work with Pacific Gas and Electric to
develop an interconnection plan and verify that all California Solar Initiative (CSI) milestones
are being met with rebates and deposits transferred back to the City. Furthermore, supporting
staff will work with the vendor to ensure that parking lot closures are minimized during the
construction phase and that vendor strictly adheres to the arborist’s tree mitigation plan and
procedures.
8.Monitor and report on system production ONGOING
The RFP clearly states that the firm must also provide for real-time monitoring and verification
of power generated at each site listed during commercial operation. To achieve this requirement,
the SPPA builds in a series of activities including the installation and maintenance of a meter at
the delivery point and a monitoring system for each generating facility. Meters and all metering
activities are to be provided, installed, owned and maintained, programmed and operated at the
vendor’s expense and in compliance with of all applicable Transmission Provider Tariffs and the
Buyer-PG&E Interconnection Agreement. The aforementioned monitoring system may be
provided as a web-based tool or interface to view, collect and store data, in real time, including
the energy delivered, greenhouse gas emissions reduced, AC efficiency, peak DC efficiency and
total percent of energy used from the system.

systems, including financing, installation, maintenance, and operation.
Support the creation of local clean tech jobs.
Fiscal Impact
Full cost recovery is anticipated.
Recommended Action
Receive report and provide direction to staff.
If Council should direct staff to proceed, staff will take the final enabling actions to advance the
project scope:
th
Project Due Diligence – Anticipated November 16
o Complete arborist report for two sites with tree considerations (Civic Center and
Quinlan Community Center)
o Complete joint contract negotiations to finalize Solar Power Purchase Agreement
(contract) with vendors
o Return for Council approval of the Solar Power Purchase Agreement
nd
Design Review Committee – Anticipated December 2
o Complete Community Development Department Pre-Application Form and submit
associated fees
o Develop and submit Design Review Committee staff report required to obtain (1)
CEQA determination (2) architectural and site approval and (3) tree removal permits
o Notice the public and host Design Review Committee Public Hearing
th
CEQA Compliance – Anticipated December 17
o Mail Categorical Exemption Notice to County of Santa Clara
o Design Review Committee and County’s appeal/comment period ends
o Submit building permit and associated fees
o Staff engaged two independent consultants to assess the project proposal under
CEQA. In both cases, the consultants confirmed that the solar carport system would
be categorically exempt under section 15303. Section 15303(e) consists of
construction and location of limited numbers of small new equipment or structures
and specifically identifies carports within its provisions. This is consistent with the
findings of the California Energy Commission report titled “Distributed Generation:
CEQA Review and Permit Streamlining,” which notes that under 15303 “certain
types of DG may qualify if they have small footprints and the site’s zoning allows
power generation to occur there.”
