HomeMy WebLinkAboutMINUTES - 07102012 - C.91RECOMMENDATION(S):
APPROVE and AUTHORIZE the Public Works Director, or designee, to execute the above contract amendment with
Main Street Power (MSP), which would adjust the power output and project schedule for the solar panel system being
installed for the County at the West County Detention Center (WCDC) site in Richmond.
FISCAL IMPACT:
Under its contracts with the County, MSP is paying the entire cost to acquire, construct, and maintain the solar panel
system on the County facilities, including the WCDC site. With re-design of the system required for the WCDC site
and engineering adjustments for other sites, the total estimated electricity cost savings to the County over the 20-year
term of the contracts would decrease from approximately $516,000 to $96,182. However, the County would not be
required to pay for the re-design, any additional construction costs incurred by MSP, or the decrease in power sale
revenues.

Subject:Second Amendment to Contra Costa County Power Purchase Agreement (Non-New Markets Tax Credit Project Sites)
with Main Street Power
BACKGROUND:
On September 28, 2010, the Board approved and authorized the execution of two Power Purchase Agreements with
Main Street Power (MSP)—one for nine Non-New Markets Tax Credit sites and the other for three New Markets
Tax Credit sites. Under its contracts with the County, MSP, at its expense, has completed installation of the solar
panel system at eleven of the twelve County-owned sites. Solar power is now being supplied to the County at those
eleven sites.
On September 11, 2011, to make way for installation of a ground-mounted solar panel array at the twelfth site—the
West County Detention Center (WCDC) site—MSP’s contractor cut eucalyptus trees in an area near the entrance to
the East Bay Regional Park District Point Pinole Regional Shoreline. Since that time, Public Works staff has been
working with MSP and the community to come up with a re-design of the solar panel system at the WCDC that is
more environmentally sensitive. On June 26, 2012, the Board approved a re-designed project consisting of a carport
system at the WCDC parking lot in place of the original ground-mounted system and approved a Negative
Declaration pursuant to the California Environmental Quality Act (CEQA) to allow the re-designed project to move
forward.
With the re-design of the system at the WCDC site, the solar panels at that site will be smaller in size and will
consequently produce less electricity (solar power). According to MSP’s calculations, which have been checked by
County staff, annual power production at the WCDC site would decrease from 1,592,924 to 1,211,751 kWh—a
decrease of 381,173 kWh for the WCDC site. In addition, when the solar power system was installed at the eleven
other County sites, field engineering adjustments were made at five sites that also resulted in a decrease in annual
power production from 2,277,182 to 1,853,165 kWh—a decrease of 424,017 kWh for those sites.
When the MSP contracts were approved by the Board in September 2010, it was estimated that the contracts would
give the County approximately $516,000 in electricity cost savings over the 20-year term of the contracts and would
replace standard PG&E power with more environmentally sensitive solar power. With the 805,190 kWh decrease in
estimated power production at the WCDC site and the other five sites, it is now estimated that the County’s electricity
cost savings over the 20-year term would be $96,182.
Under MSP’s contracts with the County, MSP guarantees delivery of at least 80% of the solar power output listed for
each of the twelve County-owned sites. An administrative amendment previously signed by the Public Works
Director has already revised the power output figures listed in the contracts to reflect the field engineering
adjustments made at five of the completed sites. MSP has now proposed a second amendment to the contract for the
Non-New Markets Tax Credit sites, including the WCDC site, to formally reflect the reduced solar power output at
the nine sites covered by that contract and the revised construction schedule for completion of the re-designed system
at the WCDC site.
Public Works staff recommends that the Board approve the second amendment to the contract for the nine Non-New
Markets Tax Credits sites and authorize the Public Works Director, or designee, to sign the amendment for the
County. Recently, MSP has claimed substantial extra expenses incurred for the system re-design at the WCDC site,
for construction of the re-designed system at the WCDC site, and for the decrease in power sale revenues at the
WCDC site. However, MSP has now given assurances that the proposed amendment would resolve those claims at
no expense to the County, and the Board’s approval would be contingent on that basis. Under the arrangement with
MSP, the County would be responsible for the cost of replanting trees and other landscaping to replace the eucalyptus
trees cut by MSP’s contractor in September 2011.
CONSEQUENCE OF NEGATIVE ACTION:
The amendment will not be executed to revise the contract for the Non-New Markets Tax Credit sites.
CHILDREN'S IMPACT STATEMENT:
None.
