WORKSHOP
To: Board of Directors
From: Kathleen Neus
Date: April 15, 2009
Subject: SB1 Solar Program Update
1. WHY THIS MATTER IS BEFORE THE BOARD
This workshop item is a review of the District's Solar Program (SB-1).
2. HISTORY
As part of the State's Million Solar Roof Program, publicly owned electric utilities must
adopt, implement and finance a solar initiative program by January 1, 2008. SB-1
imposes a state mandated local program that requires the District to make program
information available to its customers. In addition, SB-1 establishes specific
requirements for local programs, including system incentives and a minimum rebate
amount.
The District must use rate payer funds and expend $1,773,408 over ten years. The
dollar amount was set by the California State Legislature and is based upon the
District's percentage of the total statewide load served by all local publicly owned
electric utilities within California.
The District hired Efficiency Services Group in June 2007 to help the District to
prepare and implement the District's Solar Program as required by SB-1. The Board
approved the District's SB-1 program on November 19, 2007.
3. NEW INFORMATION
At the end of 2008, the Federal Government extended the tax credit for eight years
and increased the tax credit from $2000 to 30% of the cost of the project. Due to the
tax extension and the increased dollar amount, many applicants have asked to be
moved into 2009 or 2010.
As of April 1, 2009 there has been a total of 12 installations, 2 commercial and 10
residential applications; for a total of 43.6 kW of installed solar generation. Total
dollar amount rebated to date is $169,094.
The Truckee Sanitary District's project is expected to be built over the summer. The
expected installed generation is in 100 - 110 kW range.
Today the queue for 2009 is 10 applications; with a potential rebate dollars of
$171,500. Resulting in an estimated capacity of 43 kW.
2010 queue has 11 applicants, $178,200 rebate dollars, 52 kW expected to be
installed, which includes three commercial applications.
Attached to this document are the following items:
1) Chart showing Projected PV Capacity through 2010;
2) Summary of NCPA Members Solar Rebate Amounts; and
3) NCPA Members PV System Summary for 2008 and 2009.
4. FISCAL IMPACT
The Board approved a customer charge to fund the District's Solar Program. The
customer charge to raise $177, 400 annually is as follows:
Residential $0.60 per month
Small Commercial $5.00 per month
Medium Commercial $10.00 per month
Large Commercial $15.00 per month
