The California Solar Initiative (CSI) is overseen by the California Public Utilities Commission (CPUC) and provides incentives for solar system installations to customers of the state's three investor-owned utilities (IOUs): Pacific Gas and Electric Company (PG&E), Southern California Edison (SCE) and San Diego Gas and Electric (SDG&E). The CSI Program provides upfront incentives for solar systems installed on existing residential homes, as well as existing and new commercial, industrial, government, non-profit, and agricultural properties within the service territories of the IOUs.
The CSI Program expanded state support for solar technology and is the product of Governor Schwarzenegger's "Million Solar Roofs" vision for the State of California. The CSI Program was authorized by the CPUC through a number of regulatory decisions throughout 2006. In addition, the legislature expressly authorized the CPUC to create the California Solar Initiative in 2006 in Senate Bill 1 (Murray). When it launched in January 2007, the CSI Program built upon nearly 10 years of state support for solar, including other incentive programs such as the Emerging Renewables Program (ERP) and the Self-Generation Incentive Program (SGIP). Both programs still exist to provide incentives for other technologies but have been closed to new solar projects as of the end of 2006.
CSI Program Components
The CSI Program has a budget of $2.167 billion over 10 years, and the goal is to reach 1,940 MW of installed solar capacity by the end of 2016. The goal includes 1,750 MW of capacity from the general market program, as well as 190 MW of capacity from the low income programs. The general market program is the main incentive program component of the CSI, and is administered through three Program Administrators: PG&E, SCE, and California Center for Sustainable Energy (CCSE) in SDG&E territory.
In addition to the general market program, the CSI Program has four other program components, each with their own program administrator and 10 year budgets:
- A research and development (RD&D) program, providing grants to solar technologies that can advance the overall goals of the CSI Program; the RD&D program is administered through the RD&D Program Manager, Itron, and has a budget of $50 million.
- The Single-family Solar Affordable Solar Housing (SASH) program, providing solar incentives to single family low income housing; the SASH program is administered through the SASH Program Manager, GRID Alternatives, and has a budget of $108 million.
- The Multifamily Affordable Solar Housing (MASH) program, providing solar incentives to multifamily low income housing; the MASH program is administered through the same Program Administrators as the general market program: PG&E, SCE, and CCSE, and it has a budget of $108 million.
- The Solar Water Heating Pilot Program (SWHPP), providing solar hot water incentives to residences and businesses in San Diego only; the SWHPP is administered through CCSE.
In addition to the CPUC's CSI Program, Senate Bill 1 envisioned that
the State of California would also have other programs to support
onsite solar projects, including the California Energy Commission's New
Solar Homes Partnership (NSHP), and a variety of solar programs offered
through publicly owned utilities (POU). The statewide effort includes
the CSI - as well as the NSHP and the POU programs - and it is known
collectively as Go Solar California. The statewide goal of the Go Solar
California campaign is 3,000 MW and there is a statewide budget of $3.3
billion.
The CSI Program is a subset of the wider solar effort in California.
