What PG&E Is Offering
PG&E is the administrator of several distributed generation technologies and programs including:

The California Solar Initiative (CSI) program makes powering homes and businesses with clean, renewable solar energy easier than ever before by providing a financial incentive for installing qualifying photovoltaic systems.

PG&E is a proud program administrator of the CSI program and is ready to help our customers go solar today. We've already assisted over 50,000 customers with their installations, more than any other utility in the United States, and we're looking forward to helping more customers become the next Californians to make a difference.

Program Eligibility
To qualify for the California Solar Initiative (CSI), all program eligibility requirements must be met. This includes the following:

  • Project site must be in the service territory of PG&E and receive retail electric service.
  • If it is a residential project, it must be retrofit (existing) or if it’s a non-residential project, (Commercial, Industrial, Agricultural, Public Entity and Government) it can be retrofit (existing) or new construction.
    NOTE: Due to budgetary constraints, CSI funding for non-residential solar incentives has been depleted as of December 23, 2010. PG&E may be unable to guarantee a CSI incentive for unreserved non-residential applications received on or after December 24, 2010. Please continue to submit your reservation requests and PG&E will include your application on the CSI Non-Residential project wait list based on the time and date it was received. Waitlisted projects will be processed on a first come, first served basis if and when funding becomes available.

    Learn more about how to be added to the CSI wait list.
  • Must use new equipment that has been approved by the California Energy Commission (CEC).
  • Please visit the most recent CSI Program Handbook for complete program guidelines and use it as a general reference for all CSI program questions.
The CSI incentives differ by customer segment and system size, and are intended to encourage high performing systems. Learn more about the CSI program.

The Multifamily Affordable Solar Housing (MASH) program provides higher incentives to offset the project costs of installing solar on multifamily affordable housing buildings in California. The goal of the MASH program is to incorporate high levels of energy efficiency and high performing solar systems to help enhance the overall quality of affordable housing.
The New Solar Homes Partnership (NSHP) is part of the comprehensive statewide solar program, known as the California Solar Initiative. The NSHP provides financial incentives and other support to home builders, encouraging the construction of new, energy efficient solar homes.
PG&E is now offering incentives to customers who are investing in solar water heating systems. Approved by the California Public Utilities Commission (CPUC) in January, 2010, the California Solar Initiative (CSI–Thermal) program provides rebates to residential and non-residential customers who install eligible solar water heating systems in their home or business.

Program Overview and Background
Through the signing of California Assembly Bill (AB) 1470 for gas service, and California Senate Bill (SB) 1 for electricity service, the CSI–Thermal program provides incentives to eligible customers who are installing solar water heating systems.

The CSI–Thermal program is administered by PG&E, Southern California Edison (SCE), Southern California Gas (SoCalGas) and the California Center for Sustainable Energy (CCSE) in San Diego Gas and Electric (SDG&E) service territory. Program administrators began accepting single-family residential applications in May 2010, and multifamily and commercial applications in October, 2010. The program will run for eight years, ending on December 31, 2017 or until the incentive budget allocations are exhausted, which ever comes first.

AB 1470 also set aside a portion of the gas budget to provide incentives for a low-income program that will be adopted by a separate decision at a later date.

Customer Eligibility
To qualify for the CSI-Thermal program, customers must heat their water with gas or electricity provided by PG&E, San Diego Gas and Electric (SDG&E), Southern California Edison (SCE) or Southern California Gas (SoCalGas). Complete program guidelines can be found in the CSI-Thermal Program Handbook.

CSI-Thermal incentives are based on an expected annual energy displacement. Incentive amounts differ based on customers' system type, class (e.g., residential or commercial) and solar water heating fuel source (e.g., gas or electric). Learn more about the incentive structure.

How to Apply
The CSI–Thermal program has established an application process which will differ based on customers' system size, customer class (e.g., residential or commercial) and solar water heating fuel source (e.g., gas or electric). Learn more about the application process and the required documentation.

Frequently Asked Questions (FAQ)
Please visit our Frequently Asked Questions section for more information on the CSI-Thermal program.

Small wind turbines are small, electricity-producing, wind-driven generating systems with a rated output of 50 kilowatts or less.

While residential customers are not excluded from the program, the minimum 30 kilowatt system size for renewable technologies generally limits most applications to non-residential energy consumers. To learn more about rebates for wind or fuel cell systems that generate less than 30 kW of energy, please visit the California Energy Commission's Emerging Renewables program or to learn more about Emerging Renewables Program Rebates.

The Self Generation Incentive Program (SGIP) provides financial incentives for the installation of new, qualifying wind or fuel cell self-generation equipment.
