Center for Sustainable Energy

CSE administers the California Solar Initiative-Thermal (CSI-T) Program for customers in the San Diego Gas & Electric (SDG&E) territory. Through the $28 million incentive program, homeowners, multifamily and commercial property owners, and governmental organizations can generate significant savings through rebates by installing solar water heating systems for pools and buildings that displace natural gas usage and reduce greenhouse gas emissions.

The CSI-T Program is a ratepayer-funded rebate program for customers of the four California investor-owned utilities. Rebates for solar water heating systems are based on the amount of  energy the system is expected to displace in one year.
