During 2010‒20, CSE administered the California Solar Initiative‒Thermal (CSI‒T) Program for residential and commercial utility customers in the San Diego Gas & Electric (SDG&E) territory for the California Public Utilities Commission. The program provided significant rebates for water heating systems installed in buildings and swimming pools to displace natural gas and electricity use and reduce greenhouse gas emissions.

Through the program, CSE awarded more than 530 rebates totaling over $10 million to homeowners, multifamily and commercial property owners and governmental organizations for systems that lowered their energy costs, reduced their reliance on fossil fuels and created a more sustainable energy future in the San Diego region. We also offered educational programs and workshops, professional training and other activities aimed at promoting the widespread adoption of solar water heating and the growth of a strong solar industry.

Today, CSE draws upon the expertise and experience we gained as CSI-T program managers to assist consumers and governments nationwide through many clean energy programs.
