Existing law vests the Public Utilities Commission with regulatory authority over public utilities, including electrical corporations. Under existing law, the commission administers, or otherwise oversees, various public purpose programs, including energy efficiency and conservation programs, cost-effective energy efficiency programs, the Family Electric Rate Assistance program, the California Alternate Rates for Energy program, rate assistance programs for eligible food banks, and home insulation financial assistance programs. Under existing law, those programs are generally funded through a charge on electrical service, which is collected through customer rates.
