Cal. PUC § 379.10

(a) In administering the self-generation incentive program pursuant to Section 379.6, the commission shall use funds appropriated by the Legislature for the purpose of providing incentives to eligible low-income residential customers, including those receiving service from a local publicly owned electric utility, as defined pursuant to Section 224.3, who install behind-the-meter energy storage systems or solar photovoltaic systems paired with energy storage systems, as an integrated approach to increase individual customer resiliency, to reduce the electrical grid’s net peak demand, to reduce electric ratepayer costs, and to reduce emissions of greenhouse gases and localized air pollution.

(b) The commission shall consider requiring customers installing solar photovoltaic systems paired with energy storage systems or new energy storage systems under this section and served on a standard contract or tariff pursuant Section 2827.1 to participate in a demand response or peak load reduction program offered through the customer’s load-serving entity, including market-integrated supply-side demand response programs, to reduce net peak demand.
