California Distributed Generation Statistics (California DG Stats) currently includes data for all solar photovoltaic (PV) systems interconnected through the California Investor Owned Utilities (IOUs) net energy metering (NEM) tariffs. California IOUs include Pacific Gas & Electric (PG&E), Southern California Edison (SCE) and San Diego Gas & Electric (SDG&E). Publicly owned utility (POU) interconnection solar PV NEM data is not available. However, POUs annually report their cumulative incentivized capacity to the California Energy Commission per Senate Bill 1. These values are only added into the “CA Leads the Nation” numbers on the homepage and updated annually. See See here
for more information about POU solar PV data.
California DG Stats does not currently include any other interconnection data from other
technologies such as wind, fuel cells, biomass, etc. However, non-solar PV projects which received an
incentive from the Self-Generation Incentive Program (SGIP) can be downloaded here
California DG Stats also makes available various incentive program data sets. For
