Getting to 100% renewable energy by 2025

Our power resources team procures 100% carbon-free energy that is 50% renewable for our ECOplus service and 100% renewable for ECO100. Our goal is to deliver 100% renewable energy to match demand on an hour-by-hour basis by 2025. To learn more, download our whitepaper, “Our path to 24/7 renewable energy by 2025.”

1 The eligible renewable percentage above does not reflect RPS compliance, which is determined using a different methodology.
2 Unspecified power is electricity that has been purchased through open market transactions and is not traceable to a specific generation source.
3 Renewable energy credits (RECs) are tracking instruments issued for renewable generation. Unbundled renewable energy credits (RECs) represent renewable generation that was not delivered to serve retail sales. Unbundled RECs are not reflected in the power mix or GHG emissions intensities above.

1 Percentages are estimated annually by the California Energy Commission based on the electricity sold to California consumers during the identified year.
2 The eligible renewable percentage above does not reflect RPS compliance, which is determined using a different methodology.
3 “Unspecified sources” of power refers to electricity that is not traceable to a specific generating facility, such as electricity traded through open market transactions. Unspecified sources of power are typically a mix of all resource types, and may include renewables.
