Getting to 100% renewable energy by 2025

Our power resources team procures 100% clean energy that is at least 50% renewable for our ECOplus service and 100% renewable for ECO100. Our goal is to deliver 100% renewable energy by 2025 and on a 99% time-coincident basis by 2027. To learn more, download our whitepaper, “Our path to 24/7 renewable energy by 2025.”

Emissions factor

Since launching in 2016, Peninsula Clean Energy has been providing cleaner electricity. The graph shows our emissions factor for each year.

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.
