Power Content Label
The Power Content Label (PCL) is an annual report that shows where your electricity was generated during the calendar year and how it compares to the State of California's power mix. The PCL is released each fall for the prior calendar year. In fall 2025, the PCL for 2024 was released. It shows AMP's 100% clean portfolio that began January 1, 2020 and continued through 2024.
100% Clean Energy
On January 1, 2020, AMP began providing 100% clean energy to all customers. AMP reached this clean energy milestone decades ahead of California's goal of 100% clean power by 2045. AMP has been a leader in the promotion of clean power since the 1980s. Residents and businesses wanted their power to come from renewable sources, so AMP added geothermal to its energy supply, followed by wind, landfill, gas, and hydropower over the next several decades.
Power Mix Sources in 2024
AMP's most recent PCL covers the 2024 calendar year. During 2024, 100% of AMP's power mix came from clean energy sources, including Eligible Renewable* sources and large hydroelectric sources. Eligible Renewable sources in AMP's 2024 power mix included:
- Geothermal from the NCPA Geothermal Project at the Geysers
- Biomass (landfill gas) from Pittsburg, Butte County, Santa Cruz and Half Moon Bay
- Small hydroelectric from Graeagle and New Spicer Meadows
- Wind from the High Winds Project in Solano County
* Eligible Renewable sources are energy resources that either cannot be used up or are quickly replenished through natural processes. In California, biomass and waste, geothermal, solar, small hydroelectric, and wind energy resources are all considered eligible renewable resources under the Renewables Portfolio Standard (RPS). The eligible renewable percentage shown in the chart below does not reflect RPS compliance, which is determined using a different methodology.
Large hydroelectric projects in Calaveras and the Central Valley contributed 31% of AMP's 2024 energy mix. While large hydroelectric sources produce clean energy, California does not consider power from large hydroelectric dams as Eligible Renewable.
AMP's resources had a GHG emissions intensity of 1lb carbon dioxide equivalent (CO₂e)/megawatt hour (MWh) as compared to the state's 2024 average emissions factor of 359lbs CO₂e/MWh. AMP's emissions come from renewable geothermal and landfill resources. Geothermal resources are associated with a small amount of fugitive CO₂ emissions released from underground geologic formations. Renewable landfill gas emissions from the naturally occurring decomposition of organic waste materials are not counted towards AMP's emissions intensity, but small amounts of fugitive methane (CH4) emissions and nitrous oxide (N₂O) emissions resulting from the combustion of landfill gas are captured in AMP's emissions intensity.
The California Energy Commission's (CEC) PCL calculation is a snapshot of one year's resources, whereas California's RPS compliance reporting looks at several years at a time, with a focus on rewarding long-term investments in renewables.
