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 2021, the PCL for 2020 was released. It shows AMP’s 100% clean portfolio effective January 1, 2020.
100% Clean Energy
On Jan. 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 resources, so AMP added geothermal to its energy supply, followed by wind, landfill gas and hydropower over the next several decades.
By 2011, AMP easily exceeded the state’s Renewable Portfolio Standard (RPS), which requires electric utilities to purchase a growing percentage of their electricity from renewable sources by 2030.
AMP developed so much renewable energy that it was able to strategically sell portions of it on a short-term basis to other utilities struggling to meet the RPS mandate. At the direction of the city of Alameda’s Public Utilities Board, funds from the short-term sales must be used for local investments in programs that reduce greenhouse gas emissions associated with electricity use.
AMP’s short-term sales of renewable energy ended in 2019, making Alameda’s energy supply 100% clean as of January 1, 2020. AMP will meet Alameda’s energy needs with 100% clean energy for years to come.
Power Mix Sources in 2020
AMP’s most recent PCL covers the 2020 calendar year. During 2020, 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 2020 power mix included:
- Biomass (landfill gas) from Pittsburg, Butte County, Santa Cruz and Half Moon Bay
- Small hydroelectric from Graeagle and New Spicer Meadows
- Winds from the High Winds Project in Solano County
Large hydroelectric projects in Calaveras and the Central Valley contributed 26.9% of AMP's 2020 energy mix. While large hydroelectric sources produce clean energy, California does not count power from large hydroelectric dams as eligible renewable.
* "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 RPS. The eligible renewable percentage shown in the chart below does not reflect RPS compliance, which is determined using a different methodology.
The CEC's 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.
If you are a participant in Alameda Green, Alameda Municipal Power purchased unbundled RECs to match all or a portion of your energy usage.
The column labeled "standard" reflects AMP's energy mix.

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.
