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, which means that the 2019 PCL will be released in fall 2020. The fall 2020 PCL, to be released in fall 2021, will show AMP’s 100% clean portfolio effective January 1, 2020.

100% Clean Energy in 2020

On Jan. 1, 2020, AMP began providing 100% clean energy to all customers. AMP has 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 2018

AMP’s most recent PCL covers the 2018 calendar year. During 2018, 53% of AMP’s power mix came from clean energy sources, including eligible renewable sources* and large hydroelectric sources. Twenty-one percent of AMP’s power mix came from eligible renewable resources, including:

  • Biomass (landfill gas) from Pittsburg, Butte, Santa Cruz and Richmond
  • Small hydroelectric from Graeagle
  • Winds from the High Winds Project in Sonoma County

An additional 45 percent of our power mix came from large hydroelectric projects in Calaveras and the Central Valley. 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 California’s Renewables Portfolio Standard (RPS.) 

Please note: The CEC’s PCL calculation is not directly linked to California’s RPS compliance calculation. The PCL is a snapshot of one year’s resources, whereas RPS compliance reporting looks at several years at a time, with a focus on rewarding long-term investments in renewables.
