PenLight’s Electricity is 95% Carbon-Free

To comply with Washington state law (RCW 19.29A), Peninsula Light is required to report its annual fuel mix by generation category. This report, filed with the Department of Commerce, reflects the previous calendar year's fuel mix. We are proud to tell you that nearly all of the electricity provided to Peninsula Light members in 2019 was certified as carbon-free.

For 2019, the report shows 76% of PenLight’s wholesale electricity purchases from the Bonneville Power Administration came from hydropower. We are fortunate in the Northwest to have abundant hydro resources to generate electricity. Hydropower produces zero carbon emissions, helping us provide clean energy to homes and businesses.

PenLight also buys renewable energy credits from wind resources, a qualifying renewable energy source as required under the Washington State Energy Independence Act (Initiative 937). It represents 9% of the fuel mix. About 10% of our power comes from the Columbia Generating Station—a nuclear power plant in south-central Washington.

According to the report, less than 5% of our power comes from unspecified sources, which are market purchases made by BPA to serve its customers’ energy needs.
