To comply with Washington state law (RCW 19.29A), Peninsula Light is required to report its annual fuel mixture information by generation category. This report, filed with the Department of Commerce reflects the previous calendar year’s fuel mix. We are happy to tell you that nearly all of the electricity provided to Peninsula Light members in 2017 was certified as carbon-free.
For 2017, the report shows that about 83 percent of PenLight’s wholesale electricity purchases from the Bonneville Power Administration came from hydropower. Wind power, a qualifying renewable energy source under the Washington State Energy Independence Act (I-937), represents 7 percent of the fuel mix, and 8 percent of our fuel comes from the Columbia Generating Station—a nuclear power plant in south-central Washington. Only 2 percent of our power comes from fossil fuels, with 1 percent each from coal and natural gas. For more information, visit the Power Resources section of our website.
