The Washington Utilities Commission on June 28 approved Puget Sound Energy Inc.’s solicitation process for demand response, as well as other resources including electric generation sources, energy storage, and renewable energy credits. The company’s resource acquisition process follows its integrated resource planning analysis, which establishes capacity and renewable energy needs on a biennial basis. The resource plan forecasts a modest capacity need until 2021, but grows to 272 megawatts in 2022 following the retirement of two units of the Colstrip plant. The plan seeks to have enough resources to meet 671,000 renewable energy credits from 2023. Puget Sound is a subsidiary of Puget Energy Inc.
