The Pacific Northwest Electric Power Planning and Conservation Act (better known as the Northwest Power Act) turned 40 years old in December. Richard Devlin, chair of the Northwest Power and Conservation Council created by the act, recently joined NewsData Publisher/Editor-in-Chief Mark Ohrenschall in the latest episode of Substation Northwest podcast to explore the origins of this landmark federal legislation, its legacies in regional power and fish/wildlife mitigation, the Council's role and evolution as a regionwide planning body, and what the next 40 years may bring for this "very successful" and "quite unique" Northwest institution.
