The Bonneville Power Administration (BPA) has identified 13 new transmission substation and line projects designed to reinforce the Pacific Northwest’s electric grid. If constructed, these projects would accommodate regional load growth and enable the BPA to add thousands of megawatts of new wind and solar generation, and battery storage to the federal grid. Combined, the projects are estimated to cost approximately $3 billion. The projects would add to a list of other projects the BPA announced in July 2023, bringing the total to more than 20 with an estimated cost of approximately $5 billion. “BPA continues to answer the call to meet the region’s transmission needs driven by electrification, clean energy goals, and growing energy demand,” John Hairston, administrator and CEO of the BPA, said in a statement. “Consistent, steady energy infrastructure investments such as these will help the region maintain reliability and a strong economy fueled by clean energy. This work would not be possible without the $10 billion increase in Treasury borrowing authority championed by the Northwest Congressional delegation.” Congress included the $10 billion increase Hairston mentioned in the 2021 Infrastructure Investment and Jobs Act, raising the BPA’s borrowing authority with the U.S. Treasury to $17.7 billion. The BPA said borrowing authority works like a revolving line of credit and is the agency’s primary source of debt financing for capital investments, including transmission.
