The Bonneville Power Administration (BPA) has proposed 13 new transmission projects to expand the Pacific Northwest's grid infrastructure. Combined, the projects are estimated to cost approximately $3 billion. Each project must undergo preliminary engineering and environmental review to inform a final construction decision.
“With historic levels of high demand growth projected across the region in the years to come, the 13 transmission projects being announced today by BPA represent a big step forward on system capacity and reliability," said DOE infrastructure undersecretary David Crane. "The result should be a lasting benefit to BPA’s customers and to the energy consumers of the Pacific Northwest more generally."
This comes after BPA's announcement of 10 other projects in July 2023. Following this announcement, the overall transmission upgrade cost is estimated at $5 billion. In addition, for the financial year 2025, BPA has approved a budget of $590 million for grid reinforcements to maintain reliability and preserve existing transmission lines, substations, and other equipment.
