Trade-offs pending in PGE, BPA transmission project

Trade-offs pending in PGE, BPA transmission project


Portland General Electric (PGE) and the Bonneville Power Administration (BPA) have signed a Memorandum of Understanding to negotiate a modification to PGE's proposed 215-mile Cascade Crossing Transmission Project which was intended to meet PGE's customers' growing energy needs, enhance the region's grid, and support development of wind generation projects east of the Cascades

The modification would eliminate about 101 miles of the project to avoid some impacts to the Confederated Tribes of Warm Springs Reservation, the Mt. Hood and Willamette national forests, and private forest and agricultural land.

Also in the modification, PGE would invest in grid enhancements and/or exchange assets with BPA to increase transmission capacity, and potentially reduce congestion and enhance reliability of the grid. In return, PGE could receive up to 2,600 MW of transmission capacity ownership rights to deliver electricity to customers in Portland and the Willamette Valley.

"PGE and BPA have been working collaboratively using a 'one-utility' approach to identify opportunities to leverage both utilities' current and future transmission assets," said PGE Senior Vice President of Customer Service, Transmission and Distribution Bill Nicholson. "This solution should reduce the impacts of new transmission, manage costs and benefit customers of both utilities."

Specific contract terms are still being discussed, and must still undergo stakeholder and environmental review processes.
