US-based Seattle City Light (SCL) has selected GE Renewable Energy to rebuild three generators in the 1,117MW Boundary Dam powerhouse.
The project is expected to further improve generator output performance by +12%, as well as enhance the grid stability.
Located on the Pend Oreille River in Northeastern Washington State, Boundary Dam supplies up to 30% of SCL’s annual energy needs.
Under the contract, GE Renewable Energy will rebuild powerhouse generators 51, 52, and 54 (3 x 145 MVA) and will also be responsible for engineering and site work.
The rehabilitation is expected to allow safe operation for the next four decades.
GE Renewable Energy North America Hydro business general manager Pierre Marx said: “We appreciate the confidence that Seattle City Light & Eugene Water & Electric Board has shown in GE Renewable Energy.
“Our teams in Brossard, Canada and Denver, Colorado, are working closely with our customers to deliver the best outcomes to them.
“It is more important than ever to keep the US hydro fleet operating at full capacity given its critical role in maintaining stable and efficient electric service while enabling the addition of other renewable power sources like wind and solar.”
GE Renewable Energy’s teams intend to begin onsite work on the generators covered in this project in July next year, with completion expected by May 2022.
Seattle City Light Power Supply officer Mike Haynes said: “Seattle City Light is pleased with the outcome of this solicitation and looks forward to a strong relationship with GE as we continue to enhance our renewable energy portfolio for our customers.”
