GE Renewable Energy to rebuild generators at Boundary plant

28 June 2018

The hydropower business of GE Renewable Energy has been chosen by Seattle City Light (SCL), to rebuild three generators in the powerhouse of the Boundary Dam, inproving output performance by +12% and enhancing grid stability.

The Boundary Dam is located on the Pend Oreille River in Northeastern Washington State and supplies up to 30% of SCL's annual energy needs.

The project includes refurbishment of powerhouse generators 51, 52, and 54 (3 x 145 MVA) as well as engineering and site work. The project will improve the nameplate output of the generators from 166MVA (generators 51 and 53) and 170MVA (generator 52) to 190 MVA.

The project will be managed by GE Renewable Energy's teams based in Denver, CO and Brossard, Canada. Onsite work on the generators covered in this project is set to begin in July 2019 and is scheduled to be completed by May, 2022. The GE Renewable Energy teams are already familiar with the plant for which they had previously been called to refurbish generator 53.
