GE Vernova’s Hydro Power business has been selected by Tacoma Power to refurbish two 27MW/33MVA turbines and generator units at the 81MW Cushman 2 hydropower plant in Washington, US.
The scope of work on two out of the three units installed at the site includes the design, manufacturing, refurbishment, installation and commissioning of new generator stators and refurbishment of generator rotor poles, shaft thrust bearing, as well as two new distributors and refurbishment of runner and draft tubes.
Located in Mason County, the Cushman 2 hydropower plant was commissioned in 1930 and can deliver enough renewable energy for about 40,500 homes in the north-west.
The upgrade is expected to be completed in 2026. The refurbishment/upgrade of the units will help increase availability and reliability for the power plant and deliver more renewable energy to the grid for another 100 years.
