GE VERNOVA’S HYDRO POWER BUSINESS TO UPGRADE CUSHMAN II HYDROPOWER PLANT, USA
Located in Mason County, Washington, USA, the 81 MW Cushman II hydropower plant was commissioned in 1930, and can deliver enough renewable energy for about 40,500 homes in the Northwest.
GE Vernova’s Hydro Power business has been selected by Tacoma Power to refurbish two 27 MW/33 MVA turbine and generator units at the Cushman II hydropower plant, out of the three units installed at the site.
The scope of work includes the design, manufacturing, refurbishment, installation and commissioning of two new generator stators and refurbishment of generator rotor poles, shaft thrust bearing, as well as two new turbine distributors and refurbishment of turbine runner and draft tube.
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.
Hydropower projects are set to be operational for the very long term, meaning that the projects will provide a large amount of renewable energy for several generations to come. A typical hydropower facility can have an operating life of more than a hundred years, if maintained regularly, without having to re-build dams.
