Improved PSE powerhouse at Snoqualmie Falls

Puget Sound Energy's project manager Dave Jenness at Snoqualmie Falls checks the end of the tailrace, the exit point for water from Powerhouse 1. This is 270-feet below the edge of the falls in the world's first underground hydroelectric plant buried in bedrock. The two power plants at the falls have been upgraded and now will generate 54-megawatts of power, enough for about 45,000 homes, a 20 per cent increase with the same amount of water flow says PSE. The public will have a new, lower level board walk and parking lot and a launch point for kayaks and canoes downstream of the falls. The rock wall behind him is opposite the Salish Lodge at the bottom of the falls.
