The Electron Hydroelectric Project ( English Electron Hydroelectric Project ) of Puget Sound Energy at the Puyallup River in Pierce County , Washington is a power plant from 1904 with a maximum capacity of 22  MW .

location

The hydropower plant is located on the Puyallup River near Kapowsin in Pierce County, about 40 kilometers southeast of Tacoma and 68 kilometers southeast of Seattle at the foot of a western foothill of Mount Rainier .

technology

The system, which was completed in 1904, takes water from the Puyallup River and guides it through a 16-kilometer wooden channel above the river, which flows into a deep gorge, into a basin above the power house . The wooden gutter has a cross-section of 2.4 m × 2.4 m and can lead up to 11 m³ / s into the storage basin above the pressure pipes of the power plant. The power house has four machine sets, three of which have an output of 5.5 MW each and one with an output of 7.8 MW.

A railway line was built on the upper edge of the channel to transport maintenance personnel, cranes and materials. It claims to be the windingest railway line in the world ("the crookedest railway in the world"), but it is not the only railway line that makes this claim.

The channel and railway were rebuilt in 1985 on the existing route using Nootka false cypress wood with a polyurea coating .
