Washburn Generating Station is a single-unit hydroelectric station located on the Cataraqui River in Seeley’s Bay, Ontario. The station has been in service since 1942, and refurbished in 1984. The station has an installed capacity of 0.2 MW at a head of 4.3 metres.

The station is run-of-river without storage capability. The headwork consists of a concrete structure integral with road bridge and waster weir. The concrete intake uses stoplogs to control water. One pressure-treated wood stave penstock conveys water to the concrete powerhouse. Water is discharged into the Cataraqui River.

The station is connected to Canadian Niagara Power’s 26 kV circuit 27-11 from the Gananoque main substation.

This hydroelectric generating station generates approximately 352 MWh of renewable energy per year.
