The Dunford Generating Station is a two-unit hydroelectric station located on the Michipicoten River. This site was originally developed in 1908, redeveloped in 1929 and most recently, was totally redeveloped between 2001 and 2003, and has an installed capacity of 45 MW at a head of 14 metres.

Located 6 km downstream from McPhail and 4 km upstream from Scott, this station is the third of four power stations on the Michipicoten River. The forebay of Hollingsworth, the most upstream of the stations, serves as the main storage reservoir for this station.

Dunford has two steel penstocks, a gated intake structure, power canal and a five-bay spillway structure. Each penstock is 3 metres in diameter.

Dunford GS is connected to the existing Hydro One circuit at Dunford #1 and #2, and connects to D.A. Watson TS.

This hydroelectric generating station generates approximately 213,353 MWh of renewable energy per year.
