The Hogg Generating Station is a single-unit hydroelectric station located on the Montreal River. The station was built in 1965, and has an installed capacity of 18.0 MW at a head of 24 metres.

Located 3 km upstream from the Andrews, this station is the third of four stations located on the Montreal River. The Hogg forebay is small and renders the station a run-of-river type operation.

Hogg has a single penstock.

Hogg GS is connected to the existing Hydro One 115kV line at Gartshore GS, which in turn connects to MacKay TS.

This hydroelectric generating station generates approximately 72,747 MWh of renewable energy per year.
