The Red Rock Falls Generating Station is a two-unit hydroelectric station located on the Mississagi River. The station was designed and built by Ontario Hydro between 1958 and 1961, where the first unit was placed in service on November 5th 1960 and the second unit placed in service on January 13th 1961. The station has a total installed capacity of 41 MW at a head of 28.4 metres.

Located 24 km downstream of Rayner and Wells at the end of the Mississagi River, this station is known to cause a bottleneck. Wells and Rayner has a flow rate capacity of 515 m3/s, whereas Red Rock has a flow rate capacity of 180 m3/s. As a result, the water level at Red Rock forebay can build up fast during wet seasons. As a result, water level is controlled by spilling excess water through seven sluice gates.

Red Rock has two penstocks, each with two headgates. On each penstock there is single headgate that will be used to prime the penstock if the headgates were to drop and the penstock were to empty. Each penstock is 24.4 metres in length and 5 metres in diameter. The forebay has a maximum elevation of 208.90 metres and a minimum elevation of 207.3 metres.

Red Rock is connected to the existing Hydro One 115kV circuit T1B, which is the same circuit used by Rayner. Circuit T1B, in turn, connects to the 230kV Algoma TS.

This hydroelectric generating station generates approximately 190,191 MWh of renewable energy per year.
