Aubrey Falls Generating Station is a two-unit hydroelectric station located on the Mississagi River, approximately 110 km northeast of Sault Ste. Marie. The station was built between 1966 and 1969 with an installed capacity of 162 MW.

The station is the most upstream of three stations along the Mississagi River, and is located 86 km upstream of Rayner and Wells.

Aubrey has two separate penstocks supplying each unit and are separated by a single pier. Each inlet consists of a single water passage and is equipped with a trash rack. Each inlet has a separate vertical lift headgate and a service opening upstream of the headgate. Each penstock is 109.7 metres in length and 7.7 metres in diameter.

Aubrey is connected to the existing Hydro One 230kV circuits P25W and P26W, and connects with Mississagi TS and Wawa TS.

This hydroelectric generating station generates approximately 170,610 MWh of renewable energy per year.
