Hydroelectric Power Station

The McKay Creek Power Station is one of four conventional hydroelectric power stations that form part of the Kiewa Hydroelectric Scheme. The McKay Creek Power Station has six generators driven by Pelton wheel turbines, with a total generating capacity of . The Mackay Creek Power Station is located underground on the slopes of Mount McKay. The reservoir at Rocky Valley Dam and a diversion from the reservoir at Pretty Valley Dam, together supply water for the McKay Creek Power Station, via of sub-terrainan tunnels, of surface pipeline, and a steel-lined pressure tunnel.

Water discharged from the McKay Creek Power Station flows down the Pretty Valley branch of East Kiewa River to , and, since 2009, has been used by the Bogong Hydropower Project. The station has capacity for and, in 2015, generated per annum.
