The Murray Region Hydroelectric Power Stations refers to two of seven hydroelectric power stations, both located near the town of Khancoban in the Snowy Mountains region of New South Wales, Australia. The two power stations are part of the Snowy Mountains Scheme, a vast hydroelectricity and irrigation complex constructed in south-east Australia between 1949 and 1974 and now run by Snowy Hydro. Although both power stations are physically located in New South Wales, since 1 July 2008 all power generated has been allocated to the Victorian region of the National Electricity Market. The stations are not located on the Murray River.

Murray 1 Power Station
Murray 1 Power Station is located 10 kilometres (6.2 mi) north of Khancoban along the Alpine Way. The conventional gravity-fed hydroelectric power station has ten, vertical Francis, Boving Engineering UK-manufactured turbines, each fitted with ASEA-manufactured generators, with a combined generating capacity of 950 megawatts (1,270,000 hp) of electricity. The power station was completed in 1967, and has 460.2 metres (1,510 ft) rated head. Fed by natural inflow, supplemented by the pumped flows of the Snowy-Geehi Haupt-tunnel from Island Bend Pondage, it receives water from the Geehi Reservoir on the Geehi River and discharges into the Murray 2 Pondage. The station is capable of producing enough electricity to supply over 95,000 homes.
Murray 1 will undergo a series of outages, from 2013 to 2022 inclusive, in order to complete maintenance on each turbine and generator.
A Snowy Hydro Visitor Centre is on site at Murray One.
Murray 2 Power Station
Murray 2 Power Station is located approximately 5 kilometres (3.1 mi) southeast of Khancoban. The conventional gravity-fed hydroelectric power station has four, vertical Francis, turbines of Hitachi manufacturing in Japan, each coupled to ASEA generators, with a combined generating capacity of 550 megawatts (740,000 hp) of electricity. This site was the first use of Japanese supply of large electrical and mechanical components in the Snowy Scheme. The power station was completed in 1969, and has 264.3 metres (867 ft) rated head. Fed by the water discharged from Murray 1 Power Station into the Murray Two Pondage, Murray 2 Power Station discharges water into the Khancoban Pondage, and into the Swampy Plain River.
Murray 2 will undergo a series of outages, during 2020 to 2022 inclusive, in order to complete maintenance on two of the turbines and generators.
