The Snowy Mountains Scheme consists of 9 major power stations – Murray 1, Murray 2, Guthega, Blowering, Tumut 1 (located 366 metres below ground level), Tumut 2 (located 244 metres below ground level), and Tumut 3. Two small hydro power stations have recently been constructed, the Jindabyne Mini Hydro Power Station and the Jounama Small Hydro Power Station.

These 9 power stations have 33 turbines with a total generating capacity of 4100 megawatts (MW) and produce on average, 4500 gigawatt-hours of clean renewable electricity each year, to meet peak power demand.
