Energy produced in the Australian Capital Territory mainly consists of solar electricity. Electricity consumed in the Australian Capital Territory mainly comes from the national power grid through substations at Holt and Fyshwick (via Queanbeyan). The ACT currently mandates that 100 percent of its electricity, will be supplied from renewable sources by 2020. The ACT has four solar farms capable of generating about 56.3 megawatts. From 1913 until the mid 1950s some power was produced from the Kingston Powerhouse, a thermal power station in Kingston.
