Copeton is AGL's largest hydroelectric power station in New South Wales, located 340 metres downstream from the Copeton Dam. The Copeton Dam has a storage capacity of around 1,364 GL and experiences variable water flow. Similarly to the Burrendong Dam, the primary purpose of the Copeton Dam is to supply irrigation for farming, domestic and industrial needs. The dam's secondary purpose is to provide a measure of flood mitigation. Dam releases required by State Water are made to assist in wildlife conservation in downstream areas, especially in the lower reaches known as the Watercourse country . The station has two Kvaerner turbines, giving a total generating capacity of 22.5 MW.
