Rochdale's Distribution Network Operator for electricity was United Utilities until 2010, when its electricity subsidiary was sold to Electricity North West. There are no power stations in the town, but Scout Moor Wind Farm which has 26 turbines was built on the high moors between Rawtenstall and Rochdale. The wind farm generates 65MW of electricity. United Utilities manage Rochdale's drinking and waste water. Water supplies are sourced from several reservoirs, including Watergrove, Blackstone Edge, Greenbooth and Piethorne in Rochdale's outlying moorland.
