Ten Mile Lagoon wind farm is situated on a coastal ridge 16 kilometres west of Esperance in Western Australia, and it lies in the northern extremities of the reliable Roaring Forties winds. It was Australia’s first commercial wind farm that is still operating, and consists of nine 225 kW Vestas wind turbines giving a total generating capacity of just over 2 Megawatts. The farm was established in October 1993, after the successful operation of a smaller experimental wind farm at Salmon Beach, Esperance.
