The 19 turbine wind facility is expected generate enough renewable electricity to power approximately 21,000 homes annually, based on an average annual domestic household consumption of 4,700kWh.
E.ON regional director of renewables in the UK Dave Rogers said the development will not only provide clean renewable electricity for Scotland, but will also enable the nation to meet its renewable energy targets.
Presently, the company is engaged in developing two new onshore wind facilities near Caithness and Rosehall in the Highland.
The company also owns and operates a biomass power station in Lockerbie and Robin Rigg, which was completed in 2010.
Earlier E.ON also won the exclusive right to explore the potential for new wind energy projects on two lots of land owned by Forestry Commission Scotland.
