Yorkshire Electricity is looking for a buyer for its 50% stake in two Yorkshire wind farms at Ovenden Moor and Royd Moor. The company entered the wind energy business in a partnership with Yorkshire Water, which owns the other 50% of both plants. The move to pull out of wind farm ownership follows the sale of Yorkshire Electricity's generating business, Yorkshire CoGen, to electricity generator PowerGen. The company says it wants to concentrate on its core business of supply and distribution. While one arm of Yorkshire Electricity is busily divesting itself of its wind assets, the other has begun to market renewable generated electricity to environmentally-minded customers. At the beginning of January, the company launched its green tariff scheme to sell clean power at an 8% premium. Most of the premium will pay for the higher cost of renewable power, says the company. The remainder will be spent on marketing and raising awareness of renewable energy.
