Wind energy prices reached a high of over £0.09 per kilowatt hour in the latest auction of renewable power. A total of 766 MW of green electricity supported under the UK's now defunct Non Fossil Fuel Obligation (NFFO) was sold off to ten bidders in the online auction, held in August. Wind achieved an average price of £0.0905/kWh, not as high as hydro (£0.0941/kWh) or landfill gas (£0.0931/kWh). The contracts are for six months of electricity to be produced from October to March. Because the auction covers a winter period, prices were expected to be higher than the previous auction, which produced an average price of £0.0668. Market prices have been further pushed up by recent rises in fossil fuel prices.
