End of subsidies for new UK onshore wind farms
New onshore wind farms will be excluded from a subsidy scheme from 1 April 2016, a year earlier than expected.
There will be a grace period for projects which already have planning permission, the Department of Energy and Climate Change said.
Energy firms had been facing an end to subsidies in 2017.
The onshore wind industry attacked the move as a costly political intervention, while trade body RenewableUK called for an urgent meeting with the new energy secretary, Amber Rudd, to discuss the implications of the announcement according to media reports.
