The subsidy for onshore wind energy generation is to be cut by 10%, the government has announced.
The Treasury is thought to have favoured a larger cut of up to 25%.
It is one of a number of cuts which the Department for Energy and Climate Change said should encourage up to £25bn in new investment in energy generation between 2013 and 2017.
The measures should also reduce the impact on household energy bills, it said, saving £5-£6 a year on average.
