Under-use of wind turbines to win subsidies is giving renewable energy a bad name and should be reviewed by the Commons, a Tory MP said.
Dan Byles said unscrupulous onshore wind developers were building large turbines but running them below capacity to secure subsidies - and insisted the Department for Energy and Climate Change (DECC) is aware of the issue.
Responding to calls for MPs to debate the issue, Leader of the House Andrew Lansley said the Government was committed to cracking down on the practice.
Speaking during the weekly business statement in the Commons, North Warwickshire MP Mr Byles said: It is now apparent that the DECC have been aware for some time of the practice by some unscrupulous onshore wind developers of derating, whereby they will install a large wind turbine, they will run it at a sub-optimal level in order to benefit from the higher subsidies that are supposed to be available to small developers.
When can we have an urgent debate on this subject which costs consumers money and gives renewable energy a bad name?
Mr Lansley said: Im sure you will know that ministers at DECC do take this issue very seriously. Ministers have acted to tackle a similar issue in relation to hydro sites (and) are committed to doing the same for wind.
They have discussed the issue with wind turbine manufacturers and Renewables UK.
