The chief of Scottish Renewables has called on the Government to put an end to uncertainty over funding for onshore wind.

The energy boss recently came head to head with American billionaire Donald Trump about wind farms in Scotland – which were near a planned golf course Mr Trump is investing in.

Now Niall Stuart wants UK ministers to stamp out “speculation” around financial support for onshore wind in mechanisms such as the Renewables Obligation (RO).

This support has been questioned lately, with rumours Chancellor George Osborne wants to cut subsidy by 25%, while a Cabinet Office minister allegedly suggested subsidy for onshore wind could be phased out by 2020.

Mr Stuart, Scottish Renewables’ Chief Executive said: “It’s time the government put an end to the speculation surrounding the support for onshore wind and gives this industry some certainty over its future.

“We have written to the Prime Minister outlining our concerns that any further cut than the 10% reduction already proposed could do considerable damage to investor confidence during a time when onshore wind is the single biggest contributor to renewable energy generation and a significant employer.

“It’s not just the industry that will be impacted but community based projects too. Given their economics these projects will be disproportionately affected, placing at risk significant income for communities across Scotland.”

The Government has so far sidestepped direct response to such concerns.

DECC outlined its position in a statement: “It is vital that our support for renewable electricity both encourages investment and represents value for money for consumers. The Government will publish support levels for renewable electricity technologies for the period 2013 to 2017 shortly.”
