On-shore wind power cost households less than £5 last year

Despite scaremongering from sections of the the media and the pro gas and nuclear lobby – figures out today show that on-shore wind added less than £5 to household energy bills last year.

Ofgem has just released the Renewables Obligation (RO) annual  report for 2010/11, which is the main support mechanism for encouraging the growth of renewable energy in the UK – including both on-shore and off-shore wind, wave, tidal, biomass and landfill gas.

Ofgem's report shows that the RO added just £15.15 to the annual energy bill of the United Kingdom’s 26.3 million households – with just £4.68 of that supporting on-shore wind.

By comparison, the rising cost of imported gas added around £120[1]  to energy bills last year.

This increase in the cost of gas added more than 10% to energy bills, while support for on-shore wind added less than 0.05%. Ignoring the real reason for rising energy bills – imported gas – 101 Conservative MPs recently wrote to Prime Minister David Cameron saying “in these financially straightened times, we think it is unwise to make consumers pay on-shore wind turbines, through taxpayer subsidy”.

Ecotricity founder Dale Vince said: “Let’s set the record straight. Supporting onshore windmills and making use of our indigenous energy supplies – cost each household less than a fiver last year. 

“This is an investment, not just in clean energy, but in energy security – reducing our reliance on imported gas.   

“There has been a massive campaign of misinformation over the last six months by the media and lobbyists for the gas and nuclear industries – all taking aim at wind energy for some reason. 

“With the rising cost of imported gas increasing household energy bills by £120 last year, it's bizarre to see a group of Conservative MPs complaining about the £5 spent on onshore wind. Are they not in possession of the facts, or do they care little for such inconveniences? 

“In January this year, coal took over from gas as the major provider of electricity in Britain because the high price of importing gas caused the Big Six energy companies to mothball gas power stations. That's the reality - it's gas that we can't afford not onshore wind.   

“Britain should not be left at the mercy of the international gas market. We have 40% of Europe’s wind resource. Let's use it, to create jobs, industries, clean energy and independence from global energy markets.”

Dual-fuel bills rose from £1,145 in 2010 and £1,345 in 2011. The other £80 was increased delivery costs and improved profits for energy companies.

Notes to Editors:

  • Renewables Obligation 2010/2011 = 34,749,418 ROCs ( Ofgem Renewables Obligation Annual Report 2010-11)
  • ROC price = £36.99
  • Value of total obligation = (34.7million ROCs * £36.99) = £1,285,380,972
  • Domestic supply accounts for 31% of UK electricity  ( DECC Digest of UK Energy Statistics Table 5.1)
  • Value of Domestic portion of Renewables Obligation = (£1.2billion * 31%) = £398.5million
  • Number of households in the UK = 26.3million ( Office for National Statistics, Families & Households, 2011)
  • Cost of RO per household energy bill = £398.5million / 26.3million = £15.15
  • Offshore & onshore wind accounted for 51.1% of ROCs in 2010/11 (20.2% and 30.9% respectively) giving a cost per household for wind of (£15.15 * 51.1%) = £7.74. 
  • Cost of onshore wind per household energy bill = £4.68 

Renewables Obligation – The RO came into effect in 2002 in England and Wales and in Scotland and in 2005 in Northern Ireland. It places an obligation on UK electricity suppliers to source an increasing proportion of electricity they supply to customers from renewable sources.

Renewables Obligation Certificates (ROCs) are green certificates issued by the Authority to operators of accredited renewable generating stations for the eligible renewable electricity they generate. Operators can then trade the ROCs with other parties, with the ROCs ultimately being used by suppliers to demonstrate that they have met their obligation.

Where suppliers do not have sufficient number of ROCs to meet their obligation, they must pay an equivalent amount into a ‘buy-out’ fund. The administration cost of the scheme is recovered from the fund and the rest is distributed back to suppliers in proportion to the number of ROCs they produced in respect of their individual obligation.
