Wind farm developers fear National Grid proposals designed to accommodate nuclear power plants will lead to a huge increase in backup costs
Wind farm operators could see their overheads increase by millions of pounds a year as a direct result of plans to upgrade and reinforce the grid to cope with a new fleet of nuclear reactors.
A number of renewable energy developers are angry at National Grid's decision to retain the current charging regime it operates for providing backup power, despite the fact costs are expected to soar when new nuclear power plants come online towards the end of the decade.
National Grid released a consultation document in June detailing how the proposed development of six nuclear power stations would require the grid operator to increase the amount of backup power, known as "spinning reserve", that it has available to call on in the event of a large power plant failing, from 1,320MW to 1,800MW.
The company estimated that as a result, the annual cost of providing so-called Large Loss Response will rise from £160m a year to £319m.
The consultation looked at a number of approaches to charging energy firms to cover the increased cost, but in a letter to Ofgem National Grid commercial director for transmission Alison Kay said the company had decided to retain the current regime, whereby generators are charged an equal amount per megawatt they provide to the grid.
Wind farm operators are known to be furious at the decision, which they claim will see them face an unfair doubling in charges from National Grid, despite the fact the company concluded in its consultation that generators with less than 350MW of capacity, including all operational wind farms in the UK, "pose no additional loss risk to the system".
In contrast, nuclear developers, who argued that targeting the increased charges at larger power plants would jeopardise plans for a new fleet of reactors, are delighted at a decision that will see the increased cost of backup spread right across the energy industry.
