Third Big 6 UK offshore wind farm cancellation or pullout in two weeks.

Guardian: “Scottish Power has abandoned a £5.4bn plan to build the world’s largest offshore wind farm, after four years of planning, because it is “not financially viable”.” “The decision not to go ahead with the Argyll Array, which would have provided green energy for 1 million homes, is another blow to the government’s plans to tackle a looming supply problem and to meet its low carbon targets.
RWE, another of the big six power companies, announced two weeks ago that it was abandoning plans to construct a £4bn offshore wind farm, the Atlantic Array, off Devon. On Thursday, Centrica, owner of British Gas, announced it was selling its stake in another huge offshore wind farm, Race Bank, off East Anglia.
But the Scottish Power move is a particular setback because the company admits that the conditions at Argyll Array, off the coast of Tiree in the Inner Hebrides, are some of the best in the UK. It is a favourite spot for windsurfers. The wind farm was to have up to 300 turbines capable of producing 1,800 megawatts, three times more than the current largest wind farm – the London Array, off Kent – and almost 60% of the output of EDF’s planned new Hinkley Point C nuclear plant. Energy groups have complained that the subsidies available for new wind projects are not high enough. Many have also warned that the lights could go off without more power capacity.
….Earlier this week, Keith Anderson, chief corporate officer of Scottish Power, argued that the “carbon price floor”, which taxes companies for burning fossil fuels, should be shelved by the government because it would make the UK’s remaining coal plants largely uneconomic by the middle of the decade. With Britain’s spare power margin already forecast to fall as low as 2% by 2015, the carbon tax would force more closures and “threatens to make us even more vulnerable to the risk of blackouts”.
