EDF in the UK may be propelled by its disastrous nuclear ambitions, writes Chris Goodall. But across the Atlantic it’s another story: the company is the US’s biggest wind developer, and selling its power, profitably, for under 40% of the price it has been promised for Hinkley C, including federal tax credits. If it continues at the current rate, it will be generating more electricity from wind by 2025 than would be provided by Hinkley Point C. The numbers are as follows. Hinkley will generate about 25 terawatt hours a year. EDF’s 2015 annual portfolio of new wind projects will provide about 3 terawatt hours a year at average US utilisation factors. If it continues to develop new wind projects at the rate of 1 gigawatt a year, it will be generating well over 30 terawatt hours a year from wind by the end of 2025. 2025 is when EDF says Hinkley will be finished. What about the capital cost of wind versus nuclear? The latest US estimates suggest a figure of about $1,700 per kilowatt of capacity. That means EDF’s projects completed in 2015 cost about $1.8bn. Over ten years, that rate of installation will mean a total cost of around $18bn or about £13bn. Wind is therefore at least 30% cheaper to construct.
