Most wind farms in Britain will not be economically viable when existing subsidies end and will close prematurely without further revenue support, new analysis suggests. A report commissioned by SSE has found that the huge expansion of wind power in the UK is likely to push wholesale electricity prices so low on windy days that most wind farms will be unable to cover their operating costs simply from selling power into the market. This could lead to mass early closures of offshore and onshore wind farms when their existing subsidy arrangements end, primarily from the 2030s. Building new wind farms to replace them could increase the costs of hitting Britain’s net zero target by £20 billion, the report says. It argues that it would be far cheaper to offer continuing revenue support to extend the life of the existing projects or upgrade them, such as “repowering” existing sites with bigger turbines. At present, only brand new projects are eligible for such support.
