No companies have bid for the UK’s latest round of offshore wind farms in a step seen as a serious setback for the Government’s climate change ambitions, after months of warnings from industry players. With Rishi Sunak discussing the transition to net zero at a G20 summit in India, the lack of interest in the annual auction round put a dent in ministers’ promise to deliver 50 gigawatts (GW) of offshore wind by 2030. Analysts said the offshore failure will add £1 billion to UK energy bills with the power grid forced to rely more on the volatile gas market, where prices soared after Vladimir Putin’s invasion of Ukraine.
