The UK is undergoing the most significant upgrade of its national grid since the 1960s. Over the next five years, more than £10 billion will be spent on the country’s high voltage electricity network as the infrastructure adapts to the growing use of renewables, which have transformed how and where power is generated. “We’re rapidly moving from a world where we had fewer points of power generation – from large power plants such as coal, gas and nuclear – to a place where there are millions of renewable projects feeding into national grids,” says Hiscox London Market’s Louis Cozon, Power and Renewables Line Underwriter.
