Failure to accelerate updates to Britain’s ageing power grid to handle rising renewable generation could cost consumers billions of pounds by 2030, the official spending watchdog has warned.
Up to £70 billion in investment is required over the next five years to upgrade and maintain Great Britain’s transmission network. Constructed predominantly between the 1950s and 1970s around major fossil fuel power stations, the infrastructure is now outdated and poorly suited to the rapid boom in renewable electricity.
