It follows a recent announcement of up to £9 billion investment from Japan into the UK’s offshore wind industry, and Rolls-Royce SMR winning a multi-billion-pound Sweden nuclear export contract off the back of the UK’s pioneering SMR programme. Meanwhile today (Tuesday 23 June), National Grid confirmed £1.2 billion of contracts to upgrade 1,000km of transmission lines.
