The eye-catching non-Hormuz news in energy-land last month was that Great Britain is set for a record-breaking summer for wind and solar power generation. The national energy system operator even thought there could be periods – a sunny weekend or a bank holiday afternoon of low demand, for example – when more renewable power would be available than the electricity grid needed.
So, on the face of it, it is an odd moment for Centrica, the owner of British Gas, to fork out £370m to buy a 16-year-old combined-cycle gas turbine plant in south Wales. After all, the government’s clean power plan imagines that, come 2030, Great Britain’s entire fleet of gas plants will be used to generate only 5% of its electricity, down from 31.5% in 2025.
