Answer: Backup power stations
Explanation: The answer is backup power stations. As wind and solar supply more of Britain’s electricity, gas and other conventional generators may be needed less often. But when renewable output suddenly falls short, those backup plants become essential — and because they have fewer opportunities to earn money, electricity prices may need to spike sharply when they are called upon.
