This summer’s heatwaves didn’t just test Britain’s air conditioning, they tested its power grid. With four Electricity Margin Notices issued in a single summer (compared to zero last winter), VPI Chief Executive Jorge Pikunic argues that energy security is no longer a winter-only concern. From still, windless heat that silences renewables to European reactors throttled by warm rivers, he unpacks why gas remains the backbone of Britain’s power system, why price volatility isn’t the enemy it’s made out to be, and why interconnectors can’t be relied on when everyone needs power at once. Read on for his take on what this summer really reveals about the UK’s path to secure, affordable power.
