You are the UK Energy Minister, responsible for keeping the national grid stable. Your goal is seven consecutive days of zero-carbon electricity. Keep the lights on, watch the budget, and invest to shift the mix toward renewables — without tipping the country into blackout or political ruin.

You will face supply shocks, infrastructure strain, and changeable weather. The energy mix and events are inspired by how the real UK system balances cost, carbon, and keeping the frequency steady.

Are you tough enough?
