Blackout planning: Berlin arson, Spain's 2025 collapse and the BBC 'black sky' plan

Large power failures are rare but real: Spain and Portugal's 2025 blackout, a deliberate arson attack in Berlin, a foiled attack on Poland's grid. The BBC and UK government are planning for a long, widespread power and communications failure as a low-probability event.
Timeline
- ENTSO-E's expert panel published its final report on 20 March 2026 on the 28 April 2025 blackout, which cut power across Spain and Portugal. It found no single cause, pointing to a combination of voltage-control weaknesses, generators and inverters disconnecting, oscillations and limited real-time monitoring, and made 22 recommendations. The report describes itself as expert analysis, not an attribution of liability.
- A fire on high-voltage cables near the Lichterfelde plant on 3 January cut power to up to 45,000 households and more than 2,000 businesses. Many homes also lost heating and hot water in sub-zero temperatures, and full restoration was not expected until several days later. A left-wing extremist group claimed responsibility, police called the claim credible and the mayor described it as terrorism.
Be ready: A torch, a wind-up or battery FM radio and a charged power bank cover the first hours of any power cut, whatever the cause.
