Total Electricity Blackout on La Palma in the Canary Islands During Thunderstorm
Endesa said the outage cut 50,508 supply points as officials began restoring service and investigated a fault at the island’s main power station.
- On Monday, the Spanish island of La Palma suffered an island-wide blackout after the Los Guinchos thermal power station disconnected and a fault struck the Guinchos-Valle transmission line managed by REE, cutting power to 50,508 supply points.
- Authorities linked the failure to a violent storm that dumped up to 200 litres of rain per square metre. Endesa reported the plant housed the archipelago's oldest generating units, with upgrades stalled for 12 years due to a delayed public tender.
- Prior to this blackout, a June 10, 2025, fault at Los Guinchos left the island without electricity for nearly three hours. The Canary Islands Government previously flagged ageing generating units and delayed renewal tenders as systemic risks.
- By mid-morning, Endesa had reconnected 8,117 customers while 42,391 remained without power. Canary Islands President Fernando Clavijo urged residents to avoid flooded areas and follow 112 emergency service guidance as authorities declared a state of alert under PLATECA.
- Despite La Palma's participation in the European Commission's Clean Energy for EU Islands initiative, the island remains almost entirely dependent on diesel. Renewables covered barely 10 per cent of peak production in 2025, highlighting the gap between infrastructure and sustainability goals.
