Widespread Blackout Hits Tenerife Following Severe Storms
A widespread power outage caused by severe weather left nearly 160,000 residents in Tenerife without electricity, reigniting concerns over the vulnerability and infrastructure of the Canary Islands' isolated power grid.
The fragility of the Canary Islands' power grid was exposed once again on Sunday, November 1, when a widespread blackout left nearly 160,000 people in Tenerife without electricity. The outage hit areas as far apart as Los Silos, the capital, Las Chafiras, and Costa del Silencio, highlighting how vulnerable the island’s electrical system is to bad weather.
While official numbers are still being confirmed, the scale of the blackout shows how much the grid struggles to stay online during storms. Endesa, the utility company, has pointed to Red Eléctrica as the source of the technical failure, noting that power was gradually restored throughout the morning.
The blackout occurred as a storm brought heavy rain to the island. The State Meteorological Agency (Aemet) had issued an orange alert for the metropolitan area, warning of up to 30 liters of rain per square meter in a single hour. The regional government has kept a rain alert in place for the metropolitan area, with the rest of the island on pre-alert.
This incident has reignited the debate over the resilience of the Canary Islands' electrical system. Because the islands are isolated and lack the grid interconnections found on the mainland, they are particularly vulnerable. The lack of backup systems and the grid's exposure to extreme weather have raised concerns about how the system handles emergencies. It is becoming increasingly clear that modernizing this infrastructure is essential to ensure a stable power supply as severe weather becomes more frequent.
