On La Palma there was another partial power cut in the early hours of Wednesday, 4 November 2026. According to consistent reports from Europa Press, RTVC and La Razón around 13,740 connections were without power for approximately 22 minutes . The incident was recorded at around 07:23 local time; service was restored shortly afterwards.
As the immediate cause, Endesa cited the unplanned shutdown of several generating units at the Los Guinchospower station. The precise cause of the fault is being investigated. According to media reports, Red Eléctrica coordinated the stabilisation of the grid and reconnection after the affected units had been restarted. There were initially no reports of injuries or significant material damage.
The outage occurred just two days after the complete blackout on 2 November 2026, known on the island as a cero energético . At the time, La Palma was temporarily left without electricity altogether. The latest incident has intensified the debate about the vulnerability of the island’s electricity supply and the need for rapid technical upgrades. While the cause is being investigated, the operators say that security of supply is a priority and that temporary measures to stabilise the grid are in place.
Endesa announced that it would carry out more detailed internal analyses of the affected units at Los Guinchos. According to reports, Red Eléctrica said that island grids can be more sensitive to sudden changes in load or generation than the Spanish mainland grid, because of their size and structure. Experts see this as a reason to regularly update automatic protection and restart systems in the Canary Islands.
The sequence of events—a complete outage on 2 November and a partial outage lasting 22 minutes on 4 November 2026—has once again brought the maintenance and modernisation of generating facilities into focus. Political assessments and the assignment of responsibility initially remained muted; no reliable figures on financial consequences are available. According to the authorities involved, the priority is to establish the technical cause and prevent further shutdowns during normal operations.
Based on the information currently available, the verifiable key facts are: the date and time of the incident (4 November 2026, approximately 07:23), the duration of the interruption (22 minutes), the approximate number of affected connections (13,740), the location of the fault (Los Guinchos power station) and the ongoing investigations by Endesa in coordination with grid operator Red Eléctrica.
