Storm Austen highlights vulnerability of electricity supplies during severe weather

Storm Austen brought damaging winds, electricity interruptions and transport disruption to parts of southern Britain on Friday 23 October 2026.

The first named storm of the 2026/27 season affected the South West particularly severely, with the Met Office recording gusts of 76mph at St Mary’s Airport in the Isles of Scilly.

Gusts of 74mph were also recorded at Aberporth in Wales, while Culdrose in Cornwall recorded 71mph says the Met Office.

Electricity networks affected

Thousands of properties experienced interruptions to their electricity supplies during the storm.

Electricity network operator National Grid recorded numerous faults across its network on 23 October.

Individual incident records show the scale of disruption in some areas.

One interruption affecting 1,533 properties in the TQ12 and TQ13 postcode areas was reported at 8.39am, with supplies restored by 9am.

Another incident affecting 1,001 properties in the TR8 area was reported early on Friday morning. National Grid recorded full restoration at 1.43pm on Saturday 24 October.

These examples illustrate how restoration times can vary considerably between incidents.

Why storms cause power cuts

High winds can damage overhead electricity lines, bring down trees and dislodge equipment.

Heavy rain and flooding can also make it difficult for engineers to reach damaged infrastructure.

Although electricity companies maintain contingency plans, restoration may take longer when weather conditions prevent repairs from being carried out safely.

Before Storm Austen arrived, Scottish and Southern Electricity Networks had increased staffing and contacted more than 500,000 customers by text as part of its preparations.

Preparing for future electricity interruptions

Households can reduce the inconvenience of a power cut by keeping essential supplies accessible.

A charged power bank, battery-powered torch, radio and food that can be eaten without cooking are useful starting points.

It is also worth remembering that many gas central heating systems require electricity to operate.

People who rely on electrically powered medical equipment should have a specific contingency plan and check whether they qualify for additional support through the Priority Services Register.
