Fire spreads to West End Road substation in Southampton

EIR-0932

A fire broke out at outbuildings, including a garage, an unused cattery, two sheds and a summerhouse, on West End Road in Southampton shortly before 10:30 BST. The fire spread to the neighbouring electricity substation on West End Road, operated by Scottish and Southern Electricity Networks (SSEN), causing a power cut affecting around 2,000 properties. Hampshire Fire and Rescue Service attended and extinguished the blaze using breathing apparatus by shortly after midday. SSEN restored power quickly to most customers, with the remaining 130 properties closest to the fire reconnected early in the afternoon. No injuries were reported. The cause of the fire was under investigation at the time of reporting.

The fire originated in nearby residential outbuildings and spread to the adjacent substation on West End Road; the precise ignition cause was not confirmed in the source.

  1. Substations located close to residential outbuildings can be vulnerable to fire spread from unrelated ignition sources.
  2. Rapid coordination between fire services and network operators can minimise the duration of resulting power outages.
  3. Investigating fire causes near critical infrastructure helps identify measures to reduce future risk of spread to substations.
