Fire at Pennsylvania substation triggers multi-day power outage

A fire broke out at a Met-Ed (FirstEnergy) electrical substation in Gardners, Adams County, Pennsylvania, at around 8:50pm on 23 June 2025, during a period of high heat and demand. The fire initially disrupted power to about 13,500 customers. Firefighters extinguished the blaze quickly, allowing restoration to roughly 8,000 customers, but around 5,500 remained without power the following day, with repairs expected to take multiple days. Separately, a transformer failure at a nearby Met-Ed substation in Littlestown left over 4,000 customers without power the same night. FirstEnergy mobilised temporary substations and crews worked around the clock to restore supply, while affected cooperatives rerouted transmission to partially restore service to some substations.

The outages occurred during a period of extreme heat, increasing electrical demand and strain on the grid. The exact cause of the Gardners substation fire had not been determined at the time of reporting, and the operator stated a full assessment would follow once power was restored.

1. Extreme heat events can increase strain on ageing grid infrastructure and elevate the risk of equipment failure.
2. Rapid fire service response can limit fire damage and shorten the restoration timeline despite complex electrical repairs.
3. Utilities should have contingency plans, such as temporary substations and mutual aid with adjacent utilities, to expedite restoration during multi-site outages.
4. Clear public communication and support programmes (for example water and cooling stations) are important during extended outages coinciding with heat waves.
