Thunderstorms damage equipment at three substations and two transmission lines

Aug 2026Published 28 Sept 2026

On 7 August 2026 a heavy band of strong thunderstorms was reported to have damaged equipment at three substations and affected two transmission lines. By the morning of 9 August, power was mostly restored. An AES outage map at 8:20 a.m. still showed 28 customers without supply in Montgomery County and one in Greene County. The substations were not named, and the report does not say how long the remaining outages lasted.

A heavy band of strong thunderstorms, reported to have hit the area around 3 p.m. on 7 August. No other cause is stated.

  1. One storm band can damage equipment at several substations and affect more than one transmission line, so restoration planning should cover multiple sites at once.
  2. After the wider supply is back, county outage maps can still show small numbers of customers off supply and should be rechecked.
  3. Public updates should keep equipment damage, remaining customer counts and the time of the count separate, because those figures change through the restoration.
