About 1,700 National Grid electric customers from Potsdam to Parishville lost power for a few hours last night due to a malfunction at a substation.
Witnesses in Potsdam said they heard a boom and saw a flash at about 8:50 p.m.
National Grid spokeswoman Virginia Limmiatis said the outage was caused by an equipment malfunction at the Lawrence Avenue substation in Potsdam, but could not say what piece of equipment failed.
The area affected included about half the village of Potsdam, mainly the eastern half, and extended east out State Rts. 72 and 11B, and some distance beyond those roads, to Parishville and Southville.
Limmiatis said about half of the customers had power restored by midnight, and the rest by 1:50 a.m.
National Grid’s power outage web page also showed about 80 Canton customers affected by an earlier power outage, centered at either end of Jingleville Road.
