A downed wire at a National Grid substation resulted in a power outage for about 1,430 customers along the Route 7 corridor from Niskayuna into Colonie for several hours Monday afternoon.
National Grid spokesman Nate Stone said the incident involved a tree limb falling onto a power line at a substation. It knocked out power in a large area that included the northwestern corner of Albany International Airport. The affected areas included the commercial corridor along Route 7, as well as nearby residential areas.
The airport operations areas didn't lose power and were not affected.
"We have something affecting a couple of (security) gates on Route 7," airport spokesman Doug Myers said.
Smaller parts of Schenectady and Glenville also lost power in the outage.
Power in most of the area was restored by 5 p.m., but an area around Lisha Kill Road didn't get power back until about 6 p.m., according to National Grid.
