The power outage in southwestern Iowa Thursday occured during construction on a substation in Creston.
Western Area Power Administration (WAPA) employees were finishing construction work at the Creston substation Thursday morning.
“One bus and two lines were de-energized while our employees were working,” said Jennifer Neville, WAPA public affairs specialist. “When they went to reconnect the substation equipment, it tripped the other bus, causing the power outage at 2:26 p.m.”
Of the 10,418 customers Alliant Energy supplies power to in Adair, Adams, Cass, Madison, Montgomery, Ringgold, Taylor and Union counties, 9,379 were without power Thursday.
Ryan Stensland, spokesman for Alliant Energy, said of the 9,379 customers that lost power in those eight counties, 788 were rural customers, while the remaining were identified as residential, commercial or industrial customers.
“Western solved the issue and restored power from the substation to the buses and lines serving Central Iowa Power Cooperative and the International Transmission Company at 3 p.m.,” said Neville.
