Electricity will be shut down for several hours starting at midnight on Saturday, Nov. 9.
The power outage could last as long as six to eight hours, according to Mark Shockley of Alliant Energy.
“It’s going to be extensive,” Shockley told the Manawa Common Council at its Oct. 21 meeting. “There’s lots of work to be done out there.”
The blackout will include the city of Manawa and portions of the townships of Little Wolf, Union and St. Lawrence, and the village of Ogdensburg.
When Alliant switches the substation, they hope to back feed electrical power from Iola and Marion to portions of St. Lawrence/Ogdensburg and the township of Union, respectively.
Alliant is moving the high lines and upgrading power supplies to the area.
According to Shockley, the systems were overloaded. He said the upgrade is needed and the system will be “greatly improved.”
Two emergency units will be staffed during the power outage, according to Manawa Fire Chief Rob Rosenau.
“With the colder weather, I’m a little concerned people will use heaters, etc.,” he said during a Fire Board meeting on Oct. 22.
There are also health concerns, according to Dan Williams, consultant to the Manawa Ambulance and Manawa Rural Fire Department.
Williams said the blackout will affect anyone dependant on oxygen machines, ventilators, etc. He noted these people will need to take extra precautions.
Alliant Energy plans to send messages to all affected customers via a computer generated calling system.
“Not everybody will get that phone message,” Williams said.
