What applies across South Dakota
Storms on the night of July 28, 2025 brought winds exceeding 65 miles per hour and caused outages for 6,400 customers in South Dakota. By the afternoon of July 29, crews had restored service to more than 5,400 of them.
Sioux Valley Energy says a safety interlock kit with a generator inlet box can generally be installed by its electricians for around $600. It describes this as the safest and most practical way to ready a home for a portable generator connection, and says a permanent standby generator with an automatic transfer switch starts within seconds of an outage.
Before you hire
A generator wired into your home needs an approved transfer switch, fitted under a permit, so it can’t feed power back into the lines. Plan it before you buy.
