Utility customers in Shawano and Clintonville can expect a decrease in utility rates starting in September, which they’ll see on their October electric bills, partly thanks to corporate tax breaks passed in Congress last year. The Badger Power Marketing Authority, where Shawano Municipal Utilities and Clintonville Water and Electric get their power, is reducing its electric rates starting next month by about 5 percent. Badger Power Marketing Authority is a partnership between the cities of Shawano and Clintonville started in 1984 as a way to join together and purchase wholesale electric power in larger contract blocks to save money for the electric customers of SMU and CWE.
