Natural Gas Rates

MGE is serious about our responsibility to provide safe, reliable natural gas service at competitive prices. We work hard to control our costs. In 2018, MGE worked with intervening parties to file a rate settlement agreement to resolve all issues in MGE's rate case. The Public Service Commission of Wisconsin (PSCW) reviewed and approved the settlement agreement, setting our electric and gas rates. Effective Jan. 1, 2020, natural gas rates increased 1.46%

Natural gas rates are separated into two components: Distribution Service and Gas Supply Service. The separation allows you to choose the type of service that’s right for your business.

The following natural gas rates are for services rendered on and after August 1, 2020.

These rates are subject to market variables that may change monthly. Please consult your bill for the most current applicable rates.
