Commercial and Industrial 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 and did not increase our rates in 2016. The Public Service Commission of Wisconsin reviewed our recent request and granted a slight increase of 1.9% in overall natural gas distribution and supply service effective Jan. 1, 2017. Your actual bill depends on your rate classification and usage.

The following natural gas rates are effective for service rendered on and after April 1, 2018.

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