Great Plains Natural Gas (GPNG) Co. is a regulated utility under the jurisdiction of regulatory commissions in the states it serves. The rates customers pay are approved by each state’s regulatory commission. When the costs of providing safe and reliable natural gas service exceed what customers are paying in rates, GPNG files a rate increase request with the applicable state regulatory commission.
Requested increases are the result of additional costs necessary to maintain a safe and reliable system; upgrade aging infrastructure and technology; meet growing demand; and compliance with state and federal regulatory requirements, such as environmental mandates.
The company does not have authority to change rates without approval by a state regulatory commission. Click on your state below to review information about recently approved or pending rate case filings.
Great Plains Natural Gas Co. (Great Plains), a division of Montana-Dakota Utilities Co. (MDU), filed a request to increase natural gas rates with the Minnesota Public Utilities Commission (PUC) on Oct. 30, 2026. If approved, it would increase the monthly bill for an average residential customer by about $12.00.
The primary reasons for the request are increased operations and maintenance expenses, investments made since the company’s last rate filing in 2019, and the corresponding depreciation on those infrastructure investments. These investments are necessary to maintain safe and reliable service.
The proposed net increase is $4.5 million annually over current rates, or about a 12.7% overall increase.
Great Plains serves approximately 22,500 natural gas customers in Minnesota.
Proposed increases by customer class are as follows:
The request is subject to review by the PUC. There is no immediate impact to customer bills during the review process.
Great Plains also filed a request with the PUC for an interim net rate increase of $3.9 million, or 11.23%, over current rates. If approved, interim rates would be implemented while the PUC reviews the overall request. Interim rates allow Great Plains to collect new revenues while the PUC considers the company’s rate request. Revenues collected under the interim rate are subject to refund if the PUC approves a lower amount than the interim rate implemented. If approved, the impact of the interim increase for the average residential customer is about $7.50 per month.
