For several years, Great Plains Natural Gas has been evaluating possible cost-effective solutions to increase the natural gas capacity available to the community of Wahpeton, which lead to the construction of a high-pressure transmission line to Wahpeton. Our natural gas supplier wrapped up the project in late November and as a result, starting on December 1, 2024, natural gas will be supplied to our Wahpeton customers from Montana-Dakota’s integrated natural gas system, rather than from Great Plains via a Minnesota pipeline. This will provide several benefits to Wahpeton customers.
Coinciding with the expansion, Montana-Dakota received North Dakota Public Service Commission approval to integrate Wahpeton customers into Montana-Dakota’s natural gas integrated system under the Montana-Dakota tariff. That means Great Plains customers in Wahpeton will transition to Montana-Dakota customers. Great Plains is a division of Montana-Dakota Utilities, so the change is primarily in name only for Wahpeton customers. The transition will take place in two phases. Great Plains will continue to serve customers only in Minnesota.
On December 1, 2024, as a Wahpeton customer you will no longer be served under the Great Plains North Dakota Gas Rate Schedules, although you will continue to receive a Great Plains bill throughout this phase of the transition. The rate schedules and tariffs under which you are billed and provided service under will be the Montana-Dakota Utilities Co. North Dakota Natural Gas Rate Schedules. The table below provides the rate class and rate schedules before and after December 1 (phase 1). Your new Montana-Dakota rate schedule will be indicated on your monthly bill.
| Rate Class | Great Plains ND (prior to 12/01/24) | Montana-Dakota ND (effective 12/01/24) |
|---|---|---|
| Firm Service | ||
| Residential | Rate 65 | Rate 62 |
| Firm General | Rate 65 | Rate 62 |
| Firm General Contracted Demand | Rate 74 | |
| Interruptible Sales Service | Rate 71 | Rate 71 |
| Interruptible Transportation Service | Rate 80 | Rate 81/82 |
In Phase 2 of the transition Great Plains Wahpeton customers will move to a Montana-Dakota bill versus receiving their bill from Great Plains. This transition will occur during the month of May 2025 so a Wahpeton customer’s first bill from Montana-Dakota will be in June 2025. Phase 2 will not result in any change in natural gas rates for Wahpeton customers.
More information regarding the transition from Great Plains to Montana-Dakota can be found by referencing the December Great Plains Natural Gas Distribution Rate Increase Bill Insert. Please check back as additional and more detailed information on this transition will be posted prior to the actual transition.
Wahpeton customers will continue to receive the same safe and reliable natural gas service they have been receiving for over 50 years. However, that natural gas service will now be provided under the Montana-Dakota tariff and rate schedules instead of under a Great Plains tariff and rate schedule.
No. During this initial phase, you will continue to receive a Great Plains bill and your payment will continue to be made to Great Plains.
May 2025 will mark the last bill you will receive from Great Plains. Beginning in June 2025, you will receive a Montana-Dakota bill and your payment will be made to Montana-Dakota.
No, your natural gas service rates will not change when you start receiving a Montana-Dakota bill. They will be the same Basic Service Charge and Distribution Delivery Charge rates you started paying for your natural gas service on December 1, 2024. The Cost of Gas component of your bill is subject to change from month to month and is strictly a pass-through cost to customers. This cost will continue to be a pass-through cost under Montana-Dakota’s tariff.
During this initial phase, you will be able to continue to access your online account with Great Plains as well as receive your E-bill and payment accomplished through Pay By Bank, no different than they have been. Future communication will outline any changes that may be required of you for continuation with those programs.
Please check this website over the next few months as well as watch for bill inserts and the company’s social media for additional information on this transition. Company personnel will also have open office hours in the Wahpeton area as the May/June 2025 time frame approaches. Company personnel will be available to answer any questions you may have regarding the transition. You can also always reach out to customer service at 1-877-267-4767 with any questions you may have.
