North Dakota Rate Case

On November 2, 2023, we submitted an application to the North Dakota Public Service Commission (PSC) for permission to increase our electric rates. The filing starts a nearly year-long process, often referred to as a rate case.

During this time the PSC reviews costs we incur to provide you with energy and related services and then determines the appropriate prices for using those services. This independent, public process helps ensure transparency and fair rates for all customers.

The primary driver behind our request was increased costs to maintain a safe and reliable system while meeting growing electricity demand. High interest rates and changes in our customer mix also contributed to the timing.   

How this could impact you

Interim rates

The PSC approved our request to increase rates by $34.4 million on an interim basis beginning January 1, 2024. We expect interim rates will remain in effect until early 2025.

About $22 million of this interim increase is already being billed in individual rider line items under "Other Charges/Credits" and simply moves to the new "Interim Rate Adjustment" line item. To move this charge and collect the additional $12.4 million, we apply a 30.51% increase to select charges, including the customer, energy, demand, facilities, fixed, and monthly minimum charges as applicable. 

With this interim rate increase, you’ll see an average net increase of 6.03% on your monthly electric service statements.  

Due to the movement of cost recovery from riders to the Interim Rate Adjustment, the Renewable Rider and the Generation Rider are zero. We’ve also updated the Transmission Rider and Metering & Distribution Technology Rider rates. You’ll see these charges on the Other Charges/Credits portion of your bill. Visit How to read My Bill for more information. 

If the PSC approves final rates lower than interim rates, we’ll refund you the difference with interest. If final rates are higher than interim rates, we won’t charge you the difference.  

The table below shows interim increases to typical monthly bills for each customer type. Increases vary depending on your electric service rate and the amount of electricity you use.

Final rates 

We requested permission for an increase to rates of approximately $40.6 million. A portion of this amount, $23.3 million, is already being billed via riders as we've outlined in the above interim rates section.

On December 30, 2024, the PSC approved a $13.1 million net increase to our electric service rates. This average net increase of 6.18% keeps our electric service rates among the lowest in the nation. 

We'll propose to implement approved rates approximately 120 days after the PSC final order becomes effective, likely in the first quarter of 2025. And because interim rates closely match final approved rates, you won't see a significant bill impact when we implement final rates.
