North Dakota Energy Adjustment and Riders

North Dakota electric service statements include an Energy Adjustment and three riders. For additional information please refer to specific rate schedules.

Energy Adjustment

The Energy Adjustment includes the cost of fuel we use to generate electricity to serve our retail customers, transportation costs for that fuel, and costs we incur to buy energy to supplement our own power plants. Effective February 1, 2019, each service category (listed below) will have its own rate.

Interim Rate Rider

The Interim Rate Rider is an interim increase that’s in place while the Public Service Commission reviews our November 2, 2023, request to increase rates. As part of our November request, we have lowered the other rider rates (two of them to zero), and moved them into this rider. The net effect of the new Interim Rate Rider and the lowering of the other rider rates is a 6.03% increase. For more information on the ND Rate Case please visit North Dakota Rate Case | Otter Tail Power Company (otpco.com).

Interim Rider for bills rendered:
On or after January 1, 2024                                          30.51%*

* 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. The net increase is an average of 6.03%.
