Energy Adjustment and Riders

Minnesota electric service statements include an Energy Adjustment and a Resource Adjustment, which includes five costs. For more information than what you find on this page, please refer to specific rate schedules.

Beginning July 1, 2022, Energy Adjustment rates reflect revised Service Categories and Energy Adjustment Factor ratios as approved by the Minnesota Public Utilities Commission in our 2020 Minnesota Rate Review (Docket No. E017/GR-20-719 Application of Otter Tail Power Company for Authority to Increase Rates for Electric Service in Minnesota).   

On December 1, 2022, the Commission approved the 2023 forecasted monthly rates in Docket No. E017/AA-22-214.

Once a year, we compare actual costs to forecasted costs for the prior calendar year and compute a rate that trues-up the difference.

As approved in the Minnesota Public Utilities Commission’s June 30, 2023 Order in Docket No. E017/AA-21-311 and the automatic adjustment in E017/AA-22-214 filed July 24, 2023, the January 1, 2022, through June 30, 2023, under-collection results in a twelve-month charge of $.0004 per kilowatt hour. This charge will be part of the monthly Energy Adjustment on customer bills from September 1, 2023, through August 31, 2024.

The Conservation Improvement Project (CIP) surcharge represents our investment in energy-efficiency programs that help our customers save energy. The CIP surcharge is based on the total kilowatt-hours (kWh) our customers use and the rate associated with that kWh usage except for Standby Service and those customers who have been granted an exemption.

Our EITE Surcharge Rate applies to customers who do not qualify for the EITE (energy-intensive trade-exposed) Rate. Minnesota's energy policy supports lower electric rates for energy-intensive trade-exposed customers. We automatically exclude customers who receive Low Income Home Energy Assistance Program (LIHEAP) funds from the EITE Surcharge Rate.

EITE Surcharge Rate for bills rendered:
On or after January 1, 2024 $0.00045 per kWh
From December 1, 2022, through December 31, 2023 $0.00034 per kWh

As of January 2014 the Environmental Cost Recovery Rider (ECRR) allows our company to recover costs that we incur to meet state or federal environmental quality requirements for our electric generating facilities. The Minnesota Public Utilities Commission approved our request for an ECRR to include the costs associated with an air-quality control system (AQCS) at Big Stone plant in South Dakota. The AQCS allows Big Stone Plant to meet federal air quality requirements.

The ECRR factor is multiplied by our customers' monthly bills. It does not apply to any Mandatory Riders, sales tax, or any local assessments.

Environmental Cost Recovery Rider factor for bills rendered:
On or after December 1, 2018 0.0 percent
From November 1, 2017, through November 30, 2018 -0.935 percent
From September 1, 2016, through October 31, 2017 6.927 percent

The Renewable Resource Adjustment allows our company to recover costs previously offset by production tax credits associated with our renewable energy facilities. The energy generated by these facilities reduces the amount of fossil fuel and purchased energy necessary to meet our customers' needs.

Revenue Decoupling is an important regulatory tool in the state of Minnesota and has been used by other state utilities to support conservation efforts. In Docket No. E017/GR-15-1033 the Minnesota Public Utilities Commission (PUC) required Otter Tail Power Company to submit a decoupling proposal, which was subsequently reviewed and approved in Docket No. E017/GR-20-719 on a pilot basis, beginning July 1, 2022. The purpose of this rider is to support customer adoption of Distributed Energy Resources and work in conjunction with the Conservation Improvement Program (CIP) by neutralizing the impact of reduced sales due to promotion of energy conservation efforts. The Revenue Decoupling Mechanism (RDM) is applicable to the customers defined in Minnesota rate schedule 13.10, which defines the inputs and calculation of the RDM and subsequent application of the RDM to the customer groups.
