Resource Adjustment

The Minnesota Resource Adjustment includes six costs. For more information than what you find on this page, please refer to specific rate schedules.

Effective January 1, 2020, the Minnesota Energy Adjustment includes the forecasted cost of fuel to generate electricity to serve our retail customers, forecasted transportation costs for that fuel, and forecasted costs we will incur to buy energy to supplement our own power plants, minus a base cost for energy that already is part of the per-kilowatt-hour rate you pay.

Once a year, we compare actual costs to amounts collected from customers through base rates and the Cost of Energy (COE) over the same time-period and compute a rate that trues-up the difference over the next 12 months.

For the 18 months ending December 31, 2019, the true-up rate will be a credit of ($.0005) per kilowatt‑hour. This credit will be part of the monthly COE adjustment on customer bills from March 1, 2020, through February 28, 2021. The rates reflected below have been updated to include this annual true-up adjustment.

On May 14, 2020, Otter Tail filed a Petition requesting approval of a reduction to fuel cost charges for the July through September 2020 period. The $0.0057/kWh reduction has been provisionally implemented in the rates below.

The Conservation Improvement Program (CIP) surcharge represents our investment in energy-efficiency programs that help our customers save energy.

The CIP surcharge is based on the total kwh our customers use.

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 will allow 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.
