Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Commitments Construction and Other Purchase Commitments: As of December 31, 2021, OTP had commitments under contracts, including its share of construction program and other commitments, extending into 2023 of approximately $68 million. OTP’s other commitments charged to rent expense totaled $0.3 million, $0.1 million and $0.3 million in 2021, 2020 and 2019, respectively. Electric Utility Capacity and Energy Requirements and Coal Purchase and Delivery Contracts: OTP has commitments for the purchase of capacity and energy requirements under agreements extending into 2044. OTP also has contracts providing for the purchase and delivery of a significant portion of its current coal requirements. OTP’s current coal purchase agreements for Coyote Station expire at the end of 2040. OTP has an agreement for the purchase of Big Stone Plant’s coal requirements through December 31, 2022. There is no fixed minimum purchase requirement under this agreement but all of Big Stone Plant’s coal requirements for the period covered must be purchased under this agreement. OTP Land Easements: OTP has commitments to make future payments for land easements not classified as leases, extending into 2050, of approximately $34.5 million. Land easement payments charged to rent expense totaled $1.3 million, $1.3 million and $0.6 million in 2021, 2020 and 2019, respectively. Our future construction program and other commitments, capacity and energy agreement commitments, coal purchase and coal delivery contract commitments and contractual land easements payments as of December 31, 2021 are as follows:

Contingencies FERC ROE. In November 2013 and February 2015, customers filed complaints with the FERC seeking to reduce the ROE component of the transmission rates that MISO transmission owners, including OTP, may collect under the MISO tariff rate. The FERC's most recent order, issued on November 19, 2020, adopted a revised ROE methodology and set the base ROE at 10.02% (10.52% with an adder) effective for the fifteen-month period from November 2013 to February 2015 and on a prospective basis beginning in September 2016. The order also dismissed any complaints covering the period from February 2015 to May 2016. The November 2020 opinion is subject to judicial review. We have deferred recognition and recorded a refund liability of $2.5 million as of December 31, 2021. This refund liability reflects our best estimate of required refunds to customers once all regulatory and judicial proceedings are finalized. Regional Haze Rule (RHR). The RHR was adopted in an effort to improve visibility in national parks and wilderness areas. The RHR requires states, in coordination with the EPA and other governmental agencies, to develop and implement plans to achieve natural visibility conditions. The second RHR implementation period covers the years 2018-2028. States are required to submit a state implementation plan to assess reasonable progress with the RHR and determine what additional emission reductions are appropriate, if any. Coyote Station, OTP's jointly owned coal-fired power plant in North Dakota, is subject to assessment in the second implementation period under the North Dakota state implementation plan. In September 2021, the North Dakota Department of Environmental Quality (NDDEQ) made public a draft of its state implementation plan. The plan concluded it is not reasonable to require additional emission controls during this planning period. Following a consultation and public comment period, and any subsequent modifications to the plan, the NDDEQ will submit its state implementation plan to the EPA for approval. In January 2022, prior to the submission to the EPA by the NDDEQ, the EPA provided preliminary comments on the draft North Dakota state implementation plan in which it expressed disagreement with the NDDEQ's recommendation to forgo additional emission controls. We cannot predict with certainty the impact the state implementation plan may have on our business until the state implementation plan has been approved or otherwise fully acted on by the EPA. However, significant emission control investments could be required and the recovery of such costs from customers would require regulatory approval. Alternatively, investments in emission control equipment may prove to be uneconomic and result in the early retirement of, or the sale of our interest in, Coyote Station, subject to regulatory approval. We cannot estimate the financial effects such a retirement or sale may have on our consolidated operating results, financial position or cash flows, but such amounts could be material and the recovery of such costs from customers would be subject to regulatory approval. Westmoreland Coal Company (Westmoreland) Arbitration. In December 2018, insurers for Westmoreland, Westmoreland and its affiliated companies filed an arbitration demand against the co-owners of Coyote Station, including OTP, a 35% co-owner. The claimant insurers were pursuing recovery in the amount of $5.5 million, plus prejudgment interest to recover business interruption insurance proceeds paid to Westmoreland or its affiliates arising from a boiler feed pump explosion in December 2014 at the facility. The explosion and ensuing repairs reduced the amount of coal purchased from a Westmoreland affiliate under an existing coal purchase agreement. The Westmoreland insurers claimed the co-owners breached the minimum purchase obligations in the coal purchase agreement. As of December 31, 2021, an agreement to settle the matter was reached, and OTP's proportionate share of the settlement payment did not have a material effect on its 2021 financial results. Other Contingencies. We are party to litigation and regulatory enforcement matters arising in the normal course of business. We regularly analyze relevant information and, as necessary, estimate and record accrued liabilities for matters in which a loss is probable of occurring and can be reasonably estimated. We believe the effect on our consolidated operating results, financial position and cash flows, if any, for the disposition of all matters pending as of December 31, 2021, other than those relating to the RHR, will not be material.
