Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Overview Otter Tail Corporation and its subsidiaries (collectively, the "Company", "us", "our" or "we") form a diverse, multi-platform business consisting of a vertically integrated, regulated utility with generation, transmission and distribution facilities complemented by manufacturing businesses providing metal fabrication for custom machine parts and metal components, manufacturing of extruded and thermoformed plastic products, and manufacturing of PVC pipe products. We classify our business into three segments: Electric, Manufacturing and Plastics. Basis of Presentation The unaudited consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the SEC for interim reporting. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles. In the opinion of management, we have included all adjustments, including normal recurring accruals, necessary for a fair presentation of the consolidated financial statements for the periods presented. The consolidated financial statements and condensed notes thereto should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020. Because of the coronavirus (COVID-19) pandemic, the seasonality of our businesses and other factors, the earnings for the three and nine months ended September 30, 2021 should not be taken as an indication of earnings for all or any part of the balance of the current year or as an indication of earnings for future years. Use of Estimates We use estimates based on the best information available in recording transactions and balances resulting from business operations. As better information becomes available, or actual amounts are known, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates. |

Segment Reporting [Abstract] | |
Segment Information | Segment Information We classify our business into three segments, Electric, Manufacturing and Plastics, consistent with our business strategy, organizational structure and our internal reporting and review processes used by our chief operating decision maker to make decisions regarding allocation of resources, to assess operating performance and to make strategic decisions. Certain assets and costs are not allocated to our operating segments. Corporate operating costs include items such as corporate staff and overhead costs, the results of our captive insurance company and other items excluded from the measurement of operating segment performance. Corporate assets consist primarily of cash, prepaid expenses, investments and fixed assets. Corporate is not an operating segment, rather it is added to operating segment totals to reconcile to consolidated amounts. Information for each segment and our unallocated corporate costs for the three and nine months ended September 30, 2021 and 2020 are as follows: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 Operating Revenue 1 Electric $ 118,775 $ 115,213 $ 348,629 $ 333,213 Manufacturing 89,977 59,849 250,085 174,276 Plastics 107,542 60,693 264,898 155,769 Total $ 316,294 $ 235,755 $ 863,612 $ 663,258 Net Income (Loss) Electric $ 22,528 $ 24,737 $ 55,547 $ 54,225 Manufacturing 4,200 3,311 15,290 8,476 Plastics 28,410 10,343 60,102 20,922 Corporate (2,384) (2,457) (5,787) (6,440) Total $ 52,754 $ 35,934 $ 125,152 $ 77,183 1 Amounts reflect operating revenues to external customers.

The agreements both provide for $170 million revolving lines of credit to support operations, and borrowings which may be used for working capital needs and other capital requirements, to refinance certain indebtedness and for the issuance of letters of credit in an aggregate not to exceed $40 million for the OTC Credit Agreement and $50 million for the OTP Credit Agreement. Each credit facility includes an accordion provision allowing the borrower to increase the available borrowing capacity, subject to certain terms and conditions. The borrowing capacity of the OTC Credit Agreement can be increased to $290 million and the OTP Credit Agreement can be increased to $250 million. Borrowings under each credit facility are subject to a variable rate of interest on outstanding balances and a commitment fee is applied based on the average unused amount available to be drawn under the respective facility. The variable rate of interest to be charged is based on either LIBOR or a Base Rate, as defined in the agreement, selected by the borrower at the time of an advance, subject to the conditions of each agreement, plus an applicable credit spread. The credit spread ranges from 0.125% to 2.00% for the OTC Credit Agreement and from zero to 1.75% for the OTP Credit Agreement, depending on the benchmark interest rate selected and is subject to adjustment based on the credit ratings of the borrower. As of September 30, 2021, the weighted-average LIBOR Rate based interest rate was 1.59% and 1.33% under the OTC Credit Agreement and OTP Credit Agreement, respectively. Each credit facility contains a number of restrictions on the borrower, including restrictions on their ability to merge, sell assets, make investments, create or incur liens on assets, guarantee the obligations of any other party and engage in transactions with related parties. The agreements also contain certain financial and non-financial covenants and defined events of default, and include provisions for the replacement of the LIBOR benchmark rate in the event that LIBOR is no longer available.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Commitments Construction and Other Purchase Commitments. OTP has commitments under contracts, including its share of construction program and other commitments associated with its jointly-owned facilities, extending into 2046. 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, with expiration dates ranging from 2022 through 2040. Certain contracts do not include minimum purchase requirements but do require all coal necessary for the operation of the respective plant to be purchased from the counterparty. Land Easements. OTP has commitments to make future payments under land easements extending into 2050. Contingencies FERC ROE. In November 2013 and February 2015, customers filed complaints with FERC seeking to reduce the ROE component of the transmission rates that MISO transmission owners, including OTP, may collect under the MISO tariff rate. 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 $3.0 million as of September 30, 2021. This refund liability reflects our best estimate of required refunds to customers once all regulatory and judicial proceedings are completed. 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. 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 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 an 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 are 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 claim the co-owners breached the minimum purchase obligations in the coal purchase agreement. As of September 30, 2021, we have recorded an estimated liability for losses to be incurred related to this matter based upon the most recent information available, however, ultimate losses could be in excess of the amount recorded. Any losses incurred from this matter could be eligible for recovery through typical cost recovery processes of our electric utility business. The potential cost recovery would be subject to regulatory approval. Other Contingencies. We are party to litigation and regulatory matters arising in the normal course of business. We regularly analyze relevant information and, as necessary, estimate and record accrued liabilities for legal, regulatory enforcement and other 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 September 30, 2021, other than those discussed above, will not be material. |

Stockholders' Equity | Stockholders' Equity Registration Statements On May 3, 2021 we filed a shelf registration statement with the Securities and Exchange Commission (SEC) under which we may offer for sale, from time to time, either separately or together in any combination, equity, debt or other securities described in the shelf registration statement. The registration statement expires in May 2024. On May 3, 2021, we filed a second registration statement with the SEC for the issuance of up to 1,500,000 common shares under an Automatic Dividend Reinvestment and Share Purchase Plan, which provides shareholders, retail customers of OTP and other interested investors a method of purchasing our common shares by reinvesting their dividends and/or making optional cash investments. Shares purchased under the plan may be new issue common shares or common shares purchased on the open market. The registration statement expires in May 2024. Dividend Restrictions Otter Tail Corporation is a holding company with no significant operations of its own. The primary source of funds for payments of dividends to our shareholders is from dividends paid or distributions made by our subsidiaries. As a result of certain statutory limitations or regulatory or financing agreements, restrictions could occur on the amount of distributions allowed to be made by our subsidiaries. Both the OTC Credit Agreement and OTP Credit Agreement contain restrictions on the payment of cash dividends upon a default or event of default, including failure to maintain certain financial covenants. As of September 30, 2021, we were in compliance with these financial covenants. Under the Federal Power Act, a public utility may not pay dividends from any funds properly included in a capital account. What constitutes “funds properly included in a capital account” is undefined in the Federal Power Act or the related regulations; however, the FERC has consistently interpreted the provision to allow dividends to be paid as long as i) the source of the dividends is clearly disclosed, ii) the dividend is not excessive and iii) there is no self-dealing on the part of corporate officials. |

Share-Based Payments | Share-Based Payments Stock Compensation Expense Stock-based compensation expense arising from our employee stock purchase plan and share-based compensation plans, recognized within operating expenses in the consolidated statements of income, amounted to $0.8 million and $1.3 million for the three months ended September 30, 2021 and 2020, respectively, and $6.4 million and $5.3 million for the nine months ended September 30, 2021 and 2020, respectively. Stock Awards. We grant restricted stock awards to members of our Board of Directors and restricted stock units to our employees. The awards vest, depending on award type and recipient, either ratably over periods of three The grant date fair value of each stock award is determined based on the market price of our common stock on the date of grant adjusted to exclude the value of dividends for those awards that do not receive dividend or dividend equivalent payments during the vesting period. The following is a summary of stock award activity for the nine months ended September 30, 2021: Shares Weighted Average Nonvested, January 1, 2021 128,664 $ 44.30 Granted 57,650 43.10 Vested (47,646) 42.98 Forfeited (2,075) 40.95 Nonvested, September 30, 2021 136,593 $ 44.30 The fair value of vested awards was $2.1 million and $2.8 million during the nine months ended September 30, 2021 and 2020. Stock Performance Awards. Stock performance awards are granted to executive officers and certain other key employees. The awards vest at the end of a three-year performance period. The number of common shares awarded, if any, at the end of the performance period ranges from zero to 150% of the target amount based on two performance measures: i) total shareholder return relative to a peer group and ii) return on equity. The awards have no voting or dividend rights during the vesting period. Vesting of the awards is accelerated in certain circumstances, including on retirement. The amount of common shares awarded on an accelerated vesting is based either on actual performance at the end of the performance period or the amount of common shares earned at target. The grant date fair value of stock performance awards granted during the nine months ended September 30, 2021 and 2020 was determined using a Monte Carlo fair value simulation model incorporating the following assumptions: 2021 2020 Risk-free interest rate 0.18 % 1.42 % Expected term (in years) 3.00 3.00 Expected volatility 32.00 % 19.00 % Dividend yield 3.60 % 2.80 % The risk-free interest rate was derived from yields on U.S. government bonds of a similar term. The expected term of the award is equal to the three-year performance period. Expected volatility was estimated based on actual historical volatility of our common stock. Dividend yield was estimated based on historic and future yield estimates. The following is a summary of stock performance award activity for the nine months ended September 30, 2021 (share amounts reflect awards at target): Shares Weighted Average Nonvested, January 1, 2021 164,600 $ 42.32 Granted 79,000 38.34 Vested (54,000) 35.73 Forfeited — — Nonvested, September 30, 2021 189,600 $ 42.54 |

Earnings Per Share [Abstract] | |
Earnings Per Share | Earnings Per ShareThe numerator used in the calculation of both basic and diluted earnings per common share is net income. The denominator used in the calculation of basic earnings per common share is the weighted average number of common shares outstanding during the period. The denominator used in the calculation of diluted earnings per common share is derived by adjusting basic shares outstanding for the dilutive effect of potential common shares outstanding, which consist of time and performance based stock awards and employee stock purchase plan shares. The following includes the computation of the denominator for basic and diluted weighted-average shares outstanding for the three and nine months ended September 30, 2021 and 2020: Three Months Ended September 30, Nine Months Ended September 30, (in thousands) 2021 2020 2021 2020 Weighted Average Common Shares Outstanding – Basic 41,504 40,914 41,487 40,548 Effect of Dilutive Securities: Stock Performance Awards 262 98 209 107 Stock Awards 88 49 82 53 Employee Stock Purchase Plan Shares and Other 15 17 17 25 Dilutive Effect of Potential Common Shares 365 164 308 185 Weighted Average Common Shares Outstanding – Diluted 41,869 41,078 41,795 40,733 The amount of shares excluded from diluted weighted-average common shares outstanding because such shares were anti-dilutive was not material for the three and nine months ended September 30, 2021 and 2020. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Instruments | Derivative Instruments OTP enters into derivative instruments to manage its exposure to future price variability and reduce volatility in prices for our retail customers. These derivative instruments are not designated as qualifying hedging transactions but provide for an economic hedge against future price variability. The instruments are recorded at fair value on the consolidated balance sheets, with changes in fair value recorded in the consolidated statements of income. However, in accordance with rate-making and cost recovery processes, we recognize a regulatory asset or liability to defer losses or gains from derivative activity until settlement of the associated derivative instrument. As of September 30, 2021, OTP had outstanding pay-fixed, receive-variable swap agreements with an aggregate notional amount of 356,200 megawatt-hours of electricity, which will be settled periodically through 2022. As of September 30, 2021, the aggregate fair value of these contracts was $6.9 million, of which $6.1 million is included in other current assets and $0.8 million is included in other noncurrent assets on the consolidated balance sheets. |

Fair Value Measurements | Fair Value Measurements The following tables present our assets measured at fair value on a recurring basis as of September 30, 2021 and December 31, 2020 classified by the input method used to measure fair value: Level 1 Level 2 Level 3 September 30, 2021 Investments: Money Market Funds $ 953 $ — $ — Mutual Funds 5,170 — — Corporate Debt Securities — 2,377 — Government-Backed and Government-Sponsored Enterprises’ Debt Securities — 6,831 — Derivative Instruments — 6,923 — Total Assets $ 6,123 $ 16,131 $ — December 31, 2020 Investments: Money Market Funds $ 4,075 $ — $ — Mutual Funds 1,662 — — Corporate Debt Securities — 2,627 — Government-Backed and Government-Sponsored Enterprises’ Debt Securities — 6,633 — Total Assets $ 5,737 $ 9,260 $ — The level 2 fair value measurements for government-backed and government-sponsored enterprises and corporate debt securities are determined on the basis of valuations provided by a third-party pricing service which utilizes industry accepted valuation models and observable market inputs to determine valuation. Some valuations or model inputs used by the pricing service may be based on broker quotes. The level 2 fair value measurements for derivative instruments are determined by using inputs such as forward electric commodity prices, adjusted for location differences. These inputs are observable in the marketplace throughout the full term of the instrument, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace. In addition to assets recorded at fair value on a recurring basis, we also hold financial instruments that are not recorded at fair value in the consolidated balance sheets but for which disclosure of the fair value of these financial instruments is provided. The following reflects the carrying value and estimated fair value of these assets and liabilities as of September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 (in thousands) Carrying Fair Value Carrying Fair Value Assets: Cash and Cash Equivalents $ 1,272 $ 1,272 $ 1,163 $ 1,163 Total 1,272 1,272 1,163 1,163 Liabilities: Short-Term Debt 97,857 97,857 80,997 80,997 Long-Term Debt 764,581 873,632 764,519 858,455 Total $ 862,438 $ 971,489 $ 845,516 $ 939,452 The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash Equivalents: The carrying amount approximates fair value because of the short-term maturity of those instruments. Short-Term Debt: The carrying amount approximates fair value because the debt obligations are short-term and the balances outstanding are subject to variable rates of interest which reset frequently, a Level 2 fair value input. Long-Term Debt: The fair value of long-term debt is estimated based on current market indications for borrowings of similar maturities, a Level 2 fair value input. |
