Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Overview Otter Tail Corporation (OTC) 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 polyvinyl chloride (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, 2021. Because of the seasonality of our businesses and other factors, the earnings for the three and six months ended June 30, 2022 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. Reclassifications Certain reclassifications of amounts previously reported have been made to the accompanying consolidated statements of shareholders' equity and consolidated statements of cash flows to maintain consistency and comparability between periods presented. The reclassifications had no impact on previously reported shareholders' equity, net cash provided by operating activities, net cash used in investing activities, net cash (used in) provided by financing activities, or cash and cash equivalents. |

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 six months ended June 30, 2022 and 2021 are as follows: Three Months Ended June 30, Six Months Ended June 30, (in thousands) 2022 2021 2022 2021 Operating Revenue Electric $ 130,949 $ 106,155 $ 261,365 $ 229,855 Manufacturing 103,196 84,284 208,154 160,107 Plastics 165,895 95,169 305,425 157,356 Total $ 400,040 $ 285,608 $ 774,944 $ 547,318 Net Income (Loss) Electric $ 18,858 $ 15,433 $ 38,091 $ 33,019 Manufacturing 7,555 5,705 11,639 11,089 Plastics 63,959 22,544 114,806 31,692 Corporate (4,435) (1,613) (6,596) (3,402) Total $ 85,937 $ 42,069 $ 157,940 $ 72,398 The following provides the identifiable assets by segment and corporate assets as of June 30, 2022 and December 31, 2021: (in thousands) June 30, December 31, Identifiable Assets Electric $ 2,309,245 $ 2,283,776 Manufacturing 267,050 251,044 Plastics 201,724 162,565 Corporate 97,481 57,445 Total $ 2,875,500 $ 2,754,830 |

Minnesota Rate Case On November 2, 2020, OTP filed an initial request with the MPUC for an increase in revenue recoverable through base rates in Minnesota, and on December 3, 2020, the MPUC approved an interim annual rate increase of $6.9 million, or 3.2%, effective January 1, 2021. On February 1, 2022, the MPUC issued its written order on final rates. The key provisions of the order included a revenue requirement of $209.0 million, based on a return on rate base of 7.18% and an allowed return on equity of 9.48% on an equity ratio of 52.5%. The order also authorized recovery of our remaining Hoot Lake Plant net asset over a five-year period and approved the requested decoupling mechanism for most residential and commercial customer rate groups with a cap of 4% of annual base revenues. On May 12, 2022, OTP's final rate case compliance filing was approved by the MPUC. The filing included final revenue calculations, rate design and resulting tariff revisions, along with a determination of the interim rate refund, which resulted in an increase in revenues during the second quarter of 2022 of $4.1 million. Final rates took effect on July 1, 2022, and we anticipate interim rate refunds will be applied to customer bills in the third quarter of 2022. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Commitments Ashtabula III Purchase. On June 23, 2022, OTP exercised its option to acquire the Ashtabula III wind farm, a 62.4 megawatt wind farm located in eastern North Dakota, for $49.7 million, subject to certain closing adjustments. Since 2013, OTP has purchased the wind-generated electricity from the Ashtabula III wind farm pursuant to a purchase power agreement, and that agreement granted OTP the option to purchase the wind farm. The purchase is subject to certain customary closing conditions and regulatory approval. We anticipate the transaction will close in January 2023. Contingencies FERC ROE. In November 2013 and February 2015, customers filed complaints with the Federal Energy Regulatory Commission (FERC) seeking to reduce the return on equity (ROE) component of the transmission rates that Midcontinent Independent System Operator, Inc. (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 $2.5 million as of June 30, 2022. 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 Environmental Protection Agency (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. The North Dakota Department of Environmental Quality (NDDEQ) has published a draft of its state implementation plan for public comment and held a public information session regarding the proposed plan. The draft plan concluded it is not reasonable to require additional emission controls during this planning period. The EPA has provided comments on the draft North Dakota state implementation plan in which it expressed disagreement with the NDDEQ's recommendation to forgo additional emission controls and has indicated that the current plan is not likely to be accepted. We anticipate the NDDEQ will file their proposed plan to the EPA for approval in August 2022. 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 the early retirement of or the sale of our interest in Coyote Station, subject to regulatory approval. We cannot estimate the ultimate 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 in rates 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 June 30, 2022, other than those discussed above, will not be material. |

Equity [Abstract] | |
Stockholders' Equity | Stockholders' Equity Registration Statements On May 3, 2021, we filed a shelf registration statement with the 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. No new debt or equity has been issued pursuant to the 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 a Share Purchase Plan, which provides shareholders, retail customers of OTP and other interested investors methods of purchasing our common shares, by reinvesting their dividends or making optional cash investments. Shares purchased under the plan may be newly issued common shares or common shares purchased on the open market. During the six months ended June 30, 2022, we issued 70,369 shares under this plan. We repurchased a sufficient number of shares on the open market to satisfy issuance under the plan; accordingly no proceeds from the issuance were received. As of June 30, 2022, there were 1,314,451 shares available for purchase or issuance under the plan. The registration statement expires in May 2024. Dividend Restrictions OTC 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, the amount of distributions allowed to be made by our subsidiaries or the amount of dividends paid by OTC could be restricted. 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 June 30, 2022, 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. |

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. 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 six months ended June 30, 2022 and 2021 was determined using a Monte Carlo fair value simulation model incorporating the following assumptions: 2022 2021 Risk-free interest rate 1.52 % 0.18 % Expected term (in years) 3.00 3.00 Expected volatility 32.00 % 32.00 % Dividend yield 2.90 % 3.60 % 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.

Earnings Per Share [Abstract] | |
Earnings Per Share | Earnings Per Share The 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 six months ended June 30, 2022 and 2021: Three Months Ended June 30, Six Months Ended June 30, (in thousands) 2022 2021 2022 2021 Weighted Average Common Shares Outstanding – Basic 41,597 41,500 41,573 41,478 Effect of Dilutive Securities: Stock Performance Awards 259 223 239 183 Restricted Stock Awards 85 75 94 80 Employee Stock Purchase Plan Shares and Other 3 20 1 18 Dilutive Effect of Potential Common Shares 347 318 334 281 Weighted Average Common Shares Outstanding – Diluted 41,944 41,818 41,907 41,759 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 six months ended June 30, 2022 and 2021. |

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. 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 June 30, 2022, OTP had outstanding pay-fixed, receive-variable swap agreements with an aggregate notional amount of 156,800 megawatt-hours of electricity, which will be settled periodically throughout 2022 and 2023. As of June 30, 2022, the fair value of these derivative instruments was $3.1 million, which is included in other current assets, $0.1 million, which is included in other current liabilities, and $0.2 million, which is included in other noncurrent liabilities, on the consolidated balance sheets. As of December 31, 2021, the fair value of these types of derivative contracts was $6.2 million, which is included in other current assets. During the six months ended June 30, 2022, contracts matured and were settled in an aggregate amount of $2.8 million. There were no contracts settled during the three or six months ended June 30, 2021, and no contracts settled during the three months ended June 30, 2022. |

Fair Value Measurements | Fair Value Measurements The following tables present our assets and liabilities measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021 classified by the input method used to measure fair value: (in thousands) Level 1 Level 2 Level 3 June 30, 2022 Assets: Investments: Money Market Funds $ 2,122 $ — $ — Mutual Funds 5,546 — — Corporate Debt Securities — 1,096 — Government-Backed and Government-Sponsored Enterprises’ Debt Securities — 7,255 — Derivative Instruments — 3,120 — Total Assets $ 7,668 $ 11,471 $ — Liabilities: Derivative Instruments $ — $ 326 $ — Total Liabilities $ — $ 326 $ — December 31, 2021 Assets: Investments: Money Market Funds $ 949 $ — $ — Mutual Funds 5,432 — — Corporate Debt Securities — 1,333 — Government-Backed and Government-Sponsored Enterprises’ Debt Securities — 7,869 — Derivative Instruments — 6,214 — Total Assets $ 6,381 $ 15,416 $ — Level 1 fair value measurements are based on quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. 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 June 30, 2022 and December 31, 2021: June 30, 2022 December 31, 2021 (in thousands) Carrying Fair Value Carrying Fair Value Assets: Cash and Cash Equivalents $ 61,989 $ 61,989 $ 1,537 $ 1,537 Total 61,989 61,989 1,537 1,537 Liabilities: Short-Term Debt — — 91,163 91,163 Long-Term Debt 853,695 767,700 763,997 878,272 Total $ 853,695 $ 767,700 $ 855,160 $ 969,435 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. |
