Description of Organization and Business Operations	Note 1—Description of Organization and Business Operations Organization and General Kayne Anderson Acquisition Corp. (the “Company”) was incorporated in Delaware on December 12, 2016. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Initial Business Combination”). The Company’s focus is to search for a target business in the energy industry. The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, or the “Securities Act,” as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). On April 4, 2017, the Company closed its initial public offering (“Public Offering”) (See Note 3 and Note 6). The Company will not generate any operating revenues until after completion of its Initial Business Combination, at the earliest. The Company will generate non-operating Sponsor The Company’s sponsor is Kayne Anderson Sponsor, LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Public Offering (as described in Note 3) was declared effective by the United States Securities and Exchange Commission (the “SEC”) on March 29, 2017. The Trust Account The proceeds held in the trust account with American Stock Transfer & Trust Company, LLC acting as trustee (the “Trust Account”) are invested in money market funds that meet certain conditions under Rule 2a-7 The Company’s amended and restated certificate of incorporation provides that, other than the withdrawal of interest to pay taxes, if any, none of the funds held in the Trust Account will be released until the earlier of: (i) the completion of the Initial Business Combination; (ii) the redemption of any shares of Class A Common Stock included in the units (the “Public Shares”) sold in the Public Offering that have been properly tendered in connection with a stockholder vote to amend the Company’s certificate of incorporation to modify the substance or timing of its obligation to redeem 100% of such shares of Class A Common Stock if it does not complete the Initial Business Combination within 24 months from the closing of the Public Offering; and (iii) the redemption of 100% of the shares of Class A Common Stock included in the Units sold in the Public Offering if the Company is unable to complete an Initial Business Combination within 24 months from the closing of the Public Offering (subject to the requirements of law). The proceeds deposited in the Trust Account could become subject to the claims of the Company’s creditors, if any, which could have priority over the claims of the Company’s public stockholders. Initial Business Combination The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Public Offering, although substantially all of the net proceeds of the Public Offering are intended to be generally applied toward consummating an Initial Business Combination. The Initial Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the agreement to enter into the Initial Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect an Initial Business Combination. The Company, after signing a definitive agreement for an Initial Business Combination, will either (i) seek stockholder approval of the Initial Business Combination at a meeting called for such purpose in connection with which stockholders may seek to redeem their shares, regardless of whether they vote for or against the Initial Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable, or (ii) provide stockholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a stockholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable. The decision as to whether the Company will seek stockholder approval of the Initial Business Combination or will allow stockholders to sell their Public Shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek stockholder approval, unless a vote is required by law or under rules of The Nasdaq Stock Market. If the Company seeks stockholder approval, it will complete its Initial Business Combination only if a majority of the outstanding shares of common stock voted are voted in favor of the Initial Business Combination. However, in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001 upon consummation of the Initial Business Combination. In such case, the Company would not proceed with the redemption of its Public Shares and the related Initial Business Combination, and instead may search for an alternate Initial Business Combination. If the Company holds a stockholder vote or there is a tender offer for shares in connection with an Initial Business Combination, a public stockholder will have the right to redeem its shares for an amount in cash equal to its pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the Initial Business Combination, including interest but less taxes payable. As a result, such shares of Class A Common Stock will be recorded at redemption amount and classified as temporary equity upon the completion of the Public Offering, in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 480, “Distinguishing Liabilities from Equity.” Pursuant to the Company’s amended and restated certificate of incorporation, if the Company is unable to complete the Initial Business Combination within 24 months from the closing of the Public Offering, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, subject to lawfully available funds therefor, redeem the Public Shares, at a per-share In the event of a liquidation, dissolution or winding up of the Company after an Initial Business Combination, the Company’s stockholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of stock, if any, having preference over the common stock. The Company’s stockholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the common stock, except that the Company will provide its stockholders with the opportunity to redeem their Public Shares for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account, upon the completion of the Initial Business Combination, subject to the limitations described herein.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2—Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (“SEC”). In connection with the Company’s assessment of going concern considerations in accordance with ASU 2014-15, Emerging Growth Company Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities and Exchange Act of 1934, as amended, or the “Exchange Act”) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Net Income (Loss) Per Common Share Net income (loss) per common share is computed by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period, plus, to the extent dilutive, the incremental number of shares of common stock to settle warrants, as calculated using the treasury stock method. An aggregate of 36,026,954 shares of Class A common stock subject to possible redemption at December 31, 2017 have been excluded from the calculation of basic income per common share. The Company has not considered the effect of the warrants sold in the Public Offering (including the consummation of the over-allotment) and Private Placement Warrants to purchase 18,941,651 shares of the Company’s Class A common stock in the calculation of diluted income per share, since the exercise of the warrants and the conversion of the rights into shares of common stock is contingent upon the occurrence of future events and their inclusion would be antidilutive. At December 31, 2016, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company under the treasury stock method. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under the FASB ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the financial statements. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Deferred Offering Costs The Company complies with the requirements of the FASB ASC 340-10-S99-1 Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. To the extent a tax position does not meet these recognition and measurement thresholds, the associated benefit is not recognized in whole or in part and is reflected as an unrecognized tax benefit. There were no unrecognized tax benefits as of December 31, 2017 or 2016. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at December 31, 2017 or 2016. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its tax position. The Company is subject to income tax examinations by major taxing authorities since inception. During the year ended December 31, 2017, the Company recorded income tax expense of $695,876 and no income tax expense was recorded for year ended December 31, 2016. Until the Company completes an Initial Business Combination, its general and administrative expenses will be deferred for tax purposes but any interest income on the Trust Account net of franchises taxes will result in taxable income. During the year ended December 31, 2017, the Company made an estimated federal income tax payment of $391,000 resulting in an income tax liability of $304,876. Current Tax Liability $ (304,876 ) Deferred Tax Asset: Deferred general and administrative expenses $ 322,965 Valuation allowance at 21% (322,965 ) Deferred Tax Asset, net $ — At December 31, 2017, the Company had $1,537,927 of deferred general and administrative expenses resulting in a deferred tax asset of $322,965. Management has determined that a full valuation allowance on the deferred tax asset is appropriate at this time after consideration of all available positive and negative evidence related to the realization of the deferred tax asset. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Reform Bill”) was signed into law. Prior to the enactment of the Tax Reform Bill, the Company measured its deferred tax assets at the federal rate of 34%. The Tax Reform Bill reduced the federal tax rate to 21% resulting in the re-measurement The Company’s federal statutory income tax rate is 34% and the effective tax rate for the year ended December 31, 2017 was 137% which is a result of the full valuation allowance against its deferred tax asset. The total income taxes were different from the amount computed by applying the federal statutory income tax rate of 34% to income before income taxes as follows: Year Ended December 31, 2017 Computed federal income tax expense at 34% $ (172,891 ) Valuation allowance at 34% (522,985 ) Total income tax (expense) $ (695,876 ) Recent Accounting Pronouncements The Company’s management does not believe any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.

Public Offering	Note 3—Public Offering In April 2017, the Company closed its Public Offering of 37,732,112 units at a price of $10.00 per unit (the “Units”), with gross proceeds of $377,321,120 from the sale of Units. The closings occurred on April 4, 2017 with respect to 35,000,000 Units and on April 21, 2017 with respect to 2,732,112 Units related to the partial exercise of the underwriters’ over-allotment option. Each Unit consists of one share of the Company’s Class A Common Stock, and one-third 30-trading Commencing on April 27, 2017, the holders of Units issued in its Public Offering may elect to separately trade shares of Class A Common Stock and Warrants included in the Units. The Units not separated will continue to trade on The Nasdaq Capital Market under the symbol “KAACU.” Shares of Class A Common Stock and the Warrants are trading on The Nasdaq Capital Market under the symbols “KAAC” and “KAACW,” respectively. No fractional warrants will be issued upon separation of the Units and only whole Warrants will trade. The Company paid an underwriting discount of 2.0% of the per Unit offering price (or $7,546,422) to the underwriters at the closing of the Public Offering, with an additional fee (the “Deferred Discount”) of 3.5% of the gross offering proceeds (or $13,206,239) payable upon the Company’s completion of an Initial Business Combination. The Deferred Discount will become payable to the underwriters from the amounts held in the Trust Account solely in the event the Company completes its Initial Business Combination. The Company granted the underwriters a 45-day

Related Party Transactions [Abstract]
Related Party Transactions	Note 4—Related Party Transactions Founder Shares During December 2016, the Sponsor purchased 10,062,500 shares of Class B Common Stock (the “Founder Shares”) for an aggregate price of $25,000, or approximately $0.002 per share. During the year ended December 31, 2017, the Sponsor transferred 40,000 Founder Shares to each of the Company’s three independent directors (or an aggregate of 120,000 Founder Shares) at their original purchase price. As used herein, unless the context otherwise requires, Founder Shares shall be deemed to include the shares of Class A Common Stock issuable upon conversion thereof. The Founder Shares are identical to the Class A common stock included in the Units sold in the Public Offering except that the Founder Shares automatically convert into shares of Class A Common Stock at the time of the Company’s Initial Business Combination and are subject to certain transfer restrictions, as described in more detail below. Holders of Founder Shares may also elect to convert their shares of Class B Common Stock into an equal number of shares of Class A Common Stock, subject to adjustment as provided above, at any time. Prior to the Public Offering, the Sponsor agreed to forfeit up to 1,312,500 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters. The forfeiture was to be adjusted to the extent that the over-allotment option was not exercised in full by the underwriters so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding shares after the Public Offering. On April 21, 2017, as a result of the partial exercise of the over-allotment option, the Sponsor forfeited 629,472 of its Founder Shares. The Company’s initial stockholders agreed subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (A) one year after the completion of the Initial Business Combination or (B) subsequent to the Initial Business Combination, (x) if the last sale price of the Company’s Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading Private Placement Warrants Upon the closing of the Public Offering on April 4, 2017 and April 21, 2017, the Sponsor purchased an aggregate of 6,364,281 warrants at a price of $1.50 per warrant in a private placement (the “Private Placement Warrants”) (includes 364,281 warrants related to the Over-Allotment Units exercised) at a price of $1.50 per whole warrant ($9,546,422 in the aggregate) in a private placement. Each whole Private Placement Warrant is exercisable for one whole share of the Company’s Class A Common Stock at a price of $11.50 per share. A portion of the purchase price of the Private Placement Warrants was added to the proceeds from the Public Offering to be held in the Trust Account. If the Initial Business Combination is not completed within 24 months from the closing of the Public Offering, the proceeds from the sale of the Private Placement Warrants held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the Initial Business Combination. Registration Rights The holders of Founder Shares, Private Placement Warrants and Warrants that may be issued upon conversion of working capital loans, if any, are entitled to registration rights (in the case of the Founder Shares, only after conversion of such shares to shares of Class A Common Stock) pursuant to a registration rights agreement. These holders will be entitled to certain demand and “piggyback” registration rights. The holders of Founder Shares, Private Placement Warrants and Warrants that may be issued upon conversion of working capital loans will not be able to sell these securities until the termination of the applicable lock-up Related Party Loans On December 23, 2016, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Public Offering pursuant to a promissory note (the “Note”). On April 4, 2017, upon completion of the Public Offering, the Company paid in full the aggregate $265,000 of borrowings under the Note. At December 31, 2017 there were no outstanding related party loans. At December 31, 2016, the Company had $20,000 borrowed under the Note. Please see Note 7 —Subsequent Events. Administrative Support Agreement Beginning April, 2017, the Company agreed to pay an affiliate of the Sponsor a total of $5,000 per month for office space, utilities and secretarial and administrative support. Upon completion of the Initial Business Combination or the Company’s liquidation, the Company will cease paying these monthly fees. The Company incurred $45,000 for such services for the year ended December 31, 2017. Effective January 1, 2018, the Sponsor’s affiliate agreed to waive the monthly fee until the termination of the Company’s Administrative Service Agreement.

Fair Value Measurements	Note 6—Fair Value Measurements The following table presents information about the Company’s assets that are measured on a recurring basis as of December 31, 2017 and indicates the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable, such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and includes situations where there is little, if any, market activity for the asset or liability. As of December 31, 2016, the Company did not have any assets measured at fair value.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the accounting and disclosure rules and regulations of the Securities and Exchange Commission (“SEC”). In connection with the Company’s assessment of going concern considerations in accordance with ASU 2014-15,
Emerging Growth Company	Emerging Growth Company Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities and Exchange Act of 1934, as amended, or the “Exchange Act”) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.
Net Income (Loss) Per Common Share	Net Income (Loss) Per Common Share Net income (loss) per common share is computed by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period, plus, to the extent dilutive, the incremental number of shares of common stock to settle warrants, as calculated using the treasury stock method. An aggregate of 36,026,954 shares of Class A common stock subject to possible redemption at December 31, 2017 have been excluded from the calculation of basic income per common share. The Company has not considered the effect of the warrants sold in the Public Offering (including the consummation of the over-allotment) and Private Placement Warrants to purchase 18,941,651 shares of the Company’s Class A common stock in the calculation of diluted income per share, since the exercise of the warrants and the conversion of the rights into shares of common stock is contingent upon the occurrence of future events and their inclusion would be antidilutive. At December 31, 2016, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common stock and then share in the earnings of the Company under the treasury stock method.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.
Financial Instruments	Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under the FASB ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the financial statements.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Deferred Offering Costs	Deferred Offering Costs The Company complies with the requirements of the FASB ASC 340-10-S99-1
Income Taxes	Income Taxes The Company follows the asset and liability method of accounting for income taxes under FASB ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. To the extent a tax position does not meet these recognition and measurement thresholds, the associated benefit is not recognized in whole or in part and is reflected as an unrecognized tax benefit. There were no unrecognized tax benefits as of December 31, 2017 or 2016. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties at December 31, 2017 or 2016. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its tax position. The Company is subject to income tax examinations by major taxing authorities since inception. During the year ended December 31, 2017, the Company recorded income tax expense of $695,876 and no income tax expense was recorded for year ended December 31, 2016. Until the Company completes an Initial Business Combination, its general and administrative expenses will be deferred for tax purposes but any interest income on the Trust Account net of franchises taxes will result in taxable income. During the year ended December 31, 2017, the Company made an estimated federal income tax payment of $391,000 resulting in an income tax liability of $304,876. Current Tax Liability $ (304,876 ) Deferred Tax Asset: Deferred general and administrative expenses $ 322,965 Valuation allowance at 21% (322,965 ) Deferred Tax Asset, net $ — At December 31, 2017, the Company had $1,537,927 of deferred general and administrative expenses resulting in a deferred tax asset of $322,965. Management has determined that a full valuation allowance on the deferred tax asset is appropriate at this time after consideration of all available positive and negative evidence related to the realization of the deferred tax asset. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Reform Bill”) was signed into law. Prior to the enactment of the Tax Reform Bill, the Company measured its deferred tax assets at the federal rate of 34%. The Tax Reform Bill reduced the federal tax rate to 21% resulting in the re-measurement The Company’s federal statutory income tax rate is 34% and the effective tax rate for the year ended December 31, 2017 was 137% which is a result of the full valuation allowance against its deferred tax asset. The total income taxes were different from the amount computed by applying the federal statutory income tax rate of 34% to income before income taxes as follows: Year Ended December 31, 2017 Computed federal income tax expense at 34% $ (172,891 ) Valuation allowance at 34% (522,985 ) Total income tax (expense) $ (695,876 )
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company’s management does not believe any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.
