Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Principal Business and Organization | Principal Business and Organization FS Specialty Lending Fund, or the Company, was formed as a Delaware statutory trust under the Delaware Statutory Trust Act on September 16, 2010 and formally commenced investment operations on July 18, 2011. Prior to September 29, 2023, the Company’s name was FS Energy and Power Fund . The Company is an externally managed, non-diversified, closed-end management investment company that has elected to be regulated as a business development company, or BDC, under the Investment Company Act of 1940, as amended, or the 1940 Act. In addition, the Company has elected to be treated for U.S. federal income tax purposes, and intends to qualify annually, as a regulated investment company, or RIC, as defined under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code. As of December 31, 2023, the Company has various wholly-owned financing subsidiaries, including special-purpose financing subsidiaries and subsidiaries through which it holds or expects to hold interests in certain portfolio companies. The audited consolidated financial statements include both the Company’s accounts and the accounts of its wholly-owned subsidiaries as of December 31, 2023. All significant intercompany transactions have been eliminated in consolidation. Certain of the Company’s consolidated subsidiaries are subject to U.S. federal and state income taxes. On May 15, 2023, the Company announced that its board of trustees approved the Company’s transition from an investment policy of investing primarily in energy companies to a diversified credit investment policy of investing across private and public credit in a broader set of industries, sectors and sub-sectors. The Company notified its shareholders of the new policy, which became effective on September 29, 2023. The Company’s current investment objectives are to generate current income and, to a lesser extent, long-term capital appreciation by investing primarily in private and public credit in a broad set of industries, sectors and sub-sectors. The Company’s current investment policy is to invest primarily in a portfolio of secured and unsecured floating and fixed rate loans, bonds and other types of credit instruments, which, under normal circumstances, will represent at least 80% of the Company’s total assets. Prior to September 29, 2023, the Company’s investment objectives were to generate current income and long-term capital appreciation by investing primarily in privately-held U.S. companies in the energy and power industry. Prior to September 29, 2023, the Company’s investment policy was to invest, under normal circumstances, at least 80% of its total assets in securities of energy and power related, or Energy, companies. The Company considers Energy companies to be those companies that engage in the exploration, development, production, gathering, transportation, processing, storage, refining, distribution, mining, generation or marketing of natural gas, natural gas liquids, crude oil, refined products, coal or power, including those companies that provide equipment or services to companies engaged in any of the foregoing. The Company commenced transitioning the Company’s portfolio holdings away from Energy investments in May 2023, while remaining in compliance with the Company’s then-current investment policy. The Company’s allocation to Energy investments is expected to decline over time through the natural course of maturities, repayments and sales activity and by growing the total size of the portfolio through leverage facilities. The pace of the portfolio rotation is dependent upon a number of factors, including the turnover of concentrated illiquid Energy investments, performance of underlying portfolio companies, high yield and energy market conditions, the Company’s access to borrowings and the amount and pace of the payment of enhanced distributions to shareholders, among others. The Company is managed by FS/EIG Advisor, LLC, or FS/EIG Advisor, pursuant to an investment advisory and administrative services agreement, dated as of April 9, 2018, or the FS/EIG investment advisory agreement. FS/EIG Advisor oversees the management of the Company’s operations and is responsible for making investment decisions with respect to the Company’s portfolio. FS/EIG Advisor is jointly operated by an affiliate of Franklin Square Holdings, L.P. (which does business as FS Investments) and EIG Asset Management, LLC, or EIG. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation: The accompanying audited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The Company is considered an investment company under GAAP and follows the accounting and reporting guidance applicable to investment companies under Accounting Standards Codification Topic 946, Financial Services—Investment Companies . The Company has evaluated the impact of subsequent events through the date the consolidated financial statements were issued and filed with the Securities and Exchange Commission, or the SEC. Use of Estimates: The preparation of the audited consolidated financial statements in conformity with GAAP requires 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. Many of the amounts have been rounded, and all amounts are in thousands, except share and per share amounts. Cash and Cash Equivalents: The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company may invest its cash in a money market fund, which is stated at fair value. The Company's cash and cash equivalents are maintained with high credit quality financial institutions, which are members of the Federal Deposit Insurance Corporation. Valuation of Portfolio Investments: The Company’s board of trustees is responsible for overseeing the valuation of the Company’s portfolio investments at fair value as determined in good faith pursuant to FS/EIG Advisor’s valuation policy. As permitted by Rule 2a-5 of the 1940 Act, the Company’s board of trustees has designated FS/EIG Advisor as the Company’s valuation designee, with day-to-day responsibility for implementing the portfolio valuation process set forth in FS/EIG Advisor’s valuation policy. Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosure , or ASC Topic 820, issued by the FASB clarifies the definition of fair value and requires companies to expand their disclosure about the use of fair value to measure assets and liabilities in interim and annual periods subsequent to initial recognition. ASC Topic 820 defines fair value as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical securities; Level 2, which includes inputs such as quoted prices for similar securities in active markets and quoted prices for identical securities where there is little or no activity in the market; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. FS/EIG Advisor determines the fair value of the Company’s investment portfolio each quarter. Securities that are publicly-traded with readily available market prices will be valued at the reported closing price on the valuation date. Securities that are not publicly-traded with readily available market prices will be valued at fair value as determined in good faith by FS/EIG Advisor. In connection with that determination, FS/EIG Advisor will prepare portfolio company valuations which are based on relevant inputs, including, but not limited to, indicative dealer quotes, values of like securities, recent portfolio company financial statements and forecasts, and valuations prepared by independent third-party pricing and valuation services. With respect to investments for which market quotations are not readily available, a multi-step valuation process is undertaken each quarter, as described below: • the quarterly fair valuation process begins with FS/EIG Advisor facilitating the delivery of updated quarterly financial and other information relating to each investment to an independent third-party pricing or valuation service; • the independent third-party pricing or valuation service then reviews and analyzes the information, along with relevant market and economic data, and determines proposed valuations for each portfolio company or investment according to the valuation methodologies in FS/EIG Advisor’s valuation policy and communicates the information to FS/EIG Advisor in the form of a valuation range for Level 2 and Level 3 assets; • FS/EIG Advisor then reviews the preliminary valuation information for each portfolio company or investment and provides feedback about the accuracy, completeness and timeliness of the valuation-related inputs considered by the independent third-party pricing or valuation service and any suggested revisions thereto prior to the independent third-party pricing or valuation service finalizing its valuation range; • FS/EIG Advisor then provides the valuation committee with its valuation determinations and valuation-related information for each portfolio company or investment, along with any applicable supporting materials; and other information that is relevant to the fair valuation process; • the valuation committee meets with FS/EIG Advisor to receive the relevant quarterly reporting from FS/EIG Advisor and to discuss any questions from the valuation committee in connection with the valuation committee’s role in overseeing the fair valuation process; and • following the completion of its fair value oversight activities, the valuation committee (with the assistance of FS/EIG Advisor) provides the Company's board of trustees with a report regarding the quarterly valuation process. Determination of fair value involves subjective judgments and estimates. Accordingly, the notes to the Company's consolidated financial statements refer to the uncertainty with respect to the possible effect of such valuations and any change in such valuations on the Company's consolidated financial statements. In making its determination of fair value, FS/EIG Advisor may use any independent third-party pricing or valuation services for which it has performed the appropriate level of due diligence. However, FS/EIG Advisor is not required to determine fair value in accordance with the valuation provided by any single source, and may use any relevant data, including information sourced by FS/EIG Advisor or provided by any independent third-party pricing or valuation service that FS/EIG Advisor deems to be reliable in determining fair value under the circumstances. Below is a description of factors that FS/EIG Advisor and any independent third-party valuation services may consider when determining the fair value of the Company's investments. The valuation methods utilized for each portfolio company may vary depending on industry and company-specific considerations. Typically, the first step is to make an assessment as to the enterprise value of the portfolio company’s business in order to establish whether the portfolio company’s enterprise value is greater than the amount of its debt as of the valuation date. This analysis helps to determine a risk profile for the applicable portfolio company and its related investments, and the appropriate valuation methodology to utilize as part of the security valuation analysis. The enterprise valuation may be determined using a market or income approach. Valuation of fixed income investments, such as loans and debt securities, depends upon a number of factors, including prevailing interest rates for like securities, expected volatility in future interest rates, call features, put features and other relevant terms of the debt. For investments without readily available market prices, FS/EIG Advisor may incorporate these factors into discounted cash flow models to arrive at fair value. Various methods may be used to determine the appropriate discount rate in a discounted cash flow model. Other factors that may be considered include the borrower’s ability to adequately service its debt, the fair market value of the borrower in relation to the face amount of its outstanding debt and the quality of collateral securing the debt investments. For convertible debt securities, fair value generally approximates the fair value of the debt plus the fair value of an option to purchase the underlying security (i.e., the security into which the debt may convert) at the conversion price. To value such an option, a standard option pricing model may be used. The Company's equity interests in portfolio companies for which there is no liquid public market are valued at fair value. Generally, the value of the Company's equity interests in public companies for which market quotations are readily available is based upon the most recent closing public market price. When the Company receives warrants or other equity securities at nominal or no additional cost in connection with an investment in a debt security, the cost basis in the investment will be allocated between the debt securities and any such warrants or other equity securities received at the time of origination. FS/EIG Advisor subsequently values these warrants or other equity securities received at their fair value. Swap contracts typically are valued at their daily prices obtained from an independent third party. The aggregate settlement values and notional amounts of the swap contracts are not recorded in the consolidated financial statements. Fluctuations in the value of the swap contracts are recorded in the consolidated balance sheets as gross assets and gross liabilities and in the statements of operations as unrealized appreciation (depreciation) until closed, when they are recorded as net realized gain (loss). Revenue Recognition: Security transactions are accounted for on the trade date. The Company records interest income on an accrual basis to the extent that it expects to collect such amounts. The Company records dividend income on the ex-dividend date. Distributions received from limited liability company, or LLC, and limited partnership, or LP, investments are evaluated to determine if the distribution should be recorded as dividend income or a return of capital. The Company does not accrue as a receivable interest or dividends on loans and securities if it has reason to doubt its ability to collect such income. The Company's policy is to place investments on non-accrual status when there is reasonable doubt that interest income will be collected. The Company considers many factors relevant to an investment when placing it on or removing it from non-accrual status including, but not limited to, the delinquency status of the investment, economic and business conditions, the overall financial condition of the underlying investment, the value of the underlying collateral, bankruptcy status, if any, and any other facts or circumstances relevant to the investment. If there is reasonable doubt that the Company will receive any previously accrued interest, then the accrued interest will be written-off. Payments received on non-accrual investments may be recognized as income or applied to principal depending upon the collectability of the remaining principal and interest. Non-accrual investments may be restored to accrual status when principal and interest become current and are likely to remain current based on the Company's judgment. Loan origination fees, original issue discount and market discount are capitalized and the Company accretes such amounts as interest income over the respective term of the loan or security. Upon the prepayment of a loan or security, any unamortized loan origination fees and original issue discount are recorded as interest income. Structuring and other non-recurring upfront fees are recorded as fee income when earned. The Company records prepayment premiums on loans and securities as fee income when it earns such amounts. For the year ended December 31, 2023, the Company recognized $591 in structuring or other upfront fee revenue. For the years ended December 31, 2022 and 2021, the Company did not recognize any structuring or other upfront fee revenue. Net Realized Gains or Losses, Net Change in Unrealized Appreciation or Depreciation and Net Change in Unrealized Gains or Losses on Foreign Currency: Gains or losses on the sale of investments are calculated by using the specific identification method. The Company measures realized gains or losses by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment, without regard to unrealized appreciation or depreciation previously recognized, but considering unamortized fees. Net change in unrealized appreciation or depreciation reflects the change in portfolio investment values during the reporting period, including any reversal of previously recorded unrealized gains or losses when gains or losses are realized and the respective unrealized gain or loss on foreign currency for any foreign denominated investments it may hold. Net change in unrealized gains or losses on foreign currency reflects the change in the value of foreign currency held, receivables or accruals during the reporting period due to the impact of foreign currency fluctuations. Capital Gains Incentive Fee: Pursuant to the terms of the FS/EIG investment advisory agreement, the incentive fee on capital gains is determined and payable in arrears as of the end of each calendar year (or upon termination of such agreement). Such fee equals 20.0% of the Company’s “incentive fee capital gains,” which are the Company’s realized capital gains on a cumulative basis from inception, calculated as of the end of the applicable period, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid incentive fees on capital gains. The Company will accrue for the incentive fee on capital gains, which, if earned, will be paid annually. The Company will accrue the incentive fee on capital gains based on net realized and unrealized gains; however, the fee payable to FS/EIG Advisor will be based on realized gains and no such fee will be payable with respect to unrealized gains unless and until such gains are actually realized. Subordinated Income Incentive Fee: Pursuant to the terms of the FS/EIG investment advisory agreement, FS/EIG Advisor may also be entitled to receive a subordinated incentive fee on income. The subordinated incentive fee on income under the FS/EIG investment advisory agreement is calculated and payable quarterly in arrears and equals 20.0% of the Company’s “pre-incentive fee net investment income” for the immediately preceding quarter subject to a hurdle rate, expressed as a rate of return on adjusted capital, equal to 1.625% per quarter, or an annualized hurdle rate of 6.5%. As a result, FS/EIG Advisor will not earn this incentive fee for any quarter until the Company’s pre-incentive fee net investment income for such quarter exceeds the hurdle rate of 1.625%. For purposes of this fee, ‘‘adjusted capital’’ means cumulative gross proceeds generated from sales of the Company’s common shares (including proceeds from its distribution reinvestment plan) reduced for distributions from non-liquidating dispositions of the Company’s investments paid to shareholders and amounts paid for share repurchases pursuant to the Company’s share repurchase program. Once the Company’s pre-incentive fee net investment income in any quarter exceeds the hurdle rate, FS/EIG Advisor will be entitled to a “catch-up” fee equal to the amount of the Company’s pre-incentive fee net investment income in excess of the hurdle rate, until the Company’s pre-incentive fee net investment income for such quarter equals 2.031%, or 8.125% annually, of adjusted capital. This “catch-up” feature will allow FS/EIG Advisor to recoup the fees foregone as a result of the existence of the hurdle rate. Thereafter, FS/EIG Advisor will be entitled to receive 20.0% of the Company’s pre-incentive fee net investment income. Fixed Price Swaps : The Company may enter into fixed price swap contracts to economically hedge against the variability in cash flows associated with the sale of future crude oil and natural gas production. While the use of these derivative instruments limits the downside risk of adverse price movements, their use also limits future revenues from upward price movements. The Company's fixed price swaps are settled monthly based on differences between the fixed price specified in the contract and the referenced settlement price. When the referenced settlement price is less than the price specified in the contract, the Company receives an amount from the counterparty based on the price difference multiplied by the volume. Similarly, when the referenced settlement price exceeds the price specified in the contract, the Company pays the counterparty an amount based on the price difference multiplied by the volume. Total Return Swaps: The Company may enter into total return swaps to obtain exposure to a security or market without owning such security or investing directly in such market or to exchange the risk/return of one market with another market. Total return swaps are agreements in which there is an exchange of cash flows whereby one party agrees to make periodic payments based on the total return (distributions plus capital gains/losses) of an underlying instrument in exchange for fixed or floating rate interest payments. If the total return of the instrument or index underlying the transaction exceeds or falls short of the offsetting fixed or floating interest rate obligation, the Company receives payment from or makes a payment to the counterparty. Income Taxes: The Company has elected to be treated for U.S. federal income tax purposes, and intends to qualify annually, as a RIC under Subchapter M of the Code. To maintain qualification as a RIC and maintain RIC tax treatment, the Company must, among other things, meet certain source-of-income and asset diversification requirements, as well as distribute to its shareholders, in respect of each tax year, dividends of an amount generally at least equal to 90% of its "investment company taxable income," which is generally the Company's net ordinary income plus the excess, if any, of realized net short-term capital gains over realized net long-term capital losses, determined without regarding to any deduction for dividends paid. As a RIC, the Company will not have to pay corporate-level U.S. federal income taxes on any ordinary income or capital gains that it distributes as dividends to its shareholders. The Company intends to make distributions in an amount sufficient to qualify for and maintain its RIC tax treatment each tax year and to not pay any U.S. federal income taxes on income so distributed. The Company will also be subject to nondeductible U.S. federal excise taxes if it does not timely distribute dividends each calendar year of an amount at least equal to the sum of 98% of ordinary income (taking into account certain deferrals and elections) for the calendar year, 98.2% of any capital gain net income (adjusted for certain ordinary losses) for the one-year period ending on October 31 of such calendar year, and any recognized and undistributed ordinary income from prior years for which it paid no income taxes. Certain of the Company’s consolidated subsidiaries are subject to U.S. federal and state income taxes. Uncertainty in Income Taxes: The Company evaluates its tax positions to determine if the tax positions taken meet the minimum recognition threshold in connection with accounting for uncertainties in income tax positions taken or expected to be taken for the purposes of measuring and recognizing tax benefits or liabilities in the consolidated financial statements. Recognition of a tax benefit or liability with respect to an uncertain tax position is required only when the position is "more likely than not" to be sustained assuming examination by taxing authorities. The Company recognizes interest and penalties, if any, related to unrecognized tax liabilities as income tax expense in the consolidated statements of operations. During the years ended December 31, 2023, 2022 and 2021, the Company did not incur any interest or penalties. The Company has analyzed the tax positions taken on federal and state income tax returns for all open tax years, and has recorded a provision for taxes related to its wholly-owned taxable subsidiaries for the years ended December 31, 2023 and 2022 of $0 and $1,207, respectively. The Company's federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue. Distributions: Distributions to the Company's shareholders are recorded as of the record date. Subject to the discretion of the Company's board of trustees and applicable legal restrictions, the Company expects to declare and pay enhanced cash distributions on a quarterly basis. Net realized capital gains, if any, are distributed or deemed distributed at least annually. Reclassifications: Certain amounts in the consolidated financial statements for the years ended December 31, 2022 and 2021 may have been reclassified to conform to the classifications used to prepare the consolidated financial statements for the year ended December 31, 2023. Recent Accounting Pronouncements: In June 2022, the FASB issued Accounting Standards Update No. 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions , or ASU 2022-03, which clarifies guidance for fair value measurement of an equity security subject to a contractual sale restriction and establishes new disclosure requirements for such equity securities. ASU 2022-03 is effective for fiscal years beginning after December 15, 2023 and for interim periods within those fiscal years, with early adoption permitted. The Company has concluded that this guidance will not have a material impact on its consolidated financial statements. |

Share Transactions | Share Transactions Below is a summary of transactions with respect to the Company’s common shares during the years ended December 31, 2023, 2022 and 2021: Year Ended December 31, 2023 2022 2021 Shares Amount Shares Amount Shares Amount Reinvestment of Distributions (1) 4,040,482 $ 15,549 5,376,174 $ 20,861 6,069,376 $ 21,135 Proceeds from Share Transactions 4,040,482 $ 15,549 5,376,174 $ 20,861 6,069,376 $ 21,135 ______________ (1) On September 15, 2023, the Company's second amended and restated distribution reinvestment plan terminated. On July 19, 2023, the Company’s board of trustees, including the independent trustees, approved the termination of the Company’s second amended and restated distribution reinvestment plan with respect to distributions declared by the Company’s board of trustees on the Company’s common shares, effective as of September 15, 2023. After this date, all shareholders will receive any subsequent distributions in cash. On February 25, 2020, the Company received exemptive relief from the SEC permitting it to offer multiple classes of common shares. While the Company has no present intention to recommence a public offering of its common shares, the Company could do so in the future. Share Repurchase Program In March 2020, in light of difficult market conditions and in an effort to preserve liquidity in the Company, the Company’s board of trustees determined to suspend for an indefinite period of time the Company’s share repurchase program and will reassess the Company’s ability to recommence such program in future periods. Prior to its suspension, the Company intended to conduct quarterly tender offers pursuant to its share repurchase program. The Company's board of trustees will consider the following factors, among others, in making its determination regarding whether to cause the Company to offer to repurchase common shares and under what terms: • the effect of such repurchases on the Company’s qualification as a RIC (including the consequences of any necessary asset sales); • the liquidity of the Company's assets (including fees and costs associated with disposing of assets); • the Company’s investment plans and working capital requirements; • the relative economies of scale with respect to the Company’s size; • the Company’s history in repurchasing common shares or portions thereof; and • the condition of the securities markets. On May 5, 2017, the board of trustees of the Company further amended the share repurchase program. As amended, the Company limited the maximum number of common shares to be repurchased for any repurchase offer to the greater of (A) the number of common shares that the Company can repurchase with the proceeds it has received from the sale of common shares under its distribution reinvestment plan during the twelve-month period ending on the date the applicable repurchase offer expires (less the amount of proceeds used to repurchase common shares on each previous repurchase date for repurchase offers conducted during such twelve-month period) (this limitation is referred to as the twelve-month repurchase limitation) and (B) the number of common shares that the Company can repurchase with the proceeds the Company receives from the sale of common shares under its distribution reinvestment plan during the three-month period ending on the date the applicable repurchase offer expires (this limitation is referred to as the three-month repurchase limitation). In addition to this limitation, the maximum number of common shares to be repurchased for any repurchase offer has also been limited to 10% of the weighted average number of common shares outstanding in the prior calendar year, or 2.5% in each calendar quarter. As a result, the maximum number of common shares to be repurchased for any repurchase offer would not exceed the lesser of (i) 10% of the weighted average number of common shares outstanding in the prior calendar year, or 2.5% in each calendar quarter, and (ii) whichever is greater of the twelve-month repurchase limitation described in clause (A) above and the three-month repurchase limitation described in clause (B) above. Historically, pursuant to the Company's share repurchase program, the Company offered to repurchase common shares at a price equal to the price at which common shares were issued pursuant to the Company’s distribution reinvestment plan on the distribution date coinciding with the applicable share repurchase date. The price at which common shares were issued under the Company’s distribution reinvestment plan was determined by the Company’s board of trustees or a committee thereof, in its sole discretion, and was (i) not less than the net asset value per common share as determined in good faith by the Company’s board of trustees or a committee thereof, in its sole discretion, immediately prior to the payment date of the distribution and (ii) not more than 2.5% greater than the net asset value per common share as of such date. The Company’s board of trustees may amend, suspend or terminate the share repurchase program at any time, upon 30 days’ notice. The Company did not repurchase any shares pursuant to its share repurchase program during the years ended December 31, 2023, 2022 and 2021. The Company's distribution reinvestment plan was terminated effective September 15, 2023. In order to minimize the expense of supporting small accounts and provide additional liquidity to shareholders of the Company holding small accounts after completion of a regular quarterly share repurchase offer, the Company reserves the right to repurchase the shares of and liquidate any investor’s account if the balance of such account is less than the Company’s $5 minimum initial investment, unless the account balance has fallen below the minimum solely as a result of a decline in the Company’s net asset value per share. The Company will provide or will cause to be provided 30 days’ prior written notice to potentially affected investors, which notice may be included in regular quarterly repurchase offer materials, of any such repurchase. Historically, any such repurchases were made at the Company’s most recent price at which the Company’s shares were issued pursuant to its distribution reinvestment plan. There were no de minimis account liquidations during the years ended December 31, 2023, 2022 and 2021. |

Related Party Transactions | Related Party Transactions Compensation of the Investment Adviser Pursuant to the FS/EIG investment advisory agreement, FS/EIG Advisor is entitled to an annual base management fee based on the average weekly value of the Company’s gross assets (gross assets equals total assets as set forth on the Company’s consolidated balance sheets) during the most recently completed calendar quarter and an incentive fee based on the Company’s performance. The base management fee is payable quarterly in arrears, and is calculated at an annual rate of 1.75% of the average weekly value of the Company’s gross assets. See Note 2 for a discussion of the capital gains and subordinated income incentive fees that FS/EIG Advisor may be entitled to under the FS/EIG investment advisory agreement. During the years ended December 31, 2023, 2022 and 2021, there were no capital gains or subordinated income incentive fees accrued or paid to FS/EIG Advisor. FS/EIG Advisor may receive structuring or other upfront fees from portfolio companies in which FS/EIG Advisor has caused the Company to invest. FS/EIG Advisor has agreed to offset the amount of any structuring, upfront or certain other fees received by FS/EIG Advisor or its members against the management fees payable by the Company under the FS/EIG investment advisory agreement. During the years ended December 31, 2023, 2022 and 2021, $341, $2,619 and $1,439, respectively, of structuring, upfront or certain other fees received by FS/EIG Advisor or its members were offset against management fees. Pursuant to the FS/EIG investment advisory agreement, FS/EIG Advisor oversees the Company’s day-to-day operations, including the provision of general ledger accounting, fund accounting, legal services, investor relations, certain government and regulatory affairs activities and other administrative services. FS/EIG Advisor also performs, or oversees the performance of, the Company’s corporate operations and required administrative services, which includes being responsible for the financial records that the Company is required to maintain and preparing reports for the Company’s shareholders and reports filed with the SEC. The Company reimburses FS/EIG Advisor for expenses necessary to perform services related to the Company’s administration and operations, including FS/EIG Advisor’s allocable portion of the compensation and/or related expenses of certain personnel of FS Investments and EIG providing administrative services to the Company on behalf of FS/EIG Advisor, and for transactional expenses for prospective investments, such as fees and expenses associated with performing due diligence reviews of investments that do not close, often referred to as "broken deal" costs. The Company reimburses FS/EIG Advisor no less than quarterly for expenses necessary to perform services related to the Company’s administration and operations. The amount of this reimbursement is set at the lesser of (1) FS/EIG Advisor’s actual costs incurred in providing such services and (2) the amount that the Company estimates it would be required to pay alternative service providers for comparable services in the same geographic location. FS/EIG Advisor allocates the cost of such services to the Company based on factors such as time allocations and other reasonable metrics. The Company’s board of trustees reviews the methodology employed in determining how the expenses are allocated to the Company and assesses the reasonableness of such reimbursements for expenses allocated to the Company based on the breadth, depth and quality of such services as compared to the estimated cost to the Company of obtaining similar services from third-party providers known to be available. In addition, the Company’s board of trustees considers whether any single third-party service provider would be capable of providing all such services at comparable cost and quality. Finally, the Company’s board of trustees, among other things, compares the total amount paid to FS/EIG Advisor for such services as a percentage of the Company’s net assets to the same ratio as reported by other comparable BDCs. The Company does not reimburse FS/EIG Advisor for any services for which it receives a separate fee, or for rent, depreciation, utilities, capital equipment or other administrative items allocated to a controlling person of FS/EIG Advisor. The following table describes the fees and expenses accrued under the FS/EIG investment advisory agreement during the years ended December 31, 2023, 2022 and 2021: Year Ended December 31, Related Party Source Agreement Description 2023 2022 2021 FS/EIG Advisor FS/EIG investment advisory agreement Base Management Fee (1) $ 35,036 $ 41,940 $ 40,122 FS/EIG Advisor FS/EIG investment advisory agreement Administrative Services Expenses (2) $ 6,087 $ 5,626 $ 5,713 _________________________ (1) During the years ended December 31, 2023, 2022 and 2021, $37,805, $41,221 and $39,812, respectively, in base management fees were paid to FS/EIG Advisor. The base management fee amount shown in the table above for the years ended December 31, 2023, 2022 and 2021 is shown net of $341, $2,619 and $1,439, respectively, in structuring, upfront or certain other fees received by FS/EIG Advisor or its members and offset against base management fees. As of December 31, 2023, $8,416 in base management fees were payable to FS/EIG Advisor. (2) During the years ended December 31, 2023, 2022 and 2021, $4,431, $3,930 and $3,450, respectively, of the accrued administrative services expenses related to the allocation of costs of administrative personnel for services rendered to the Company by FS/EIG Advisor and the remainder related to other reimbursable expenses. The Company paid $6,469, $5,134 and $4,849 in administrative services expenses to FS/EIG Advisor, or its affiliates, during the years ended December 31, 2023, 2022 and 2021, respectively. Potential Conflicts of Interest The members of the senior management and investment teams of FS/EIG Advisor serve or may serve as officers, directors or principals of entities that operate in the same or a related line of business as the Company does, or of investment vehicles managed by the same personnel. The officers, managers and other personnel of FS/EIG Advisor may serve in similar or other capacities for the investment advisers to future investment vehicles affiliated with FS Investments or EIG. In serving in these multiple and other capacities, they may have obligations to other clients or investors in those entities, the fulfillment of which may not be in the Company’s best interests or in the best interest of the Company’s shareholders. The Company’s investment objectives may overlap with the investment objectives of such investment funds, accounts or other investment vehicles. Exemptive Relief |

Distributions | Distributions The following table reflects the cash distributions per share that the Company has declared on its common shares during the years ended December 31, 2023, 2022 and 2021: Distribution For the Year Ended December 31, Per Share Amount 2021 $ 0.1200 $ 53,264 2022 $ 0.1200 $ 53,938 2023 $ 0.1892 $ 86,059 Subject to applicable legal restrictions and the sole discretion of the Company's board of trustees, the Company expects to provide enhanced quarterly distributions to shareholders until the achievement of a long-term liquidity event. On October 18, 2023, the Company's board of trustees declared the initial enhanced cash distribution of $0.0683 per share for the quarter ended September 30, 2023. For the quarter ended December 31, 2023, the distribution amount per share was $0.0643, comprised of an initial distribution per share of $0.0609 declared in December 2023 and the remaining distribution per share of $0.0034 declared in January 2024, representing an annualized distribution rate to shareholders of 7.5% based on the net asset value of $3.43 per share as of December 31, 2023. The enhanced distributions are expected to be paid quarterly and increase in subsequent years until the achievement of a long-term liquidity event, subject to a maximum cap of 15.0% of the Company's then-current estimated net asset value beyond 2026. The Company expects a portion of the distributions may represent a return of investor capital, helping to accelerate liquidity for shareholders in the near-term. There can be no assurance that the Company will be able to pay distributions in the future. The timing and amount of any future distributions to shareholders are subject to applicable legal restrictions and the sole discretion of the Company's board of trustees. Historically, the Company had an “opt in” distribution reinvestment plan for its shareholders. As a result, if the Company made a cash distribution, its shareholders would receive distributions in cash unless they specifically “opted in” to the distribution reinvestment plan so as to have their cash distributions reinvested in additional common shares. However, certain state authorities or regulators may have imposed restrictions from time to time that may have prevented or limited a shareholder’s ability to participate in the distribution reinvestment plan. The Company's distribution reinvestment plan was terminated effective as of September 15, 2023. Under the prior distribution reinvestment plan, cash distributions to participating shareholders would be reinvested in additional common shares at a purchase price determined by the Company's board of trustees, or a committee thereof, in its sole discretion, that was (i) not less than the net asset value per common share as determined in good faith by the Company's board of trustees or a committee thereof, in its sole discretion, immediately prior to the payment of the distribution and (ii) not more than 2.5% greater than the net asset value per common share as of such date. Any distributions reinvested under the plan would remain taxable to a U.S. shareholder. The Company may fund its cash distributions to shareholders from any sources of funds legally available to it, including proceeds from the sale of the Company’s common shares, borrowings, net investment income from operations, capital gains proceeds from the sale of assets and non-capital gains proceeds from the sale of assets, dividends or other distributions paid to the Company on account of preferred and common equity investments in portfolio companies. The Company has not established limits on the amount of funds it may use from available sources to make distributions. The Company's distribution proceeds have exceeded and in the future may exceed its earnings. Therefore, portions of the distributions that the Company has made represented, and may make in the future may represent, a return of capital to shareholders, which lowers their tax basis in their common shares. A return of capital generally is a return of a shareholder’s investment rather than a return of earnings or gains derived from the Company’s investment activities. Each year a statement on Form 1099-DIV identifying the sources of the distributions (i.e., paid from ordinary income, paid from net capital gains on the sale of securities, and/or a return of capital, which is a nontaxable distribution) will be mailed to the Company’s shareholders. There can be no assurance that the Company will be able to pay distributions at a specific rate or at all. The following table reflects the sources of the cash distributions on a tax basis that the Company declared on its common shares during the years ended December 31, 2023, 2022 and 2021: Year Ended December 31, 2023 2022 2021 Source of Distribution Distribution Amount Percentage Distribution Amount Percentage Distribution Amount Percentage Net investment income (1) $ 86,059 100 % $ 53,938 100 % $ 53,264 100 % Short-term capital gains proceeds from the sale of assets — — — — — — Long-term capital gains proceeds from the sale of assets — — — — — — Return of capital — — — — — — Total $ 86,059 100 % $ 53,938 100 % $ 53,264 100 % ______________________________ (1) During the years ended December 31, 2023, 2022 and 2021, 87.1%, 85.5% and 74.1%, respectively, of the Company's gross investment income was attributable to cash income earned, 9.0%, 10.8% and 18.5%, respectively, was attributable to paid-in-kind, or PIK, interest and 3.9%, 3.7% and 7.4%, respectively, was attributable to non-cash accretion of discount. The Company’s net investment income on a tax basis for the years ended December 31, 2023, 2022 and 2021 was $101,804, $69,711 and $80,892, respectively. As of December 31, 2023 and 2022, the Company had $36,369 and $21,803, respectively, of undistributed ordinary income on a tax basis. The difference between the Company’s GAAP-basis net investment income and its tax-basis net investment income was primarily due to the reclassification of unamortized original issue discount, certain prepayment fees recognized upon prepayment of loans from income for GAAP purposes to realized gains for tax purposes, the impact of certain subsidiaries that are consolidated for purposes of computing GAAP-basis net investment income but are not consolidated for purposes of computing tax-basis net investment income and income recognized for GAAP purposes on certain transactions but not subject to tax or income recognized for tax purposes on certain transactions but not recognized for GAAP purposes. The Company’s undistributed net investment income on a tax basis may be adjusted following the filing of the Company’s tax returns. The following table sets forth a reconciliation between GAAP-basis net investment income and tax-basis net investment income during the years ended December 31, 2023, 2022 and 2021: Year Ended December 31, 2023 2022 2021 GAAP-basis net investment income $ 81,363 $ 69,769 $ 43,259 Reclassification of unamortized original issue discount and prepayment fees (5,072) (12,480) (4,030) GAAP vs. tax-basis impact of consolidation of certain subsidiaries 2,652 1,242 13,532 Income subject to tax not recorded for GAAP (income recorded for GAAP not subject to tax) 22,612 13,036 28,182 Other miscellaneous differences 249 (1,856) (51) Tax-basis net investment income $ 101,804 $ 69,711 $ 80,892 The Company may make certain adjustments to the classification of shareholders’ equity as a result of permanent book-to-tax differences. During the year ended December 31, 2023, the Company increased accumulated earnings (deficit) and reduced capital in excess of par value by $21,053. During the year ended December 31, 2022, the Company reduced accumulated earnings (deficit) and increased capital in excess of par value by $41,185. The determination of the tax attributes of the Company’s distributions is made annually as of the end of the Company’s fiscal year based upon the Company’s taxable income for the full year and distributions paid for the full year. Therefore, a determination made on a quarterly basis may not be representative of the actual tax attributes of the Company's distributions for a full year . The actual tax characteristics of distributions to shareholders are reported to shareholders annually on Form 1099-DIV. As of December 31, 2023 and 2022, the components of accumulated earnings on a tax basis were as follows: December 31, 2023 2022 Distributable ordinary income $ 36,369 $ 21,803 Accumulated capital losses (1) (1,595,362) (1,282,145) Other temporary differences (670) (83) Net unrealized appreciation (depreciation) on investments, swap contracts and foreign currency (2) (64,522) (177,571) Total $ (1,624,185) $ (1,437,996) ______________________________ (1) Net capital losses may be carried forward indefinitely, and their character is retained as short-term or long-term. As of December 31, 2023, the Company had short-term and long-term capital loss carryforwards available to offset future realized capital gains of $74,081 and $1,521,281, respectively. (2) As of December 31, 2023 and 2022, for federal income tax purposes, the gross unrealized appreciation on the Company's investments was $148,817 and $334,635, respectively, and the gross unrealized depreciation on the Company's investments, swap contracts and unrealized loss on foreign currency was $213,339 and $512,206, respectively. The aggregate cost of the Company's investments for federal income tax purposes totaled $1,587,709 and $2,223,943 as of December 31, 2023 and 2022, respectively. The aggregate net unrealized appreciation (depreciation) of the Company's investments on a tax basis was $(64,513) and $(176,828) as of December 31, 2023 and 2022, respectively. As of December 31, 2023 and 2022, the Company had deferred tax assets of $142,608 and $145,383, respectively, particularly resulting from interest expense disallowance, net operating losses and capital losses of the Company's wholly-owned taxable subsidiaries. As of December 31, 2023 and 2022, the Company had deferred tax liabilities of $2,595 and $28,753, respectively, resulting from unrealized appreciation on investments held by the Company's wholly-owned taxable subsidiaries. As of December 31, 2023 and 2022, certain wholly-owned taxable subsidiaries anticipated that they would be unable to fully utilize their deferred tax assets, therefore the deferred tax assets were offset by valuation allowances of $140,013 and of $116,630, respectively. For the year ended December 31, 2022, the Company recorded a provision for taxes related to its wholly-owned taxable subsidiaries of $1,207 related to current taxes. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Financial Instruments | The Company may trade in financial instruments with off-balance sheet risk in the normal course of its investing activities. During the years ended December 31, 2023 and 2022, the Company utilized commodity fixed price swaps to economically hedge certain risks against natural gas and crude oil price exposure related to certain investments in the Company's portfolio. During the year ended December 31, 2023, the Company entered into an equity total return swap to obtain exposure to a security without owning such security. During the year ended December 31, 2021, the Company did not utilize any swap contracts. While the use of these derivative instruments limits the downside risk of adverse price movements, their use also limits future revenues from upward price movements. Fixed Price Swaps A fixed price swap is a contract between two parties in which settlements are made at a specified time based on the difference between the fixed price specified in the contract and the referenced settlement price. When the referenced settlement price is less than the price specified in the contract, the Company receives an amount from the counterparty based on the price difference multiplied by the volume. Similarly, when the referenced settlement price exceeds the price specified in the contract, the Company pays the counterparty an amount based on the price difference multiplied by the volume. The Company's fixed price swaps are settled monthly and the settlement prices contained in these fixed price swaps are based on commodity exchanges; the NYMEX Henry Hub for natural gas and the ICE Brent for oil. Gas volumes are measured in one million British thermal units, or MMBtus, and oil volumes are measured in barrels, or Bbls. The changes in the value of the fixed price swaps are recorded as unrealized appreciation or depreciation on swap contracts in the consolidated balance sheets. The Company's fixed price swaps settle monthly and the changes in the value of the fixed price swaps are recorded as realized gains or losses in the consolidated statements of operations. The primary underlying risk exposure through the use of fixed price swaps is commodity price risk of the underlying commodity, such as natural gas and crude oil. As of December 31, 2023, the Company's fixed price swaps were fully terminated. Total Return Swaps A total return swap is a contract in which there is an exchange of cash flows whereby one party agrees to make periodic payments based on the total return (distributions plus capital gains/losses) of an underlying instrument in exchange for fixed or floating rate interest payments. If the total return of the instrument or index underlying the transaction exceeds or falls short of the offsetting fixed or floating interest rate obligation, the Company receives payment from or makes a payment to the counterparty. Total return swaps are entered into to obtain exposure to a security or market without owning such security or investing directly in such market or to exchange the risk/return of one market with another market. On September 20, 2023, the Company entered into an equity total return swap, or equity TRS, with Nomura Global Financial Products Inc., or Nomura. Under the equity TRS, the Company obtains the economic benefit of owning shares of FS Credit Opportunities Corp., or FSCO, an investment company registered under the 1940 Act, without actually owning them, and Nomura will receive an interest-type payment in return. The investment adviser to FSCO is wholly-owned by Franklin Square Holdings, L.P., which is also the majority owner of FS/EIG Advisor. The Company's equity TRS is marked-to-market daily and the change in market value is recorded as unrealized appreciation or depreciation on swap contracts in the consolidated balance sheets. Pursuant to its terms, the Company's equity TRS settles monthly and a realized gain or loss is recorded in the consolidated statements of operations equal to the difference between the value of the shares underlying the equity TRS at the time the swap was entered into or the previous settlement date and the value as of the current settlement date, plus dividends received and less accrued interest. Any dividends received by Nomura as holder of the FSCO shares are paid to the Company. The equity TRS has a term of three years, but it could be terminated earlier in whole or in part following the occurrence of certain prescribed events agreed to between Nomura and the Company. The primary underlying risk exposure through the use of equity total return swaps is equity market risk. During the years ended December 31, 2023 and 2022, the average monthly notional volume of fixed price swap contracts—crude oil and fixed price swap contracts—natural gas outstanding were 88,849 Bbls and 207,555 Bbls, respectively, and 169,313 MMBtus and 398,707 MMBtus, respectively. The average notional amount of the equity total return swap from the initial trade date of September 25, 2023 through December 31, 2023 was $19,939. The following table presents the fair value of swap contracts (which are not considered to be hedging instruments for accounting purposes) as of December 31, 2023 and 2022: December 31, 2023 December 31, 2022 Instrument Asset Liability Asset Liability (1) Commodity Fixed Price Swaps—Crude Oil $ — $ — $ — $ (572) Commodity Fixed Price Swaps—Natural Gas — — — (126) Equity Total Return Swaps — — — — Total $ — $ — $ — $ (698) ______________ (1) Reflected on the Company's consolidated balance sheets as: Unrealized depreciation on swap contracts.

(2) Reflected on the Company's consolidated statements of operations as: Net change in unrealized appreciation (depreciation) on swap contracts. Offsetting of Derivative Instruments The Company has derivative instruments that are subject to master netting agreements. These agreements include provisions to offset positions with the same counterparty in the event of default by one of the parties. The Company’s unrealized appreciation and depreciation on derivative instruments are reported as gross assets and liabilities, respectively, in the consolidated balance sheets. The following table presents the Company’s derivative assets and liabilities by counterparty, net of amounts available for offset under a master netting agreement as of December 31, 2022: As of December 31, 2022 Counterparty Derivative Assets Derivative Liabilities Net Value of Derivatives Non-Cash Collateral (Received) Pledged (1) Cash Collateral (Received) Pledged (1) Net Amount of Derivative Assets (Liabilities) (2) BP Energy Co. — $ (698) $ (698) — — $ (698) ______________ (1) In some instances, the actual amount of the collateral received and/or pledged may be more than the amount shown due to overcollateralization.

Sustainable Infrastructure Investments, LLC Sustainable Infrastructure Investments, LLC, or SIIJV, is a joint venture between the Company and Imperial Sustainable Infrastructure Investments, LLC, or Imperial, a subsidiary of Imperial Capital Asset Management, LLC, or ICAM. The joint venture is governed pursuant to the terms of an amended and restated limited liability company agreement of SIIJV, dated as of January 2, 2020, between the Company and Imperial, or the SIIJV Agreement. The SIIJV Agreement requires the Company and Imperial to provide capital to SIIJV of up to $67,629 in U.S. dollars and $5,430 in Canadian dollars in the aggregate where the Company and Imperial would provide 87.5% and 12.5%, respectively, of the committed capital. Pursuant to the terms of the SIIJV Agreement, the Company and Imperial each have 50% voting control of SIIJV and are required to agree on all investment decisions as well as all other significant actions for SIIJV. SIIJV invests in senior secured loans (both first lien and second lien) to middle market companies, broadly syndicated loans and other midstream, renewables and power assets. As administrative agent of SIIJV, the Company performs certain day-to-day management responsibilities on behalf of SIIJV and is entitled to a fee in the annual amount of 0.25% of SIIJV’s net assets under administration, calculated and payable quarterly in arrears. As of December 31, 2023, the Company and Imperial funded approximately $49,313 to SIIJV, of which $43,150 was from the Company. The Company does not consolidate SIIJV in its consolidated financial statements. On January 2, 2020, Seine Funding, LLC, or Seine Funding, a wholly-owned subsidiary of SIIJV, entered into a credit facility, as amended, or the Seine Funding Facility, with certain financial institutions as lender, agent, collateral agent, collateral administrator, and collateral custodian, and SIIJV, as collateral manager. The Seine Funding Facility provides for borrowings in U.S. dollars and certain agreed upon foreign currencies in an aggregate principal amount of up to $634,103 on a committed basis, which may be increased under certain circumstances at the request of Seine Funding and with the consent of the lender and agent. The end of the reinvestment period for the Seine Funding Facility was on December 31, 2020. The maturity date for the Seine Funding Facility is the earlier of (i) the latest maturity date among the assets securing the facility and (ii) the first date, after the end of the reinvestment period, on which all assets securing the facility are paid in full. Under the Seine Funding Facility, borrowings bear interest at the rate of Term SOFR plus a credit spread adjustment calculated by reference to the interest periods of particular loan assets per the terms of the credit agreement (or the relevant benchmark reference rate for any foreign currency borrowings) (in each case, subject to a floor of the higher of 0% and any applicable floor for particular loan assets), plus 1.20% per annum. Borrowings under the Seine Funding Facility are secured by a first priority security interest in substantially all of the assets of Seine Funding. As of December 31, 2023, total outstanding borrowings under the Seine Funding Facility were $145,483.

Fair Value Disclosures [Abstract] | |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Under existing accounting guidance, fair value is defined as the price that the Company would receive upon selling an investment or pay to transfer a liability in an orderly transaction to a market participant in the principal or most advantageous market for the investment. This accounting guidance emphasizes valuation techniques that maximize the use of observable market inputs and minimize the use of unobservable inputs. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs are inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances. The Company classifies the inputs used to measure these fair values into the following hierarchy as defined by current accounting guidance: Level 1: Inputs that are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs that are quoted prices for similar assets or liabilities in active markets. Level 3: Inputs that are unobservable for an asset or liability. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. As of December 31, 2023 and 2022, the Company’s investments were categorized as follows in the fair value hierarchy: Valuation Inputs December 31, 2023 December 31, 2022 Level 1—Price quotations in active markets $ — $ 2,465 Level 2—Significant other observable inputs 683,716 450,445 Level 3—Significant unobservable inputs 839,480 1,594,205 Total $ 1,523,196 $ 2,047,115 As of December 31, 2023 and 2022, the Company’s swap contracts were categorized as follows in the fair value hierarchy: December 31, 2023 December 31, 2022 Valuation Inputs Assets Liabilities Assets Liabilities Level 1—Price quotations in active markets $ — $ — $ — $ — Level 2—Significant other observable inputs — — — 698 Level 3—Significant unobservable inputs — — — — Total $ — $ — $ — $ 698 The Company’s board of trustees is responsible for overseeing the valuation of the Company’s portfolio investments at fair value as determined in good faith pursuant to FS/EIG Advisor’s valuation policy. The Company’s board of trustees has designated FS/EIG Advisor with day-to-day responsibility for implementing the portfolio valuation process set forth in FS/EIG Advisor’s valuation policy. The Company’s investments consist primarily of investments that were acquired directly from the issuer. Debt investments, for which broker quotes or pricing information from third-party pricing services are not generally available, are valued by FS/EIG Advisor with the assistance of independent valuation firms, which determine a valuation range of fair value for such investments by considering, among other factors, the borrower’s ability to adequately service its debt, prevailing interest rates for like investments, call features, anticipated prepayments and other relevant terms of the investments. Except as described below, the Company’s investment in SIIJV and all of the Company’s preferred equity and equity/other investments are also valued by independent valuation firms, which determine the fair value of such investments by considering, among other factors, contractual rights ascribed to such investments, as well as various income scenarios and multiples of earnings before interest, taxes, depreciation and amortization, or EBITDA, cash flows, net income, revenues or, in limited instances, book value, PV-10 multiples or liquidation value. An investment that is newly issued and purchased near the date of the financial statements is valued at cost if FS/EIG Advisor determines that the cost of such investment is the best indication of its fair value. Such investments described above are typically classified as Level 3 within the fair value hierarchy. Investments that are traded on an active public market are valued at their closing price as of the date of the financial statements and are classified as Level 1 within the fair value hierarchy. Except as described above, FS/EIG Advisor typically values the Company’s other investments by using the midpoint of the prevailing bid and ask prices from dealers on the date of the relevant period end, which are provided by an independent third-party pricing service and screened for validity by such service and are typically classified as Level 2 within the fair value hierarchy. In determining the fair values of fixed price swaps, FS/EIG Advisor utilizes an industry-standard pricing model that considers various inputs including quoted forward prices for commodities, time value and current market and contractual prices for the underlying instruments. The fair value of the equity total return swap is determined daily based on the market price of the underlying asset. These assumptions are observable in the marketplace or can be corroborated by active markets or broker quotes and are typically classified as Level 2 within the fair value hierarchy. FS/EIG Advisor periodically benchmarks the bid and ask prices it receives from the third-party pricing service and/or dealers and independent valuation firms, as applicable, against the actual prices at which the Company purchases and sells its investments. Based on the results of the benchmark analysis and the experience of the Company’s management in purchasing and selling these investments, FS/EIG Advisor believes that these prices are reliable indicators of fair value. FS/EIG Advisor reviewed the valuation determinations made with respect to these investments in a manner consistent with FS/EIG Advisor’s valuation policy. The following is a reconciliation for the years ended December 31, 2023 and 2022 of investments for which significant unobservable inputs (Level 3) were used in determining fair value: For the Year Ended December 31, 2023 Senior Secured Senior Secured Senior Unsecured Debt Preferred Equity Sustainable Infrastructure Investments, LLC Equity/ Total Fair value at beginning of period $ 443,245 $ 143,270 $ 10,074 $ 54,374 $ 400,414 $ 51,098 $ 491,730 $ 1,594,205 Accretion of discount (amortization of premium) 2,227 757 42 107 1,230 — — 4,363 Net realized gain (loss) (8,935) (52) 6 232 (11,847) — (27,458) (48,054) Net change in unrealized appreciation (depreciation) (61,574) (756) (87) (95) 32,308 (307) (133,481) (163,992) Purchases 95,512 — — — — — 1,746 97,258 Paid-in-kind interest 9,858 — — 4,341 — — — 14,199 Sales and repayments (243,026) (88,795) (161) (58,959) (162,115) (11,364) (94,079) (658,499) Transfers into Level 3 — — — — — — — — Transfers out of Level 3 — — — — — — — — Fair value at end of period $ 237,307 $ 54,424 $ 9,874 $ — $ 259,990 $ 39,427 $ 238,458 $ 839,480 The amount of total gains or losses for the period included in changes in net assets attributable to the change in unrealized gains or losses relating to investments still held at the reporting date $ (62,195) $ (440) $ (87) $ — $ 26,665 $ (307) $ (158,534) $ (194,898) For the Year Ended December 31, 2022 Senior Secured Senior Secured Senior Unsecured Debt Preferred Equity Sustainable Infrastructure Investments, LLC Equity/ Total Fair value at beginning of period $ 414,075 $ 84,083 $ 10,371 $ 104,659 $ 497,288 $ 50,770 $ 460,236 $ 1,621,482 Accretion of discount (amortization of premium) 1,781 275 48 151 4,194 — — 6,449 Net realized gain (loss) (12,186) 12 — (27,542) 7,203 — 71,214 38,701 Net change in unrealized appreciation (depreciation) 25,893 (644) (345) 34,305 (6,345) 328 61,335 114,527 Purchases 112,154 110,150 — 19,800 — — 16,052 258,156 Paid-in-kind interest 11,284 537 — 7,916 188 — — 19,925 Sales and repayments (168,461) (51,143) — (84,915) (102,114) — (117,107) (523,740) Transfers into Level 3 (1) 58,705 — — — — — — 58,705 Transfers out of Level 3 — — — — — — — — Fair value at end of period $ 443,245 $ 143,270 $ 10,074 $ 54,374 $ 400,414 $ 51,098 $ 491,730 $ 1,594,205 The amount of total gains or losses for the period included in changes in net assets attributable to the change in unrealized gains or losses relating to investments still held at the reporting date $ 15,525 $ (421) $ (345) $ (382) $ (3,691) $ 328 $ 74,950 $ 85,964 ________________________ (1) Changes in inputs or methodologies used for valuing investments may result in transfers into or out of levels within the fair value hierarchy.

(2) The per share data was derived by using the weighted average shares outstanding during the applicable year. (3) The per share data for distributions reflects the actual amount of distributions paid per share during the applicable year. (4) The issuance of common shares on a per share basis reflects the incremental net asset value changes as a result of the issuance of common shares pursuant to the Company’s distribution reinvestment plan. The issuance of common shares at a price that is greater than the net asset value per share results in an increase in net asset value per share. (5) The total return for each year presented was calculated based on the change in net asset value during the applicable year, including the impact of distributions reinvested in accordance with the Company’s distribution reinvestment plan. Following the termination of the Company’s distribution reinvestment plan effective September 15, 2023, the total return for each year presented subsequent to the effective date was calculated based on the change in net asset value during the applicable year, assuming the reinvestment of all distributions at the Company’s net asset value per share as of the end of the applicable period. The total return (without assuming reinvestment of distributions) for each year presented was calculated by taking the net asset value per share as of the end of the applicable year, adding the cash distributions per share which were declared during the applicable year and dividing the total by the net asset value per share at the beginning of the applicable year. The total returns do not consider the effect of any sales commissions or charges that may be incurred in connection with the sale of the Company’s common shares. The total returns include the effect of the issuance of common shares at a net offering price that is greater than net asset value per share, which causes an increase in net asset value per share. The historical calculations of total returns in the table should not be considered representations of the Company’s future total returns, which may be greater or less than the returns shown in the table due to a number of factors, including the Company’s ability or inability to make investments in companies that meet its investment criteria, the interest rates payable on the debt securities the Company acquires, the level of the Company’s expenses, variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which the Company encounters competition in its markets and general economic conditions. As a result of these factors, results for any previous year should not be relied upon as being indicative of performance in future years. The total return calculations set forth above represent the total returns on the Company’s investment portfolio during the applicable year and do not represent actual returns to shareholders. (6) Weighted average net assets during the applicable years are used for this calculation. (7) If FS/EIG Advisor had not agreed to offset the amount of any structuring, upfront or certain other fees it or its members received against the management fee payable by the Company, the ratio of net investment income to average net assets would have been 4.75%, 3.87%, 2.68%, 4.78% and 7.53% for the years ended December 31, 2023, 2022, 2021, 2020 and 2019, respectively. See Note 4 for a discussion of the management fee offset with FS/EIG Advisor. (8) Asset coverage per unit is the ratio of the carrying value of the Company's total consolidated assets, less liabilities and indebtedness not represented by senior securities, to the aggregate amount of senior securities representing indebtedness. Asset coverage per unit is expressed in terms of dollar amounts per $1,000 of indebtedness. All prior period ratios have been updated to conform with this current presentation. |

Subsequent Events [Abstract] | |
Subsequent Events | Subsequent Events BNP Paribas Total Return Swap On February 15, 2024, FSSL Finance BNPP TRS LLC, or FSSL Finance BNPP TRS, a wholly-owned financing subsidiary of the Company, entered into a loan TRS with BNP Paribas, or BNPP. The TRS with BNPP enables the Company, through its ownership of FSSL Finance BNPP TRS, to obtain the economic benefit of owning the broadly syndicated loans subject to the TRS, without actually owning them, in return for an interest-type payment to BNPP. As such, the TRS is analogous to the Company borrowing funds to acquire loans and incurring interest expense to a lender. The terms of the TRS with BNPP include, among other things, (a) payment by BNPP to FSSL Finance BNPP TRS of all interest and fees (less applicable withholding taxes) on the underlying loans, (b) payment by FSSL Finance BNPP TRS to BNPP of (i) a financing fee on the outstanding notional amount of the TRS at a rate equal to USD-SOFR Compounded Index plus 1.65% per annum, and (ii) a utilization fee of 0.85% per annum on the difference between any lesser usage amount and a $100,000 minimum usage threshold, (c) upon the termination or repayment of any loan subject to the TRS, FSSL Finance BNPP TRS either will receive from BNPP the appreciation in the value of such loan or will pay to BNPP any depreciation in the value of such loan and (d) guarantee by the Company of all obligations of FSSL Finance BNPP TRS. |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of Presentation: The accompanying audited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The Company is considered an investment company under GAAP and follows the accounting and reporting guidance applicable to investment companies under Accounting Standards Codification Topic 946, Financial Services—Investment Companies . The Company has evaluated the impact of subsequent events through the date the consolidated financial statements were issued and filed with the Securities and Exchange Commission, or the SEC. |
Use of Estimates | Use of Estimates: The preparation of the audited consolidated financial statements in conformity with GAAP requires 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. Many of the amounts have been rounded, and all amounts are in thousands, except share and per share amounts. |
Cash and Cash Equivalents | Cash and Cash Equivalents: The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company may invest its cash in a money market fund, which is stated at fair value. The Company's cash and cash equivalents are maintained with high credit quality financial institutions, which are members of the Federal Deposit Insurance Corporation. |
Valuation of Portfolio Investments | Valuation of Portfolio Investments: The Company’s board of trustees is responsible for overseeing the valuation of the Company’s portfolio investments at fair value as determined in good faith pursuant to FS/EIG Advisor’s valuation policy. As permitted by Rule 2a-5 of the 1940 Act, the Company’s board of trustees has designated FS/EIG Advisor as the Company’s valuation designee, with day-to-day responsibility for implementing the portfolio valuation process set forth in FS/EIG Advisor’s valuation policy. Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosure , or ASC Topic 820, issued by the FASB clarifies the definition of fair value and requires companies to expand their disclosure about the use of fair value to measure assets and liabilities in interim and annual periods subsequent to initial recognition. ASC Topic 820 defines fair value as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical securities; Level 2, which includes inputs such as quoted prices for similar securities in active markets and quoted prices for identical securities where there is little or no activity in the market; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. FS/EIG Advisor determines the fair value of the Company’s investment portfolio each quarter. Securities that are publicly-traded with readily available market prices will be valued at the reported closing price on the valuation date. Securities that are not publicly-traded with readily available market prices will be valued at fair value as determined in good faith by FS/EIG Advisor. In connection with that determination, FS/EIG Advisor will prepare portfolio company valuations which are based on relevant inputs, including, but not limited to, indicative dealer quotes, values of like securities, recent portfolio company financial statements and forecasts, and valuations prepared by independent third-party pricing and valuation services. With respect to investments for which market quotations are not readily available, a multi-step valuation process is undertaken each quarter, as described below: • the quarterly fair valuation process begins with FS/EIG Advisor facilitating the delivery of updated quarterly financial and other information relating to each investment to an independent third-party pricing or valuation service; • the independent third-party pricing or valuation service then reviews and analyzes the information, along with relevant market and economic data, and determines proposed valuations for each portfolio company or investment according to the valuation methodologies in FS/EIG Advisor’s valuation policy and communicates the information to FS/EIG Advisor in the form of a valuation range for Level 2 and Level 3 assets; • FS/EIG Advisor then reviews the preliminary valuation information for each portfolio company or investment and provides feedback about the accuracy, completeness and timeliness of the valuation-related inputs considered by the independent third-party pricing or valuation service and any suggested revisions thereto prior to the independent third-party pricing or valuation service finalizing its valuation range; • FS/EIG Advisor then provides the valuation committee with its valuation determinations and valuation-related information for each portfolio company or investment, along with any applicable supporting materials; and other information that is relevant to the fair valuation process; • the valuation committee meets with FS/EIG Advisor to receive the relevant quarterly reporting from FS/EIG Advisor and to discuss any questions from the valuation committee in connection with the valuation committee’s role in overseeing the fair valuation process; and • following the completion of its fair value oversight activities, the valuation committee (with the assistance of FS/EIG Advisor) provides the Company's board of trustees with a report regarding the quarterly valuation process. Determination of fair value involves subjective judgments and estimates. Accordingly, the notes to the Company's consolidated financial statements refer to the uncertainty with respect to the possible effect of such valuations and any change in such valuations on the Company's consolidated financial statements. In making its determination of fair value, FS/EIG Advisor may use any independent third-party pricing or valuation services for which it has performed the appropriate level of due diligence. However, FS/EIG Advisor is not required to determine fair value in accordance with the valuation provided by any single source, and may use any relevant data, including information sourced by FS/EIG Advisor or provided by any independent third-party pricing or valuation service that FS/EIG Advisor deems to be reliable in determining fair value under the circumstances. Below is a description of factors that FS/EIG Advisor and any independent third-party valuation services may consider when determining the fair value of the Company's investments. The valuation methods utilized for each portfolio company may vary depending on industry and company-specific considerations. Typically, the first step is to make an assessment as to the enterprise value of the portfolio company’s business in order to establish whether the portfolio company’s enterprise value is greater than the amount of its debt as of the valuation date. This analysis helps to determine a risk profile for the applicable portfolio company and its related investments, and the appropriate valuation methodology to utilize as part of the security valuation analysis. The enterprise valuation may be determined using a market or income approach. Valuation of fixed income investments, such as loans and debt securities, depends upon a number of factors, including prevailing interest rates for like securities, expected volatility in future interest rates, call features, put features and other relevant terms of the debt. For investments without readily available market prices, FS/EIG Advisor may incorporate these factors into discounted cash flow models to arrive at fair value. Various methods may be used to determine the appropriate discount rate in a discounted cash flow model. Other factors that may be considered include the borrower’s ability to adequately service its debt, the fair market value of the borrower in relation to the face amount of its outstanding debt and the quality of collateral securing the debt investments. For convertible debt securities, fair value generally approximates the fair value of the debt plus the fair value of an option to purchase the underlying security (i.e., the security into which the debt may convert) at the conversion price. To value such an option, a standard option pricing model may be used. The Company's equity interests in portfolio companies for which there is no liquid public market are valued at fair value. Generally, the value of the Company's equity interests in public companies for which market quotations are readily available is based upon the most recent closing public market price. When the Company receives warrants or other equity securities at nominal or no additional cost in connection with an investment in a debt security, the cost basis in the investment will be allocated between the debt securities and any such warrants or other equity securities received at the time of origination. FS/EIG Advisor subsequently values these warrants or other equity securities received at their fair value. Swap contracts typically are valued at their daily prices obtained from an independent third party. The aggregate settlement values and notional amounts of the swap contracts are not recorded in the consolidated financial statements. Fluctuations in the value of the swap contracts are recorded in the consolidated balance sheets as gross assets and gross liabilities and in the statements of operations as unrealized appreciation (depreciation) until closed, when they are recorded as net realized gain (loss). |
Revenue Recognition | Revenue Recognition: Security transactions are accounted for on the trade date. The Company records interest income on an accrual basis to the extent that it expects to collect such amounts. The Company records dividend income on the ex-dividend date. Distributions received from limited liability company, or LLC, and limited partnership, or LP, investments are evaluated to determine if the distribution should be recorded as dividend income or a return of capital. The Company does not accrue as a receivable interest or dividends on loans and securities if it has reason to doubt its ability to collect such income. The Company's policy is to place investments on non-accrual status when there is reasonable doubt that interest income will be collected. The Company considers many factors relevant to an investment when placing it on or removing it from non-accrual status including, but not limited to, the delinquency status of the investment, economic and business conditions, the overall financial condition of the underlying investment, the value of the underlying collateral, bankruptcy status, if any, and any other facts or circumstances relevant to the investment. If there is reasonable doubt that the Company will receive any previously accrued interest, then the accrued interest will be written-off. Payments received on non-accrual investments may be recognized as income or applied to principal depending upon the collectability of the remaining principal and interest. Non-accrual investments may be restored to accrual status when principal and interest become current and are likely to remain current based on the Company's judgment. |
Net Realized Gains or Losses, Net Change in Unrealized Appreciation or Depreciation and Net Change in Unrealized Gains or Losses on Foreign Currency | Net Realized Gains or Losses, Net Change in Unrealized Appreciation or Depreciation and Net Change in Unrealized Gains or Losses on Foreign Currency: Gains or losses on the sale of investments are calculated by using the specific identification method. The Company measures realized gains or losses by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment, without regard to unrealized appreciation or depreciation previously recognized, but considering unamortized fees. Net change in unrealized appreciation or depreciation reflects the change in portfolio investment values during the reporting period, including any reversal of previously recorded unrealized gains or losses when gains or losses are realized and the respective unrealized gain or loss on foreign currency for any foreign denominated investments it may hold. Net change in unrealized gains or losses on foreign currency reflects the change in the value of foreign currency held, receivables or accruals during the reporting period due to the impact of foreign currency fluctuations. |
Capital Gains Incentive Fee and Subordinated Income Incentive Fee | Capital Gains Incentive Fee: Subordinated Income Incentive Fee: Pursuant to the terms of the FS/EIG investment advisory agreement, FS/EIG Advisor may also be entitled to receive a subordinated incentive fee on income. The subordinated incentive fee on income under the FS/EIG investment advisory agreement is calculated and payable quarterly in arrears and equals 20.0% of the Company’s “pre-incentive fee net investment income” for the immediately preceding quarter subject to a hurdle rate, expressed as a rate of return on adjusted capital, equal to 1.625% per quarter, or an annualized hurdle rate of 6.5%. As a result, FS/EIG Advisor will not earn this incentive fee for any quarter until the Company’s pre-incentive fee net investment income for such quarter exceeds the hurdle rate of 1.625%. For purposes of this fee, ‘‘adjusted capital’’ means cumulative gross proceeds generated from sales of the Company’s common shares (including proceeds from its distribution reinvestment plan) reduced for distributions from non-liquidating dispositions of the Company’s investments paid to shareholders and amounts paid for share repurchases pursuant to the Company’s share repurchase program. Once the Company’s pre-incentive fee net investment income in any quarter exceeds the hurdle rate, FS/EIG Advisor will be entitled to a “catch-up” fee equal to the amount of the Company’s pre-incentive fee net investment income in excess of the hurdle rate, until the Company’s pre-incentive fee net investment income for such quarter equals 2.031%, or 8.125% annually, of adjusted capital. This “catch-up” feature will allow FS/EIG Advisor to recoup the fees foregone as a result of the existence of the hurdle rate. Thereafter, FS/EIG Advisor will be entitled to receive 20.0% of the Company’s pre-incentive fee net investment income. |
Fixed Price Swaps and Total Return Swaps | Fixed Price Swaps Total Return Swaps: The Company may enter into total return swaps to obtain exposure to a security or market without owning such security or investing directly in such market or to exchange the risk/return of one market with another market. Total return swaps are agreements in which there is an exchange of cash flows whereby one party agrees to make periodic payments based on the total return (distributions plus capital gains/losses) of an underlying instrument in exchange for fixed or floating rate interest payments. If the total return of the instrument or index underlying the transaction exceeds or falls short of the offsetting fixed or floating interest rate obligation, the Company receives payment from or makes a payment to the counterparty. |

Uncertainty in Income Taxes | Uncertainty in Income Taxes: The Company evaluates its tax positions to determine if the tax positions taken meet the minimum recognition threshold in connection with accounting for uncertainties in income tax positions taken or expected to be taken for the purposes of measuring and recognizing tax benefits or liabilities in the consolidated financial statements.

(2) The per share data was derived by using the weighted average shares outstanding during the applicable year. (3) The per share data for distributions reflects the actual amount of distributions paid per share during the applicable year. (4) The issuance of common shares on a per share basis reflects the incremental net asset value changes as a result of the issuance of common shares pursuant to the Company’s distribution reinvestment plan. The issuance of common shares at a price that is greater than the net asset value per share results in an increase in net asset value per share. (5) The total return for each year presented was calculated based on the change in net asset value during the applicable year, including the impact of distributions reinvested in accordance with the Company’s distribution reinvestment plan. Following the termination of the Company’s distribution reinvestment plan effective September 15, 2023, the total return for each year presented subsequent to the effective date was calculated based on the change in net asset value during the applicable year, assuming the reinvestment of all distributions at the Company’s net asset value per share as of the end of the applicable period. The total return (without assuming reinvestment of distributions) for each year presented was calculated by taking the net asset value per share as of the end of the applicable year, adding the cash distributions per share which were declared during the applicable year and dividing the total by the net asset value per share at the beginning of the applicable year. The total returns do not consider the effect of any sales commissions or charges that may be incurred in connection with the sale of the Company’s common shares. The total returns include the effect of the issuance of common shares at a net offering price that is greater than net asset value per share, which causes an increase in net asset value per share. The historical calculations of total returns in the table should not be considered representations of the Company’s future total returns, which may be greater or less than the returns shown in the table due to a number of factors, including the Company’s ability or inability to make investments in companies that meet its investment criteria, the interest rates payable on the debt securities the Company acquires, the level of the Company’s expenses, variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which the Company encounters competition in its markets and general economic conditions. As a result of these factors, results for any previous year should not be relied upon as being indicative of performance in future years. The total return calculations set forth above represent the total returns on the Company’s investment portfolio during the applicable year and do not represent actual returns to shareholders. (6) Weighted average net assets during the applicable years are used for this calculation. (7) If FS/EIG Advisor had not agreed to offset the amount of any structuring, upfront or certain other fees it or its members received against the management fee payable by the Company, the ratio of net investment income to average net assets would have been 4.75%, 3.87%, 2.68%, 4.78% and 7.53% for the years ended December 31, 2023, 2022, 2021, 2020 and 2019, respectively. See Note 4 for a discussion of the management fee offset with FS/EIG Advisor. (8) Asset coverage per unit is the ratio of the carrying value of the Company's total consolidated assets, less liabilities and indebtedness not represented by senior securities, to the aggregate amount of senior securities representing indebtedness. Asset coverage per unit is expressed in terms of dollar amounts per $1,000 of indebtedness. All prior period ratios have been updated to conform with this current presentation. |
