Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Stonepeak-Plus Infrastructure Fund LP (the “Partnership”), is a Delaware limited partnership which was formed on April 29, 2024. The Partnership is governed by its Amended and Restated Limited Partnership Agreement dated as of May 2, 2025 (as amended, restated and/or supplemented from time to time, the “Partnership Agreement”). The Partnership was initially formed under the name “Stonepeak Access Fund LP” and has changed its name pursuant to an amendment to the certificate of limited partnership of the Partnership, as filed in Delaware on October 15, 2024, to “Stonepeak-Plus Infrastructure Fund LP”. The Partnership is a private fund exempt from registration under Section 3(c)(7) of the Investment Company Act of 1940, as amended (the “1940 Act”). Stonepeak-Plus Infrastructure Fund Advisors LLC (the “Investment Advisor”), is the investment advisor of the Partnership. The Investment Advisor is a registered investment advisor with the U.S. Securities and Exchange Commission (the “SEC”) under the Investment Advisers Act of 1940 (the “Advisers Act”) by virtue of being a relying adviser of one of its affiliates. As of March 31, 2025, the Partnership has the authority to issue unlimited Units of all classes of Units and had not commenced operations. The Partnership’s initial closing date will be the date on which the Partnership accepts its first third-party investors and begins investment operations (the “Initial Closing Date”). As of March 31, 2025, the Partnership has not accepted third-party investors. Stonepeak-Plus Infrastructure Fund (TE) LP (the “Feeder Fund”), a Delaware limited partnership, is a feeder vehicle for the Partnership. The Feeder Fund intends to invest all or substantially all of its assets in the Partnership. The Feeder was established for certain investors with particular tax characteristics, such as tax-exempt investors and certain non-U.S. investors. Stonepeak-Plus Infrastructure Fund Associates LP, (the “General Partner”), may create one or more parallel vehicles established by, or at the direction of, the General Partner or any Affiliate thereof to invest alongside the Partnership in Stonepeak-Plus Infrastructure Fund Master Aggregator LP, (the “Master Aggregator”), a Cayman Islands exempted limited partnership, or any other Intermediate Entity, (collectively, “Parallel Funds”) to accommodate legal, tax, regulatory, compliance, or certain other operational requirements which will generally co-invest (either directly or indirectly) in its investments with the Partnership on a pro rata basis. The General Partner may, in its sole discretion, cause the Partnership to hold certain investments directly or indirectly through (i) one or more corporations or (ii) one or more limited liability companies or limited partnerships or other similar entities (each, a “Lower Fund” and together with any corporation, and including Stonepeak-Plus Infrastructure Fund Aggregator I LP, the Master Aggregator and any other vehicle(s) used to aggregate the holdings of the Fund and any Parallel Funds, “Intermediate Entities”). Overall responsibility for the Partnership’s oversight rests with the General Partner, subject to certain oversight rights held by the Partnership’s Board of Directors (the “Board of Directors” or “Board”). The Partnership’s investment objective is to deliver strong total returns, with a focus on capital appreciation and generating current income through its investments. The Partnership seeks to achieve this investment objective by providing access to the talent and investment capabilities of the investment program designed to offer eligible individuals access to Stonepeak’s infrastructure platform (the “Stonepeak Platform”) to create an attractive portfolio of diversified alternative infrastructure and infrastructure-related investments primarily in, or alongside, other investment vehicles managed by the Investment Advisor or affiliated investment advisors. The Partnership entered into a services agreement with SS&C (the “Administrator”), under which the Administrator provides various accounting and administrative services to the Partnership. Administrative services may include maintenance of the Partnership’s books and records, processing of investor transactions, and calculation of the net asset value (the “NAV”). Administrative services will commence once the Partnership commences operations. As of March 31, 2025, the Partnership had not commenced operations and no Administration Fee was accrued or paid during the period ended March 31, 2025. The Partnership expects to conduct a continuous private offering (the “Private Offering”) of its units in reliance on exemptions from the registration requirements of the Securities Act of 1933 (as amended, the “Securities Act”) to investors that are both (i) accredited investors (as defined in Regulation D under the Securities Act) and (ii) qualified purchasers (as defined in the 1940 Act and rules thereunder). The Partnership is structured as a perpetual-life strategy, with monthly, fully funded subscriptions and periodic repurchase offers, which enables investors to gain exposure to private markets asset classes, such as infrastructure and real assets.
