Schedule 13D

Schedule 13D

The class of equity security to which this statement on Schedule 13D relates are
the Common Shares (the Common Shares) of Cheniere Energy Partners LP Holdings, LLC (the Issuer), a Delaware limited liability company. The address of the principal executive offices of the Issuer is 700 Milan Street, Suite
1900, Houston, Texas 77002.

Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.

(a)    The persons filing this Schedule 13D (collectively,
the Reporting Persons) are:

1.    Zimmer Partners, LP (the Investment Manager)

2.    Zimmer Partners GP, LLC (the Zimmer GP)

3.    Stuart J. Zimmer

(b) The business
address or address of its principal office, as applicable, of the Reporting Persons is:

9 West 57th Street, 33rd Floor

New York, NY 10019

(c) Each of the Reporting Persons is engaged
in the business of investing. The Investment Managers principal business is serving as investment manager to certain private investment funds (collectively, the Zimmer Accounts). Zimmer GPs principal business is serving as
the general partner of the Investment Manager. The principal business of Stuart J. Zimmer is serving as the sole member of Zimmer GP.

(d) and
(e) During the past five years, none of the Reporting Persons nor any of the Zimmer Accounts has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding
of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or
state securities laws or finding any violation with respect to such laws.

(f) The citizenship with respect to a natural person or state of organization
with respect to an entity, as applicable, of the Reporting Persons is as follows:

The aggregate purchase price of the Common Shares
directly held by the Zimmer Accounts reported herein was $273,868,726. The Common Shares directly held by the Zimmer Accounts were purchased with the working capital of the Zimmer Accounts (which may, at any given time, include margin loans made by
brokerage firms in the ordinary course of business). Unless otherwise indicated in Item 5(c) to this Schedule 13D, all Common Shares reported herein were purchased in open market transactions through a broker. The Common Shares directly held by the
Zimmer Accounts are currently held in margin accounts.

The Reporting Persons acquired Common Shares of the Issuer on behalf of the
Zimmer Accounts for investment purposes in the belief that the Common Shares were undervalued and represented an attractive investment opportunity. The Reporting Persons are supportive of the Issuers management and its strategy.

On September 30, 2016, the Issuer announced that the Issuers Board of Directors (the Board) received a proposal from Cheniere Energy,
Inc. (Cheniere) pursuant to which Cheniere would acquire the publicly held shares of the Issuer not already owned by Cheniere in a stock-for-stock exchange
at a proposed ratio of 0.5049 Cheniere shares for each issued and outstanding publicly-held Common Share of the Issuer as part of a transaction that would be structured as a merger of the Issuer with a wholly-owned subsidiary of Cheniere (the
Cheniere Proposal). On October 11, 2016, the Reporting Persons sent a letter to the Board expressing their dissatisfaction with the terms of the Cheniere Proposal. Subsequent to sending the letter, representatives of the Reporting
Persons discussed their financial analysis of the Cheniere Proposal with members of the Issuers independent directors and their financial adviser and explained why the Reporting Persons believe that the Cheniere Proposal undervalued the
Issuer.

On April 10, 2017, representatives of the Reporting Persons met with the Chief Executive Officer of Cheniere and discussed the Reporting
Persons investment in the Issuer in broad terms and the potential for negotiating a possible transaction with Cheniere involving the Common Shares beneficially owned by the Reporting Persons. On May 1, 2017, the Reporting Persons sent a
proposal to the management of Cheniere pursuant to which the Reporting Persons would exchange the Common Shares beneficially owned by them for consideration that valued the Common Shares at a premium to the all time high price for the Common Shares.
Cheniere subsequently rejected the proposal.

Going forward, although the Reporting Persons intend to continue acquiring Common Shares of the Issuer, the
Reporting Persons will consider various alternatives for disposing of the Common Shares they beneficially own, including as a result of additional negotiations with Cheniere for an exchange of the Common Shares for securities of Cheniere or other
consideration, including cash. The Reporting Persons would also consider participating with other holders of Common Shares to negotiate a transaction directly with the
Issuer.

The Reporting Persons have had discussions with
members of the Issuers management and other holders of Common Shares in connection with the Reporting Persons investment in the Issuer and may from time to time have further discussions with officers of the Issuer, members of the Board
or discussions with other holders of Common Shares or third parties regarding potential transactions in Common Shares, potential corporate transactions involving the Issuer and other matters related to the Issuer, including one or more items in
subsections (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect
thereto.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis and may from time to time and at any time in the
future depending on various factors, including, without limitation, the outcome of any discussions referenced above, the Issuers financial position and strategic direction, actions taken by the Board, price levels of the Issuers
securities, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, take such actions with respect to the investment in the Issuer as they deem appropriate.
These actions may include: (i) acquiring additional Common Shares and/or other equity, debt, notes, other securities, or derivative or other instruments that are based upon or relate to the value of securities of the Issuer (collectively,
Securities) in the open market or otherwise; (ii) disposing of any or all of their Securities in the open market or otherwise; (iii) continuing to hold the Common Shares, (iv) engaging in any hedging or similar
transactions with respect to the Securities; or (v) proposing or considering one or more of the actions described in subsections (a) through (j) of Item 4 of Schedule 13D.

Except as set forth herein, the Reporting Persons do not have present plans or proposals at this time that relate to or would result in any of the
transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

(a) and (b) Items 7 through 11 and 13 of each of the cover
pages of this Schedule 13D are incorporated herein by reference. Such information is based on 231,700,000 Common Shares outstanding as of April 28, 2017, as reported in the Issuers Form 10-Q filed
with the Securities and Exchange Commission on May 4, 2017.

The Zimmer Accounts have delegated to the Investment Manager sole voting and investment power over the securities
held by the Zimmer Accounts pursuant to their respective Investment Management Agreements with the Investment Manager. As a result, each of the Investment Manager, Zimmer GP, as the general partner of the Investment Manager, and Stuart J. Zimmer, as
the sole member of Zimmer GP, may be deemed to exercise voting and investment power over the Common Shares directly held by the Zimmer Accounts. The Zimmer Accounts specifically disclaim beneficial ownership of the securities of the Issuer directly
held by them by virtue of their inability to vote or dispose of such securities as a result of their respective Investment Management Agreements with the Investment Manager.

Set forth below is the aggregate number of Common Shares directly held, as of the date hereof, by each of the following Zimmer Accounts.

(c) Transactions by the Reporting Persons (on behalf of the Zimmer Accounts) effected during the past 60 days are set forth in
Schedule A below and such information is incorporated herein by reference.

(d) The disclosure regarding the relationship between the
Reporting Persons in Item 2(c) of this Schedule 13D is incorporated by reference herein. All securities reported in this Schedule 13D are directly held by the Zimmer Accounts, all of which are investment management clients of the Investment
Manager. None of the Zimmer Accounts individually directly holds more than 5% of the Issuers outstanding Common Shares. The limited partners of (or investors in) each of the Zimmer Accounts have the right to participate in the receipt of
dividends from, or proceeds from the sale of, the Common Shares held for the accounts of their respective Zimmer Accounts in accordance with their respective limited partnership interests (or investment percentages) in their respective Zimmer
Accounts.

(e) Not applicable.

None.
