If the filing person has previously filed a statement on Schedule 13G to report the acquisition that is the subject of this Schedule 13D, and is filing this schedule because of Rule 13d-1(e), 13d-1(f) or 13d-1(g), check the following box ☐.

Note: Schedules filed in paper format shall include a signed original and five copies of the schedule, including all exhibits. See Rule 13d-7 for other parties to whom copies are to be sent.

The information required on the remainder of this cover page shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended (the “Act”), or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

Explanatory Note

This Amendment No. 1 (this “Amendment”) amends and supplements the Schedule 13D filed by the Reporting Person on September 2, 2021 (the “Original Schedule 13D” and, as amended and supplemented by this Amendment, the “Schedule 13D”). Except as specifically provided herein, this Amendment does not modify any of the information previously reported on the Original Schedule 13D. Capitalized terms not otherwise defined in this Amendment shall have the same meanings ascribed thereto in the Original Schedule 13D.

This Schedule 13D relates to the Class A ordinary shares, nominal value of $0.0001 (the “Shares”), of ReNew Energy Global plc, a public limited company incorporated in England and Wales (the “Issuer”), having its registered office at c/o Vistra (UK) Ltd, 3rd Floor, 11-12 St. James’s Square, London, SW1Y 4LB United Kingdom.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

(a) and (b) JERA Power RN B.V. (“JERA Netherlands”) is the record holder of and beneficially owns 28,524,255 Class A Ordinary Shares of the Issuer, which represent approximately 11.7% of the Issuer’s outstanding Class A Ordinary Shares. This percentage is calculated based on 244,266,823 Class A Ordinary Shares (excluding treasury shares) outstanding as of March 31, 2024, which represents the most recent date for which such information was made available by the Issuer to the Reporting Persons.

JERA Co., Inc. (“JERA Japan”), as the parent company of JERA Netherlands, may be deemed to beneficially own all of the Class A Ordinary Shares in the Issuer held directly by JERA Netherlands.

In addition, by virtue of the rights and obligations under Registration Rights, Coordination and Put Agreement and the Amended Shareholders Agreement (as defined below), certain of the other parties to those agreements, their affiliates and the Reporting Persons may each be deemed to be a member of a “group” for purposes of Section 13(d) of the Exchange Act. This filing shall not be deemed an admission that the Reporting Persons and such other persons constitute a “group” for purposes of Section 13(d) of the Exchange Act, and the Reporting Persons expressly disclaim membership in any such group. Such other persons have separately made Schedule 13D filings reporting their beneficial ownership of shares of Common Stock.

(c) Except as described in this Schedule 13D, neither the Reporting Persons nor, to the Reporting Persons’ knowledge, any Covered Person have engaged in any transactions with respect to the Class A Ordinary Shares in the past 60 days.

(d) To the knowledge of the Reporting Persons, no person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any securities of the Issuer beneficially owned by the Reporting Persons as described in this Item 5.

(e) Not applicable.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER

This Amendment amends and supplements Item 6 of the Original Schedule 13D by adding the following:

Amended Shareholders Agreement

All capitalized terms used but not otherwise defined under this heading shall have the meanings ascribed to such terms in the Amended Shareholders Agreement.

On July 24, 2023, JERA Netherlands entered into an Amendment to Shareholders Agreement (“Amendment to Shareholders Agreement”, and the Shareholders Agreement, as amended by the Amendment to Shareholders Agreement, the “Amended Shareholders Agreement”) with the other Shareholders Agreement Investors. A copy of the Amendment to Shareholders Agreement is attached hereto as Exhibit 99.6.

Pursuant to the Amended Shareholders Agreement:

(i) from and after the Second Anniversary Date, the Board shall be comprised of (i) up to ten (10) Directors, if there are three (3) or fewer Investor Nominee Directors (other than the Founder Director) or (ii) up to eleven (11) Directors, if there are four (4) Investor Nominee Directors (other than the Founder Director), in each case (A) a majority of whom shall be Independent Directors, and (B) at least two (2) of the directors shall be female; and

(ii) JERA Netherlands shall be entitled from time to time to appoint one person as an observer on the Board and to remove any such person so appointed and appoint another person in that person’s place, provided that JERA Netherlands together with its Affiliates, holds at least forty percent (40%) of the Class A Shares held by JERA Netherlands as of the Closing Date (excluding, for the avoidance of doubt, any dilution resulting from any Share issuance by the Company after the Closing Date) and JERA Netherlands does not hold a Director Appointment Right pursuant to Section 2.1(c)(v) of the Amended Shareholders Agreement at the relevant time.
