Ladies and Gentlemen:

We have acted as California counsel to Sempra Energy, a corporation organized under the laws of California (the “Company”), in connection with the preparation and filing by the Company with the Securities and Exchange Commission (the “Commission”) of a registration statement on Form S-4 (File No. 333-252030) filed on January 12, 2021 (as amended, the “Registration Statement”) relating to the registration under the Securities Act of 1933, as amended (the “Securities Act”), of 13,993,739 shares of the Company’s common stock, no par value (the “Common Stock”) to be offered in exchange for each issued and outstanding ordinary, nominative share, of a single-series, no par value (the “Ordinary Shares”) of Infraestructura Energética Nova, S.A.B. de C.V. (“IEnova”), a Mexican public stock corporation, other than such Ordinary Shares owned directly or indirectly by the Company, at an exchange ratio equal to 0.0313 shares of Common Stock for each Ordinary Share.

This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended (the “Act”).

In our capacity as such counsel, we are familiar with the actions taken and proposed to be taken by the Company in connection with the registration and issuance of the Common Stock, each as described in the Registration Statement. For purposes of this opinion letter, and except to the extent set forth in the opinions below, we have assumed that all such actions have been timely completed or will be timely completed in the manner presently proposed in the Registration Statement.

In connection with our opinions expressed below, we have examined originals or copies certified or otherwise identified to our satisfaction of the following documents and such other documents, corporate records, certificates and other statements of government officials and corporate officers of the Company as we deemed necessary for the purposes of the opinions set forth in this opinion letter:

(a)

a copy of the By-Laws of the Company as in effect on the date hereof, certified by the Secretary of the Company;

(d)

a copy of Resolutions of the Board of Directors of the Company adopted on November 3, 2020 and January 9, 2021 and of the Transaction, Pricing and Capital Recycling Committee of the Board of Directors of the Company adopted on April 10, 2021, certified by the Secretary of the Company; and

We have relied, to the extent we deem such reliance proper, upon such certificates or comparable documents of officers and representatives of the Company and of public officials and upon statements and information furnished by officers and representatives of the Company with respect to the accuracy of material factual matters contained therein which were not independently established by us.

Based upon the foregoing assumptions and the assumptions set forth below, and subject to the qualifications and limitations stated herein, having considered such questions of law as we have deemed necessary as a basis for the opinions expressed below, we are of the opinion that the shares of Common Stock to be issued by the Company pursuant to and in the manner contemplated in the Registration Statement will be, upon issuance, duly authorized and, when the shares of Common Stock have been delivered by the Company upon the terms and conditions set forth in the Registration Statement, the shares of Common Stock will be validly issued, fully paid and nonassessable.

The opinion expressed above is limited to questions arising under the Corporations Code of the State of California. We do not express any opinion as to the laws of any other jurisdiction.

We assume no responsibility to update this opinion letter for, or to advise you of, any such facts or circumstances of which we become aware, regardless of whether or not they affect the opinions expressed in this opinion letter.

We hereby consent to the filing of this opinion letter as Exhibit 5.1 to the Registration Statement and to the reference to our firm as counsel for the Company that has passed on the validity of the Common Stock appearing under the caption “Legal Information—Legal Matters” in the Registration Statement.
