FERC Clears Blackstone-TXNM Deal, Narrowing Regulatory Uncertainty for PNM Resources

FERC sign-off narrows regulatory uncertainty for PNM Resources

The Federal Energy Regulatory Commission is authorising Blackstone Infrastructure’s acquisition of TXNM Energy, a move that directly affects PNM Resources’ regulated utility, PNM. In a Feb. 20 order, FERC finds the transaction consistent with the public interest and concludes there is “no evidence that either state or federal regulation will be impaired,” that the deal will not have an adverse effect on rates, and that horizontal or vertical competition is not harmed. FERC rejects opposition arguments tied to Blackstone’s private equity ownership and data‑center holdings, and relies on existing and committed ring‑fencing protections in New Mexico and Texas to limit potential cross‑subsidization or operational interference.

The ruling follows a string of prior clearances that reduce near‑term regulatory risk for PNM Resources. The FCC already grants federal telecom‑related approval, the Hart‑Scott‑Rodino waiting period has expired, and the Public Utility Commission of Texas approved a settlement earlier this month after TXNM Energy shareholders overwhelmingly backed the merger in August 2025. Company officials say closing still hinges on Nuclear Regulatory Commission and New Mexico Public Regulation Commission approvals and customary closing conditions, and timing will depend on those outstanding regulatory schedules.

For PNM Resources and its customers, the FERC decision removes a major federal hurdle and narrows the focus of remaining reviews to state and nuclear oversight. TXNM Energy delivers power to more than 800,000 homes and businesses across Texas and New Mexico through TNMP and PNM; FERC’s emphasis on ring‑fencing is intended to preserve ratepayer protections and regulatory authority while enabling the transaction. The requirement for NRC sign‑off highlights special scrutiny for any nuclear assets and keeps reliability and safety at the centre of the next phase.

Remaining approvals and next steps

The deal still requires NRC approval for any nuclear facilities and a decision from the New Mexico Public Regulation Commission. TXNM Energy says completion remains subject to customary closing conditions and that stakeholders can monitor filings and updates on the company’s investor relations site for timing and regulatory schedules.

Policy and market implications for utilities

FERC’s rejection of opposition rooted in private equity ownership and data‑center exposure signals regulatory willingness to permit PE involvement in regulated utilities when explicit protections are in place. Regulators, utilities and customers will watch ring‑fencing implementation and state reviews closely as a precedent for future infrastructure transactions.
