TNMP Files Comprehensive Rate Settlement

ALBUQUERQUE, N.M., May 29, 2026 /PRNewswire/ -- TNMP, the wholly-owned subsidiary of TXNM Energy (NYSE: TXNM) in Texas, filed a comprehensive settlement in its base rate review pending before the Public Utility Commission of Texas (PUCT). The settlement supports TNMP's continued ability to power growth in Texas with a reliable, resilient grid.

Under the terms of the settlement, TNMP recovers its filed rate base of $2.8 billion as of June 30, 2025, and continues the currently authorized return on equity of 9.65% and 45% equity ratio. Increased operations and maintenance costs that are not recovered through interim capital recovery mechanisms and changes in deferred federal income tax amortizations were partially offset by changes in depreciation rates.

Separate from the base rate request, TNMP would also implement $20.5 million in rate rider recovery associated with Hurricane Beryl restoration costs over a five-year period under the terms of the settlement.

The settlement is subject to approval by the PUCT. Under interim rates, the rates approved under a final order will relate back to May 22, 2026.

Parties joining the settlement include the Staff of the Public Utility Commission of Texas, Alliance of Texas-New Mexico Power Municipalities, Cities Served by Texas-New Mexico Power Company, Data Center Coalition, Hunt Energy Network, Joint Data Center Group, Office of Public Utility Counsel, Texas Competitive Power Advocates, Texas Industrial Energy Consumers, and Walmart. Amazon Data Systems and Texas Energy Association for Marketers do not oppose the stipulation.
