TXNM

Txnm Energy, Inc.

A regulated electric utility holding company based in Albuquerque, New Mexico, TXNM Energy delivers power to homes and businesses across New Mexico and Texas through its two subsidiaries, Public Service Company of New Mexico (PNM) and Texas-New Mexico Power. Its roots go back to 1917, when the Albuquerque Gas and Electric Company was formed by merging two local utilities. The company renamed itself TXNM Energy in 2024 to reflect its footprint in both states, and its early days saw the arrival of Albuquerque's first natural gas pipeline, which finally ended the coal soot that used to blacken residents' drapes and furniture.
