TXNM Energy, Inc., through its various subsidiaries, supplies electricity and related services across the United States. Its operations are organized into two main divisions: Public Service Company of New Mexico (PNM) and Texas-New Mexico Power Company (TNMP). The PNM segment is responsible for producing, transmitting, and distributing electrical energy. This division either owns or leases essential assets, including communication systems, office and other equipment, office spaces, vehicles, and real estate. PNM generates electricity from a diverse portfolio of sources such as coal, natural gas, oil, nuclear fuel and waste, alongside renewables like solar, wind, geothermal, and battery storage. In contrast, the TNMP segment focuses on providing regulated transmission and distribution infrastructure. It also maintains a fleet of vehicles, service facilities, and office locations, which are either owned or leased throughout its service area. The company delivers power to residential, commercial, and industrial consumers, as well as other electricity end-users in New Mexico and Texas. Originally established in 1882 and headquartered in Albuquerque, New Mexico, the company adopted its current name, TXNM Energy, Inc., in August 2024, having previously operated as PNM Resources, Inc.
