About TNMP

The Texas-New Mexico Power (TNMP) company dates from the formation of the Texas-Louisiana Power Co. in 1925. But while it served thousands of customers in small towns through out the southwest as well as Louisiana and Kentucky, the hard times of the Great Depression forced the company to reorganize in 1934. Emerging as the Community Public Service Co. on January 1, 1935, it operated businesses in natural gas, ice, telephone, sewer, creameries and bottling. From the late 1940s, the company sold off its non-electric utility businesses, finally transforming all of its operations to electric utility business by the 1970s.

In 1981, Community Public Service changed its name to Texas-New Mexico Power (TNMP), reflecting its operations in both Texas and New Mexico. When Texas deregulated its electricity market in 2002, TNMP became a transmission and distribution service provider by shedding it generation operations in Texas. In 2006, the company transferred its New Mexico utility operations to its sister company in New Mexico.

TNMP is now a Texas-only TDSP/TDU based in Lewisville. It supports numerous charitable organizations through its annual Power Grants that go to schools, animal shelters, food banks, education programs, non-profits, and more.
