1946-1947
In 1946, the Albuquerque Gas and Electric Company changed its corporate name to the Public Service Company of New Mexico (PNM) and acquired the properties of utilities in other New Mexico cities, including New Mexico Power Company, Deming Ice and Electric Company, and Las Vegas Light and Power Company.
However, post war growth and the inability to build anything new during the war left the company in a difficult situation trying to meet the supply and demand needs of electricity for its customers.
1948
PNM goes public and operates as an independent utility.
1949
PNM sells its retail gas operation to the Southern Union Company and concentrates on electrical operations.
