Community Public Service serviced most of the communities now served by TNMP, plus some additional communities in Texas and communities in New Mexico. It operated as power producer, distribution company and provider of customer service and billing.

Interestingly, TNMP briefly ventured into other businesses. Their list of industries includes natural gas, ice, telephone, sewer, creameries, and bottling.
