About Texas-New Mexico Power

Texas-New Mexico Power, also known as TNMP, began in 1934 as Community Public Service Co. In 1935, it took ownership of Texas-Louisiana Power Co., so the company has been around for decades.

Understanding energy deregulation in Texas

Electricity utilities in the U.S. follow many different structures, which vary by state. Some states encourage market competition among energy suppliers, giving the consumers more choice. This is called deregulation

Five million residents in Texas have had the choice of electricity provider since the state was deregulated in 2002.

Put simply, deregulation means Texas electricity customers – or at least about 85 percent of them – have the power to choose the company that supplies the energy they use. These companies are called retail electricity providers (REPs), and they are different from utilities such as Texas-New Mexico Power. 

What’s the difference between a utility and a provider?

Texas-New Mexico Power is a utility, which means it’s the company that delivers electricity to your home. Utilities also maintain the electrical equipment in your area, so those companies respond to power outages and oversee repairs on downed power lines. 

Providers, in contrast, either generate or buy the energy and provide it to the utility for delivery. They also coordinate the process when you switch from one provider to another. These switches usually can be done without a technician visit to your home.
