TNMP Electric Bill

For the majority of Texas, the electric bill will come from the retail energy provider. The delivery charge in Texas is known as the transmission and distribution utility (TDU) charge. This represents the regulated section of the electric bill. A customer living in the TNMP service area will not be able to change to another utility company for the TDU charge. Texas-New Mexico Power’s TDU charge is regulated by the Public Utility Commission of Texas.

The supply charge represents the deregulated section of the electric bill. Customers can shop around for an energy supplier to lower the supply rate on the electric bill. When you sign up with a new energy provider, Texas-New Mexico Power will be notified and will be responsible for switching the customer from the old energy provider to the new one. The process will be automatic and you will not have to worry about contacting the old energy provider to cancel.
