CenterPoint Energy's electric transmission and distribution unit serves more than 2.1 million customers in a 5,000 square-mile area that includes Houston, the nation’s fourth largest city and a consistently growing market. As a regulated "wires" utility, we neither generate power nor sell it to end-use customers. We instead own, operate and maintain the poles, wires and substations that make the delivery of electricity from power plants to customers safe and reliable. With over 3,700 miles of transmission lines and 47,000 miles of distribution lines, we deliver electricity on behalf of 85 retail electric providers.
