At Xcel Energy, we pride ourselves on providing reliable and affordable service to our customers. A major part of making that goal a success is a strong transmission system. We currently own and maintain more than 20,000 miles of transmission lines and more than 1,200 substations across 10 states. But just like any major infrastructure, the transmission grid needs to be upgraded and expanded to serve new and existing customers.
