Gateway West will help energy companies across the western United States integrate and balance a growing amount of wind and solar energy. It also will strengthen energy markets and help stabilize customer prices by giving companies more opportunities to buy and sell energy to meet their customers’ needs.

Idaho Power and PacifiCorp are working together to build this 1,000-mile, high-voltage transmission line across Wyoming and southern Idaho. The project will help both companies meet rising customer demand and improve reliability.

You can find more information, including project schedules, on PacifiCorp’s project webpage (This link will send you to a third-party website. Idaho Power is not responsible for the content or accuracy of information on third-party websites.).
