Energy Gateway

Bringing New Transmission to the West

Attention is focusing on our nation's electrical transmission system, especially in the West where there has been very little investment in new transmission infrastructure for nearly 20 years. During that time, population, communities and electricity demand in the region have all grown significantly. The transmission system is reaching capacity in many places and is bottlenecked in others.

PacifiCorp is leading the way to change that. In May 2007, PacifiCorp launched the Energy Gateway Transmission Expansion - an ambitious, multi-year $6 billion-plus investment plan that will add approximately 2,000 miles of new transmission line across the West. Energy Gateway, and projects planned by other entities, will alleviate constraints and address current and future growth of many kinds.

Today, construction is underway on one Energy Gateway segment and outreach, siting and permitting processes continue for several others. Major segments are scheduled to be in service by 2014.

Among its benefits, Energy Gateway will provide access to conventional energy sources and connect areas where renewable energy development possibilities are strong, as shown in these regional maps of wind (PDF), solar, biomass and geothermal (PDF) potential. Learn more about how Energy Gateway supports renewable resource development (PDF).

Along with population and energy demand growth, investment in our transmission system also is driven by our Integrated Resource Plan. This plan identifies a need for more transmission lines to deliver electricity from new generating resources – either from new generating plants, or to provide a path for additional energy purchases from other entities in the region.

The Energy Gateway map shows the individual segment additions to the transmission system to complete the expansion at its potential full build. Depending on regional, third-party and local participation, the final lines may vary somewhat. PacifiCorp is taking every reasonable step to accommodate broad regional transmission needs but will, at minimum, build Energy Gateway to first meet our commitment to provide our customers with safe, reliable and reasonably priced electrical service.
