Rocky Mountain Power’s $2b transmission plan moves forward

CHEYENNE, Wyo. – Rocky Mountain Power filed for regulatory approval with the Wyoming Public Service Commission to begin construction on the next phase of its multi-billion dollar infrastructure investment plan, of which approximately $5 billion is in Wyoming. If approved, the comprehensive energy plan will provide substantial customer benefits in Wyoming and will support local communities with safe, reliable, affordable electric service along with significant economic development opportunities.

This phase includes $2 billion in new transmission facilities, of which approximately $915 million is in Wyoming, to strengthen the overall reliability of the existing transmission system and allow for additional interconnection of new Wyoming generation resources. The transmission projects are expected to provide more than 500 construction jobs and approximately $17 million in tax revenue for Wyoming. In addition, the estimated $2 billion in new Wyoming generation resources that the transmission projects facilitate will add approximately $96 million in tax revenue through construction and more than $10 million in annual property tax revenue for Wyoming. Together, these projects ensure Wyoming electricity remains affordable and reliable for customers and competitive for attracting new business.

“Wyoming has long played a critical role in supplying our nation’s energy needs and we appreciate the opportunity to work with our partners to ensure Wyoming remains one of the nation’s top energy producers,” said Sharon Fain, vice president for Rocky Mountain Power in Wyoming. “Together with the people, businesses and communities of Wyoming, we’re committed to developing the energy infrastructure needed for the state to remain competitive and attractive to new businesses and help existing businesses grow.”

As part of the filing, the company is seeking approval to allow construction to begin on new projects, which include:

• Construction of Gateway South, a new 500 kV 414-mile transmission segment, 142 miles of which will be in Wyoming
• Additional Gateway West construction with approximately 120 miles of new and rebuilt transmission lines

This new phase builds on existing wind energy investments made through Rocky Mountain Power’s Energy Vision 2020, a $3.1 billion total investment, of which over $2 billion is invested in Wyoming, that significantly expands the capacity to provide more wind power to customers, creates a cleaner energy future, and keeps energy bills affordable, with reliable service and rates 20 percent below the national average.

If approved by the Wyoming Public Service Commission, the company plans to begin construction by August 1, 2021, and complete the projects by December 31, 2023.
