Rocky Mountain Power Advances $3.5 Billion Wind and Transmission Investment

June 29, 2017


SALT LAKE CITY — Rocky Mountain Power is asking regulators in three states to approve an initial plan to significantly expand the amount of wind power serving customers by 2020.

Regulatory filings in Wyoming, Utah and Idaho, which will be made by June 30, seek to advance the company’s Energy Vision 2020 initiative. The plan would:

  • Upgrade or “repower” the company’s existing wind fleet with longer blades and newer technology
  • Add approximately 1,100 megawatts of new wind
  • Build a new 140-mile Gateway West transmission segment

Most of the new investments will be in Wyoming.

“We are very excited to begin the stakeholder review process for these projects that will significantly increase the renewable energy that serves all our customers,” said Cindy A. Crane, Rocky Mountain Power President and CEO. “These investments will provide significant long-term benefits to our customers and bring substantial economic benefits to rural communities where the facilities will be located.” 

The company first announced the wind and transmission investments in April as part of its broader long-term energy plan. Additional filings and regulatory approvals will be needed for the projects to be built and serving customers by 2020 as planned.

The Energy Vision 2020 projects were chosen by the company as the most cost-effective option to meet customers’ energy needs over the next 20 years. By moving to complete the projects by 2020, the company will be able to use federal production tax credits to provide a net cost savings to customers over the life of the projects.

The projects are also expected to:

  • Create between 1,100 and 1,600 construction jobs in Wyoming
  • Add approximately $120 million in tax revenue from construction
  • Bring significant post-construction annual tax revenues starting at approximately $11 million in 2021 and growing to $14 million annually by 2024
