Rocky Mountain Power is planning major investments in Wyoming between now and 2020 to add new wind generation, upgrade existing wind farms and build new transmission. This plan will help diversify the state’s economy, create jobs and add to the tax base.

The $3.5 billion investment includes:

  • Up to 1,100 megawatts of new wind by 2020, primarily in Wyoming
  • “Repowering” the existing company-owned Wyoming wind fleet with longer blades and newer technology to increase energy production and extend the life of the projects
  • Construction of a new 140-mile Gateway West transmission segment by 2020

The availability of federal tax credits will help cover the costs of these investments and provide a net savings to customers over the life of the projects.

We expect these projects to:

  • Create between 1,100 and 1,600 construction jobs in Wyoming
  • Add approximately $115 million in tax revenue through construction, and an additional $14 million annually in wind and property tax revenue starting on 2021

These investments mark a major expansion of the amount of clean, renewable energy serving Rocky Mountain Power customers, and will meet customer needs while costing customers less than any other alternatives. This is a win-win and represents our continued commitment to both diversify our energy resources and keep costs low.


How will this benefit Wyoming?

  • These investments mark a major expansion of the amount of clean, renewable energy serving our customers, and provide a net cost savings at the same time. This is a win-win and represents our continued commitment to both diversify our energy resources and keep costs low.
  • Coal and gas will remain important industries in Wyoming. These investments can provide the benefits of diversifying the economy without threatening existing industries and jobs.
  • These projects will deliver cost-effective energy to Wyoming and other PacifiCorp customers, and can do so while saving our customers over the life of the investment.
  • We are doing this because we believe this is a significant benefit for our customers and saves money. We wouldn’t go forward with this if we didn’t see benefit for our customers.  
  • The additional transmission segment will also help the company deliver energy more efficiently and cost effectively, including from Wyoming wind and coal plants. Relieving transmission bottlenecks will actually allow the Dave Johnston and Wyodak plants to run more than they currently do.

We have done our due diligence and believe that Wyoming citizens agree the state will benefit from additional jobs, more revenue, additional transmission infrastructure, affordable electricity service, and economic diversity. We want to be a part of Wyoming’s continued energy leadership and its “all of the above” energy economy.

Energy Vision 2020

As stated in its 2017 Integrated Resource Plan, PacifiCorp has identified plans to add new Wyoming wind resources in combination with a new 500 kV transmission line (Aeolus to Bridger/Anticline) that can achieve commercial operation by December 31, 2020. With full production tax credit (PTC) eligibility the new wind, which requires the new transmission line, yields all-in economic benefits for PacifiCorp’s customers.

This 2017R Request for Proposals (RFP) will seek up to 1,270 MW of wind resources that can achieve a commercial operation date of no later than December 31, 2020.
