Last Friday, PacifiCorp announced they will no longer invest in new coal or natural gas projects.  What will this mean for their coal reliant business unit in Wyoming, Rocky Mountain Power?  Will a recent bill extend the lives of the 19 active coal units PacifiCorp plans to retire?  The company will invest heavily into renewables, adding more than 3,600 megawatts of wind, more than 5,600 megawatts of solar, and 6,700 megawatts of battery storage.

TerraPower, Wyoming Governor and PacifiCorp announce efforts to advance nuclear technology in Wyoming

"CHEYENNE, Wyo. — TerraPower, Wyoming Gov. Mark Gordon and PacifiCorp today announced efforts to advance a Natrium™ reactor demonstration project at a retiring coal plant in Wyoming. The companies are evaluating several potential locations in the state. 

'Together with PacifiCorp, we’re creating the energy grid of the future where advanced nuclear technologies provide good-paying jobs and clean energy for years to come,' said Chris Levesque, president and CEO of TerraPower. 'The Natrium technology was designed to solve a challenge utilities face as they work to enhance grid reliability and stability while meeting decarbonization and emissions-reduction goals.'"

Great news Bob...

While we wait for that possible nuclear demonstration project in Wyoming - maybe by 2032? -  we can celebrate the recently completed Energy Vision 2020 project by PacificCorp.

With completion of its $3.1 billion Energy Vision 2020 initiative, PacifiCorp announced this week that it has more than doubled its wind energy production in the United States, upgraded its wind turbine fleet, and more.

First announced in 2017, this initiative consisted of four new Wyoming wind projects that brought a combined 1,150 MW of new generating capacity online. Nearly all of PacifiCorp’s existing wind fleet in Wyoming, Washington and Oregon were re-powered along the way, with new nacelles and blades installed to increase output and extend the lifespan of another 1,000 MW. Some 140 miles of high voltage transmission were also built through Wyoming to support these efforts and modernize the grid

We can also look forward to the next set of projects by PacificCorp which were recently announced in response to their earlier RFP.

As part of its largest renewable energy solicitation ever — nearly 3,250 MW in all — PacifiCorp has added 19 projects to a shortlist of bids that it delivered to state regulators earlier this month. 

While the bids vary in size, scope, and targeted area, among other things they could provide:

1,641 MW of wind capacity in Wyoming

151 MW of wind capacity in Idaho

210 MW of solar (including 52.5 MW of installed battery capacity) in Oregon, the company’s largest investment to date in Oregon’s solar market

1,243 MW of solar (including 682 MW of installed battery capacity and one 200 MW standalone battery) in Utah

Each project could join PacifiCorp’s system by 2024. They were selected through a competitive all source request for proposals that began last year. 

Plus as we can see from Nevelyn's link and the below from the Casper Star Tribune...

Wyoming's biggest utility is closing the curtains on coal

The parent company to Rocky Mountain Power, the state’s biggest electric utility, announced Friday that its biennial Integrated Resource Plan is expected to include substantial investment in renewables — and no new investment in coal or natural gas. The 2021 plan will be finalized next week.

PacifiCorp intends to retire 14 of its 22 active coal units by 2030 and another five by 2040, with the remaining three shuttered shortly afterward. It would retain two coal units at Wyoming’s Jim Bridger power plant, converting them to natural gas peaking units in 2024.

With all of those coal units retiring there should be plenty of locations available for that nuclear reactor demonstration project.

Awesome  Nevelyn - Wyoming has been on a roll lately as far as good energy news.
