But comprehensive results will not be formally announced by the company until October. Spencer Hall, a spokesman for PacifiCorp noted that the findings could change depending on how additional tests unfold in the coming weeks.

“It’s a continuing process with stakeholders that we’ve had going for more than a year at this point. We’ll have a preferred portfolio for the state and our service territory next month,” Hall told the Star-Tribune on Friday.

The results, outlined in an integrated resource plan, are collected every two years and updated annually. They could have big implications for Wyoming consumers relying on electric grids run by Rocky Mountain Power (a branch of PacifiCorp), not to mention the state’s miners employed at the company’s coal units.

Using the results, the company will craft a multi-year plan for its massive energy system with the goal of providing the lowest possible price for consumers and the most reliable grid. Striking that exact balance can be complicated. The company operates in six states, including Wyoming.

“It’s a hugely complex modeling process,” Godby said.
