Description | A proposed 900-megawatt power generation project at Seminoe Reservoir in Carbon County, Wyoming. The project faces potential cost increases due to restrictions aimed at protecting the local bighorn sheep herd, which could make the project infeasible. The company plans a five-year year-round construction starting in 2027 but seeks relief from seasonal construction restrictions to avoid doubling the construction duration and adding approximately $1.62 billion to the cost. |
