Key Issues
- —
Rocky Mountain Power (PacifiCorp) general rate case before WPSC: contested issues include recovery of Energy Gateway transmission costs, allocation of wildfire-related liabilities across the multi-state system, and the appropriate rate base treatment of retiring coal units at Jim Bridger and Dave Johnston plants.
- —
Coal plant transition and resource adequacy: WPSC is examining whether RMP's integrated resource plan adequately preserves reliability as Wyoming coal capacity retires, with legislative pressure to slow retirements given the state's coal production interests and statutory provisions supportive of coal resources.
- —
Powder River Basin load growth and data center interconnection: emerging demand from data center and cryptocurrency mining operations in Campbell and Converse counties is straining local distribution infrastructure, prompting WPSC inquiry into cost allocation between new large loads and existing ratepayers.
- —
Wildfire cost recovery and insurance availability: following multi-state PacifiCorp wildfire litigation outcomes in Oregon, WPSC is evaluating whether Wyoming ratepayers should bear any portion of wildfire settlement costs and what prudency standards apply to utility vegetation management expenditures.
- —
Grid modernization and advanced metering infrastructure deployment: Black Hills Energy has sought WPSC approval for AMI rollout in northeastern Wyoming, raising issues around cybersecurity standards, data privacy protections, and the appropriate ratemaking treatment for capital and operational costs.
