State Intelligence

Updated May 26, 2026

Utility Landscape

Rocky Mountain Power (PacifiCorp)

IOU

Most of Wyoming including Cheyenne, Casper, Laramie, and rural areas statewide

Dominant IOU in Wyoming with ongoing rate case activity tied to transmission investment and coal plant decommissioning timelines. WPSC scrutiny has intensified around wildfire liability cost recovery and the Energy Gateway transmission expansion.

Black Hills Energy (Wyoming Electric and Gas)

IOU

Northeastern Wyoming including Gillette, Sheridan, and portions of the Powder River Basin

Has pursued incremental rate adjustments linked to infrastructure upgrades and natural gas distribution modernization. Subject to WPSC review of its integrated resource planning amid evolving load growth in the Powder River Basin.

Cheyenne Light, Fuel and Power (Xcel Energy subsidiary)

IOU

Cheyenne metropolitan area and immediate surrounds in Laramie County

Small jurisdictional footprint but active in renewable energy procurement; filed for cost recovery related to solar additions. WPSC has examined fuel adjustment clauses carefully given natural gas price volatility.

Powder River Energy Corporation

coop

Northeastern Wyoming including Weston, Crook, Campbell, and Niobrara counties

Wholesale power supplied by Basin Electric Power Cooperative; faces retail rate pressures linked to Basin Electric's own cost structure. Engaged in distribution system hardening funded partly through USDA rural electric program grants.

Tri-County Electric Association

coop

Southeastern Wyoming including Goshen, Platte, and Niobrara counties

Member of Tri-State Generation and Transmission; navigating exit fee disputes as Tri-State restructures its wholesale contracts. WPSC oversight is limited but monitors retail rate filings.

Laramie Municipal Utilities

muni

City of Laramie, Albany County

Operates outside full WPSC jurisdiction as a municipal utility but coordinates on interconnection and transmission access matters with Rocky Mountain Power. Rate decisions made by city council with periodic infrastructure investment reviews.

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.
