State Intelligence
Updated Jun 1, 2026Utility Landscape
Rocky Mountain Power (PacifiCorp)
IOUMajority of Wyoming, including Cheyenne, Casper, and most of the state's eastern and central regions
Rocky Mountain Power is the dominant IOU in Wyoming and has faced WPSC scrutiny over wildfire liability cost recovery, transmission cost allocations under FERC Order 1000, and integration of the Energy Vision 2020 renewable portfolio. Recent rate proceedings have focused on cost pressures from its multistate system and cross-subsidization concerns raised by Wyoming industrial customers.
Black Hills Energy (Wyoming Electric)
IOUNortheastern Wyoming including Gillette, Newcastle, and surrounding communities in Campbell and Weston counties
Black Hills Energy completed a general rate case in 2024 resulting in a negotiated settlement with modest revenue increases tied to grid infrastructure upgrades. The company continues to navigate coal-dependent generation transition pressures given its service territory's proximity to the Powder River Basin.
Cheyenne Light, Fuel and Power (Black Hills subsidiary)
IOUCity of Cheyenne and immediate surrounding Laramie County area
As a combined gas and electric IOU, Cheyenne Light has been active before the WPSC on natural gas infrastructure cost recovery and electric system modernization. Rate cases have addressed data center load growth near Cheyenne driven by regional technology investment.
Tri-County Electric Association
coopSoutheastern Wyoming including Platte, Goshen, and Laramie counties
Tri-County is a distribution cooperative receiving wholesale power from Tri-State G&T. It has been navigating exit fee disputes and power supply transition issues as Tri-State restructures its member contracts under Colorado PUC-influenced reforms.
Powder River Energy Corporation
coopNortheastern Wyoming including Johnson, Sheridan, and parts of Campbell counties
Powder River distributes power purchased from Basin Electric Power Cooperative and has been engaged in rural broadband deployment initiatives under federal USDA ReConnect funding, an area of increasing WPSC interest regarding service overlap with telecommunications providers.
Lusk Municipal Electric
muniCity of Lusk in Niobrara County, southeastern Wyoming
As a small municipal utility, Lusk operates with limited WPSC oversight but has been identified in statewide rural electrification reliability discussions. Infrastructure aging and access to affordable wholesale power remain the primary operational concerns.
Key Issues
- —
Rocky Mountain Power (PacifiCorp) wildfire cost recovery and liability allocation: Following PacifiCorp wildfire litigation exposure in Oregon and California, Wyoming industrial intervenors and WPSC staff have scrutinized whether Wyoming ratepayers bear disproportionate system-wide cost burdens through multistate cost allocation methodologies.
- —
Coal generation retirement and resource adequacy planning: Wyoming's legislature and governor have maintained strong opposition to accelerated coal plant retirements; WPSC proceedings are evaluating RMP's Integrated Resource Plan proposals that contemplate retirement of coal units including the Naughton and Dave Johnston plants, creating political and regulatory tension over least-cost vs. reliability standards.
- —
Transmission development and FERC Order 1920 compliance: Wyoming hosts major wind resources in the southern tier and significant transmission expansion is under review, including the Transwest Express project; WPSC is monitoring how FERC's long-term regional transmission planning rule affects cost allocation to Wyoming utilities and ratepayers.
- —
Black Hills Energy data center and large-load interconnection: Rapid growth of hyperscale data center interest near Cheyenne is driving load forecasting revisions and infrastructure investment filings at both Cheyenne Light and Black Hills Wyoming Electric, with WPSC examining cost causation principles for large-customer-driven upgrades.
- —
Rural electric cooperative broadband deployment oversight: Cooperatives including Powder River Energy are deploying fiber broadband using federal grants, raising questions before the WPSC about pole attachment rates, right-of-way coordination with incumbent telecom providers, and whether broadband revenues should offset utility rate bases.
Upcoming
Estimated deadline for WPSC staff comments in Rocky Mountain Power's pending transmission cost allocation compliance filing related to multistate rate case adjustments; exact scheduling order anticipated from the Commission in summer 2026.
Estimated WPSC technical conference on Black Hills Energy / Cheyenne Light large-load interconnection policy, anticipated following completion of Commission-ordered staff investigation initiated in late 2025 regarding data center service agreements and cost allocation frameworks.
Estimated filing deadline for Rocky Mountain Power's next biennial Integrated Resource Plan update before the WPSC, expected to address updated coal retirement schedules, wind and battery storage additions, and Wyoming-specific resource adequacy commitments under legislative scrutiny.
Estimated WPSC evidentiary hearing on Tri-County Electric Association's wholesale power supply transition filing, addressing exit fee settlement terms with Tri-State G&T and proposed new power purchase arrangements; intervenor testimony deadlines expected in October 2026.
