Do you trust that your utility provider's requested rate increases are reasonable for your household?
Wyoming’s Office of Consumer Advocate filed a recommendation on September 30, 2026, to decrease electricity rates by 2.9%, opposing Rocky Mountain Power's proposed 8.8% rate hike. The decision follows a multi-year period of recurring double-digit rate increase requests and approvals.
Why it matters
Operators face significant uncertainty as the regulator balances the utility's infrastructure maintenance and wildfire insurance costs against claims of overstated expenses. This conflict determines whether local businesses will see energy costs stabilize or continue to face the rising overhead seen since 2023.
The Office of Consumer Advocate proposes a 2.9% rate cut, challenging an 8.8% increase request from Rocky Mountain Power. This follows a trend of utility cost volatility, including a 10.2% rate hike approved in April 2025 and an 8.3% increase in 2023.
The players
Rocky Mountain Power
An electric utility provider that maintains regional infrastructure and operates under the jurisdiction of the Wyoming Public Service Commission.
Wyoming Office of Consumer Advocate
A regulatory oversight body that represents the interests of utility customers by analyzing rate proposals and conducting formal opposition in contested cases.
Wyoming Public Service Commission
The state regulatory agency responsible for setting utility rates and adjudicating disputes between service providers and consumer advocates.
The details
The Office of Consumer Advocate reached its recommendation by scrutinizing line-item expenditures and benchmarking them against wholesale power price trends. Rocky Mountain Power argues the 8.8% increase is necessary to cover critical investments and rising wildfire insurance, while the advocate claims these cost estimates are overstated. The utility's proposal currently includes a 2.8% credit stemming from the sale of its Washington service area, which the regulator must now evaluate against the utility's total revenue needs.
Timeline
The Public Service Commission approved an 8.3% rate increase in 2023.
The Public Service Commission approved a 10.2% rate increase in April 2025.
Rocky Mountain Power submitted its request for an 8.8% rate increase in May 2026.
The Office of Consumer Advocate filed its recommendation on September 30, 2026.
Rocky Mountain Power must submit a rebuttal to the recommendation by October 28, 2026.
Market Landscape
The current rate fight in Wyoming follows the standard procedural path of the utility rate case contested process. This regulatory framework governs how state commissions balance corporate infrastructure investment requirements against consumer protection.
Businesses should review their energy budget projections as the outcome of this case will set the primary utility rates for the near term. Owners should prepare for a potential rate reduction or a continuation of recent high-percentage annual cost increases.
The takeaway
This case highlights the growing friction between utility infrastructure spending and regulatory scrutiny over consumer costs. Operators should monitor the October 28 deadline for the utility's rebuttal filing to gauge the likelihood of a settlement versus a prolonged December hearing.
What happens next
Rocky Mountain Power is required to file a rebuttal to the Office of Consumer Advocate's recommendation by October 28, 2026. If the parties do not reach a settlement, the Public Service Commission is expected to conduct a formal hearing on the contested case in December 2026.
