Do you believe utility companies should be allowed to pass rising infrastructure costs to residential customers?

The Wyoming Office of Consumer Advocate will challenge Rocky Mountain Power's proposed 8.8% electricity rate hike, marking the third such request in three years. If approved, these consecutive increases would result in a 25% cumulative rise in rates for the utility's 150,000 customers since 2024.

Why it matters

The intervention highlights growing friction between state regulators and the utility provider over the cumulative financial burden placed on Wyoming residents. Rocky Mountain Power maintains that these adjustments are necessary to offset rising capital investment, maintenance costs, and ongoing inflationary pressures.

PacifiCorp reported $171 million in first-quarter net income for 2025, a 46% increase compared to the same period in 2024. This follows a $53.9 million rate increase previously approved by the commission in 2023.

The players

Rocky Mountain Power

This electric utility company serves approximately 150,000 customers in the state of Wyoming.

Wyoming Office of Consumer Advocate

This state office is responsible for representing the interests of utility customers during regulatory proceedings.

Wyoming Public Service Commission

This regulatory body oversees utility rate structures and determines final approval for rate increase requests.

PacifiCorp

This parent company of Rocky Mountain Power reported a 46% increase in first-quarter net income in 2025.

The details

The Office of Consumer Advocate, along with the Wyoming Industrial Energy Consumers and a consortium of irrigators, has formally intervened to oppose the rate hike. They intend to file testimony on September 29, 2026, aimed at securing a significant reduction or total elimination of the proposed increase.

Timeline

  1. Rocky Mountain Power requested a 21.6% rate increase in 2023.

  2. The 8.8% rate increase proposal was announced in May 2026.

  3. A public comment hearing was held in Casper on September 24, 2026.

  4. A public comment hearing is scheduled for Rock Springs on September 28, 2026.

  5. The Office of Consumer Advocate will file testimony regarding the rate analysis on September 29, 2026.

Market Landscape

This dispute reflects a broader struggle between state regulators and major utilities over the frequency of rate adjustments. It mirrors a trend where consumer advocacy groups are increasingly scrutinizing utility-requested hikes against the backdrop of rising corporate net incomes.

If the 8.8% increase is approved, Wyoming residents and businesses will face higher monthly utility bills beginning in 2027. This change would contribute to a 25% total increase in electricity costs for the state's consumers since 2024.

The takeaway

The ongoing series of rate increase requests by Rocky Mountain Power continues to place significant pressure on household and industrial budgets in Wyoming. Residents should monitor upcoming commission hearings to understand how these proposed utility costs might impact their long-term expenses.
