Monday, SEPTEMBER 15, 2025 |A federal judge has ruled in favor of PacifiCorp and its subsidiary Rocky Mountain Power in a case that could tap the electric utility’s Wyoming customers for yet more money. The judge handed down a court order last week allowing the calculation and modeling tool that Rocky Mountain Power used in 2023 to determine the rate hike on customers. PacifiCorp and its subsidiary, Rocky Mountain Power, sued state regulators for discounting expenses that the utility wants to pass onto customers. Earlier this year, customers in Wyoming saw their utility bill increase another 10 percent because of another 85-million dollar rate increase. The Wyoming Public Service Commission objects to the modeling tool that PacifiCorps uses to determine rates.
