Rocky Mountain Power Residential Rates and Guidelines
Historical Utah power rates from Rocky Mountain Power, associated solar facts and what to expect from this utility company in the future.
Utah Power has a steady history of energy rate increases and decreases, although more price increases have occurred over the years. In this guide to Rocky Mountain Power costs, discover why coal power costs ebb and flow and what solar customers can expect.
Rocky Mountain Power and Fossil Fuels
As a locally managed, wholly-owned subsidiary of Berkshire Hathaway Energy Company, PacifiCorp (aka Rocky Mountain Power and Pacific Power) has become a leading western U.S. energy services provider. The largest grid owner-operator in the West, PacifiCorp, serves 1.9 million customers across 141,000 square miles in six western states, including Utah.
While Rocky Mountian Power has made efforts to reduce fossil fuels, coal-fired power plants still comprised 66 percent of Utah's electricity generation in 2018, making it the 12th largest coal-producing state that year.
Emissions of harmful waste come from burning coal such as carbon dioxide, sulfur dioxide, nitrogen dioxide sulfuric acids, arsenic and ash.
Rocky Mountain Power's Rising Rates
The rise in Rocky Mountain Power's rates comes as no surprise. A rising trend in energy costs is one of the reasons renewable energy production has developed significantly in Utah over the past two decades.
Rocky Mountain Power offers a tiered-rate system with different rate schedules for Summer and Winter. The more energy used, the more customers pay per kWh for electricity.
Each season has a low, mid and high tier for electricity rates, with rate increases for each threshold of energy use. However, homeowners with residential solar can achieve a greater degree of energy independence from these rate hikes by taking their homes solar.
What if someone told you that 15 years ago, you could have locked in the price you paid for gasoline? Would you have done it? Of course! Private solar power production is now providing the ability to lock in your energy costs for the next 25-plus years (and likely longer — many residential solar arrays last 40-plus years)!
Residential solar pulls customers down from the high-tier or mid-tier and enables them to earn energy credits, which covers the cost of high energy bills in the darker winter months. Through net metering and the Rocky Mountain Power solar program rate structure solar can help customers save money.

Rocky Mountain Power Solar Customer Charges Breakdown
Customer Service Charge
The customer service charge covers billing and grid connection. These services include mailing bills, meter maintenance and meter reading.
Power Factor Charge
A power charge, or demand charge, bills customers for the highest amount of energy used in a billing cycle. Utah measures this in 15-minute intervals. Individuals with solar power can minimize costs by running appliances during the day or opting in for battery backup.
Saving money on this charge may mean coming home on your lunch break and putting in a load of laundry or starting the dishwasher. Many appliances have delay timers, allowing machines to turn on mid-day on their own. Running fewer high-energy machines at once will also decrease the amount of this charge.
Expectations for the Future of Solar in Utah
As fossil fuels become increasingly scarce, the cost of energy production will increase. While rates go down some years, the long-term trend shows that utility rates increase over time.
Even utilities that have started adding renewable energy to their energy production charge more. Most utility companies charge a premium on top of their regular rate if the customer wants renewable energy.
