Thanks for 100 Years of Service

Rocky Mountain Power Centennial Logo

The year was 1912. A gallon of gas cost 7 cents and electricity was 15 to 20 cents a kilowatt-hour. The electric light bulb was 32 years old and 95 million people called the United States home.  

It also was the year that four electric companies merged to become Utah Power & Light. The new company served 39,700 customers in 130 communities.

Thanks to thousands of customers and employees, Rocky Mountain Power today delivers reliable electricity at a fraction of those 1912 prices to more than 1 million homes and businesses. Along with our sister company Pacific Power, we have 74 generating plants, including thermal, hydroelectric, wind and geothermal units, more than 61,500 miles of electric distribution line, and 16,200 miles of transmission line.  

We’ve seen a lot of change in 100 years, but through it all there’s been one constant – you, the customer. We value your business and the partnerships we have with the communities we serve.

We’re as committed today to delivering safe and reliable electricity as we were in 1912. We’ll continue to invest in new and improved ways of doing business to manage costs and improve our service to you. Thanks to you we’re planning on being around for many years to come.
