Salt Lake County Electrical Plan Task Force October 2009 Douglas N. Bennion, P.E. Vice President Rocky Mountain Power 1
Rocky Mountain Power s Bright History In 1881, Salt Lake City became the fifth city in the world to have central station electricity, behind only London, New York City, San Francisco and Cleveland. Utah Power & Light, as the company was first known, was formed in 1912 from several small electric companies in Utah, Idaho and western Colorado 2
Early Growth in the Region Purchased L.L. Nunn s Telluride Power Co. in 1912, including facilities in Utah, Idaho and Colorado. From 1913-1915, purchased three other large power companies in Utah and Idaho. Over the next ten years, acquired additional electric utilities, mostly small enterprises. By 1922, the company operated forty generating plants with an installed capacity of 224,000 kilowatts. 3
Expansion of Electrical System Only 30 percent of American industry was run by electricity in 1912; up to 70 percent by 1929. Residential electric service took hold more slowly, with many rural areas still without electric utility service into the 1930s. UP&L continued to expand its service area and acquire new generation resources from the 1920s through the 1960s. Began work in 1959 on a major transmission line to bring power generated at Arizona s Glen Canyon Dam to Utah customers. From 1960s through early 1980s, constructed new coal-fueled power plants in Utah and Wyoming. Number of customers increased from 282,000 in 1968 to 500,000 in 1984. 4
PacifiCorp - Today PacifiCorp was formed in 1984. PacifiCorp merged with Utah Power & Light in 1989. PacifiCorp was acquired by Scottish Power in 2000. PacifiCorp was acquired by MidAmerican Energy Holdings Company in 2006. 5
PacifiCorp Business Units Rocky Mountain Power delivers electricity to customers in Utah, Wyoming and Idaho. Pacific Power delivers electricity to customers in Oregon, Washington and California. PacifiCorp Energy includes the company s electric generation, commercial and energy trading functions and coal-mining operations. 6

The Challenge 12
Generation Resources Managing customer power costs in the face of growing load and peak demand. Increasing environmental compliance costs Emerging legislative mandates focused on renewable energy and climate change mitigation. Not In My Back Yard opposition to nearly all of our infrastructure investments. 13
As seen by the Customer Customer Right to receive safe, adequate and reliable service Reasonable prices without discrimination Freedom from monopolistic exploitation 14
As seen by the Utility Utility Obligation to serve all customers Prices set by regulators Prudent operating expenses passed on to customers Monopoly service territory Reasonable opportunity not a guarantee to earn a fair and reasonable return on its investments that serve customers 15
