MS 0206 Rocky Mountain Power Company records 1876-1992 Rocky Mountain Power Company 338 boxes 619.5 linear feet The Rocky Mountain Power Company records (1876-1992) consist of reports describing the company's acquisitions of smaller companies from 1912 to 1938, as well as a history of the parent company's accomplishments in providing power to the intermountain area. Also included are diagrams for the construction of various area power plants. Collection material is in English. Organizational History

The Rocky Mountain Power Company, originally known as the Utah Power and Light Company, was organized in September 1912. At that time there were many individual companies and municipal power systems serving only a fraction of the area now served by Rocky Mountain Power. Service centered in urban areas and most places only had partial service. Between 1912 and 1938, Utah Power and Light bought or leased these small, independent power facilities to form a unified network of electric service to Utah, parts of Idaho, Wyoming, and Colorado. Expanded electric service encouraged the development not only of industry, but also the introduction of modern conveniences such as water heaters, refrigerators, and street lighting. Utah Power and Light also extended service to rural areas where farmers used electricity to pump irrigation water.

The Rocky Mountain Power Company records (1876-1992) consist of reports describing the company's acquisitions of smaller companies from 1912 to 1938, as well as a history of the parent company's accomplishments in providing power to the intermountain area. These reports not only offer insight into the history of Rocky Mountain Power, but also into the overall development of the power industry in Utah, Idaho, Wyoming, and Colorado. Also included are diagrams for the construction of various area power plants and equipment.
