Xcel Energy (NYSE: XEL) is a major U.S. electricity and natural gas company with regulated operations in eight Western and Midwestern states.

The first predecessor company for Xcel Energy’s system in Colorado was incorporated 147 years ago on Nov. 13, 1869, as the Denver Gas Co.; this was seven years before Colorado achieved Statehood. Denver Gas did not begin providing service to customers – gas manufactured from coal retort – until late 1870, when it completed installation of two miles of line from retort houses near 18th and Wewatta streets. Through more than 100 mergers and acquisitions over the early years, the power company emerged as Public Service Co. of Colorado in 1924.

The original founders of the company included William N. Byers, founder of the Rocky Mountain News; Col. James Archer, a merchant and first president of the company; Louis Bartels, a merchant, rancher and banker; Walter Scott Cheesman, a railroader and water utility founder; John Evans, a medical doctor, builder of railroads and founder of the University of Denver; David Moffat, a banker and railroad builder; Lewis N. Tappan, a merchant; and D. Tom Smith, a freighter. Many of these individuals also were tied to the Denver Press Club.

In 1996, Public Service Co. of Colorado merged with Southwestern Public Service Co., based in Amarillo. That merger later was followed by one with Northern States Power Co., based in Minneapolis. Although Xcel Energy remains as the parent company name and brand for the eight-state entity, the company still operates to this day legally as Public Service Co. of Colorado. Xcel Energy provides a portfolio of energy-related products and services to 3.5 million electricity customers and 1.9 million natural gas customers through its regulated operating companies. Company headquarters are located in Minneapolis.
