Interstate 25 passes through eastern reaches of Fort Collins between Exit 265 and 271. The city rests at an average elevation of 5,000 feet above sea level and is perhaps best known as the home of Colorado State University, one of the largest universities in the state. Its weather is relatively moderate, with nearly 300 days of sunshine and approximately 14.5 inches of precipitation (rainfall and snowfall combined) annually.
Fort Collins is "The Choice City," and it was incorporated as a town in 1873, only nine years after it was founded as a military fort in 1864. Explosive growth increased the population from an estimated 126,848 in 2003 per the official city web page to 169,810 as recorded in the 2020 U.S. Census.
As part of its governmental services, the city of Fort Collins provides electricity for its residents. Along with three other regional municipalities (Estes Park, Longmont and Loveland), the city is part of the Platte River Power Authority. This authority transmits hydroelectric power generated through the Western Area Power Administration, and it also has generating facilities in the Front Range, in Craig (coal fire) and in Medicine Bow, Wyoming (wind turbines).
