Stairs Station Hydroelectric Power Plant Historic District, Historic hydroelectric plant in Big Cottonwood Canyon, US.

Stairs Station Hydroelectric Power Plant is a two-level powerhouse in Big Cottonwood Canyon, about 8 miles southeast of Salt Lake City. Built in 1894–1895 in the Second Renaissance Revival style, its lower level houses generating equipment and its upper level formerly held switchgear. The powerhouse is the only remaining building of the plant, which also included a switchyard, penstocks and a pipeline.

The facility was built in 1894-1895 to supply electricity to Salt Lake City and played a role in the early electrification of the region. The project came from the need to use water from the mountains and provide modern energy sources for the growing city.

The powerhouse was designed by Robert M. Jones for his Big Cottonwood Power Company, which in 1895 contracted to supply power to the Salt Lake and Ogden Gas and Electric Company. The two-level Second Renaissance Revival building put generating equipment below and switchgear above, a layout visitors can still read in the structure.

The site sits in a mountain canyon, so weather and road conditions vary by season. The best time to explore is during warmer months when the access roads are easily passable.

The four original Pelton wheels were replaced by a single Francis turbine rated at 1.2 megawatts, so the generating equipment inside is not the 1895 set. The penstock is about 1,750 feet of half-inch steel, and the operator's house that once stood on the site was demolished at an unknown date.
