The Gould Street Generating Station was a former 100 MW electric generating plant operated by Exelon that was located on Gould Street in south Baltimore, Maryland, USA. The plant was adjacent to an elevated section of freeway I-95 and was south of the Riverside neighborhood and west of the Locust Point neighborhood of Baltimore. The plant site, located on the shore of the Middle Branch of the Patapsco River, was used for the generation of electric power for over one hundred years before being shut down on June 1, 2019. The site was purchased by Greenspring Realty Partners, Inc. for $3.1 million in December 2019. Demolition began in October 2020. The original brick buildings, the large storage tanks behind them, and other minor structures on the southwest portion of the property were demolished as of March 2021, but as of April 2022 the larger steel building to the northeast on the property remains. A large portion of the property was acquired by Weller Development in July 2021 and the future of the remaining structure and the property is not known.
Neptune Bank Power Station was a coal-fired power station situated on the River Tyne at Wallsend near Newcastle upon Tyne. Commissioned in 1901 by the Newcastle upon Tyne Electric Supply Company, the station was the first in the world to provide electricity for purposes other than domestic and street lighting. It was also the first in the world to generate electricity using three-phase electrical power distribution at a voltage of 5,500 volts.
The Waltham Gas Light Company was a historic industrial facility located at 2 Cooper Street in Waltham, Massachusetts. It was one of the oldest industrial complexes on the South Side of the city, with brick buildings dating to 1854–55, not long after the founding of the company. The Waltham Gas Light Company was founded in 1853 to provide natural gas for "illumination, fuel, and power" to the area. In 1886 the company added an electrical generation plant to the property, which lay in an area roughly bounded by the Charles River, the Boston & Maine railroad right-of-way, and Cooper Street, which now serves an access to the municipal parking garage just west of the company property. The company shut down in 1909, transferring its electrical business to Boston Edison, which still operates an electrical substation in a nearby former company building. The other company buildings were converted to other manufacturing uses, and were demolished in 2007.
The Pratt Street Power Plant — also known as the Pier Four Power Plant, The Power Plant, and Pratt Street Station — is a historic former power plant located in downtown Baltimore, Maryland, USA.

Oneida Street Station, also known as the East Wells Power Plant, was a power plant operated by The Milwaukee Electric Railway & Light Company. Constructed from 1898 to 1900, it was designed by architect Herman Esser in neoclassical revival style. The building is located in downtown Milwaukee, Wisconsin, at the Milwaukee River and Wells Street, which was once known as Oneida Street. The company began operating electric street cars in 1890. Their expanding network of streetcar and interurban railway lines were powered by several of their own power plants. As the company generated more power than they used, they sold the excess electricity, and, as Wisconsin Energy Corporation, eventually became the major supplier of power to eastern Wisconsin. The American Society of Mechanical Engineers (ASME) describes the plant as the "first central power station in the United States to be equipped and successfully operated with pulverized coal."

It started out as a substation in the early 20th century, supplying Walla Walla with electricity. It was one of the first substations that converted hydropower to electricity in Washington state and is a good example of industrial architecture in the 1900s. Today it is as much a symbol of Walla Walla’s history as it is of the ever-changing culture of Walla Walla.

The first generating station on the site was owned and operated by the Yorkshire Electric Power Company. Following nationalisation of the British electricity supply industry in 1948 Thornhill power station was operated by a succession of state owned bodies. The power station was redeveloped with new plant in 1915, 1925, 1932–37 and 1950–54. The coal-fired steam station was decommissioned in 1982, and was subsequently demolished. A gas turbine power station on the site was commissioned in 1998.

The Central Steam Heat Plant, commonly known as Steam Plant Square, or simply as the Steam Plant, is a historic building in Downtown Spokane, Washington. Originally built to provide steam heating to more than 300 buildings in Spokane's city center, the Steam Plant served that purpose until the 1980s, when it was no longer viable. In the 1990s, the Steam Plant and adjacent Seehorn-Lang Building were converted into Steam Plant Square, a commercial, retail and restaurant center. The conversion maintained many of the industrial steam plant structures such as furnaces, boilers, catwalks and pipe networks, which can still be seen and explored by visitors and patrons. The Steam Plant's pair of 225-foot-tall stacks have been a unique and iconic aspect of the city's skyline for more than a century, and are illuminated from their base at night. If the stacks were considered to be a building, they would rank as the third tallest in the city.
