It was one of the first powerplants in Utah designed to feed an electrical grid rather than as a source of power of a single locality.
The Eklutna Power Plant, also referred to as Old Eklutna Power Plant, is a historic hydroelectric power plant on the Eklutna River in Anchorage, Alaska. Located about 5 miles (8.0 km) downstream of the more modern new Eklutna Power Plant, it was built in 1928-29 to provide electrical power to the growing city, and served as its primary power source until 1956. The facilities include two dams, a tunnel and penstock, and a powerhouse. The main dam, Eklutna Dam, located at the northwestern end of Eklutna Lake, was built in 1941 to replace a series of temporary structures built after an earthen dam failed before the plant began operation. The diversion dam, a concrete arch dam, is located 7 miles (11 km) downstream from the lake, and provides facilities for diverting water into the tunnel. The tunnel is 1,900 feet (580 m) long, and is terminated in a penstock, a structure designed to raise the water pressure. The powerhouse is a concrete-and-steel structure completed in 1929. The diversion dam removal was completed in 2018 to allow for the passage of salmon.
The Ellsworth Power House and Dam, the latter also known as the Union River Dam, is a hydroelectric power generation facility on the Union River in Ellsworth, Maine.

The powerhouse is a Renaissance Revival building located at the western end of the dam. The power plant, built in 1907, was one of the first peaking power plants built in the state, and the hollow concrete dam is one of the highest Ambursen-type buttress dams ever built. The facility was listed on the National Register of Historic Places in 1985.
