Mountain Island Hydro Station

Mountain Island Hydro Station is a four-unit generating facility with a capacity of 60 megawatts located in Gaston County, North Carolina. It was built in 1923 to meet the growing demand for electricity by homeowners in the Carolinas. At the time, electricity was largely used by industrial customers.

Riverbend Steam Station

Riverbend Steam Station was a 454 megawatt, coal-fired generating facility located in Gaston County, North Carolina. It was first built in 1929. The four-unit station was named for a bend in the Catawba River on which it was located. Riverbend was used as a cycling station and was brought on line to supplement supply when electricity demand was highest. Four gas-fired combustion turbine units were also housed on the site. The four gas-fired turbines were retired in October 2012. The power house and stacks were demolished in 2018, with remediation of the

. Latta was a successful traveling merchant through 1820. He then retired and turned his property into a cotton plantation consisting of 742 acres and 34 enslaved people. After Mr. Latta's death in 1837, his wife Jane sold the property to David Harry. In 1853, William Sample purchased the property; it was owned by the Sample family until 1922. Crescent Land and Timber, a subsidiary of Duke Power, then purchased the property because of its proximity to the Catawba River and the construction of the dam. It is now a museum.
