Alcoa Power Generating
Alcoa Power Generating, Inc. is a subsidiary of Alcoa Inc., headquartered in Pittsburgh, Pennsylvania. Its three divisions were independent subsidiaries before being consolidated into Alcoa Power Generating, Inc. (APGI). These three projects have produced hydroelectric power and manage impoundments which also provide flood control; recreation, residential and business opportunities; and wildlife habitat.
The APGI Yadkin Project managed a 38-mile section of the Yadkin River, plus tributaries, in Piedmont North Carolina and included four dams, powerhouses and reservoirs, sold in February 2017 to Cube Hydro Carolinas. The counties of Davie, Davidson, Rowan, Stanly, and Montgomery border the Yadkin Project river and lakes. The dams owned and operated by APGI were the Narrows dam (completed in 1917), the Falls dam (completed in 1919), the High Rock dam (completed in 1927), and the Tuckertown dam (completed in 1962). The Narrows dam and powerhouse development is the only hydroelectric project listed on the National Register of Historic Places in North Carolina. The other three dam and powerhouse developments have been determined eligible for listing on the National Register.
At the Narrows, the Yadkin River flowed through a deep gorge for three and a half miles within the Uwharrie Mountains. Its potential for industrial development had long been recognized. In 1887, E.B.C. Hambley, a mining expert from England, came to Salisbury, North Carolina. He gained the backing of Pittsburgh industrialist George I. Whitney. Between 1899 and 1901, Whitney organized eight subsidiary companies and employed Hambley as his chief engineer. About a mile upriver from the Narrows, the Whitney Development Company nearly completed the granite Whitney Dam and a five-mile long diversion canal, and began construction of a powerhouse at Palmer Mountain before the company declared bankruptcy in 1907 and all work ceased. The massive canal remains today, while the Whitney Dam lies beneath the waters of Badin Lake. They have been determined eligible to be listed on the National Register. In 2017, Historic Salisbury Foundation board president Susan Sides said, "It was called one of the most unique dams in all history. It was referred to as the 'Niagara of the South.'"
In 1912, a French Company, L'Aluminium Français, acquired the assets of the Whitney Company. L'Aluminium Français decided against completing the Whitney project, and organized the Southern Aluminum Company to construct a 200-foot (61 m) high dam and powerhouse at the Narrows to power an aluminum plant which it would also build. West of the proposed smelter, the worker's village of Badin was planned and platted. The town was named in honor of the Southern Aluminum Company's president, Adrien Badin. The project faltered a second time as most of the French engineers returned to France during World War I.
In 1915, the Aluminum Company of America purchased the property. Plans once again were altered. The dam was redesigned and the new plans called for a brick powerhouse to be built on the east side of the river. The original powerhouse site on the west side of the river was abandoned and the partially completed building was dismantled to its concrete foundations. The original smelter site was also abandoned and a new smelter building was designed west of the Badin townsite. A devastating flood in 1916 caused damage and delays. When completed in 1917, the 185-foot (56 m) Narrows Dam was the world's highest overflow type dam. The Narrows Reservoir, commonly called Badin Lake, reaches a depth of 190 feet (58 m) and occupies 5,350 acres (2,170 ha).
To generate additional hydroelectric power, in 1919, the company constructed Falls Dam downriver of Badin and High Rock Dam upriver in 1927. High Rock Lake, at 15,180 acres (6,140 ha), was the largest lake on the Yadkin at that time. In 1929, the company's name was changed to Alcoa. In 1962, Alcoa built the Tuckertown Dam between High Rock and Narrows Reservoirs.
In August 2002, Alcoa temporarily suspended aluminum production at the Badin Works, laying off 377 workers. The electrode plant continued operating until 2007 when the plant shut down permanently. The dams continue to generate 215 megawatts of electricity annually which the company sells. During calendar years 2008, 2009, and 2010, the Yadkin Project generated an average of $7.73 million annually in net income, on an average of $29.46 million in annual revenues. In the year ending September 2013, APGI sold 964,216 megawatt hours, with revenue estimated at $30 million.
On July 11, 2016, Cube Hydro Carolinas, part of Cube Hydro Partners LLC, announced its purchase of the APGI power plants on the Yadkin River. Cube Hydro intends to improve the plants. APGI would still own 15,000 acres (6,100 ha) of land. On December 13, the Federal Energy Regulatory Commission approved the license transfer to Cube Yadkin Generation. The sale became official February 2, 2017.
