The McWilliams Power Plant was PowerSouth’s first generating plant and was named after Maury A. McWilliams, the first board president, recognizing his untiring and faithful efforts in bringing about construction of the plant. The plant’s first two units began operation in the mid-1950s, and the third unit went online in 1959. Having used the plant to its full life expectancy, PowerSouth repowered the plant in 1996 to help meet future generation needs. The repowering process included the installation of a natural gas-fired 107-megawatt combustion turbine-generator and a heat recovery system that recycles exhaust heat to create steam. The steam is used by the plant’s original units to produce electricity. The repowered plant provides 156 megawatts.
Construction on the Vann Plant, adjacent to the McWilliams Plant, was completed December 2001.The plant – named after former President and CEO James A. Vann, Jr. – uses a combined-cycle process of natural gas and steam generation. The natural gas used to fuel the plant is delivered via a 61-mile, 20-inch pipeline that runs from Flomaton, Ala., to the plant site. The Vann Plant serves as base load generation for PowerSouth and the distribution members. It boasts a capacity of 595 megawatts. It was designed to incorporate the most environmentally friendly equipment available to generate affordable electricity, and it is PowerSouth’s cleanest and most efficient fossil-fired generating facility to date.
The Point A and Gantt Hydroelectric Power Plants combine for a generating capacity of 8 megawatts. Water is held in large reservoirs behind the dams with hydroelectric power plants below. The dams create strong water flows that move turbine blades and turn the rotor of an electric generator.
The Gantt Plant is located in Gantt, Ala., at the site of a former grist mill on the Conecuh River. The Point A Plant is approximately five miles downstream near the town of River Falls, Ala. Today, the plants are operated and monitored using modern technology from on-site control rooms or a centralized control room at McWilliams Power Plant. The hydro plants operate only when river levels allow an adequate supply of water to turn turbines.
