Hog Bayou Location: AL Operator: Calpine Corp Configuration: 246-MW, 1+1 CCGT with 7001FA gas turbines Operation: 2000-2004 Fuel: natural gas, oil HRSG supplier: Deltak T/G supplier: GE EPC: Bibb, Kiewit Quick facts: Hog Bayou was built in 22 months and was originally designed for cogeneration service with an adjacent paper mill, but the mill shutdown during construction.

McIntosh Location: AL Operator: PowerSouth Configuration: 1 X 110-MW gas turbine with CAES, 2 X 113-MW V84.2 gas turbines Operation: 1991-1998 Fuel: natural gas, CAES T/G supplier: Dresser, EMC, SWPC EPC: Gibbs & Hill, Harbert, SWPC Quick facts: On 31 May 1991, Alabama Electric Coop (now PowerSouth) commissioned the world's second CAES gas turbine system at McIntosh. This remains the only plant of its kind in the USA and one of only two such plants in the world. The CAES unit uses compressed air stored in a 19mn ft³ underground cavern to mix with natural gas in the combustion process, thereby reducing gas burn. Off-peak electricity is used to recharge the storage cavern making the technology one of the few demonstrated methods for "storing" electricity. Two simple-cycle machines were added at McIntosh in Jun 1998 and construction started on two more in Jun 2009. Photograph courtesy of

McWilliams Repower Location: AL Operator: PowerSouth Configuration: 159-MW, 1+3 CCGT with V84.2 gas turbine Operation: 1996 (steam units 1954-1959) Fuel: natural gas HRSG supplier: B&W T/G supplier: Siemens, BBC EPC: Stanley, Burns & McDonnell, Caddell Quick facts: This was an early, full CCGT repowering project using some very elderly steam sets. There were numerous challenges including site layout, thermal discharge limitations, different steam pressures and temperatures, and 40yr old pneumatic controls. Siemens built the GT and the DCS and Hamon added a cooling tower. The HRSG steam conditions matched those of the 25-MW Unit-3 steam turbine, but the smaller, lower-pressure turbines on Units 1 and 2 nedded a pressure reducing desuperheater spray (PRDS) control valve to adjust the steam pressure and temperature.

Morgan Energy Location: AL Operator: Calpine Corp Configuration: 850-MW, 3+1 CCGT with W501FD gas turbines Operation: 2003 Fuel: natural gas, oil HRSG supplier: Nooter T/G supplier: SWPC, Toshiba EPC: Burns & Roe, BE&K Quick facts: Morgan Energy Center is a combined-cycle cogeneration facility interconnected with TVA via a 161kV line to the General Motors Substation near Decatur. This was the first IPP to provide automatic regulation services to the TVA system. In addition to merchant energy sales, electricity and steam are sold to the adjacent BP Amoco chemical plant under a long-term contract expiring in 2023. In Jun 2006, the plant was designated as a Star Worksite under the Voluntary Protection Program (VPP) of the U.S. Department of Labor's Occupational Safety and Health Administration (OSHA).

Tenaska Central Alabama Location: AL Operator: Tenaska Inc Configuration: 885-MW, 3+1 CCGT with 7001FA gas turbines Operation: 2003 Fuel: natural gas, oil HRSG supplier: Deltak T/G supplier: GE EPC: HB Zachry, Utility Engineering Quick facts: This is Tenaska’s second facility in Autauga County. Tenaska has an energy conversion agreement with Coral Power LLC for the power station’s entire production. The plant’s refinancing was named the North American Bond Deal of the Year in 2003 by Thompson's Project Finance International magazine and in 2005, Combined Cycle Journal presented five Best Practices awards for management, safety and operations to Tenaska’s Alabama plants.

Tenaska Lindsay Hill Location: AL Operator: Tenaska Inc Configuration: 845-MW, 3+1 CCGT with 7001FA gas turbines Operation: 2002 Fuel: natural gas, oil HRSG supplier: Deltak T/G supplier: GE EPC: Black & Veatch, Gilbert Industrial Corp Quick facts: This was the first large-scale, combined-cycle IPP in Alabama. Tenaska has an energy conversion agreement with Williams Power for the entire electricity output from the facility. Fuel owned and supplied by a Williams affiliate is converted into electricity and marketed by Williams throughout the Southeast region's wholesale power market. In 2006, Tenaska Lindsay Hill was again presented with a Best Practices Award from Combined Cycle Journal, this time for improving steam piping reliability during off-peak periods.

James A Vann Jr Location: AL Operator: PowerSouth Configuration: 539-MW, 2+1 CCGT with W501D gas turbines Operation: 2002 Fuel: natural gas HRSG supplier: Vogt T/G supplier: SWPC, MHI, Melco EPC: B&V, Metric Quick facts: Vann is adjacent to the McWilliams and operates baseload. Construction began in Jan 2000 and the plant was dedicated on 4 Dec 2001. Natural gas is delivered through a 61mn, 20in pipeline from Flomaton AL. Photograph courtesy of
