McIntosh
Location: AL
Operator: PowerSouth
Configuration: 1 X 110-MW gas turbine with CAES, 2 X 113-MW V84.2 gas turbines, 2 X 224 MW SGT6-5000F gas turbines
Operation: 1991-2010
Fuel: natural gas, CAES
T/G supplier: Dresser, EMC, SWPC
EPC: Gibbs & Hill, Harbert, Siemens, Black & Veatch
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. These went commercial in Jan 2010 ahead of scheule and under budget. These machines were dedicated on 22 Apr.

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).
