Gas Turbine and Combined-Cycle Plants in the USA - Maryland
College Park Cogen
Location: MD
Operator: Suez Energy Generation NA
Configuration: 27-MW, 2+1 combined-cycle CHP with PG-10B gas turbines
Operation: 2004
Fuel: natural gas, No 2 oil
HRSG supplier: Deltak
T/G supplier: GE, Turbosteam
EPC: Whiting Turner, Syska Hennessy, Duke Engineering & Services
Quick facts: The College Park CHP is at the main campus of the University of Maryland which is used about 35,000 students and has peak electricity demand of about 40 MW and annual electricity consumption of around 230 GWh. In the winter, the CHP facility is used to heat over 150 building buildings on a 5mi heating system while the system delivers chilled water during the summer. The equivalent heating/chilling capacity is 82 MW (280,000 pph steam, 10,750 ton/hour cooling).

CPV St Charles
Location: MD
Operator: Competitive Power Ventures
Configuration: 725-MW, 2+1 CCGT with 7F.05 gas turbines
Operation: 2017
Fuel: natural gas
HRSG supplier: CMI
T/G supplier: GE
EPC: SNC
Quick facts: CPV and its partners Marubeni and Toyota Tsusho Corp broke ground on this $775mn project on 2 Dec 2014.

Hawkins Point
Location: MD
Operator: Suez Energy Generation NA
Configuration: 10.4-MW, 6+1 combined-cycle CHP with M1A-13A gas turbines
Operation: 2000
Fuel: natural gas
HRSG supplier: AGC Inc
T/G supplier: Kawasaki, Ewing
EPC: Lockwood Greene
Quickfacts: In Dec 1998, Trigen-Cinergy Solutions LLC signed a 15yr contract to install and operate this CHP plant at Millennium Inorganic Chemicals' Hawkins Point facility. Millennium, based in Hunt Valley, is the world's second-leading producer of titanium dioxide. Trigen-Cinergy was a joint venture of Trigen Energy Corp and Cinergy Corp and was later taken over by Suez. Total thermal efficiency is around 70% with team output of around 54,000 pph.

Rock Springs
Location: MD
Operator: Essential Power LLC
Configuration: 4 X 168 MW 7001FA gas turbines
Operation: 2002-2003
Fuel: oil
T/G supplier: GE
EPC: Frucon
Quick facts: This site was developed jointly by Con Edison Development (CED) and Old Dominion Electric Cooperative, each of which owned two machines. The site is permitted for two more turbines. In Dec 2007, Con Ed agreed to sell its sets as part of a large divestiture of its merchant capacity to AllCapital (US) LLC and Industry Funds Management Pty Ltd. This closed in May 2008. The four combustion turbines have inlet air cooling.

Westport GT
Location: MD
Operator: Exelon Generation
Configuration: 1 X 116 MW GG4AF gas turbine
Operation: 1970
Fuel: natural gas
T/G supplier: Pratt & Whitney
Quick facts: All steam-electric units at Westport are now retired. These began going online in 1940. The peaking unit went online in Feb 1969. This is a unique configuration with eight P&W GG4-7 gas generators coupled with four Worthingon ER-224 double-flow expander turbines. This allows for both operation at reduced loads and black-start capability. In the summer of 2013, Emerson Process Management completed a $30mn project to install its Ovation control system at the facility.
