CCGT Plants in Connecticut

Bridgeport Energy Location: CT Operator: Capital Power Configuration: 520-MW, 2+1 CCGT with V84.3A2 gas turbines Operation: 1998-1999 Fuel: natural gas, oil HRSG supplier: Vogt T/G supplier: GE EPC: Duke/Fluor Daniel Quick facts: In Sep 1997, Summit Energy Group (SEG) closed on Bridgeport Energy, a merchant plant venture with United Illuminating Co and Duke Energy. SEG negotiated and drafted the EPC contract, O&M Agreement and Project Coordination agreement. In total, 22 contracts were signed over a period of less than 6mos allowing construction to start on 15 Sep 1997. The plant began simple-cycle operation in Jul 1998 and combined cycle operation in Jun 1999. This was the first 2+1, V84.3A2 reference in the USA. The permitting also included an 11mi Southern Connecticut Gas lateral that interconnects to the Iroquois pipeline in Shelton, CT and once-through cooling facilities on Long Island Sound. A 115kV switchyard is at the site. Oil-firing capability was added in 2001 and in 2006, Duke sold the plant to LS Power, which in turn sold the plant to Dynegy in 2007. Capital Power acquired the facility from LS Power in Mar 2011 for $355mn and closing adjustments.

In 2002, the university issued an RFP for a greenfield CHP plant with peak output of 25 MWe, 200,000 pph of steam and 6,000 refrigeration tons of chilled water. A contract for the $80mn project was awarded in 2003. The electric load at UConn ranges from 8 to 22 MW. A major high-pressure natural gas line is located near the campus, so compression equipment was not needed. The university also has 300,000g of fuel oil as a backup. Ammonia injection is used to treat exhaust from the fired HRSGs prior to ducting into the 120ft stack. A small percentage of chilled water is used to cool gas turbine inlet air. The ST exhaust can also be directed to a dump condenser.

Wallingford Location: CT Operator: PPL Generation LLC Configuration: 5 X 46 MW LM6000 gas turbines Operation: 2001 Fuel: natural gas T/G supplier: GE EPC: Parsons Brinkerhoff Power, Barton Malow Design, Cianbro Corp Quick facts: This simple-cycle plant was built on the site of the town of Wallingford’s former municipal power plant. The project was the result of an initiative by the Connecticut Municipal Electric Energy Cooperative to develop new brownfield power plants.

Construction on the brownfield site began in Sep 2008, the unit was test-run 100 days after delivery, and the machine was synchronized on 1 Jun 2009. IST supplied an SCR. Waterbury generation cost about $120mn. In Sep 2008, SUEZ Energy signed an agreement to acquire FirstLight Power's portfolio of 15 facilities. Photograph courtesy of GDF SUEZ Re-posted 3 Mar 2012
