A ComEd Success Story• GEER contract signed w/ SSEP 8/6

– Conceptual design begins• First GEER meeting w/ ComEd 8/10

– Concept presented• Signed contract w/ ComEd 11/3• Kick-off meeting held w/ all suppliers 1/12• Site relocation from Lombard to Crawford 2/8• First TM2500 to test at SSEP 4/2• Begin site civil work at Crawford location 4/4• First TM2500 trailer arrives Chicago 4/27• Last TM2500 trailer arrives Chicago 5/23• 5 x TM2500 produce 100+ MW !!!! 6/1

From Concept to Full Power in just 10 Months !!!From Concept to Full Power in just 10 Months !!!


Next stop… Ireland• All five units installed at ComEd will be disassembled,

and shipped via RO/RO ship to Cork, Ireland in earlySeptember

• Will be used on a peaking basis to offset winter peakdemands

• The units will arrive Ireland in late September, and willbe split between two sites– 3 units will be located at the Aghada Power Station, near Cork– 2 units will travel north, to the town of Tawnaghmore

• All five units will be converted to 50 Hz. upon arrival,and will operate on liquid diesel fuel

• Commercial operation date is October 27th, less than60 days after shutdown in Chicago


Summary

• Proven experience and reliability

• Fuel flexibility and 50/60 Hz versatility

• Low emissions

• Small footprint

• Quick set-up

• Easy to dispatch, operate, and maintain

• Supported by GE strength and service structure
