ComEd keeps cool
Commonwealth Edison this summer installed 50 sound-attenuated, diesel engine power modules at three Chicago metropolitan locations to cope with the seasonal increased demand for electricity.
The 50 Caterpillar Rental Power units were supplied by Patten Power Systems, a local Caterpillar engine dealer, which located and coordinated the delivery of the modules earlier this year.
The units supplied a maximum of 80 MW of continuous power to the ComEd grid, giving the utility valuable flexibility during periods of high demand.
Each of the Cat XQ1750 power modules supplied to the project is capable of supplying up to 1600 kW of continuous power, and was connected to a 2500 kVA transformer. The units were paralleled to the utility and tied into ComEd`s distribution system.
