Commonwealth Edison Co. (ComEd) announced in March that it was beginning its massive 10-year, $2.6 billion grid modernization project, which will affect the electricity utility’s entire service area.

In a news release, ComEd said it plans the following improvements to be completed by the end of the first quarter:

1. Replace or reinforce utility poles at approximately 250 locations, to help maintain the grid and improve reliability in storm conditions.

2. Replace or inject more than 506,000 feet of underground residential distribution (URD) cable — the electrical cable they bury under the ground in neighborhoods to take electricity to homes — in order to reduce the number of cable failures.

3. Other enhancements designed to improve performance and reduce service interruptions include lighting enhancements, installing nearly 600 distribution automation devices, replacing more than 32,000 feet of mainline cable, assessing manholes at 660 locations and testing 12 sections of cable.

Additional work planned throughout 2012 includes replacing or reinforcing utility poles at 1,400 locations, replacing or injecting more than 1.6 million feet of URD cable, performing additional lighting enhancements, installing more than 430 distribution automation devices, trimming trees in approximately 2,300 locations, replacing more than 15,000 feet of mainline cable, conducting testing on nearly 100 sections of cable and assessing manholes at more than 3,200 locations.
