what happened

According to TradingView, citing a ComEd press release, the Illinois Commerce Commission (ICC) approved the Grid Reliability Infrastructure Transformation (GRIT) project. ComEd received a Certificate of Public Convenience and Necessity (CPCN), which allows a utility to build major infrastructure after public review of the need, design and benefits.

The project includes four underground 138kV transmission lines and one new substation, forming a ring that links three substations. Power can be rerouted along alternative paths during faults, which should reduce the number and length of outages. Construction starts this fall, with completion and service planned for the second quarter of 2029.

ComEd says the project responds to growing demand, including from several large-load customers that have arrived in the Wood Dale and Elk Grove Village areas.

why it matters

For markets this is mainly a local infrastructure story. It matters for Exelon, the parent of ComEd, and for investors tracking regulated grid spending in areas where power demand is rising quickly, such as data center hubs.
