Illinois utility tries using electric school buses for bidirectional charging
The largest electric utility in Illinois is rolling out a program for a vehicle-to-grid (V2G) electric school bus-charging pilot with three Chicagoland school districts, testing the functionality of bidirectional chargers that could make energy cheaper for customers and reduce grid load.
The Commonwealth Edison Co. (ComEd) announced in September that it would begin the testing phase of its novel V2G electric school bus charging pilot, the first of its kind in northern Illinois, coinciding with the beginning of the school year.
The utility began testing with the River Trails, Troy, and Wauconda school districts-which have all had electric buses for more than two years-in northern Illinois. It is currently collecting data from bidirectional chargers, EV chargers that flow energy both ways. Its testing will determine how the chargers and buses can best transfer energy when parked and plugged into the grid.
