US utility Commonwealth Edison (ComEd) has announced a plan to expand a 765 kV substation to add 2.45GW of renewables in Illinois. 

After completion, the substation will enable five renewables projects, with a combined wind capacity of 2GW and solar capacity of 450MW, to connect to the Illinois electric grid and the PJM energy market. While the five renewables projects all include wind, two, the Heritage Prairie and Osagrove Flats projects, will include solar as well as wind generation capacity, with 300MW and 150MW of PV respectively.
