Thank you all for your speedy responses,
The Silversprings NIC installed in the meter is part of the 300 (314 to be exact, FCC ID: OWS-NIC514) Series which supposedly will support the Zigbe Smart Energy profile 1.1

Every time i call ComEd, they pass me to their "Smart Meter" department where the people only know general knowledge. as for the model, i purchased and installed the upgrade module as well as updated my firmware to match the ZS platform.
