SUBMITTED BY: Brian Groth, Electric Utility Director
BACKGROUND:
The utility's current power provider, the Illinois Municipal Electric Agency (IMEA), has been providing services to the City since 2007 and electricity to Naperville since 2011. The IMEA serves 32 municipal electric utilities across the state by securing the required capacity and energy for its member communities. In addition to providing power, the IMEA also handles several administrative, legal, and regulatory services for the utility.
The City's contract with IMEA expires on Sept. 30, 2035. Planning to acquire adequate power to meet Naperville's needs and operational and administrative services beyond this timeframe is a multi-year effort.
