Jo-Carroll is a co-op: there is no ARES choice
Why members cannot switch supplier
The 1997 Illinois Customer Choice law opened residential retail competition for ComEd, Ameren Illinois and MidAmerican customers in 2002. Rural electric cooperatives and municipal electric departments were explicitly excluded by the legislature.
If you live in Jo-Carroll Energy territory, your supply rate is set by the member-elected board, not by an ICC auction or an ARES.
What that means in practice
- One bill, one company: Jo-Carroll owns the wires AND the supply;
- Rate changes go through a public member vote, not the ICC;
- No Price-to-Compare, no Uniform Disclosure Statement, no slamming risk;
- Capital credits: any margin above cost is allocated back to members;
- If you move to ComEd or Ameren territory, you regain ARES choice.
