Q & A
Related questions
- Does Ameren Illinois use the same suppliers as ComEd?
- Plug In Illinois filters offers by utility territory. Ameren MISO-zone ARES lists and supply benchmarks differ from ComEd PJM-zone offers even within Illinois.
- Can I shop Ameren gas and electric independently?
- Yes. ICC choice allows separate ARES enrollment for electric and a gas marketer for Ameren gas delivery accounts. Each fuel has its own contract term and supply benchmark.
- Who responds to outages in Springfield or Peoria?
- Ameren Illinois continues delivery, metering, and outage dispatch after an ARES or gas marketer switch. Supplier changes affect commodity pricing, not emergency response.
