How does commercial energy deregulation work in Illinois?

Illinois deregulated electricity in 1997, allowing commercial customers to choose their energy supplier while utilities continue delivering power. Businesses can select from competitive suppliers offering various pricing structures.

Which utilities serve commercial customers in Illinois?

ComEd serves northern Illinois including Chicago, while Ameren Illinois serves central and southern regions. Both utilities allow commercial customers to choose competitive suppliers.

What types of businesses benefit most from energy procurement in Illinois?

Manufacturing, retail chains, restaurants, office buildings, healthcare facilities, and any business with high energy usage or tight margins benefit from competitive energy procurement.

How do I know if my business is eligible for supplier switching in Illinois?

Most commercial and industrial customers can switch suppliers. Eligibility depends on your utility account type, rate schedule, and whether you're in a municipal aggregation program.

What's the difference between fixed and variable electricity rates in Illinois?

Fixed rates lock in a price per kWh for the contract term, providing budget certainty. Variable rates fluctuate monthly based on market conditions, offering potential savings but less predictability.

How long does it take to switch energy suppliers in Illinois?

The switching process typically takes 4-8 weeks from contract execution to your first bill with the new supplier, depending on meter reading cycles and utility processing.

Will switching suppliers affect my power reliability or outage response?

No. Your utility (ComEd or Ameren Illinois) continues to deliver electricity, respond to outages, and maintain the power grid regardless of your supplier choice.

What are demand charges and how do they affect Illinois businesses?

Demand charges are based on your highest 15-minute usage during the billing period. They can represent 30-50% of your bill and are the same regardless of which supplier you choose.

Can Illinois businesses choose their natural gas supplier too?

Yes. Illinois also deregulated natural gas, allowing commercial customers to choose competitive suppliers for gas while utilities continue delivery services.

What should I consider when comparing energy suppliers in Illinois?

Compare not just price, but contract length, early termination clauses, rate structure (fixed vs variable), supplier financial stability, and customer service reputation.

How do capacity charges work in Illinois energy bills?

Capacity charges pay for regional power grid reliability. ComEd customers pay PJM capacity costs, while Ameren Illinois customers pay MISO capacity costs. These charges vary by your peak usage patterns.

When is the best time for Illinois businesses to shop for energy contracts?

Start shopping 3-6 months before your current contract expires. This allows time for market analysis and competitive bidding without rushing into unfavorable terms due to time constraints.
