How to Identify Whether Your Current Illinois Energy Supplier Is Still Competitive at Renewal

The phrase 'quietly overcharging' might seem alarmist, but it's actually an accurate description of what happens when an Illinois business's energy contract auto-renews or when a supplier's renewal offer is accepted without competitive comparison. The supplier isn't doing anything illegal—they're simply charging what the market will bear for a customer who isn't actively shopping.

Supplier renewal offers are typically positioned as a 'convenient option' or even a 'loyalty discount.' What they rarely are is the best available market rate. Suppliers allocate their most competitive pricing to winning new customers and retaining high-risk accounts. Customers who seem unlikely to switch—because they're busy, haven't shopped before, or face an approaching expiration—tend to receive higher renewal rates.

The Benchmark Question

The single most important question to ask about your renewal rate is: 'How does this compare to what I could get from competing suppliers if I ran a competitive RFP today?' Without that comparison, you have no basis for evaluating your supplier's renewal offer. A rate that sounds reasonable in isolation—$0.062/kWh—may be uncompetitive if the market is offering $0.050/kWh for similar contract terms.

These warning signs don't definitively prove your rate is uncompetitive—but each one should prompt you to get a market comparison immediately.

1. 1**You haven't gotten competing quotes in more than 18 months.** Market conditions change quarterly, let alone annually. If you haven't tested the market recently, you don't know where you stand.
2. 2**Your current supplier sent a renewal offer 'as a courtesy' without you initiating the process.** Proactive renewal outreach from suppliers typically happens when they're concerned about losing your account—which suggests competitors are offering better rates.
3. 3**Your supply rate is higher than the current ComEd or Ameren Price to Compare.** While this isn't a perfect comparison (PTC is variable and changes monthly), consistently being above or near the PTC is a strong indicator of an uncompetitive contracted rate.
4. 4**Your supplier's renewal rate is higher than your current rate.** A supplier attempting to increase your rate at renewal—without a clear market-based justification—is almost certainly not offering you competitive terms.
5. 5**Peers in your industry report energy rates significantly lower than yours.** Industry benchmarking through trade associations, peer networks, or energy broker market analyses can reveal gaps between your rate and what similar businesses are paying.

An effective supplier comparison before contract renewal requires a systematic approach that creates genuine competitive pressure. Here's the process.

Step 1: Determine Your Renewal Timeline

Find your contract expiration date and required notice period. Mark the notice deadline (typically 30–90 days before expiration) as the latest acceptable date for providing termination notice if you decide to switch. Begin your market comparison at least 60–90 days before that deadline.

Step 2: Gather Your Current Rate Information

Document your current supply rate structure: fixed or variable, rate per kWh, any capacity or ancillary pass-through provisions. This is your baseline for comparison.

Step 3: Request an Expedited Market Analysis

Contact an energy broker and provide your account information, usage history (12–24 months), current rate, and renewal timeline. A responsive broker can typically return competitive quotes from multiple suppliers within 24–48 hours. This comparison reveals immediately whether your current rate is competitive or not.

Step 4: Compare on Total Cost Basis

Compare your current renewal offer to competing quotes on a total annualized cost basis—not just rate per kWh. Account for any differences in contract terms (length, pass-through provisions, termination clauses) that affect total value.

Step 5: Negotiate With Your Current Supplier

Armed with competing quotes, approach your current supplier with the market data. Many suppliers will improve their renewal offer when presented with evidence that competitors are offering lower rates. This negotiation leverage is only available when you've done the market comparison work.

The switch-or-stay decision at contract renewal should be made on the basis of facts—not loyalty, inertia, or assumption. Here's the decision framework.

When Staying Makes Sense

• Your current supplier, when presented with competing quotes, matches or comes within $0.001–0.002/kWh of the best competing offer
• Your current supplier has demonstrated exceptional service quality or has specific capabilities (e.g., green energy tracking, detailed reporting) that alternatives don't match
• The administrative cost and effort of switching outweighs the financial benefit (typically only true for very small accounts or very small rate differences)

When Switching Makes Sense

• Competing suppliers offer rates more than $0.002–0.003/kWh below your current supplier's best renewal offer
• Your current supplier's contract terms at renewal are less favorable than competing alternatives (e.g., automatic renewal clauses, restrictive early termination)
• You've experienced customer service issues with your current supplier that haven't been resolved satisfactorily
• A competing supplier offers better contract terms (e.g., more flexible exit provisions, better green energy options) at comparable cost

Managing the Transition

If you decide to switch, your new supplier handles the enrollment process with the utility. Most Illinois commercial switches process within 30–60 days. Your energy advisor should manage this process and provide confirmation at each stage. There is no service interruption—ComEd or Ameren continues to deliver electricity throughout the transition.
