Capacity Charges Just Spiked. Now What?

ComEd customers across Northern Illinois are seeing massive increases in electricity bills due to new capacity market rates. These are pass-through charges — not markups — and they’re hitting hard, especially for high-usage businesses.
If your facility uses 500 kW, you could be facing $40,000+ in unexpected annual charges.
The good news? You can take back control — by securing a better supply rate and understanding your options now, before your next contract cycle.
