As of Oct. 1…
ComEd’s new electricity price is:
Ameren's new electricity price is:
4.715¢/kilowatt-hour (kWh) for the first 800 kWh;
4.476¢/kilowatt-hour (kWh) for usage beyond 800 kWh
- These are the rates of Illinois' two major electric utilities. Their prices differ because the supply rates are set by different energy markets with different rules. These utilities serve customers living in set geographic territories: ComEd covers the northern third of Illinois, roughly; and Ameren the southern two-thirds of the state. Note: People living in ComEd territory cannot switch to Ameren, and people living in Ameren territory cannot switch to ComEd.
- These rates will be in place through May 2020. This ComEd/Ameren price is called the “price to compare” because this is what you use to make an apples-to-apples comparison with alternative supplier offers.
- ComEd’s price includes a supply rate (5.998 cents per kWh) PLUS a transmission services charge (1.226 cents per kWh).
- Ameren's price includes a supply rate (3.485 cents per kWh for the first 800 kWh; 3.246 cents per kWh for usage beyond that); a transmission charge (1.172 cents per kWh) and a Supply Cost Adjustment (0.058 cents per kWh).
- These rates DO NOT include the Purchased Electricity Adjustment (PEA), a per-kWh credit or debit that changes monthly.
- These are supply prices. Your bill also has "delivery charges"—fees the utilities charge you to deliver the electricity to your home. Supply charges take up about a half to two-thirds of your bill, with delivery charges and taxes taking up the rest. (Note: ComEd and Ameren do not make a profit on supply charges. They simply pass along the market prices, with no markup. However, both companies are allowed to proft off of delivery charges. Those rates are set by a formula in a process overseen by the Illinois Commerce Commission.)
- If you’re with an alternative electricity supplier—either a company chosen by you or by your community—compare the price you’re paying with your utility’s rate above. WARNING: In this market, it’s likely the utility rate is your best bet.
