ComEd electricity rates & savings

Understand your bill, compare rate plans, optimize EV charging, and model solar savings for ComEd customers. Gleam helps ComEd customers in northern Illinois compare Time-of-Day Pricing with the standard rate, charge an EV in the overnight window, and avoid the 1–7pm mid-day peak.

Peak & off-peak hours

Peak · 1pm–7pm every day (Mid-Day Peak)

Off-peak · 9pm–6am Overnight. Morning is 6am–1pm and Evening is 7–9pm; both are below Mid-Day Peak.

Illustrative timeline — exact windows vary by season and rate schedule.

Is the TOU or EV plan worth it?

If you drive 700+ miles/month and can charge overnight or on weekends, ComEd's time-varying rate often saves money — peak rates can run 4.6× off-peak. If most of your usage happens during peak hours (often late afternoon), TOU may cost more than a flat plan.

Solar & net metering

ComEd uses Illinois legacy retail or post-2025 DG rebate net metering. Solar/net-metering customers may be ineligible for some TOU schedules — verify with your utility before switching rate plans.

Example EV charging savings

Typical EV: 11,000 miles/year (3,143 kWh)

Scenario	Est. annual cost
Charge during peak ($0.28/kWh)	$894/yr
Charge off-peak ($0.06/kWh)	$194/yr
Estimated savings (off-peak vs peak)	$700/yr

Assumes 11,000 mi/yr, 3.5 mi/kWh, and 100% of EV charging at each rate tier. Real savings depend on your driving, charger, and schedule.

How these rates are built

Northern Illinois, including Chicago. Figures are supply plus distribution facilities for a single-family home without electric heat, not a full bundled bill (customer charge, metering, taxes, and other riders are extra). Standard summer supply 10.399¢/kWh plus distribution 6.228¢/kWh. Time-of-Day (Rate BEST, from June 2026) uses four periods every day. Hourly Pricing (Rate BESH) is a separate supply rate that changes every hour and is not modeled here. Customers on an alternative supplier cannot take ComEd supply Time-of-Day.

EV and time-of-use notes

Single-family non-electric-heat supply + delivery: Overnight 6.174¢ summer / 6.739¢ non-summer; Mid-Day Peak 28.446¢ summer / 26.551¢ non-summer. Supply is the same for every residential class; delivery varies by class. Registering an EV at Time-of-Day enrollment earns $2/month per vehicle, up to two vehicles, for 24 months. Leaving Time-of-Day or Hourly Pricing requires 12 months before you can return. Legacy net metering (interconnected before 2025 with no DG rebate) cannot enroll in Time-of-Day.
