Two things people get wrong about ComEd solar now
Current residential rates
ComEd residential rates are shown below, from the utility's published tariffs and the public Utility Rate Database. Rates vary by plan, season, and usage and change over time.
| Plan | Energy charge | Fixed / basic |
|---|---|---|
| Residential default supply (Price to Compare) plus delivery, single-family without electric heat | Supply about 9.66 cents/kWh (Price to Compare, early 2026; summer 2025 was 10.028 cents) plus distribution delivery about 6.23 cents/kWh, for roughly 15.9 cents/kWh combined before transmission riders and taxes | About $15.26/month customer and metering charge |
ComEd is a wires-only delivery utility in Illinois's deregulated market. The supply charge above is ComEd's default Price to Compare, an approved fixed pass-through that resets every few months (summer 2025 was 10.028 cents; early 2026 was 9.66 cents); customers may instead buy supply from a competitive supplier or municipal aggregation. The rate history is the bundled full-service price, that is, what a household on ComEd default supply actually pays; the lower headline number some sites publish also folds in delivery-only customers on competitive supply. Confirm current pricing on ComEd's rate pages before making decisions.
What Illinois changed about solar exports
Under the Climate and Equitable Jobs Act, Illinois ended full retail net metering for residential systems interconnected on or after January 1, 2025. ComEd now credits solar exports only at the supply (energy) portion of the rate, not the delivery, transmission, or tax portions, so an exported kWh is worth roughly half a retail kWh. A one-time smart inverter rebate of about 300 dollars per kW partly offsets this, unused credits roll over, and systems granted permission to operate before January 1, 2025 are grandfathered onto the old full retail netting.
Sizing solar for the new net metering
ComEd's rates have climbed about 35 percent since 2015, and a sharp 2025 supply increase pushed the residential average toward 18 cents per kWh. Higher rates make the solar you generate and use yourself more valuable.
The catch in Illinois is the export side. Since 2025 new systems earn only the supply rate for exported power, so surplus is worth far less than the power you offset directly. That points toward sizing for your own use and, for many homes, adding a battery. A one-time smart inverter rebate helps offset the change. Whether solar pencils out depends on your usage and roof, so get a site-specific quote.
What rising ComEd rates could cost you
ComEd rates have risen about 3.0% per year. Enter your bill to see what that pace of increase could compound to over time, and what you have likely already absorbed. This is an estimate, not a guarantee.
Estimate only. Projects your current bill forward at ComEd's historical average rate increase (3.0% per year, from EIA data); it assumes your usage stays the same except for any add-ons you select. Actual rates depend on your usage, rate plan, and the utility's future filings, and are not guaranteed. This is general information, not financial advice.

FAQ
How much have ComEd electricity rates gone up?
ComEd's average full-service residential price rose from about 13 cents per kWh in 2015 to about 18 cents in 2025, an increase of roughly 35 percent, per EIA Form 861 data, with a sharp jump in 2025.
Does ComEd still have net metering?
Yes, but the rules changed. For residential systems interconnected on or after January 1, 2025, Illinois credits exports only at the supply portion of the rate, not delivery or transmission, so exports earn roughly half a retail kWh. Systems granted permission to operate before 2025 are grandfathered on full retail netting.
Why is my ComEd supply rate different season to season?
ComEd is a delivery utility. Its default supply is a Price to Compare that resets seasonally (it was 10.028 cents in summer 2025 and 9.66 cents in early 2026), and you can buy supply from a competitive supplier instead. Only delivery is fixed by ComEd.
Is solar worth it with ComEd?
Rising rates make the power you offset directly worth about 18 cents, which helps, but exported power now earns only the supply rate. The economics favor a system sized to your own usage, often with a battery. Get a site-specific quote rather than a general estimate.
