ComEd offers overnight EV charging rates as low as $0.034/kWh. Illinois has over 3,500 public charging stations statewide with rapid expansion along I-55, I-57, I-80, and I-90. Our calculator estimates your total EV savings factoring in fuel savings, maintenance reduction, the $100 EV fee, and available federal credits.

Frequently Asked Questions
How much do EV owners save in Illinois?
Average annual savings: ~$1,200 on fuel (electricity vs gas at IL prices), ~$800 on maintenance (no oil changes, less brake wear), minus $100 EV registration fee = ~$1,900 net savings per year. With ComEd's EV overnight rate ($0.034/kWh), fuel savings increase to ~$1,600/year. Over 10 years: $19,000+ in operating savings, plus the federal tax credit.
What is Illinois's EV registration fee?
Illinois charges a $100 annual registration surcharge for battery-electric vehicles. This is in addition to the standard registration fee (~$151). The fee is intended to replace lost motor fuel tax revenue. For comparison: a gas car driving 12,000 miles at 28 MPG pays ~$170/year in IL motor fuel tax ($0.39/gal), so the $100 EV fee is actually lower than the gas tax equivalent.
Does Illinois offer an EV rebate or incentive?
Currently, Illinois has no state-level EV purchase rebate or tax credit. The primary financial incentive is the federal tax credit: up to $7,500 for qualifying new EVs and $4,000 for qualifying used EVs (income limits apply). Some utilities offer EV-related programs: ComEd has the EV charging overnight rate and sometimes offers charger installation rebates. Check with your local utility for current programs.
How much does it cost to charge an EV in Illinois?
Home charging at standard ComEd rate: ~$0.14/kWh = $5.60 for a full 300-mile charge. With ComEd EV rate (overnight): ~$0.034/kWh = $1.36 for the same charge. Public Level 2: $0.15-$0.25/kWh. DC fast charging: $0.35-$0.50/kWh ($14-$20 for 300-mile charge). Monthly home charging cost: $25-$55 for average driving at standard rates, $10-$22 with the EV overnight rate.
Is Illinois's EV charging network adequate?
Illinois has 3,500+ public charging stations (2024) with strong coverage in Chicagoland and along major interstates. NEVI (National EV Infrastructure) funding is adding DC fast chargers every 50 miles along I-55, I-57, I-80, I-88, I-90, and I-94. Urban coverage is excellent; rural downstate coverage is still developing. Tesla Supercharger network is extensive, and most are now open to all EVs via adapter.
