Smart Solar Billing (effective Jan 1, 2025). New solar customers receive export credits applied to supply and transmission charges only — not delivery. Credits roll over monthly and settle at avoided cost at end of annual cycle. Legacy customers who completed installation by Dec 31, 2024 retain full retail net metering for the life of their system. Supply rates are elevated (9.5–10.5¢/kWh) through May 2026 due to the 2024 PJM capacity auction spike; total all-in residential rate is approximately 15–16¢/kWh including delivery. A CEJA Carbon-Free Energy Resource Adjustment (CFRA) credit of ~4¢/kWh partially offsets supply costs for non-solar customers. ComEd launched a new Delivery Time-of-Day (DTOD) rate in February 2026 offering set delivery pricing across four daily time periods.
