Why Rates Keep Rising
Capacity Auction Shock
PJM 2027-28 auction: $333.44/MW-day (new record, hit FERC price cap, still left 6,623 MW reliability shortfall). Northern IL faces capacity shortfalls by 2029.
Approved Rate Increases
ICC approved $606M delivery rate increase. ComEd supply rate jumped 47% YoY in Jan 2026 (6.55¢ to 9.66¢/kWh).
Grid Infrastructure Costs
Aging infrastructure requires billions in upgrades. These costs get passed directly to ratepayers through delivery charges.
Data Center Demand
AI and data centers are driving massive new electricity demand. PJM projects data centers will consume 13% of grid capacity by 2035, driving up prices for everyone.
Coal Plant Retirements
As coal plants retire under clean energy mandates, replacement capacity costs more. The transition is necessary but expensive for ratepayers.
Rate Projections
Based on 6% annual escalation — in line with recent Illinois rate trends.

| 2027 | 18.1¢/kWh | $181 |
