Why Rates Keep Rising
Capacity Auction Shock
MISO 2025-26 capacity auction: $666.50/MW-day (22x increase from prior year). Reserve margin dropped from 6.5 GW to 2.6 GW in two years. Ameren territory faces capacity shortfalls by 2031.
Approved Rate Increases
ICC approved $308.6M delivery rate increase (Dec 2024) plus $48.4M reconciliation increase (Dec 2025). Ameren intends to file another rate increase in 2026.
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.
