Ameren’s Summer Rate Hikes Leave Residents Reeling—Relief Expected This Fall
GraniteCityGossip.com, August 5, 2025

Granite City residents aren’t just sweating the summer heat, they’re sweating their electric bills. While Ameren initially projected an average 18–22% increase in monthly charges, many local households are reporting bills that have doubled or even tripled compared to last summer.
One O’Fallon, Illinois resident saw her bill jump from $900 to over $1,800 in July. Another customer reported a spike from $225 to $537, calling it “ridiculous.” Small businesses are also feeling the strain, with some struggling to absorb the unexpected costs.
What’s Causing the Surge?
Ameren purchases electricity from the Midcontinent Independent System Operator (MISO), which sets regional wholesale prices. This year, MISO’s capacity auction price skyrocketed from $30 to $666.50 per megawatt-day, a cost passed directly to consumers. Ameren does not profit from this increase, but the impact on customers has been severe.
When Will Bills Go Down?
Relief is expected October 1, 2025, when Ameren’s supply rate is projected to drop back to 8–9 cents per kilowatt-hour, down from the current 12+ cents. Until then, high usage during peak summer temperatures will continue to drive up costs.
What Can You Do?
Contact Ameren to ask about budget billing or payment plans.
Apply for assistance through programs like LIHEAP, Warm Neighbors Cool Friends, and the Supplemental Arrearage Reduction Program (SARP), which offers up to $1,000 per year for qualifying customers.
Reduce usage where possible: set thermostats a few degrees higher, use fans, and unplug unused electronics.
Bottom Line:
The “average increase” doesn’t reflect the reality many Granite City families are facing. With bills soaring well beyond projections, it’s clear that usage patterns and extreme heat are compounding the crisis. While October promises relief, many need support now—and it’s crucial to spread awareness of available resources.
