Why Is My Ameren Bill So High?

Illinois businesses served by Ameren are seeing record increases in electric supply rates. The default utility supply rate — known as the Price to Compare — surged from just 8¢ per kilowatt hour (kWh) earlier this summer to over 12¢ in July 2025. That's a 50%+ price jump.

Key factors driving this spike include:

• Peak summer demand — cooling and equipment use strain the grid
• Higher capacity auction results — reliability premiums built into rates
• Fuel volatility — natural gas prices rose significantly
• Retired plants & outages — less available generation

If you're still on Ameren's default rate, you could be overpaying by thousands per year. The good news? URate lets you lock in a lower rate now.

URate vs. the Competition

URate was designed to make it easy for Illinois businesses — especially Ameren customers — to shop smarter for electricity.

Choose Energy and ElectricityRates.com offer rate tools and supplier marketplaces, but often rely on static ZIP-based quotes — not live pricing. Commercial Energy Group and similar brokers provide quote-forged offers with around a 24-hour turnaround, without guaranteeing access to live market-based rates. Many platforms emphasize residential or small-business plans, not tailored to practical commercial electric rates.

The Verdict

Behind the Bill: What You're Really Paying For

Ameren Illinois customers often ask why their bills seem to climb — even when usage stays steady. The answer lies in the many components that make up your total cost. Here's a breakdown that reveals where your money actually goes and why it matters.

1. Supply & Fuel: The Role of Natural Gas

One major factor driving energy prices is the cost of natural gas. Since many power plants rely on natural gas for generation, fluctuations in gas markets directly affect electricity supply rates. As prices climb, so does the supply charge passed on to Ameren Illinois customers.

2. Transmission Service: Powering the Grid

Electricity doesn't magically appear at your business — it travels across thousands of miles of infrastructure. Transmission service charges cover the cost of delivering power reliably across the grid. Ameren Corporation continually invests in transmission service upgrades to improve reliability, which reflects in your bill.
