With a heat wave expected to hit Illinois and Missouri in the coming days, Ameren is sharing steps customers can take now to stay safe and cool while keeping energy costs in check.
The utility says it constantly invests in the energy grid across both states to ensure it remains reliable and resilient even during extreme weather conditions.
In addition to measures Ameren has taken, officials say there are simple ways customers can prepare or adjust their habits when heat waves hit.
For instance:
Run ceiling or box fans with your air conditioner, you can raise the thermostat 3 to 4 degrees without sacrificing comfort
Closing blinds or drapes with white backings can cut indoor heat gain by up to one‑third
Grill outdoors or use small appliances like air fryers or slow cookers to reduce excess kitchen heat
Smart or programmable thermostats automatically adjust settings when you are away, saving the average household about $180 per year.
Income-qualified customers may be eligible for federal and state assistance such as LIHEAP in Illinois or Missouri’s Summer Energy Crisis Intervention Program.
