Your thermostat already does a lot to keep you comfortable and conserve energy. But now Ameren Missouri Peak Time Savings program is here to help your thermostat do even more. By understanding how your home uses energy, the weather in your area, and your unique comfort settings, Peak Time Savings uses its cutting-edge technology to make your smart thermostat even smarter. Peak Time Savings easily fits your lifestyle to help you save the most while still keeping you comfortable.
How it Works
- Make sure that your home's cooling system is operated by a qualifying WiFi-enabled smart thermostat. (See our FAQ page for a list of qualifying smart thermostats.) Don't have a smart thermostat? You can purchase one at the Ameren Missouri Online Store and install it.
- Complete the Peak Time Savings program enrollment form online. You may also call 1.877.215.5752 for additional questions.
- You will receive a confirmation email from the Peak Time Savings program and then you are officially enrolled. You'll also receive $50 as a sign-up bonus within 4 weeks.
- On the rare occasions that demand on the electrical grid is exceedingly high - and only on Monday through Friday during the months of May through September - your smart thermostat will automatically adjust to circulate the already-cooled air in your home. These times are called 'events' and will only last a few hours before your smart thermostat adjusts back to your preprogrammed cooling settings.
- If you are enrolled in the Peak Time Savings program with a Sensi device your home will also take part in Energy Efficiency days. Energy Efficiency days use learned behavior to help you create energy savings.
- Within a month of the anniversary of your enrollment, you'll receive $25 in the form of a bill credit.

Frequently Asked Questions
If you’re on a TOU rate, you’re probably already trying to shift your energy use out of high-demand hours. With Peak Time Savings, the program will manage this energy shifting for you, cooling your home before high-demand hours start, then reducing your use during the more expensive hours.
Peak Time Savings Events
Events will not occur on weekends or holidays, except in the event of a system emergency. Additionally, you may choose to opt out of an event if it impacts your plans or comfort.
If you wish to opt-out of the event and adjust your thermostat settings, then you can call the Peak Time Savings program at 1.877.215.5752. Ameren Missouri reserves the right to remove participants from the Peak Time Savings Program or make the customer ineligible for the next annual incentive if they opt-out of three or more events in the year.
Daily Energy Efficiency Optimization
When Peak Time Savings sees an opportunity to help you save even more, it may set your thermostat above or below your settings by just a few degrees. The goal is for this change to be small so that you stay comfortable.
If you become uncomfortable, the first step is to make sure your thermostat schedule is set to temperatures that you prefer. Setting your thermostat schedule will help us understand your preferences. You can change your schedule any time.
You will be eligible for a $25 annual appreciation bonus paid each year that you remain in the Peak Time Savings program.
