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 create the most energy-efficient schedule for you and your family. 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.
- If you have not yet enrolled in eco+, complete your enrollment in the Peak Time Savings program by first accepting eco+ in your ecobee app. Next, follow the prompts in your ecobee app to identify yourself as an Ameren Missouri customer and finish enrolling in the Peak Time Savings program. If you have enrolled in eco+, go to your eco+ settings and enable your "Community Energy Savings". From there, you can follow the prompts to complete your Peak Time Savings enrollment. 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 now receive $50 as a sign-up bonus.
- On a daily basis, the eco+ will incorporate your preferences along with information about how your home uses energy, the local weather, and your billing information to create a more efficient schedule that will maximize your savings while maintaining your comfort.
- 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.
- Within a month of the anniversary of your enrollment, you'll receive $25 in the form of a bill credit.

Overall
Yes! Customers on TOU rates are encouraged to join the program. On days when a Peak Time Savings event is called, we reduce your electric consumption during hours where overall energy use is high, which typically align with TOU rate peak periods when electricity is more expensive.
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.
Event Questions
You can opt out of an event at any time by setting a hold on your ecobee or tapping on the eco+ icon. You can also 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.
