Who do I contact if I have additional questions?
If you have questions or require assistance, email the program at savings@amerenmissouri.com or simply call the Peak Time Savings Program at 1.877.215.5752.
I'm on a time of use (TOU) rate. Can I join the Peak Time Savings program?

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.

Peak Time Savings Events

What is a Peak Time Savings event?
The hottest summer days create heavy demand on the energy grid. On these days of increased need, the energy system may become strained, and getting energy to everyone who needs it can become inefficient and expensive. The Peak Time Savings Program empowers our customers to voluntarily assist with keeping energy service reliable and affordable for the whole community by reducing energy use when demand is highest.

The Peak Time Savings Program empowers our customers to voluntarily assist with keeping energy service reliable and affordable for the whole community by reducing energy use when demand is highest.
When could an event occur and how often?
Events can occur in the months of May through September. Typically, events are called in the late afternoon. Up to 15 events can be called each summer. Peak Time Savings Program events can last up to four hours. 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.
How do I know when an event is occurring?
The program will send an email to you let you know that an event is planned, usually the day before the event is scheduled. In an emergency, you may be notified no less than 6 hours before the event begins. The program will also send an email letting you know when an event is beginning and ending. During an event, you'll see a notification on your thermostat and in your mobile app.
Can I adjust my thermostat during Peak Time Savings Events?
The Peak Time Savings Program takes into consideration your comfort preferences and will always operate within your eco+ "Savings Slider" settings to make sure you and your family stay comfortable throughout the event. 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.
