Who do I contact if I have additional questions?
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.
How can I override the Energy Efficiency days schedule?
We work with your thermostat to save energy, but if you want to adjust the temperature on your setpoint, you can! Most setpoint adjustments will last two hours, then your Energy Efficiency Day schedule will resume. If your thermostat is in schedule-off mode, your override will be in effect until we send the next update.
Can I participate in Peak Time Savings and not Energy Efficiency Days?
No. At this time Sensi customers in the Peak Time Savings program are required to also participate in Energy Efficiency Days.
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.
Why are Peak Time Savings events good for the community?
The hottest 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.
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 a comfort band based on your thermostat settings to make
sure you and your family stay comfortable throughout the event. The average indoor
temperature typically increases around two degrees Fahrenheit.
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
What is Peak Time Savings doing when it is optimizing on Energy Efficiency days?
Peak Time Savings uses the weather, the unique characteristics of your home, and
your preferences to create a personalized thermostat schedule for the day that keeps
you comfortable and helps you save. This may mean that you see some different
setpoints on your Copeland Sensi.
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
