Peak Time Savings Event

Updates sent to your smart phone from Peak Time Savings make it easy to participate

Peak Time Savings Events or "energy rush hours" will be implemented on days in the summer that create a heavier demand for energy. To ensure everyone's energy needs are met efficiently, we are offering Peak Time Savings Events to reduce demand where we can. These events will pre-cool your home using your comfort settings when energy demand is lowest and limit your air conditioning usage during the event. This helps you stay comfortable before, during and after the event while also conserving energy during peak times. You'll always be notified when an event is scheduled.

Seasonal Savings

Some Peak Time Savings program participants may be invited to participate in Seasonal Savings as a part of the program offering. Seasonal Savings can give your Google Nest thermostat's temperature schedule a tune-up in the early summer and winter. By automatically making small changes, Seasonal Savings helps you use energy more efficiently. Seasonal Savings uses the temperature preferences your Google Nest thermostat learns to find ways to save energy without compromising comfort.

Here's How it Works:

  • Make sure that your home's cooling system is operated by a qualifying Wi-Fi 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 your enrollment in the Peak Time Savings Program, powered by Nest Rush Hour Rewards, online. You may also call 1.877.215.5752 for additional questions.
  • You will receive a confirmation email from the Peak Time Savings Program that you are officially enrolled. You'll receive $50 as a sign-up bonus if you did not receive the $50 sign-up bonus as an instant incentive when you purchased your qualifying thermostat at the Ameren Missouri Online Store.
  • On certain dates that energy demand is exceedingly high - and only Monday through Friday during the months of May through September - your smart thermostat will automatically adjust to circulate the cooled air in your home. These times are called 'events' or 'energy rush hours' 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.

What is a Peak Time Savings Event, also called an "energy rush hour"?
On certain days during the summer, the Peak Time Savings Program will run an event to save energy during high demand times. During these events, the Peak Time Savings Program, powered by Nest Rush Hour Rewards, will manage your cooling schedule to reduce the runtime of your HVAC system when there is the most demand for energy. To ensure your comfort, we cool your home in advance of a Peak Time Savings Event when energy demand is low.

If at any time your home feels too hot, simply adjust your thermostat.

Frequently Asked Questions - Seasonal Savings Questions

What is the Seasonal Savings offering?
Seasonal Savings gives your Google Nest thermostat's temperature schedule a tune-up in the early winter and summer. By automatically making small changes, Seasonal Savings helps you use energy more efficiently. Over time, your Google Nest thermostat learns your temperature preferences, and Seasonal Savings uses this information to help you save more energy without compromising your comfort.

When Seasonal Savings is adjusting temperatures, the changes it makes are subtle, just a fraction of a degree each day. Over the course of the entire tune-up period, the changes typically add up to about 1℉. The biggest temperature adjustments usually happen while you're asleep or away, so you may never even notice the changes made by Seasonal Savings.

Not all customers will be invited to participate in Seasonal Savings. In order to properly evaluate the effectiveness of the Peak Time Savings Program, we must reserve a group of customers (called a control group) to provide a comparison to other customers who are participating.

Can I adjust my thermostat during Seasonal Savings?
Like any good assistant, Seasonal Savings keeps you in control. If you don't like a temperature that it has set for you, you can simply change it - your Google Nest thermostat will learn the new temperature as well as your comfort preferences.
Will all customers be offered to participate in Seasonal Savings?
Not all customers will be invited to participate in Seasonal Savings. In order to properly evaluate the effectiveness of the Peak Time Savings Program, we must reserve a group of customers (called a control group) to provide a comparison to other customers who are participating.
