Frequently Asked Questions

General Questions

Which products are eligible for rebates?

All of the smart thermostats, LEDs, and advanced power strips listed in the Ameren Missouri Store are eligible for rebates. The rebates are applied instantly for eligible customers and no paperwork is required. Select smart thermostats are also eligible to receive the Peak Time Savings $50 sign-up bonus instantly at the time of purchase. Eligible thermostats will be listed with this purchase option. Some non-rebated products are available for purchase which support the functionality of the rebated products.

Is there an application process for the rebates?

No, there is no application process needed for the Ameren Missouri Online Store instant rebates. The rebates are instantly applied at the point of sale.

Why do you need to verify my account?

Account verification is necessary to ensure that the rebates are available to customers with an active residential electric account from Ameren Missouri.

Is there a minimum and maximum amount I can buy?

Yes, the instantly-rebated products have limits on the amount you can purchase per account. They are as follows:

Smart Thermostats: 

1 smart thermostat per separate cooling system and up to 3 smart thermostats per residential electric account.

2 smart thermostats with Peak Time Savings Enrollment per residential electric account. Selected smart thermostats must be from the same manufacturer and be participating in the program.

LED Bulbs:

6 packs of LED bulbs per customer account, per year.

Advanced Power Strips:

5 tier 1 advanced power strips per customer account.

3 tier 2 advanced power strips per customer account.

What is the Peak Time Saving Program?

The Peak Time Savings Program is powered by Nest Rush Hour Rewards, which syncs to your Nest to understand what keeps you comfortable and how your home uses energy.

Occasionally, on those really hot days when the demand for energy is high, the program will schedule a Peak Time Savings Event. These events pre-cool your home using your comfort preferences when the demand for energy is lower. This helps you stay comfortable before, during, and after the event while conserving energy during peak times. You will be notified before every event and the program will take care of the rest.

You always have control and can adjust the temperature in your home at any time.

By participating in the program, you will save an additional $50 off today’s purchase and $25 for each additional year you participate. Increase your energy savings without ever lifting a finger!

The Ameren Missouri Online Store has free shipping and handling on orders over $25 and flat-rate shipping of $8 per order if the total is less than $25.

The billing address for your order and online store account does not need to be changed to match your credit card billing address. You do not need to request an address change as long as the shipping address is correct.

How long will it take for my order to arrive?
