  • Saves $
    • Your battery will be optimized to capture energy during less expensive “off peak” rate periods and to dispense the power during more costly rate times to save you money. A Time of Use rate plan is required for pilot program.
  • Store Energy you produced
    • If you have solar panels, the battery can even help capture excess energy and store the energy for later use.
  • Keep your appliances on
    • If there is an outage, your battery can help power critical appliances like your refrigerator for up to 3 hours.

How does it work?


The battery will be programmed to charge during lower “off-peak” rate periods, and then to discharge the stored energy within milliseconds during higher “peak” rate periods, supplementing your home’s energy and creating savings for you. You can also use the stored energy during an outage as backup power.  The battery will kick on within milliseconds of an outage so that your lights and essential appliances can continue undisturbed.

What to expect

The Home Battery Storage Pilot is a research and development program designed to find you cutting-edge solutions to improve your energy utilization in the home, while helping Evergy advance the power grid. We expect the program to be a hands-on partnership that may require multiple site visits, meetings, and discussions between the homeowner and Evergy. This is truly about learning and testing, so Evergy will be looking for feedback on processes, technology and your experience so we can make improvements for future battery programs and customer experience.

Some steps in the process

After the pilot ends

Evergy selected a battery storage technology that includes a home energy management control system with cloud support. Evergy will own, install, operate and maintain the battery storage system at your home through the pilot, which ends in 2025. At the end of 2025, you will be allowed to pick from the following options: 

  • We will transfer ownership and maintenance of the battery to you under the condition that you provide Evergy with access of energy data and control the power from the battery. If needed, for the battery’s remaining useful life, you’ll be compensated if the energy from the battery supports the Evergy power grid during an emergency condition. 
  • Purchase the battery at the depreciated value with no future obligation to Evergy under this pilot; or
  • Request Evergy remove the battery.

The following information is a useful resource to customers who are interested in learning more about Evergy’s Home Battery Storage Pilot Program. 

1. What is the Evergy Home Battery Storage Pilot Program?
This program provides energy efficiency, reduces energy costs, and provides backup power during outages by using the stored energy from the battery system.

2. Why is energy storage important?
Energy storage makes it possible to balance the supply and demand of power instantaneously. This allows power grids to be more efficient and resilient. And of course, energy storage is also helpful in emergency situations, such as outages.

3. What is a battery storage system?
The battery storage system can work with home energy management controllers that provide real-time optimization of customer resources (battery, solar, and key loads) to maximize customer benefits, minimize utility grid impacts, and provide demand response for system capacity or local distribution constraints.

4. How will energy storage cut power costs?
Energy storage has the ability to cut power costs in two main ways. The primary way that participation in the Evergy Home Battery Storage Pilot Program will lead to saving is by allowing customers to avoid “on peak” or premium pricing. Additionally, battery storage will also lower the overall cost of providing electricity, which will help us manage costs for all Evergy customers.   

5. What is on peak time and how does energy storage help with peak-shaving?
On peak time is the time of day when the demand for electricity is at its highest point. During on peak times, the utility must supply expensive additional electricity production. In order to meet the high demand, there is an extra charge that must be applied by the utility to the customer. Energy battery storage will allow the customer to automatically purchase the electricity at off-peak prices for use during the peak period. This will lower your electricity production during those on peak times and allow you to avoid the extra charge.

6. How do I become a part of the pilot Program?
The pilot Program has been made available to a few select customers for testing and research in Evergy Missouri territories in hopes of deploying the program to a wider Evergy customer base within the next 1-2 years. Email renewables@evergy.com to request an application.
