By participating in Evergy’s Home Battery Storage Pilot program, you receive a FREE 16 kWh home battery storage system valued at $18,000. This battery system can help lower your energy costs and provide back-up power for essential lighting and appliances during outages. If your home qualifies, we'll install the system for free. The only cost to you is a $10 monthly program fee.
But why? This pilot program allows Evergy to test how home batteries interact with the power grid and provide back-up power for customers. In addition, it gives you further visibility and options on your energy use and costs, which helps us and you be more efficient.
What are the benefits? Aside from a free home battery storage system, there are additional benefits to this program:
- Save money: Your battery is optimized to capture energy during less expensive “off peak” rate times, and to dispense the power during more costly (peak) rate times to save you money
- Store energy you produce: If you have solar panels, the battery can even help capture extra energy to store for later use
- Keep your appliances on: If there is an outage, your battery can power critical appliances (like your refrigerator) for up to 3 hours

What to expect
The Home Battery Storage Pilot is a research and development program designed to create cutting-edge solutions to improve your energy utilization in the home... while also helping us 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 look for feedback on processes, technology and your experience to make improvements.
Some steps in the process
Evergy will process your interest form and will contact you if you’re selected for the pilot or if we need more information.
Evergy will continue to monitor the battery performance and grid interactions to gain data for future programs and offers.
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 2026. At the end of 2026, 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.
Enhancing reliability
This program is part of Evergy’s broader strategic effort to strengthen and modernize our community’s energy grid. This effort includes several targeted projects across the Evergy region to strengthen our critical energy infrastructure and build a more resilient and sustainable grid for the future.

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.
