Enroll Now
Get rewarded for your battery storage system.
EnergyWise® Home is a simple way to help your community by letting Duke Energy Progress more effectively manage energy on the electric grid. By enrolling your qualifying battery storage system in this program, you agree to let us adjust your battery control operating settings and utilize electricity stored on your battery between 30-36 times per year.
You’ll still maintain stored energy for your use at home. Plus you will receive a monthly bill credit.
How it Works
A signal will be sent to enrolled batteries at a specific time to temporarily adjust the system’s operating settings (charge, discharge, hold state of charge, return to normal operations, change of mode and store energy) and provide stored electricity back to the grid. You in turn get monthly bill credits for participating.

1For larger battery systems (more than 3 batteries), contact Duke Energy to confirm nameplate capacity continuous discharge rate (kW) and monthly bill credit amount.
2Eligible battery system makes and models may be purchased from other companies besides the listed battery manufacturers.
3kWh reflected is usable energy per product specifications.
4Battery system makes/models may be removed or added from time to time as determined appropriate by Duke Energy (i.e., issues with data collection and testing connectivity with the control vendor and/or manufacturer). Customer battery system eligibility is based on the makes/models eligible at the time of customer enrollment.

Frequently Asked Questions
Duke Energy Progress will confirm your eligibility. You will be notified once your enrollment is accepted, including a test for connectivity. You will receive monthly bill credits for continuing to meet program requirements, including internet connectivity and participating in events.
The EnergyWise Home program allows Duke Energy Progress to use flexible resources, such as your battery, to support the operation of the grid. We will call an event, which lets your device know we are asking to use it at a specific time. This decreases the use of less efficient and more expensive energy sources to support the grid.
Events last no more than 48 hours and may consist of some or all of the following: battery charging, battery discharging to the grid, change of battery mode(s), hold of battery state of charge.
Participants in the battery control option will receive a monthly bill credit based on the make and model of their battery storage system enrolled in the program. Bills will be calculated based on the consumption and discharge of the home’s meter and the customer’s rider and rate schedule selection. Your rate can be found at the top of your electric bill. More information on rate types is located at duke-energy.com/rates.
A monthly bill credit for qualifying customers is calculated based on the total nameplate capacity continuous discharge rate (kW) for eligible batteries enrolled and approved in the program. The total nameplate capacity continuous discharge rate (kW) is multiplied by $6.50 (value is per kW) and is then adjusted by a capability factor, which at this time is 70.9%. The capability factor accounts for various program-wide operational and program constraints, including, but not limited to, reliability of device connection, system losses, and system charge at the time of an event. The monthly bill credit does not change each month and can be found listed in the eligible battery make and model table above.
Duke Energy Progress will send a message through the battery control provider to your battery during an event with information on the specific event start, duration and electricity demand. This will then cause your battery to charge, if necessary, prior to the event to maximize your battery’s availability for discharge back to the grid.
The event period can last up to 48 hours. The charge and discharge length will be dependent on your specific battery system. Event charge and discharge will typically range from one to three hours.
Participants will have the option to opt out of up to four control events per year and remain enrolled in the program. If a participant chooses to opt out of more than four events per year, they may be removed from the program. An opt-out includes non-participation from part or all the event time period and includes those instances where Duke Energy Progress is unable to communicate with the customer’s installed equipment during an event.
Customers will begin receiving bill credits for participation in the program on the next bill cycle following enrollment. The enrollment process may require 30 days for completion, and at this time is likely to include a test for connectivity to the battery. Bill credits are monthly whether an event occurs or not.
Currently, only residential customers with Duke Energy Progress electric service in North Carolina are eligible to participate in the program.
You can contact us at EWHBattery@duke-energy.com to be removed from the program. If you decide to withdraw from the program, the monthly bill credit(s) from participation in this program will no longer appear on your bill.
No, there is no cap on the number of batteries you can enroll, however the incentive you qualify for will be limited by the residential Interconnection limit of 20kW.
Yes, if you have multiple batteries that qualify, the total nameplate capacity continuous discharge rate (kW) for all qualifying batteries will be used to calculate your monthly bill credits. Note that the residential Interconnection limit of 20kW applies to all incentive calculations such that, for example, if you are installing two 15kW (eligible) battery systems, your incentive would not reflect 30kW, but would be capped at 20kW per Interconnection limits.
