Battery Rewards FAQs

1. Does it cost money to join the HBR Program?

No. The exact opposite. The number of Powerwalls you have and how soon you enroll determines the number of Rewards you earn.

2. How much will I earn by participating?

The amount you’re paid to participate depends on your system size, KWH produced, and time of use depending on grid demand. You will get an estimated range of savings when you enroll and you will see your fixed monthly payment on your utility bill after you enroll.

3. Is there any time commitment?

No. You are free to un-enroll at any time.

4. How do I receive my rewards?

You will see a reduction on your electric bill every month. The HBR program will have a special itemized line on your bill. If your incentive reaches your minimum bill or goes beyond your minimum bill you’ll also get a check from Hawaiian Electric each month.

5. How do I sign up?

Simply enroll by filling out the contact form at the top of this webpage. An Energy Consultant will get in touch to provide you with further details and answer any questions you have regarding the program.

6. What if I only pay the minimum fee on my electric bill?

Your bill will be reduced by the incentive amount, including all KWH charges and the monthly service charges. If your incentive exceeds your minimum bill, you will receive a bill for $0, and a check from Hawaiian Electric enclosed with your monthly bill for the remaining value of the incentive net of bill credits.

7.How will my battery be managed for the HBR Program?

Your battery will be intelligently managed for the duration of the program to maximize the value of your normal operations and HBR benefits each day.

8. What happens during a grid outage? Will my battery be asked to provide electricity to the grid?

Your system will “Island” itself and only provide electricity to your home as originally designed.

9. What are the program requirements?

You must have a Solar + Tesla Powerwall System and be a Hawaiian Electric customer on Oahu, Maui, or the Big Island. You must unenroll from other Hawaiian Electric energy efficiency programs (i.e. HECO’s “Energy Scout” Program) to benefit from the Hawaii Solar Battery Rebate.

10. How does the Program Work?

Swell Energy Hawaii manages your system and all participants in the Home Battery Rewards Program to respond to too much or not enough power on the grid. The program’s value is based on the fact that your system can intelligently respond in real-time to the energy needs of the grid.

11. I have solar plus battery storage, but not a Tesla Powerwall. Do I need a Tesla Powerwall to enroll?

At this time, only Tesla Powerwall customers in Hawaii can enroll in the Home Battery Rewards rebate Program. Let us know your battery type by filling out the contact form and we will be in touch to discuss how you can participate when we are ready to enroll your battery type.
