Earn Cash
You’ll earn rewards for allowing your EP Cube battery system to discharge energy when the grid needs it. Incentives vary based on performance and depend on your state and utility provider.
Earn Money by Supporting the Grid
Through this Program, customers of National Grid, Eversource, Rhode Island Energy and Cape Light Compact with EP Cube systems can choose to send their extra, stored power to the grid to help reduce demand and lower the amount of pollution generated during peak hours.

Participants earn money based on their level of participation in each demand response event.
