S2. Enphase grid services Adding value to customers and communities with Enphase solar and battery systems. In 2023, we expanded our grid services programs, enabling more homeowners with IQBatteries to participate in utility programs and earn money. These programs, also known as virtual power plants (VPPs), create a network of home batteries that utilities and grid operators manage. Homeowners who enroll in a VPP send the stored energy in their home batteries to the grid to help electric utilities avoid using power from expensive, polluting power plants when power demand is higher. In return, homeowners can receive hundreds to thousands of dollars toward their home battery system purchase or as annual incentive payments. In many grid services programs, customers can sign up, monitor, and control participation in the program using the Enphase App or via their energy providers’ web portal or apps. The incentives reduce the cost of the home energy system and help make home batteries more accessible and a昀昀ordable for more people. Homeowners enrolled in these programs can still use their reserved energy for backup power when the grid is down, and Enphase Storm Guard can prioritize a full charge for the battery when triggered. An overview of our grid services programs can be found on our website. Enroll Monitor Backup and opt-out ENVIRONMENTAL, SOCIAL, AND GOVERNANCE REPORT 2023 63
