Battery storage operation under net billing provides “virtually no grid value”: Berkeley Lab study
Net billing for rooftop solar, which incentivizes the use of battery storage to maximize solar self-consumption, is inefficient, researchers found, whereas incentivizing battery owners to discharge power during peak hours would provide greater value.
