Puerto Rico dispatched Sunrun home batteries for 18 consecutive days to provide grid services, demonstrating the practical value of distributed storage as virtual power plant (VPP) capacity for peak shaving, frequency support, and backup power. The sustained dispatch period shows that residential storage can be called upon as a recurring grid resource rather than an emergency-only asset.
This means storage batteries are shifting from backup devices to dispatchable assets, raising grid-side requirements for cycle life, communication protocols, aggregation scheduling, and safety standards. This means battery and BMS suppliers should focus on interoperability with grid dispatch platforms, long-term degradation data, and multi-scenario safety certification, because aggregators will favor hardware that can be monitored and controlled remotely at scale. Supply chain opportunities center on standardized storage modules and aggregation control solutions.
| Requirement | Supplier Implication |
|---|---|
| Cycle life | Repeated dispatch accelerates degradation; documented cycle data supports warranty and planning. |
| Communication protocols | Interoperability with aggregator and grid platforms is essential for dispatchability. |
| Aggregation scheduling | BMS telemetry must support remote monitoring and coordinated control. |
| Safety standards | Multi-scenario certification supports deployment across residential and grid-adjacent use cases. |

VPP dispatch duty cycles accelerate degradation; storage packs need documented cycle-life data, robust BMS telemetry, and standardized communication for aggregator integration.
