OAKVILLE, On. – July 7, 2025 – After a demanding testing and evaluation process, BlockEnergy announces it has received UL 9540 fire safety certification for BlockBox v4, the latest iteration of the distributed nanogrid energy storage and control system of its BlockEnergyTM microgrid platform.
BlockEnergy is the first utility-owned community microgrid for residential and commercial-scale applications. The fire safety certification is a significant milestone that allows BlockEnergy to be offered to utilities.
The BlockEnergy microgrid integrates renewable energy, storage, and smart distributed controls to facilitate easily scalable systems in new residential communities. The BlockBox energy storage and control system acts as a smart hub for the energy load it serves on the microgrid. BlockBoxes are connected on a common bus at various end-load sources, incorporating the battery management system, controls, and communications for the load, thereby serving as the integration point of various energy sources into the battery.
Microgrids will play a significant role in achieving a renewable and resilient energy future. BlockEnergy’s utility-centric model allows utilities to own and operate distributed energy resources that can be integrated with utility grid infrastructure. The BlockEnergy system provides easy interoperability in both grid-connected mode and island mode, when outages are affecting the broader grid.
The testing and evaluation was conducted by independent, third-party lab TÜV Rheinland.
