BlockEnergy is the first utility-owned community microgrid for residential and commercial applications. The fire safety certification is an important milestone that enables 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, equipped with EnerDel’s lithium-ion batteries, acts as a smart hub for the energy load it serves on the microgrid. BlockBoxes are connected to a common bus at different end load sources, incorporating the battery management system, load controls and communications, thereby serving as the integration point of different energy sources in the battery.

“Less than two years ago, we completed our proof of concept for the BlockEnergy microgrid and distributed BlockBox nanogrids on Kirtland Air Force Base in New Mexico. Achieving UL 9540 certification is a critical safety milestone in our engineering and development work,” said Rob Bennett, president and CEO of Emera Technologies. “We are looking forward to deploying our first commercial and residential BlockEnergy microgrid installations in Tampa, Florida, and Fairmount Heights, Maryland, early 2022.”

BlockEnergy’s utility-centric model enables 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-tied mode and island mode, when outages affect the wider grid.

“Partnering with Emera Technologies on the BlockBox distributed battery system is an incredible achievement for both teams,” said Bruce Silk, senior director of business development at EnerDel. “The EnerDel team is impressed with Emera’s focus on safety, which aligns perfectly with our culture of safety and performance. This strategic alliance is evidence of a new opportunity as we expand our market and product portfolio.”

The tests and evaluations were carried out by the independent, external laboratory TÜV Rheinland.
