On July 14, cellcube, a European manufacturer of all vanadium flow batteries, signed a cooperation agreement with g&w electric, a U.S. - based power grid solution provider, to provide a new integrated microgrid solution to the U.S. market. G&w Electric will add the all vanadium redox flow battery (vrfb) of cellcube as a key technology to its microgrid solution and become a "value-added dealer" of cellcube energy storage system.

The partnership was launched by g&w electric to build its own state-of-the-art microgrid in Bolingbrook, Illinois, which combines solar energy with cellcube's latest battery technology. Cellcube's fourth generation vrfb will provide more reliable and resilient power during seasonal peak demand, power quality problems, and potential power outages.

G&w Electric's microgrid will cover a variety of application scenarios, including Island function, peak shaving capacity for energy conservation and sub cycle standby power supply for the protection of key assets. It will integrate rooftop solar energy to support the continuous operation of its facilities, and actively participate in comed's demand response plan by isolating itself from the grid to help reduce peak load demand. G&w Electric's microgrid will eliminate its dependence on energy at high prices and provide more reliable and flexible power during seasonal peak demand and blackouts. This 2mw/8mwh cellcube vrfb system will operate at 150% of its nominal power in order to obtain an attractive electricity price in the PJM market. The system is designed to provide an overload of up to 3MW for nearly 2 hours and work at 100% load for up to 4 hours.
