Viridi and Good Carbon deploy 3.75 MWh indoor battery at Buffalo affordable housing building

Viridi and Good Carbon Co. announced October 20 that they deployed a 3.75 megawatt-hour lithium-ion battery system at Peace Bridge Place, a 105-unit affordable housing building in Buffalo, New York. The companies describe it as one of the largest indoor systems of its kind in an occupied U.S. residential building. That size ranking is their characterization, not an independently audited national comparison.

The RPSLinkIN system is spread across seven battery rooms. It is part of a broader electrification plan that includes geothermal heating and cooling, domestic hot water and building-envelope upgrades. The battery is designed to provide backup electricity during outages and reduce grid demand during peak periods. The announcement does not establish a measured outage-runtime guarantee or a dollar saving for each household.

The energy-management system can discharge the battery as building demand approaches a monthly peak, aiming to reduce demand charges. For seasonal demand-response events, National Grid signals pass through EnergyHub's platform to Viridi's system, which coordinates the battery and other building equipment. Participating residents' thermostats can pre-heat or pre-cool apartments before an event, and residents can opt out of individual events.

The announcement says the project receives NYSERDA Future Grid Challenge support and is a National Grid pilot. Viridi says its passive anti-propagation architecture is designed to stop a failing cell from triggering neighboring cells. The company reports no cell-to-cell propagation in UL 9540A testing and UL 9540 listing of the complete system by TUV Rheinland. Those are attributed testing and certification claims, not a promise that a battery can never fail.
