Buffalo affordable housing complex installs 3.75 MWh battery for backup power and grid relief

A 3.75 MWh lithium-ion battery system is now operating at Peace Bridge Place, an affordable housing complex in Buffalo, New York. The battery is designed to charge when power is plentiful and cheap, then run the building when grid demand is high or during outages. Viridi and Good Carbon Co. installed the system with support from NYSERDA, and National Grid can call on it to reduce demand on the local grid. The project is part of a broader push to show that larger batteries can be installed safely inside residential buildings. Viridi says it spent six years testing a fireproof enclosure that isolates failed cells, and the system has a UL 9540 listing for indoor use without extra fire suppression. The building is all-electric and uses geothermal heating and cooling, so the battery adds resilience without relying on natural gas.

Nice to see storage moving into residential buildings. 3.75 MWh is not huge, but if it runs a whole affordable complex for days, that's a real use case. The safety testing is the part worth watching, since indoor batteries have been a hard sell after the fire headlines.

Would be good to know the charge/discharge power rating, not just energy. MWh tells us capacity, but MW tells us how much load it can carry and how it participates in peak shaving. Also curious what demand response contract with National Grid actually pays.

Worth noting NYSERDA funded this as part of disadvantaged community clean energy work. That matters because storage economics in affordable housing are not automatic. The utility payment for not drawing from grid is a tariff design choice, not something every market will provide.

The all-electric geothermal building angle is the part I like. Battery plus heat pumps plus no gas line is the kind of package that makes electrification work. Question is maintenance and replacement cost over 10 or 15 years, especially for a housing operator.

Anyone know how the carbon accounting works here? The battery charges from grid mix, so the emissions benefit depends on when it charges and discharges. If it charges from hydro overnight and displaces peakers in the evening, that's meaningful. Article does not say.
