Logical Buildings, in collaboration with AvalonBay Communities, Inc., has installed the first indoor lithium-ion battery storage unit in New York State at Avalon White Plains, a 407-unit luxury rental property at 27 Barker Avenue in White Plains, NY. The circa 2008 master-metered building is now benefiting from a demand-response initiative in which a 144kW battery bank discharges at peak hours to support the electricity grid when under stress; and re-charges at off-peak times to take advantage of low cost, low carbon emission power. Another advantage is the battery is able to serve as a generator in the event of power outages. The indoor installation of the lithium-ion battery, which is comparable in size to two side-by-side refrigerators, required new safety guidelines commensurate with the revolutionary technology. Building codes were updated and an intensive review process initiated by the City of White Plains included industry peers and utility provider Con Edison. With unwavering support from NYSERDA, Logical Buildings was able to navigate funding and permits from the various entities. Moreover, through the leadership demonstrated by AvalonBay and Logical Buildings, it is anticipated similar indoor battery installations will be implemented in other high-density areas throughout the state, including New York City. On July 27, the battery participated in a two-hour demand-response event called by local utility, Con Edison. The building provided ~100kW from discharging the battery and another ~50kW by reducing demand from other systems, such as cooling and lighting. This is an example of one way the battery contributes to grid stability when demand is highest. AvalonBay purchased both the Stem battery and its proprietary Athena AI software analytics systems to reduce daily peak demand through charging and discharging. Logical Buildings worked with Stem to integrate the demand-response signals being received by its SmartKit AI™ software into battery demand-response algorithms that automatically optimize battery discharge during four-hour load reduction windows. Immediately after going live in June during the first heatwave of the summer, the lithium-ion battery was able to offer 50kW of demand reduction at the building for two consecutive days. It is anticipated the battery will deploy at least four times per month over the summer.
