The Harlem River Yard project is a proposed 79.9 MW battery storage project located in Queens County, New York. Developed by Harlem River ESS, LLC, the project consists of 79.9 MW of battery capacity. It is currently active in the New York Independent System Operator (NYISO) interconnection queue as queue ID NYISO-907, with an entry date of September 4, 2019. The proposed commercial operation date is January 1, 2028. The project's interconnection status is currently in the System Impact Study phase, and it is slated to connect to the Hell Gate 138kV point of interconnection.
The Harlem River Yard project has been mentioned in recent news coverage related to grid infrastructure.
