Facility Study phase initiated per LBNL queue data
The South Ripley Solar and BESS project is a proposed 270 MW hybrid solar and battery energy storage system development in Chautauqua County, New York. The project, being developed by ConnectGen Chautauqua County LLC, consists of 270 MW of solar generation. It is interconnected to the New York Independent System Operator (NYISO) queue as project number NYISO-783, with an original queue entry date of December 7, 2018.
The proposed commercial operation date for the South Ripley Solar and BESS project is January 1, 2027. Its interconnection status is currently in the Facility Study phase. The point of interconnection is the South Ripley Substation at 230kV. The project has appeared in recent news coverage.
