The Sugar Loaf Energy Storage I project is a proposed 300 MW battery storage development in Orange County, New York. The project, being developed by CEDAR HOLDCO LLC, is located within the NYISO region and will interconnect to the Orange and Rockland (O&R) utility grid at the Sugarloaf 138 kV Substation. It entered the NYISO interconnection queue as queue ID NYISO-C24-358 on October 15, 2024, with a proposed commercial operation date of December 1, 2029.
The project consists entirely of battery storage, with a total capacity of 300 MW. The Sugar Loaf Energy Storage I project has appeared in recent news coverage regarding energy storage projects in the state.
