Home My WebLink About09 Jerry Smith Storage_Commissioning_Plan ne :Amp Jerry Smith Energy Storage Commissioning Services Plan May 2026 Jerry Smith Storage, LLC 339 Jerry Smith Rd., Lansing, NY 14882 Project Description Nexamp will be installing a 5 MW / 23.5 MWh standalone Battery Energy Storage System (BESS) project (Jerry Smith Storage) at 339 Jerry Smith Rd., Lansing, NY. The system is comprised of six Tesla Megapack 2XL batteries, each rated at 979.2 kW / 3916.8 kWh. Two 2.5 MVA step-up transformers (34.5 kV/480 V) will connect the BESS to the NYSEG distribution system at the point of interconnection (POI) via customer-owned switchgear and revenue metering. The Jerry Smith site includes access road improvements, underground conduit, MV transformers, AC switchgear, a data acquisition system (DAS), perimeter fencing, and associated interconnection infrastructure. The site is designed for a 25-year operational life. At end-of-life, the system will be decommissioned with an emphasis on recycling BESS components Commissioning Process Overview Commissioning verifies that the system is installed correctly, operates safely, and meets performance and interconnection requirements. The process will include: • Installation inspections. • Equipment startups. • Functional and performance testing. • Balance-of-system (BOS) verification (transformers, switchgear, SCADA/DAS). • Utility coordination for interconnection compliance. The plan defines roles, responsibilities, commissioning documentation, inspections, and tests required to achieve final acceptance.
