Sineng Electric has completed the grid connection of a transmission scale energy storage project in central Texas, its first utility-scale ESS installation in the United States, the milestone underscoring the company’s commitment to accelerating the energy transition in North America and reinforcing its position as a global leader in PV+ESS solutions.
The project features Sineng’s 3.2MW PCS MV turnkey station, integrating 16 units of 200kW string PCS, a low-voltage switchboard and a pad-mounted transformer, its modular design enabling rack-level battery management, boosting battery utilization by over 7%. With one-to-one pairing between PCS and battery clusters, each cluster operates independently, reducing downtime, enhancing energy control and optimizing charge/discharge performance. This setup also improves SOC balance and minimizes the long-term impact of battery inconsistencies. Short-circuit current is limited to 10kA for safer operation, with the modular design ensuring system availability exceeding 99% and also allowing for seamless integration of additional battery clusters for future expansion. Now in operation, the facility will provide essential grid services including frequency regulation, peak shaving and reserve capacity, contributing to grid flexibility and stability in one of the most dynamic power markets in the U.S.
With Sineng headquarters working closely with its local team in the U.S., the project was commissioned in just 31 working days.
With the U.S. utility-scale storage market projected to reach 18.2GW of new capacity in 2025, Sineng is strategically positioned to support this growth, its newly established North American service centre in Texas enabling end-to-end local support, ensuring timely response and delivering long-term value to partners and stakeholders.
