Sineng Electric has successfully completed the grid connection of a transmission scale energy storage project in central Texas—its first utility-scale ESS installation in the United States. This milestone underscores Sineng’s commitment to accelerating the energy transition in North America and reinforces its position as a global leader in PV+ESS solutions.
The project features Sineng’s 3.2MW PCS MV Turnkey Station (EH-3200-HA-MR-US-34.5), integrating 16 units of 200kW String PCS (EH-0200-HA-M-US), a low-voltage switchboard, and a pad-mounted transformer. Its modular design enables 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. Modular design ensures system availability exceeds 99%. The system also allows 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.
Coordinated by the Headquarter Service Department, Sineng Electric worked closely with its U.S. local team to drive project delivery. Since late 2024, nearly 10 personnel were involved in both on-site and remote support, covering inspection, installation, and commissioning. Headquarter and local engineers provided rotating on-site support, joined by a third-party specialist. Through efficient cross-team collaboration, the project was successfully finished commissioning in 31 working days, ensuring high-quality system operation.
With the U.S. utility-scale storage market projected to reach 18.2GW of new capacity in 2025—a 75% year-over-year increase, according to the U.S. Energy Information Administration (EIA)—Sineng is strategically positioned to support this rapid growth. Its newly established North American service center in Texas enables end-to-end local support, ensuring timely response and delivering long-term value to partners and stakeholders.
From Texas to the world, Sineng Electric will continue driving the global clean energy transformation with advanced technology, localized service, and sustainable innovation.
