Kehua Digital Energy's BCS1250K-C-HUD series PCS (Power Conversion System) has been deployed in a 50MW/100MWh energy storage project in Hanoi, Vietnam. This project marks the first large-scale energy storage application in the capital's power grid. The project consists of five 10MW/20MWh energy storage systems, with the last system successfully connected to the grid on July 5th, signifying full operational completion.
The project is owned by EVN Hanoi, with VinEnergo providing the battery systems and ACIT handling integration. The five systems are deployed at five 110kV substations in Hanoi, charging during off-peak hours and discharging during peak hours to provide frequency regulation and load management services. This project also serves as a pilot project for EVN Hanoi, evaluating the performance of energy storage under real-world operating conditions.
This is Vietnam's first large-scale grid-side energy storage project. Southeast Asia is emerging as a new market for grid-side energy storage. For Chinese PCS and system integrators, this market involves the export of localized integration, substation engineering delivery, and long-term operation and maintenance capabilities, rather than just equipment exports.
