                                2.5 MW/5 MWh Installation in Vietnam with StellaON 1250K

                                A 2.5 MW/5 MWh installation deployed in partnership with Great Power and local EPC partner XCE Energy for Vietnam Electricity Group (EVN) in Vietnam.


                                The project deploys two SINEXCEL StellaON 1250K power conversion units and a 5 MWh Great Power battery container, feeding into a 22 kV substation through an integrated step-up transformer cabin to deliver peak shaving, frequency regulation, and energy arbitrage services. Designed as a validation platform, the project enables EVN to assess diverse energy storage use cases across its national grid infrastructure.
