Sungrow and ERS Energy reach 1 GWh storage milestone across Malaysia and Philippines

Sungrow and ERS Energy reached a combined 1 GWh energy storage project milestone across Malaysia and the Philippines. The milestone was marked during a signing ceremony.

In Malaysia, the companies are working on the 441 MWh MyBeST project in Bahau. The four-hour battery energy storage system is being built with ERS Energy as the EPC contractor. It forms part of Malaysia's national large-scale battery energy storage initiative led by the Energy Commission of Malaysia.

The MyBeST project is expected to support grid flexibility by storing electricity during periods of high supply and dispatching it when required. It is also expected to facilitate greater integration of variable renewable generation, including solar power, while supporting the overall reliability of Malaysia's power system.

In the Philippines, Sungrow and ERS Energy are collaborating on a 556 MWh BESS project for ACEN. That project also has a four-hour duration, with ERS Energy serving as the EPC contractor.

The Philippine system incorporates grid-forming capabilities that enable the battery to provide support for grid voltage and frequency. It is expected to participate in the Wholesale Electricity Spot Market, allowing stored electricity to be dispatched based on prevailing market conditions.

Sungrow said it will continue working with partners across Southeast Asia to deploy energy storage solutions aimed at strengthening grids, increasing renewable energy integration, and supporting the development of more resilient power systems.
