Sungrow Energy Storage Southeast Asia: 1 GWh Rollout
September 15, 2026 — Sungrow Energy Storage Southeast Asia and ERS Energy have signed an agreement to install 1 GWh of battery energy storage systems in Malaysia and the Philippines.
Milestone: 1 GWh Battery Rollout in Malaysia and the Philippines
The deal covers two flagship projects – a 441 MWh MyBeST battery system for Malaysia’s grid and a 556 MWh ACEN‑backed storage plant in the Philippines – both aimed at bolstering renewable integration and reducing reliance on fossil‑fuel peaking plants.
Sungrow Energy Storage Southeast Asia: Malaysian MyBeST Project Boosts Grid Stability
The MyBeST installation is a four‑hour, 441 MWh battery‑energy‑storage system (BESS) that will sit alongside solar farms in Peninsular Malaysia. By delivering fast‑response power, it smooths solar output fluctuations and cuts the need for diesel‑generated peaking capacity, directly supporting Southeast Asia’s renewable energy grid stability.
Philippine ACEN project Enables Market‑responsive Power
In the Philippines, the 556 MWh, four‑hour grid‑forming BESS will be linked to the ACEN renewable portfolio. Grid‑forming technology allows the battery to set voltage and frequency, letting it participate in the Wholesale Electricity Spot Market (WESM) and provide ancillary services such as frequency regulation.
Industry perspective
“The question for Southeast Asia is no longer whether we can generate more renewable energy, but whether our power systems are ready to support it,” said Michael Ruan, Southeast Asia Director of Sungrow. “That is where energy storage makes the difference. Together with ERS Energy, we are helping build the flexibility and resilience needed to unlock more renewable energy and deliver reliable power for communities and businesses across the region.”

Regional Renewable‑Energy Context
Southeast Asia has pledged to add over 200 GW of renewable capacity by 2030, but many grids still lack the flexibility to absorb intermittent power. National plans in Malaysia and the Philippines now call for multi‑gigawatt‑hour battery capacity, making large‑scale projects like MyBeST and ACEN essential for grid reliability.
Key Figures and Timeline
- Total storage commitment: 1 GWh
- Malaysia MyBeST: 441 MWh, 4‑hour BESS
- Philippines ACEN: 556 MWh, 4‑hour grid‑forming BESS
- EPC partner: ERS Energy
- Signing date: 14 Sept 2026
- Expected commissioning: Q4 2027 (Malaysia) and Q2 2028 (Philippines)
What’s Next
Sungrow plans to evaluate additional sites in Thailand and Vietnam, while ERS Energy will continue as the EPC lead for future battery projects. The company’s broader Southeast‑Asia strategy targets another 2 GWh of storage contracts by 2030, reinforcing Sungrow energy storage Southeast Asia’s market presence.
FAQs
What is the total capacity of the new battery projects?
The two projects together provide 1 GWh of storage – 441 MWh in Malaysia and 556 MWh in the Philippines.
When will the MyBeST and ACEN storage systems be operational?
The Malaysian MyBeST BESS is slated for commercial operation in Q4 2027, while the Philippine ACEN system is expected to start in Q2 2028.
How does grid‑forming battery storage work?
Grid‑forming BESS can create and maintain voltage and frequency on its own, acting like a virtual power plant and delivering ancillary services without relying on an external grid reference.
