Kuala Lumpur, July 30, 2026 – In a move that underscores Malaysia’s accelerating energy transition, OCBC Bank has committed RM325 million in financing to ERS Energy’s flagship battery energy storage project.
The deal, announced this week, positions Malaysia at the forefront of Southeast Asia’s clean energy ambitions and highlights the growing role of financial institutions in shaping the region’s decarbonization agenda.
The project, spearheaded by ESS Bahau Sdn Bhd, a subsidiary of ERS Energy, will deliver a 100MW/400MWh Battery Energy Storage System (BESS) under Malaysia’s Battery Energy Storage (MyBeST) program.
Scheduled to begin commercial operations in July 2027, the facility is designed to stabilize the national grid, absorb excess renewable power, and release it during peak demand.

OCBC is serving as the Mandated Lead Arranger and Facility Agent, providing not only long term financing but also working capital facilities to support engineering, procurement, construction, and commissioning.
“This financing reflects our commitment to advancing critical energy infrastructure and accelerating Malaysia’s shift to a lower-carbon economy,” said Jeffery Teoh Nee Teik, Head of Wholesale Banking at OCBC.
The significance of the project extends beyond its technical specifications.
Malaysia’s National Energy Transition Roadmap (NETR) sets an ambitious target of achieving 70 percent renewable energy capacity by 2050.
Large scale battery storage is seen as indispensable to that vision, enabling solar and wind power to play a larger role without compromising grid reliability.
ERS Energy, already a prominent player in solar development, is now positioning itself as a pioneer in utility scale storage.
By winning a competitive bid under the MyBeST program, the company has secured a place in Malaysia’s evolving energy ecosystem.
Analysts note that the structured nature of MyBeST emphasizing transparency and efficiency could serve as a model for other Southeast Asian nations exploring storage solutions.
The financing also sends a strong signal to investors. At RM325 million, the deal represents one of the largest commitments to a single renewable infrastructure project in Malaysia.
It underscores confidence in the country’s regulatory framework and its ability to attract capital for complex, long-term projects.
Still, challenges loom. Execution risk remains high, with the project’s success hinging on timely delivery by 2027.
Global supply chain constraints for battery components could drive up costs or delay commissioning.
Moreover, sustained government support under NETR and MyBeST will be critical to ensuring the project’s viability.
Regionally, Malaysia’s leadership in battery storage could set a precedent.
Neighboring countries such as Indonesia and Vietnam are exploring similar technologies, but Malaysia’s roadmap and financing mechanisms give it a competitive edge.
If successful, the Bahau project could catalyze further investments, reinforcing Malaysia’s ambition to become a renewable energy hub in Southeast Asia.
For OCBC, the financing is more than a balance sheet entry.
It is a strategic bet on the future of energy in Malaysia one where batteries, not fossil fuels, will keep the lights on.
