PVTIME – Malaysia’s national power utility, Tenaga Nasional Berhad (TNB), has formalised a joint-development agreement with IOI Group to deliver a major utility-scale solar-battery storage facility across the nation.

The newly signed deal will see the consortium build 500MW of solar photovoltaic generation paired with 1,000MWh of battery energy storage capacity. This integrated solar-plus-storage asset is primarily designed to supply renewable electricity to corporate and industrial consumers via long-term power purchase agreements (PPAs).
By combining large-volume solar generation with sizeable battery storage, the project can mitigate the variability of solar output. Stored energy will be dispatched to meet commercial and industrial power demand when sunlight is unavailable, enabling reliable green power delivery for local businesses.
TNB will contribute its extensive national grid operational expertise to the collaboration, while IOI Group will contribute its proven experience in the large-scale deployment of land-based renewable energy projects in Malaysia. Industry observers note that this initiative marks another tangible step for Malaysia in scaling up the supply of clean, dispatchable energy, as local enterprises increase their procurement of zero-carbon power to advance their sustainability targets.
