## English

* **Policy certainty now outweighs cost** as the primary factor in Battery Energy Storage System (BESS) investment decisions across the Asia-Pacific region, according to Banpu NEXT's Head of Energy Generation and Trading, Colin Koon Peng Ho
* **Dynamic BESS revenue model** involving both physical dispatch and financial contracts makes stable regulatory frameworks essential for investor confidence
* **Japan leads as the benchmark market**: OCCTO selected 1,251 MW of BESS projects in its third Long-Term Decarbonisation Power Sources Auction with **20-year fixed-revenue contracts**
* **Target investment model (2028-2030)**: Utility-scale, grid-connected battery storage with selective co-located models alongside renewable energy projects
* **Southeast Asia faces regulatory barriers**: Most markets operate under **single-buyer, state-controlled models**, which creates challenges for BESS development and private investment
* **Southeast Asia outlook**: An increased pace in opening up grid access and providing suitable revenue models would be the key driver for accelerating growth between 2028 and 2030
* **Grid connection ambiguity** remains a key barrier — different regulatory treatment for front-of-meter, behind-the-meter, and co-located BESS assets creates uncertainty for developers
* **Supply chain localisation trend**: Current procurement relies on major global manufacturers, but a shift toward local procurement is expected as governments tie tenders to domestic content requirements
* **Implications for Malaysia**: As Malaysia develops its BESS framework under the Utility-Scale BESS Programme and CRESS, policy clarity will be critical to attracting investment in grid-scale storage
