  • 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

  • 日本树立标杆市场：OCCTO在第三次长期脱碳电源拍卖中选定1,251兆瓦BESS项目，提供20年固定收入合约
  • 目标投资模式（2028-2030年）：公用事业级并网电池储能，以及与可再生能源项目选择性共址部署
  • 东南亚面临监管障碍：大多数市场采用单一买方、国家控制模式，对BESS开发和私人投资构成挑战
  • 东南亚展望：加快开放电网接入并提供合适的收入模式，将是2028至2030年间加速增长的关键驱动力
  • 电网接入模糊性仍是关键障碍——表前、表后和共址BESS资产的不同监管处理方式给开发商带来不确定性
  • 供应链本地化趋势：目前采购依赖全球主要制造商，但随着政府将投标与国内含量要求挂钩，预计将向本地采购转变
  • 对马来西亚的影响：随着马来西亚在公用事业级BESS计划和CRESS下发展储能框架，政策透明度对吸引电网级储能投资至关重要
