Draft PDP targets 10 GW/10.5 GWh storage by 2037 but remains unfinalised\n* **Policy certainty now outweighs cost** as the primary barrier to APAC battery storage investment, according to Banpu NEXT — regulatory ambiguity around grid connection pathways is the biggest obstacle\n* **Data centre demand risk**: 24.2 GW of data centre capacity announced across nine APAC markets (2025-2030), which without long-duration storage could lead to 166 million tonnes CO2-equivalent/year by 2030\n\n## 中文\n\n* **亚洲储能峰会2026**将于2026年7月1-3日在泰国曼谷QSNCC举行，汇聚60多个国家超过30,000名访客和1,400个主要品牌\n* **越南引领东盟BESS监管改革**：2025年第62号通知（2026年1月生效）为BESS建立正式的两部制电价——首个超越单一电量补偿的东盟主要经济体，2026年可能释放7.5亿美元投资，到2030年达57亿美元\n* **东盟BESS部署仍然有限**，运营容量仅1.4吉瓦，尽管自2013年以来全球成本下降约90%；FESSIA/DNV报告将BESS称为东盟能源转型中缺失的一环\n* **柬埔寨构网型里程碑**：500兆瓦/1,000兆瓦时构网型逆变器系统自2026年3月起在马德望省运营，由SchneiTec基于2025年华为试验平台建设\n* **泰国落后**：天然气仍占EGAT发电量的67%，太阳能+风电仅约2%。草案电力发展计划目标到2037年实现10吉瓦/10.5吉瓦时储能，但尚未定稿\n* **政策确定性已超越成本**成为亚太电池储能投资的首要障碍，据Banpu NEXT分析——并网路径的监管模糊是最大阻力\n* **数据中心需求风险**：2025-2030年亚太九个市场公布的数据中心容量达24.2吉瓦，若无长时储能，到2030年可能导致1.66亿吨二氧化碳当量/年的排放","html_content":"
