## English

* **Pacifico Energy's Head of Energy Storage, Mahdi Behrengrad**, warns Southeast Asian BESS developers to engage with regulators, utilities, and communities early — before restrictive policies emerge
* **Japan's cautionary tale**: Regulators 'got caught off guard' by the surge in BESS interest and responded with increasingly restrictive measures over the past 3-4 years
* **Japan's LTDA auction now limits bids to only 6-hour duration systems** in its most recent round — a significant constraint that didn't exist initially
* **Revenue clawback**: Developers must give back 90% of merchant earnings under Japan's LTDA revenue model — severely limiting profitability
* **Many projects described as 'speculative and opportunistic'** — a warning against rushing into markets without understanding regulatory trajectories
* **Utilities imposing 'far more and more tiny clauses'** with higher costs, longer grid work timelines, and increasingly severe technical requirements
* **Grid connections have 'far less value'** as both charging and discharging are non-firm — reducing the economic case for grid-connected BESS
* **Growing cybersecurity and protectionism concerns** making the business environment 'denser and more difficult' across the region
* **Communities becoming 'skittish'** due to perceived 'land grab' by BESS and data centre developers — early community engagement is essential
* **Malaysia's BESS market opportunity**: With TNB's RP4 tariff hikes driving industrial demand for storage, Malaysian developers who engage stakeholders proactively can avoid the pitfalls Japan experienced
* **Context**: Precedes Energy Storage Summit Asia 2026 (July 1-3, Bangkok) — a key industry gathering for ASEAN storage market
