As grid congestion, aging infrastructure, and renewable intermittency pose significant challenges across Asia Pacific, battery energy storage systems (BESS) are emerging as a powerful solution. Large-scale BESS are critical to decarbonizing the energy sector, while ensuring grid reliability and security. Rob Hills will discuss emerging applications for BESS, including how BESS can complement transmission investment by acting as virtual transmission that boosts capacity and improves system stability.  He will also discuss how hybrid systems (pairing renewables with storage) can boost project value, improve resilience, and navigate evolving regulations.

Across Asia, rapid growth in renewable energy capacity is outpacing grid readiness, resulting in widespread congestion and curtailment challenges. Countries like India, China, the Philippines, and Thailand have seen solar and wind curtailment rates as high as 10–15% in congested zones, while transmission constraints have stalled new clean energy deployment in key markets.

1. What regulatory models are emerging across Asia to incentivise battery energy storage systems (BESS) and grid-enhancing technologies?
2. How can demand-side management and flexible load solutions be more effectively integrated into national power planning?
3. What lessons can be drawn from Asia’s most advanced flexibility markets in addressing congestion and reducing renewable energy curtailment?
4. How can regional collaboration and cross-border energy trade enhance grid stability and unlock stranded generation assets?
5. What’s the role of transmission upgrades versus digital flexibility solutions in solving near-term grid bottlenecks?
