ASEAN Regulatory Frameworks Urged to Evolve to Unlock Full Value of Battery Storage

Regulatory frameworks across ASEAN need to evolve more rapidly in order to fully capture the economic and system benefits of battery energy storage systems (BESS), according to industry analysis.

The report highlights that while renewable energy deployment is accelerating across Southeast Asia, policy and market structures have not always kept pace with the growing need for flexibility solutions such as energy storage. This gap may limit the ability of power systems to efficiently integrate higher shares of solar and wind generation.

Battery storage is increasingly recognized as a critical infrastructure component for modern electricity systems, enabling functions such as peak shaving, frequency regulation, renewable energy shifting, and grid stabilization. However, the value streams associated with these services are not yet fully reflected in many regional regulatory frameworks.

Southeast Asia is experiencing rapid electricity demand growth driven by industrial expansion, urbanization, and rising cooling demand. At the same time, governments are expanding renewable energy capacity to reduce reliance on fossil fuels and improve long-term energy security.

Despite this momentum, many markets in the region still lack clear revenue mechanisms for storage assets, which can create uncertainty for investors and slow project deployment. Industry stakeholders argue that clearer market design, ancillary service pricing, and capacity mechanisms will be essential to unlock large-scale investment in BESS.

The analysis also notes that as storage costs continue to decline globally, the competitiveness of battery systems is improving, but regulatory alignment will be a key factor in determining deployment speed across ASEAN markets.

Without updated frameworks, there is a risk that renewable energy growth may outpace system flexibility, potentially leading to inefficiencies such as curtailment or grid congestion.

The findings suggest that regulatory modernization will play a decisive role in shaping the next phase of ASEAN’s energy transition, particularly as storage moves from a supporting technology to a core infrastructure asset.
