Does Thailand need a battery energy storage system?

Thailand may lack the Battery Energy Storage Systems (BESS) necessary to navigate supply and demand challenges. The 2024 PDP draft included 10,000 MW of BESS, but this may see the country struggle to fulfil carbon neutrality and Net Zero commitments over the coming decades.

How many mw can a solar generator store in Thailand?

Their total combined storage capacity was 994 MW. Interestingly, this allowed generators to sign semi-firm power purchase agreements (PPAs) with the Electricity Generating Authority of Thailand (EGAT) with minimum availability guarantees. Many solar projects in Thailand have non-firm PPAs in place due to a lack of storage on site.

Why is battery storage a problem in Thailand?

This is partly due to a lack of clarity on how battery storage fits into existing electricity infrastructure. In 2022, the Thai government approved 24 BESS projects, all of which were located alongside solar operations. Their total combined storage capacity was 994 MW.

What is a battery energy storage system?

Battery energy storage systems (BESS) are essential for buildings and renewable power generation facilities to ensure uninterrupted electricity supply. Renewable sources like solar and wind power are intermittent, and influenced by weather patterns. BESS mitigates this issue by storing electricity for future use.

How is Thailand pursuing energy security?

Thailand is pursuing energy security not only through diversification of energy types but also by expanding its portfolio of international suppliers. In September 2024, PTT Public Company Limited signed a five-year agreement with Oman LNG to import 300,000 metric tons of LNG annually starting in 2025.

Why is Thailand transforming the energy sector?

The Thailand energy sector stands at a pivotal moment in its development, propelled by a convergence of political will, private sector innovation, and international cooperation. The country is not merely adapting to the energy transition—it is helping to define it for the ASEAN region.
