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.

How much power does Thailand produce?

As of May 2019, Thailand (including imports) had installed generation capacity of 42,835 MW, of which 14,566 MW (34%) was accounted for by EGAT power plants; 14,949 MW (35%) by independent power producers; 9,443 MW (22%) by small producers; and 3,878 MW (9%) by foreign producers of imported power. Energy Policy and Planning Office. 2019.

When does electricity demand peak in Thailand?

Source: Energy Regulatory Commission. 2012. Thailand: Energy Regulation and the Promotion of Energy Conservation. Bangkok. Electricity demand in Thailand has predictable seasonal and daily cycles. Annual peak demand is generally from March to May, during periods of high temperature.

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.

Does Thailand offer private sector participation in renewable electricity generation?

The Government of Thailand has opened access for private sector participation in the renewable electricity generation business through its programs for small and very small power producers.
