Thailand s new energy storage prices

Does Thailand have a plan for renewable-plus-storage in 2023?

In April 2023, Thailand awarded project rights for 1GW of solar capacity paired with one-to-four-hour storage. However, only 0.3GW has been commissioned to date. While the draft PDP2024 has ambitious battery capacity targets, Thailand has not clarified the mechanism to support deployment of renewable-plus-storage.

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.

Is solar the cheapest source of bulk electricity in Thailand?

Under the latest draft PDP2024, solar accounts for half of the 43 gigawatts (GW) of capacity additions planned for 2024-2037. The findings of BNEF’s economic analysis aligns with the draft PDP2024’s prioritizing of solar as utility-scale solar is already the cheapest source of bulk electricity generation in Thailand.

How will Thailand's energy policy affect the energy sector?

As Thailand plans to add significant amount of renewables capacity in the next 13 years, the government would consider more flexible gas power contract. As a result, thermal power plants will likely see their operational hours cut further. This will lead to costlier coal and gas power. Source: BloombergNEF.

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.
