Thailand''s renewable energy plan boosts battery
Battery energy storage systems (BESS) are essential for
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. Interestingly, this allowed generators to sign semi-firm power purchase agreements (PPAs) with the Electricity Generating Authority of Thailand (EGAT) with minimum availability guarantees.
Inside BESS are battery cells, power converter, power control and management system, and various security systems to provide the most stable energy reserve. BESS is comparable to the grid's enormous power bank that can respond to fast-changing electricity demand and immediately supply electricity when there is an increase in demand.
Therefore, BESS is one of the technologies the Electricity Generating Authority of Thailand (EGAT) uses to help enhance power system security. BESS utilizes lithium-ion battery which has several notable features, such as rapid electricity supply within milliseconds (ms), lightweight, long lifespan of over 10 years.
BESS may currently be less popular than EV batteries, but demand is expected to rise significantly in the next three to four years as households increasingly rely on renewable energy, reported Bangkok Post.
