PTT Group to scale battery production GPSC factory will help EV sector grow published : 20 Jul 2021 at 05:59 A battery production plant marks a significant step for GPSC to tap into the energy storage business. National oil and gas conglomerate PTT Group is aiming to scale its battery production capacity to a gigawatt-hour level after opening a factory in Rayong, the first semi-solid battery production facility in Southeast Asia. PTT runs the battery business through its power generation arm, Global Power Synergy Plc (GPSC), which on Monday held an opening ceremony online, presided over by Prime Minister Prayut Chan-o-cha. The 1.1-billion-baht factory, located in the Map Ta Phut area, currently has a capacity of 30-megawatt hours. It will produce batteries, named "G Cell", to serve electric vehicles (EVs) like tuk-tuks, buses and motorcycles used for the delivery of goods, said Worawat Pitayasiri, GPSC president and chief executive.
