Adaptive Recloser Solution for Indonesia's Volcanic Geothermal Plants: Enhancing Grid Resilience in Extreme Environments
Project BackgroundIndonesia possesses approximately 40% of the world's geothermal resources, with a geothermal power generation potential of 23–28 GW. However, by 2022, only about 2.3 GW had been developed. The government aims to achieve 5,000 MW of installed capacity by 2025 but faces multiple challenges:​Grid Stability Issues: Geothermal plants are predominantly located in remote volcanic zones (e.g., Sumatra, Java), where frequent geological activity causes earthquake- and landslide-ind

Vietnam Flood-Resilient Recloser Solution: Solving Immersion Protection in Monsoon Zones
Project BackgroundVietnam's tropical monsoon climate causes annual floods lasting 4-5 months, severely damaging power infrastructure. The 2020 central Vietnam floods paralyzed grids, delaying rescue operations. Traditional circuit breakers fail under water immersion, and manual restoration is inefficient. Although flood control infrastructure has improved, rapid power recovery remains a critical gap. ​Recloser​ devices, if unprotected, are highly vulnerable to flood-induced short circuits. Enhan
