Breakthrough in Taiwan’s Deep Geothermal Energy: Academia Sinica and CPC Corporation Drill Nearly 4,000 Meters in Yilan and Find High-Potential Reservoir Published: December 10, 2025 By: Robert Buluma In a historic milestone for Taiwan’s renewable energy journey, Academia Sinica (Central Research Academy) and Taiwan’s state-owned CPC Corporation have successfully completed the island’s first-ever “deep geothermal exploratory well” in Yuanshan Township, Yilan County. The well reached a depth of nearly 4,000 meters, recorded a bottom-hole temperature close to 150 °C, and confirmed the existence of an upwelling heat source beneath the northern Yilan Plain. Researchers are now calling it a “high-potential geothermal reservoir” that could become a cornerstone of Taiwan’s green energy transition.
