Building upon the success of the Wai-1 Geothermal Power Plant, which has been operational since 2015, Furusato Thermoelectric Co., Ltd. has partnered with local residents through the Wai Cooperative Association to ensure that the project benefits the entire community.

With an impressive output capacity of 4,995 kW and an estimated annual generation of around 35.36 million kWh, the Wai-2 Geothermal Power Plant promises to make a significant impact on both the local economy and the environment. Its strategic location in Oguni underscores the company's dedication to fostering sustainable development while addressing the growing demand for clean energy.

As we look towards the future, the Wai-2 Geothermal Power Plant represents not just a technological feat but also a beacon of hope for a greener, more sustainable world. With Furusato Thermoelectric Co., Ltd. leading the charge, the journey towards a brighter tomorrow has never looked more promising. Join us as we embark on this exciting adventure towards a cleaner, more sustainable future. 

This Kumamoto Geothermal power plant is an addition to Japans Geothermal power planets as we had earlier on highglighted on the one in Appi

Recently the world has been keen on Geothermal power plant however Japans Geothermal base is yet to be fully unlocked given that only 0.03 % of geothermal is being utilized even when the country is located strategicaly in the Pacific ring of a Fire , a Geothermal hotspot theres an obvious need of companies to boster up this resource With the right mode of approach.

$44.1 Million Powers NexTitan: GA Drilling Accelerates the Breakthrough That Could Finally Scale Geothermal Globally

Revolutionizing the Earth's Heat: GA Drilling Secures $44.1 Million to Accelerate NexTitan – The Breakthrough for Geothermal at Scale By:  Robert Buluma Image: Revolutionizing the Earth's Heat: GA Drilling Secures $44.1 Million to Accelerate NexTitan – The Breakthrough for Geothermal at Scale In a world urgently transitioning to net-zero emissions, geothermal energy stands out as one of the most promising yet underutilized renewable resources. Unlike solar or wind, which are intermittent, geothermal offers baseload power—steady, reliable electricity available 24/7, with minimal land use and near-zero operational emissions. The Earth's subsurface heat is virtually limitless; if harnessed effectively, it could power civilizations indefinitely. Yet geothermal's growth has been stymied by one dominant factor: the exorbitant cost of drilling deep into hard, hot rock formations. Drilling often accounts for up to 70% of total project expenses in conventional geothermal develo...
