Completion of Power Generation and Heat Transport Facilities at WaiTa Geothermal Plant

Completion of Power Generation and Heat Transport Facilities

Tokyo Gas Engineering Solutions (TGES), led by President Takayuki Uenaka, has completed the construction of the power generation and heat transport facilities at the WaiTa Geothermal Plant, located in Kumamoto Prefecture. This significant project began its construction in 2024, after TGES was awarded the contract by WaiTa Geothermal Plant Co., Ltd., headed by President Kazuyuki Akaishi.

On April 15, the completion ceremony was held, marking the successful culmination of efforts to design and construct the geothermal plant's power generation and transport systems. This is the first time that TGES has undertaken the design and construction of such facilities in a geothermal power plant. The plant will be operated collaboratively by Furusato Thermal Electric Co., Ltd. and the WaiTa Association, ensuring sustainable energy production for the local community.

The WaiTa Geothermal Plant boasts a power generation capacity of 4,995 kW, with an estimated annual output of approximately 35 million kWh, which is equivalent to the electricity consumption of around 8,950 average households. The facility employs a single-flash geothermal method, which utilizes high-pressure geothermal fluids that are depressurized just once to generate steam used for electricity generation, providing a reliable and renewable energy source.

TGES aims to leverage its engineering solutions, backed by extensive experience in LNG bases, district heating and cooling, and energy services, to promote the adoption of renewable energy, significantly contributing to the broader goal of achieving carbon neutrality by 2050.

Overview of the WaiTa Geothermal Plant

- Company Name: WaiTa Geothermal Co., Ltd.
- Location: 3070-1 Yamagiwa, Nishizato, Oguni Town, Aso District, Kumamoto Prefecture
- Power Output: 4,995 kW
- Estimated Annual Generation: Approximately 35 million kWh (equivalent to around 8,950 households)
- Methodology: Single Flash Method

As part of the operations, the WaiTa Association, which consists of the heads of all 30 households in the WaiTa district, plays a crucial role in coordinating geothermal development in Oguni Town. A portion of the revenue from electricity sales is returned to the WaiTa Association, benefiting local infrastructure and supporting industrial growth within the community.

This strategic initiative not only capitalizes on the natural geothermal resources of Kumamoto but also signifies a forward-looking approach towards sustainable energy practices in Japan, laying the groundwork for future developments in the sector.
