An off-site corporate PPA with Kyuden Mirai sets the framework for geothermal power supply to the buildings of Tokyo Tatemono in Tokyo, Japan.
An off-site corporate power purchase agreement (PPA) has been signed between real estate Tokyo Tatemono Co. Ltd., Nippon Steel Engineering, and geothermal developer and operator Kyuden Mirai Energy Co. Ltd.
Under the PPA, three office buildings owned and managed by Tokyo Tatemono in Tokyo, Japan will be supplied with geothermal power from Kyuden Mirai’s geothermal power plants. This will be supplied via retail electricity supplier Nippon Steel Engineering.
Through this initiative, it is expected that approximately 900MWh of electricity will be received annually, which will result in an annual CO2 reduction of approximately 360 tons. In addition to geothermal power (which is the base electricity source), solar power generation provides additional electricity during the daytime.
The three buildings involved in this PPA are the following:
Tokyo Tatemono Yaesu Building (Chuo Ward, Tokyo)
Tokyo Tatemono Yaesu Sakuradori Building (same location as above)
Osaki Center Building (Shinagawa Ward, Tokyo)
Geothermal power will be supplied from the four geothermal power plants operated by Kyuden Mirai – – the Hatchobaru Power Station (110 MW), Takigami Power Station (27.5 MW), Yamakawa Power Station (30 MW), and Ogiri Power Station (30 MW). Work is underway for another 5-MW geothermal power plant in Kirishima.
At the end of 2024, Kyuden Mirai announced a wholesale auction for up to 600 million kWh of electricity generated from their geothermal power plant. The geothermal operator had also previously entered another geothermal PPA with electronics manufacturer Panasonic for their facilities in Japan.
