Electronics manufacturer Panasonic has entered into a geothermal power purchase agreement with Kyuden Mirai Energy for its factories in Japan.
Global electronics manufacturer Panasonic has entered into a geothermal power purchase agreement with geothermal developer and operator Kyuden Mirai Energy, a subsidiary of Kyushu Electric Power. The PPA is for approximately 50 GWh of electricity per year, which will reduce CO2 emissions by about 22,000 tons.
Assuming a capacity factor of 90%, the power output under the PPA is equivalent to about 6.3 MWe of installed capacity. The PPA is effective starting 1 April 2025. This is the first geothermal PPA that Panasonic has signed and will go towards achieving zero-CO2 status for their factories in Japan.
Panasonic has been active in its decarbonization efforts since 2022 with its mission of “Realizing a society in which the pursuit of happiness and a sustainable environment are in harmony without contradiction.” The company has already entered into off-site corporate PPAs for solar power generation and onshore wind power generation. The PPA with Kyuden will be the first for geothermal power generation for Panasonic.
With the introduction of the geothermal PPA, the contribution of electricity from renewable energy sources to the company’s domestic electricity use has increased from 15% to 30%.
Further, Panasonic aims to achieve zero CO2 emissions for all of their factories worldwide by 2028.
Kyuden currently operates four geothermal power plants in Japan – 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.
