Kanden Power Tech

What Kanden Power Tech does

Kanden Power Tech is a Japanese B2B power services company founded in 1956 as Kanden Fly Ash Co., Ltd. and renamed to Kanden Power-Tech Corporation in 2004. It is a wholly-owned subsidiary of Kansai Electric Power Co., Inc. The company specializes in the operation, maintenance, and management of thermal, nuclear, and biomass power plants, with a workforce of 979 employees as of FY2024. Beyond plant O&M, it sells biomass fuels (including PKS and wood pellets) under international sustainability certifications, produces circular-economy byproducts such as FA Sand, and offers solar-related LED products.

The company's revenue base is approximately JPY 17.6 billion (FY2024). Its core customer is its parent Kansai Electric Power, with whom it has long-standing O&M contracts across thermal and nuclear assets; it has also expanded its customer base to include independent power producers such as Ichihara, Sendai, Kamisu, and the Kanda biomass operator, as well as overseas developers through a joint venture with Medco Power Indonesia established in April 2021. The mid-term management plan covering FY2025–FY2027 positions the firm as an energy company contributing to a sustainable society, with planned April 2026 consolidation of the thermal and sales divisions and active overseas growth targeting Indonesia and Uzbekistan.

Kanden Power Tech's revenue model combines multi-year O&M service contracts with Kansai Electric and other operators, product sales of fly ash derivatives and biomass fuels, and emerging overseas service revenue from the Indonesia JV. The April 2025 leadership transition to Takanishi Kazumitsu as President & CEO aligns with the strategic expansion into biomass, decarbonization services (including a CCS/CO2 ship transport demonstration in April 2024), and Southeast Asian operations.
