Chugoku Electric Power

The company operates a diversified generation portfolio across the Chugoku region of western Honshu. Thermal plants burning coal and LNG — including Misumi, Yanai, and a co-firing unit at Hofu — provide the majority of output. The Shimane Nuclear Power Station in Matsue has been offline since the 2011 earthquake but is undergoing a safety review for potential restart. Biomass capacity at Onahama (Fukushima) and Hofu supplements the fossil fleet.

Yamaguchi Prefecture holds a 9.46% stake and the Government of Japan owns 8.78% through a ministerial holding structure. These positions reflect the company's origins as a state-owned utility that was partially privatized in 1951. The remaining shares trade publicly on the Tokyo Stock Exchange with no single controlling private shareholder.

Yes. The firm has invested in Energy Fiji Limited through a co-investment structure with the Japan Bank for International Cooperation (JBIC), giving it an equity stake in a Pacific island utility. The deal signals a willingness to deploy balance-sheet capital in overseas regulated energy infrastructure, though disclosed international positions remain small relative to its domestic asset base.

Shimane Unit 2 returned to commercial operation in September 2024 after meeting Japan's revised safety standards (per World Nuclear News). Unit 1 was permanently shut down in 2015 and is being decommissioned. Unit 3, a new build, was partially constructed before work halted in 2011; its future remains unclear.

The company pursues decarbonization through three channels: reintroducing nuclear power, co-firing coal plants with biomass (Hofu, Onahama), and developing CO2-SUICOM — a carbon-negative concrete produced in partnership with Kajima Corporation. Unlike some peer utilities, it has not announced a full exit from coal generation.
