JRE Operations Corporation

Office List

Sakata Office

Six members of staff are stationed at our Sakata Office to manage the wind turbines and solar power plants there. Having been born and raised in the local region, they are confident that they have the physical strength and experience required to carry out their duties. Some of them often visit other sites operated by the Group to help conduct facility inspections. With the help of local firms, they carry out inspections and maintenance on the wind turbine bodies and electric equipment.

Regional characteristics

With a population of approximately 100,000, Sakata City is located in an area situated in the north-west of Yamagata Prefecture called the Shonai Region. Surrounded by the Sea of Japan to the west, Dewafuji (Mt. Chokai) to the north, and Dewa Sanzan (three sacred mountains) to the southeast, Sakata City can be found in the Shonai Plain, where the Mogami River, also known as the mother river of the prefecture, runs through. The area is blessed with rich agricultural products and marine foodstuffs from the Sea of Japan and is also known for its production of especially delicious rice and sake.

Nakakyushu Office

Nakakyushu is located in the center of Kyushu. Eight wind turbine units (2000 kW × 8) have been installed along the ridge of Onitayama. The office members employed in this local area carry out maintenance on the wind turbines. Their work mainly involves management and maintenance of the wind farms and the provision of tours for members of the local community.

Regional characteristics

Nakakyushu Wind Farm is located between Gokase Town and Morotsuka Village in Miyazaki Prefecture. As this area is located at high altitude, it is cool in the summer and snow falls in the winter despite it being in Miyazaki. Home to the southernmost ski slope in Kyushu, Gokase Town produces wine made 100% from local grapes as well as Kamairicha (a type of tea that is made using the roast and roll method). Morotsuka Village is the first to begin its mountaineering season in Japan every year, and it is crowded with large numbers of hikers enjoying the blooming Akebono azaleas. It also produces shiitake mushrooms.

Hibikinada Office

Two members of staff are stationed at our Hibikinada Office to manage the wind and solar power plants there. Maintenance of these plants is currently conducted mainly by the O&M firm. However, the staff are now learning new skills every day with the aim of being able to carry out the maintenance on their own in the future. We will contribute to creating a carbon-free society under the slogan of “Change the world with renewable energy.”

Regional characteristics

Hibikinada district, where wind turbines have been installed, was designated as the first Kitakyushu Next-generation Energy Park by the Ministry of Economy, Trade and Industry. Visitors can experience wind, solar, and various other types of power generation and learn about our latest initiatives. The whole district is aiming to become an attraction spot where nature and industry coexist harmoniously. We will continue contributing to the reduction of greenhouse gas emissions.

Shikasaikai Office

Two members of staff are stationed at our Shika Saikai Office to manage the wind farm there. Given the area’s rich natural environment, they sometimes encounter raccoon dogs, boars, deer, and other wild animals near the office. Although the interconnected substation is situated at a remote location, the wind turbines can be seen from the office. With the support of staff members from other Group sites, the staff stationed here are delivering new results every day.

Regional characteristics

Located along the Noto Peninsula, the Sotoura Coast and the Uchiura Coast have contrasting geological characteristics. The Sotoura Coast features violent sea waves caused by strong winds from the continent as well as coastal lines with sheer precipitous cliffs, while the Uchiura Coast features coves with comparatively calm seas since the winds are blocked there. Shika Town, located along the Sotoura Coast, is home to a sandy beach called Masuhoura-kaigan. Also, you can view Mt. Takatsume (height: 341 m), the local version of Mt. Fuji, from this town.

Kamisu Office

The 22 employees who operate and manage this biomass power plant do so on a double-shift basis. When problems occur, as many staff members as possible are called in, regardless of whether it is night or day, to ensure that the power generation is not interrupted. All of the employees are committed to protecting the plant. However, the plant is shut down for two to three weeks during the regular inspections held twice a year to implement problem prevention measures so that normal operations may be continued.

Regional characteristics

Home to approximately 160 companies and 22,000 employees and with a history of approximately 50 years, Kamisu City is the largest industrial area in Ibaraki Prefecture. In light of the recent promotion of renewable energy, more and more wind, solar, and biomass power plants are being constructed. Many people are also engaged in agriculture and fishery, so this city has a good balance of agriculture, fishery, industry, and renewable energy generation. The marine products that the area is well known for are Kashima octopuses and clams.

Tsuruoka Hachimoriyama Office

Two members of staff are stationed at our Tsuruoka Hachimoriyama Office to manage the wind turbines and interconnected substation. Regular maintenance and inspection of the turbines is performed by the manufacturer Siemens, while regular inspections of the substation are performed by the staff together with electrical engineers. The substation forwards the power from the turbines on to the transmission network, so regular maintenance to prevent faults and failures is very important. We are committed to introducing new forms of renewable technology that will help to achieve the rapid decarbonization of society.

Regional characteristics

Tsuruoka City is a former castle town of approximately 130,000 people situated on the Japan Sea, in the southern part of the Shonai Region of northwestern Yamagata Prefecture. It is surrounded by farms and forests, with a coastline known for spectacular sunsets. It also boasts world-class research facilities featuring the latest technology. In this way, Tsuruoka City combines natural beauty, industrial prowess and cultural attractions.
In the southeast part of the Shonai Plain are Mt. Haguro, Mt. Gassan and Mt. Yudono, collectively known as the Dewa Sanzan. These three mountains have been revered as sacred since ancient times. Nearby is the Mogami River, considered to be the “mother river” of Yamagata Prefecture, is renowned as one of the three fastest rivers in Japan. The region is rooted in a traditional food culture that has been utilizing the ingredients nurtured by nature’s bounteous blessings. Today, the people of Tsuruoka maintain a strong affinity with nature and respect for the natural environment.
