RusHydro commissions unique wind-diesel project in Tiksi arctic village

December 22, Moscow, Russia. PJSC RusHydro (ticker symbol: MOEX, LSE: HYDR; OTCQX: RSHYY) announces inauguration of 3,900 kW unique wind-diesel power plant in in Tiksi village of the Sakha (Yakutia) Republic. Victor Khmarin, acting Chairman of the Management Board – General Director of RusHydro, Aisen Nikolaev, Head of the Sakha (Yakutia) Republic, Toyohiza Kozuki, Japanese ambassador to Russia, Hiroaki Ishizuka, Executive Director of NEDO and representatives of Takaoko Toko and Mitsui took part in the opening ceremony.     

The wind-diesel complex consists of 900 kW wind power plant, 3,000 kW diesel power plant and 1,000 kW electricity storage system. All components jointly function via automated system controlling and distributing electricity. With annual output of 12 GWh, the facility will ensure reliable electricity supply to the 5,000 inhabitants of Tiksi. JSC Sakhaenergo (a subsidiary of PJSC Yakutskenergo, part of RusHydro Group) will handle operations of the wind-diesel complex.

The wind power plant was put into operation in November of 2018 and since then has proven its effectiveness. Construction of diesel and storage power plants began simultaneously. Over ten thousand tons of supplies have been delivered to Tiski in the course of construction via the Northern Sea Route.

Upon commissioning of the complex, Tiksi will use 500 tons less of diesel fuel every year. Three unique wind turbines manufactured by Komaihaltek are engineered to operate in temperatures up to -50 ºC and can withstand 70 m/s winds. Each wind turbine is 41.5 meters high with blade span diameter of 33 meters. Three diesel units manufactured by Yanmar are engineered to use crude oil, which is considerably cheaper than diesel fuel.

Viktor Khmarin commented: “RusHydro is implementing the modernization program of local power systems in the Far East regions by utilizing hybrid generation - renewables together with diesel generators and electricity storage systems. Tiski is the first hybrid generation project in our portfolio. Our experience in its construction and operation further prove such  projects’ effectiveness within energy service contracts.” He then thanked Japanese partners for the supplied equipment and involvement in the project.

RusHydro has signed the first energy contracts already. By the end of 2021 hybrid generation projects will be commissioned in six isolated residential areas of Yakutia located in the Arctic zone of Russia: Tabalakh, Moma, Sasyr, Tebyulyakh, Kulun-Elbut and Verkhoyansk.

Toyohiza Kozuki, Japanese ambassador to Russia commented: “Tiski wind-diesel project is a great example of international cooperation for promotion of state of the art technologies during the pandemic. It marks an important step forward in adoption of energy efficient technologies in Russia.”

Aisen Nikolaev added: “Commissioning of arctic wind-diesel project is very important for the region as it will improve Tiski’s inhabitants quality of life. Tens of isolated residential areas still exist in Yakutia and we are grateful to RusHydro for modernization of our power system.”

The project initially kicked-off in September 2017 at the Eastern Economic Forum in Vladivostok. In February 2018, RusHydro, the government of Sakha (Yakutia) Republic and NEDO signed an agreement to build a wind-diesel complex in Tiski after which the feasibility studies and preparation of construction site began.
