Sites for the Russia-Japan energy bridge project identified on Sakhalin

On Sakhalin, sites have been identified for the implementation of the Russia-Japan energy bridge project, Sakhalin Governor Alexander Khoroshavin said today at a meeting of the Regional Duma.

“A preliminary decision was made that this would be dedicated generation of alternating and direct current transmission lines. Prospective sites for locating generation facilities on Sakhalin have been identified, and they were selected with the participation of the Japanese side, ”said the governor. In addition, he noted that the Russian government had instructed the regional authorities to make proposals for the inclusion of this project in the state program for the development of the Russian Far East.

The cost of the Russia-Japan energy bridge project (Khabarovsk Krai-Sakhalin-O. Hokkaido) will be approximately $ 5,6 billion.

Earlier it was reported that JSC RusHydro together with RAO ES of the East plan to build Sakhalinskaya GRES-2 electric power 360 MW with the further possibility of expansion. Also in the plans is the modernization of Nogliki GTPP and, possibly, Sakhalinskaya GRES-1, the construction of high-voltage transmission lines and substations with the voltage of 110 and 220 kV.

Thus, by the year of 2020, it will be possible to output about 0,5-0,6 thousands of MW of power to Japan from the power system of the Sakhalin Region. This will require the laying of a submarine cable from Sakhalin to Hokkaido across the La Perouse Strait and the development of the network infrastructure in Japan: the construction of power receiving and transmitting devices in Hokkaido.

The second stage - for the medium term - consideration of the construction of export-oriented generation of coal with a capacity of up to 1 thousand MW in the area of ​​Kholmsk or Uglegorsk (south of Sakhalin), as well as the construction of an additional 500 kV transmission line in the south of Sakhalin.

In the long term (third stage), it is proposed to lay two submarine DC cable lines with a voltage of 500 kV "Mainland of the Russian Federation - Sakhalin" for exporting additional power to Japan from the IES East, including from large generation facilities planned for construction, such as Kankunskaya HPP (1 thousand MW), Nizhne-Timptonskaya HPP (800 MW), Elginskaya GRES (1 thousand 800 MW).

At the second and third stages of the implementation of the energy bridge project, it is assumed that the volume of electricity exports to Japan may amount to 2-4 GW.
