Plans to double grid capacity in north Japan

JAPAN: An 80km extension to the grid is under consideration in northern Japan, in a move that would double capacity in a region known for ample wind resources, but poor grid take-up.

North Hokkaido Wind Energy Transmission is responsible for maintaining the grid in northern Hokkaido, including Wakkanai, the northern-most city in Japan.

If successful, the project could boost grid capacity from 300MW to 600MW, a project participant told Kensin, a Hokkaido-based construction newspaper.

Full-scale works on creating 265 grid towers of between 40m and 60m in height could begin as early as autumn 2018, with a targeted completion of 2021.

The cost is estimated at JPY50 billion ($457 million), with a subsidy for 50% of the cost paid by the Ministry of Economy, Trade and Industry.

The project is a feasibility study, with the possibility of a second round of tests that could boost total capacity in the area to 800MW.
