148MW Solar Plant Attracts Visitors Through 'Energy Tourism' (page 2)
'Vastness' enjoyed from hill, panel failures discovered by drone
Wind farms equipped with batteries
This monitor tour started from Aomori City and visited wind farms around the Rokkasho Exit of the Shimokita Expressway. Visitors saw a national oil storage station and a nuclear fuel reprocessing plant beyond the bus windows on the way to Rokkasho Visitors Center (Fig. 2 & 3).
Then, the tour members ate local cuisine for lunch, visited a Chinese yam "shochu" distillery, a local specialty, and viewed the "Eurus Rokkasho Solar Park," Japan's largest mega-solar plant, from an observatory on a hill.
Rokkasho-mura was originally known as a mecca of wind power generation. The Futamata Wind Power Plant has large stationary batteries to reduce fluctuations in wind power output. A total of 17 sodium-sulfur (NAS) battery units with a capacity of 2MW each were set up in the site. This is said to be the world's pioneer in wind farms equipped with large batteries (Fig. 4).
After the feed-in tariff (FIT) scheme was implemented, Japan's largest-class mega-solar power plants have been added to these wind power generation facilities. Such facilities include the "Eurus Rokkasho Solar Park" (solar panel capacity: 148MW) by Eurus Energy Holdings Corp and the "Kamikita Rokkasho Solar Power Plant" (solar panel capacity: 71MW) by Sojitz Corp. The Eurus Rokkasho Solar Park is Japan's largest mega-solar plant among those that have already begun operation.
