5th Offshore Wind day in Tokyo
The Japan Wind Power Association (JWPA)
■ Brief HistoryDecember 17, 2001: started as a Voluntary AssociationApril 1, 2010 : incorporated as a General Incorporated Association
■ Basic philosophy- to improve the energy security of Japan and contribute to solutions for global
environmental issues including warming- to promote sound growth of the wind power industries at home and abroad- to conduct ourselves with strong awareness of responsibility as an industry group
representing our country- to be accountable and maintain compliance by ensuring the function and ability
to exert influence both internally and externally ■ Composition of Members (as of 19 Dec. 2018)
✔ Number of members:384 companies covering whole wind industry✔ Our members own and operate approx.85% of wind farms in Japan.
■ President of the JWPA✔ Mr. Jin Kato, Vice Chairman, Japan Wind Development Co.
(Former CO-CEO of the MVOW)

As for floating offshore wind:
- 16MW, 4 turbines, 2 projects are in operation (One 7MW turbine is to stop operation in 2019)
- NEDO’s one 3MW turbine is under commissioning. It will start official operation soon.
- Toda Co.’s 22MW project is under development.

MOE Floating WTG National Project
at Kabashima in Goto Islands,
Nagasaki Pref.(GOTO-FOWT)
Hitachi’s
Down wind type
2MW wind turbine
Conducted by Toda Co.
28 Oct.2013: in Operation

MOE: Ministry
of Environment
Relocated and granted to Goto city in 2016
MOE’s national project has finished in Mar. 2016.
The turbine was granted from MOE to Goto city local government.
Toda Co. has moved WTG about 10km southwest from Kabashima to Fukuejima.
Fukuejima has more population(38k) and larger electricity capacity than Kabashima.
It was re-connected to the gridline and started commercial operation in Mar. 2016.
METI approved offshore wind tariff 36JPY/kWh for it. (1st and only case in Japan)
Relocated
(10 km)
