What’s important now?

•Post-2010 is quite important•COP3 target is just one step of 10 to

the final•JWPA proposes 11,800 MW by 2030•NEDO’s Report: Possibly 10,000 MW

by 2020, 20,000 MW by 2030

Challenges Needed

Typhoon accident on Miyako Island (Source: Asahi-Shinbun Web site)

■　 Typhoon attacks

■　 Complex terrain

■　 Lightening attacks

■　 Isolated grid

■ 　 High gust, high turbulent intensity

■ New activities on the following items:

Grid stability

Technical safety

Lightning protection

J-class wind measurements

Wind generation prediction

Japanese Wind Power AssociationJapanese Wind Energy Association YEAR2005　 -　 NEW　

MOVEMENT　 TO　 ATTAIN　THE　 TARGET

1. Micro gird: new subsidy system    2. PPS  by renewable energy3. Combination with battery and inverter:

new subsidy system 4. Demonstration project of hydrogen &

fuel cell 5. Development of J-class turbine against

typhoon, lightning and turbulence6. Accurate forecasting of wind power

generation7. Wind Energy Road Map toward 2030
