Certification for Wind Turbine

In Japan, the Ministry of Economy, Trade and Industry (METI) has introduced a Feed-in Tariff Scheme (FIT) from 1 July 2012. Small wind turbine (SWT) systems with an output of less than 20kW that are confirmed by METI to comply with the provisions of JIS C 1400-2 or equivalent standard (for example, JSWTA0001 which is published by the Japanese Small Wind Turbines Association), are eligible for certain benefits under the scheme. All the electric power generated and supplied to the power grid using SWT systems will be bought by the participating electrical power company at JPY 55/kWh (excluding 8 % consumption tax) for twenty years.

In order to assure conformity of a SWT system to the above mentioned standards, Nippon Kaiji Kyokai (also known as ClassNK) now offers certification of small wind turbine systems attesting to their satisfying the above requirements. This certification is based on the JSWTA0001 standard. The scope of certification also includes the inverter, which often must meet special requirements by Japanese power companies in the case of grid-on type wind turbine systems.

JAB

ClassNK is accredited by Japan Accreditation Board as Product Certification Body for Wind Turbine Products (Type certification of small wind turbine).
