Second-hand wind turbines from Repowering

The successful implementation of wind energy in Europe since the past decade and the continuing economical support by the national legislation has lead to an upcoming market for second hand wind turbines. These plant in the range from 30 to 1000 kW often represent state-of-the-art technology with 10 to 20 years of remaining life expectancy and are available at relatively low initial costs.

This site is still under construction and will be updated continuously. Please contact the webmaster for further information.

Repowering - New Chances for Wind Power Implementation? The successful implementation of wind energy in Europe during the past decade and the continuing economical support by national legislations has led to an upcoming market for second hand wind turbines. Repowering of plant after 5 to 15 years of operation releases a large number of turbines into the market. These plant in the range of 30 to 1000 kW often represent state-of-the-art technology enabling 10 to 20 years of remaining life expectancy and are available at relative low initial costs. For some countries these plant could facilitate project implementation during the market opening period. However, when re-erecting used plant certain precautions have to be taken to ensure high availability of operation. Service and maintenance become more serious issues to be considered at an early stage of project. PDF (21 kB

Contact - WWEA Repowering Working Group

The World Wind Energy Association (WWEA) has founded a permanent working group in October 2004 dealing with the global issues of Repowering. Members of WWEA join world wide knowledge and experience in the Repowering Working Group. AfriWEA will actively paticipate in the activities and represent the African continent. All members of AfriWEA are welcome to contact the coordinator Mr Holger Peters.

Activities of the Working group:

best practice guideline for project realization
