Sustainable Energy

In countries like Germany, Denmark, or the Netherlands, wind power is already so widespread that few on-shore sites are left on which new units can be built. Two main paths are being followed to further increase the electrical power generated by wind: building off-shore wind parks, and replacing existing wind turbines with new and larger types (3 to 5 MW). The older, replaced types are appearing on the second hand market and will allow other (developing) countries to start using wind power at lower costs.

The second booming development in wind energy technology particularly affects countries like Denmark and Germany that are running short of productive sites. In these countries, it is more efficient for investors to replace smaller and middle-sized turbines on highly productive sites with new and larger turbines, rather than just building the new turbines on less productive sites. This process is known as “Repowering”.

The successful implementation of wind energy in Europe during the past decade and the continued economical support offered in national legislation has led to a developing 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. For developing countries, this is an opportunity to gain experience in working with renewable energy sources, to establish their own wind energy industries and to profit from technology transfer with low capital expenditure.

This document describes the status quo regarding wind power for several regions and countries in the world, as at the end of 2007, It describes the principle of repowering (as performed in Germany and Denmark) and covers the developing market for used wind turbines.

  1. We are interested in purchasing secondhand windturbines for a project in Romania.
    Each information is helpful.
    Thank you!

  2. To my mind it is important to discuss wind energy technology because we live in one world. It is great to establish wind energy industries and to profit from technology transfer with low capital expenditure.

  3. We are interested in purchasing secondhand windturbines for a project in Ireland.
    can you send me some contact details of where the turbines can be purchased
    Thank you

    Regards,
    Owen
