Repowering comprises the dismantling of older existing systems and the construction of new wind power systems of a highly modern standard on the same or neighbouring site. This results in additional, new value added for the site through larger, higher and more efficient turbines and an improved energy yield. New planning guidelines are taken into account in the process with the aim of achieving more efficient wind farm planning. We also achieve a sensible concentration of wind power in suitable locations in planning terms without having to designate new areas.
According to the current Renewable Energies Act, the repowering bonus no longer applies, but this does not automatically mean the end of repowering but only puts it on an equal footing with the planning for a new wind farm as far as remuneration pursuant to the Act is concerned. After approx. 12 to 15 years of operation of a wind farm, the technical condition of the turbines, the yields achieved in the location and the liquidity of the company are all important indicators for an assessment of whether repowering makes sense or whether it should continue to operate as is. The likelihood of obtaining approval, height restrictions, designation of the area as a priority area and similar factors represent further preconditions. This is checked and assessed accordingly and the results discussed with the operators and partners.
wpd repowers together with the operators and investors and leads an existing fund/existing company to higher and renewed value added. There is only a low risk for investors as the conditions in the location are known. Modern turbines and reliable technology are used including a full maintenance concept. The existing turbines are dismantled and successfully sold – via www.windturbinescout.com to name one example.
wpd is currently planning the repowering of five to six further existing wind farms all of which are at various stages of the planning and approval process.
