The process of replacing old turbines with less but more powerful ones is called repowering. Consequently, energy production is increased and yields may even be trebled even though the number of plants is reduced. Compared with older turbines, the new plants operate at reduced revolutions per minute which gives them a more harmonious look. We look forward to sharing this technological progress with you.

2020/21 wind farms with a total capacity of more than six gigawatts will no longer be covered by the German Renewable Energies Act. An operation of wind turbines outside of the Renewable Energies Act is often not economically viable. Is your project also effected? We can get your current wind farm in shape for the future – from a free of charge site analysis through to the development of a suitable repowering concept up till the dismantling and sale of old wind turbines and the realisation of new turbines.

Increasing Yields

The yield of wind farms has increased large-scale since the 1990s. In 1995, the annual yield of a 500-kilowatt turbine was at about one million kilowatt-hours. Today a five megawatt wind turbine with a rotor diameter of approximately 150 meters achieves the ten- to twelvefold.

Advantages

Repowering offers many advantages for operators and landowners of windenergy plants, but also for citizens.

Advantages for operators and landowners:

• Premature sale of old turbines may compensate remediation costs
• Higher lease income due to larger plants
• Compensation payment for operators, based on the revenue which could have been generated by further operation of the old plant (Renewable Energies Act/Germany)
• Shaping your wind farm for the future: Secure profitability before the coverage of the Renewable Energies Act ends through a repowering concept from juwi. We can find a customised solution for any plant site.

General advantages:

• higher yields due to more powerful plants
• less expensive energy costs
• improved grid integration
• more harmonious scenery due to reduced rpm
• increase of regional income
