Report -Business model Repowering

28 January 2023 - Published by Charlotte Lundsberg Baumgartner

The space for wind parks on land is limited and problems occur due to noise, wing shadow disturbance in the vicinity of urban settlements.
Therefore options to at one hand limit the disturbance and at the other hand being able to use the energy to the full have to be discussed.

The North Sea countries are putting more effort in using the sea as part of their ongoing strategy to increase durable energy. Making use of existing and new wind parks in the North Sea means also increasing the capacity of the wind parks already operational.

Due to the increasing demand for renewable energy, the installed capacity needs to be enhanced.

In line with these prospects, governments and companies need to make decisions how to enlarge the output to meet demands. Although new parks still are being developed, we have to look at the existing stock also.

A large number of offshore wind parks will have to make critical end-of-life decisions the coming years. Two end of life strategies have to be considered.

These are:

• Lifetime extension
• Repowering

Lifetime extension means an overhaul, which affects not only the power generation but also the capital and operational expenditures of an overhauled wind turbine.

Repowering as we know it is the complete renewal of the wind park with bigger, stronger high capacity wind mills.
Repowering gives improved feasibility in terms of economic indicators in the long run. For the short run it can give undesirable results for the critical variables.

In this research we will address the possibilities of full repowering.
