Repowering as part of a sustainable future
At Fritz Schur Energy we have many years of experience in repowering projects. Working towards a greener and more sustainable future is a priority to us and we constantly strive to achieve this in our every day work.
We consider repowering as a core element in the pursuit towards a more sustainable world. If it is possible to replace components and restore vital parts such as the foundations and towers, then we have come a long way in making wind turbine operations an even more sustainable energy source. Therefore, we consider both partial and full repowering as an important part of the future. And we want to continue to play an active role in repowering projects in the years to come.
What does it mean to repower wind farms?
Repowering a wind farm means replacing older, generally smaller, wind turbines with newer, generally larger, and more efficient designs or complete upgrades of the current systems in the turbines e.g. the hydraulic pitch system. New innovations in wind power technology have dramatically increased the power output of new turbines compared with older designs.
The challenge - Repowering King Mountain wind farm in Texas, US
King Mountain wind farm was completed in 2001 and consists of 214 units of legacy Bonus 1.3 MW turbines.
The King Mountain Wind Farm is a 278.2 MW wind farm in Upton County, Texas, United States. 214 legacy Bonus 1.3 MW wind turbines are sited in rows along the south-eastern and north-western edges of a mesa surrounded by deep ravines. Annual electricity production is more than 750 GW.
Dust, sand and high temperatures place extraordinary demands on the wind turbines. Consequently, the design was modified for the desert-like conditions, providing additional cooling and protection against wind-blown sand.
Our retrofit solution - a close partnership between Fritz Schur Energy and Siemens Gamesa
In 2018 however, it was time to update the wind turbines to give them new life and enhance the lifespan of the farm. The update also marked the first 1.3 MW repowering project ever by any manufacturer.
Fritz Schur Energy played a vital role in enhancing and improving the lifespan of the King Mountain Project by delivering crucial technology and equipment to our partner, Siemens Gamesa Renewable Energy (SGRE).
FSE has since 1997 worked closely with SGRE and combined with our extensive know-how and experience we were able to deliver a state-of-the-art solution. FSE’s scope included hydraulic power units (HPU), pitch manifolds, accumulators and hoses. The project was done in close corporation with SGRE and other partners which ensured a smooth operation that gave a successful solution and a happy customer.
