"Repowering" of wind farms
Although these days landscapes with wind turbines have become a common sight in our part of the world, it should be remembered that this is a recent phenomenon. In France, it is only since 2001 that the first turbine fields have been connected to the grid.
The "repowering" project has now started.
Against this background, in the last two years the first generation of wind turbines, often with modest power ratings, have however come to the end of their guaranteed price generation purchase period. The "repowering" project is now started.
In the historic sites where the first wind farms were installed, but also in the farms which are currently under construction, an attempt is now being made to find a new profitability, taking the tangible form of turbines which are more powerful than in the past (on average 50% of additional installed power compared to the first facilities), with a longer lifetime (35 years required currently, compared to 20 years in 2005).
At the tops of the pylons good lubrication and good fluid transfer are factors in favour of reliability of the reducers and of the power conversion systems, and over the last decade Pollard has successfully adapted its pumping solutions to these new constraints being faced by industrial companies in this sector.
