Modernizing a wind farm means more than just putting up more turbines.
Sometimes, old turbines get taken down, and the space gets filled with new turbines that make more energy.
The number of turbines doesn’t change, but the total amount of energy produced certainly does.
That is going to be exactly what happens at the Rethen-Vordorf wind farm in Lower Saxony, Germany.
In the coming months, RWE is planning to remove three of its old turbines and put in three new ones.
Three modern turbines will take the place of the existing machines.
Their impact on electricity production will be entirely different.
The same site will produce far more electricity
At first glance, this might seem like an ordinary maintenance or upgrade of a small wind farm.
There are now three turbines standing at the wind farm.
After the new turbines are installed, there will again be three turbines.
That makes this project so special. This wind farm will look almost identical when it is done.
The size of the site where the turbines sit will remain unchanged.
And yet, this wind farm will be completely changed for another reason.
The old turbines will be replaced by newer turbines that can generate much more electricity from the same site. This is called repowering.
Rather than build out to a new piece of land, developers improve an existing site and use newer, more efficient turbine designs.
Roads, grid connections, and an established project location remain available for continued use.
Construction is scheduled to start soon. Commissioning is slated to occur late in 2027.
The biggest change isn’t going to be seen when you count the number of turbines.
Instead, it will show up in the amount of electricity generated.
Four times the capacity changes the equation
Currently, the existing wind farm produces a total of 5.4 MW of electricity.
With the installation of these new turbines, that figure should jump to 21 MW, nearly four times the current capacity.
Even though the number of turbines will remain the same, the new turbines’ increased capacity will represent a major increase in electricity-generating potential.
RWE expects the wind-farm modernization to increase the overall capacity of the site by nearly four times while utilizing the exact same property on which the turbines are located.
One of the most visible outcomes can be measured in the number of households served.
The company anticipates that the upgraded wind farm will provide enough electricity to meet the needs of roughly 17,000 homes.
Advancements in turbine design offer other benefits.
Repowering projects can reduce the need to expand onto additional land.
Existing wind sites can continue contributing to regional electricity supplies while occupying the same footprint.
The increase reaches beyond the wind farm itself
Financial benefits also exist for local governments around the site of the wind farm as a result of this modernization project.
Under the terms of the agreement with local officials, payments made by RWE would correlate directly to the amount of electricity generated at the site during the year.
Based on anticipated generation levels, those payments could reach up to €165,000 annually.
RWE notes that some portion of those payments is subject to conditions stated within Lower Saxony’s Participation Act.
Another consequence exists as a result of repowering a wind farm.
Local communities could benefit from higher output
Community payments can rise alongside electricity production from the upgraded turbines.
To residents who live near the site, this project involves more than just replacement of aging turbine equipment.
It relates to what that new equipment will produce over many future years.
Three turbines will continue to occupy this property.
The number of turbines will remain unchanged, but their respective capacities will differ dramatically.
