Windenergy Goeree-Overflakkee

As a wind-rich coastal province, the province of South Holland is committed to sustainable wind energy. The government has also indicated that it wants to have wind turbines on land in the South-Western Delta. To make wind energy a success, it is important to carefully weigh potential locations. After all, wind turbines have a major impact on the landscape. They are not in place everywhere. The design, the arrangement of the turbines, is very important and can make the difference between acceptable or unacceptable. In certain cases, wind turbines can strengthen the landscape and contribute to identity and readability.

The question that was initially included in this study is: how much MW of wind energy can be situated in the peripheral zone of the island, considering among other things the landscape and cultural-historical characteristics and qualities and the placement requirements for wind turbines? In this study we look at whether the 200-300 MW target is feasible on the basis of the placement criteria given in the Wervelender Policy Document. We use the average target of 250 MW as the starting point. We then investigate which different spatial options are conceivable for the realization of that objective and what impact they have on the landscape and cultural history.

The Wervelender Policy Document (2011) states where wind energy is desired, or is required under certain conditions, or is undesirable. A concentration area is indicated on Goeree-Overflakkee. This concerns: zones linked to large-scale infrastructure (dams, dikes) and large-scale dividing lines between land and water in the southern part of the province. According to the Wervelender Policy Document, this placement area is also ideally suited as a concentration area for wind energy (wind farm), namely the peripheral zone of Goeree-Overflakkee.

This area is considered as a preferred location, with special attention to spatial quality, including sufficient views. Safeguard areas are Natura 2000 areas, the EHS and protected natural monuments, due to ecological values. The head of Goeree-Overflakkee, with the coastal dune area valuable for nature and recreation, and the Delta waters around the island are thus protected from wind turbines.

landscape concepts

After analyzing the landscape and taking into account the placement criteria of the Wervelender Policy Document, we distinguish three landscape concepts:

We call the first the Nieuwland concept. In this concept we choose to use wind energy as much as possible in the younger polders. The oldest polders, such as the Polder Roxenisse, Polder Dirksland, Polder the Oudeland of Sommelsdijk / Polder the Oudeland of Middelharnis, Polder the Oudeland of Oude-Tongen, Polder the Oudeland (Ooltgensplaat), remain free of large-scale wind energy. These polders are the most culturally and historically valuable, here are the old cores that are connected to the open water with their harbor canals.

We call the second concept the Portal concept. This is aimed at accentuating with wind energy from the entrances to the island.

The third concept is aimed at accentuating the the Neck that forms the connection between the Kop (head) van Goeree and the Romp Flakkee.

The concepts have been translated into 5 designs for 3.4 MW turbines and 5 designs for 6 MW turbines. 1 elaboration is discussed belowThe report can be consulted for the other elaborations.

elaboration Nieuwland line: 3,4Mw

The line arrangements are designed in such a way that there is an alternation of wind turbine lines and open sections, because of the note from Wervelender that special attention must be paid to sufficient viewing. The line segments never cross the border of polders and thus tie in with the rhythms present in the landscape. Line configurations fit well with the shape of the Nieuwland polders. We have limited ourselves to straight lines in line configurations and not to follow topographical data such as winding dikes.

We chose this because it provides the most tranquil image. Moreover, the Nieuwland polders are often elongated and often have tight straight dikes.

The distance between the masts is 364 m. The maximum line for the 3.4 MW set-up consists of 8 turbines (with a total length from mast to mast of 2548 m). The shortest designed line consists of 4 turbines (with a total length from mast to mast of 1092 m).
