This survey should  be completed by technology developers of low head hydro turbines and tidal stream turbines. We would like your input on four types of new facilities under development in the Netherlands shown on the map to the right;

1. free stream testing in a high speed sluice gate (North of Holland), more info...
2. push testing with a boat in open water (North of Holland),  more info...
3. testing at a sheltered offshore floating structure (North of Holland), more info...
4. testing at a low head impounded site in an existing dam (South of Holland), more info...

The survey has about 20 questions over 2 pages and should take no more than 15  minutes of your time to complete.

TTCG Flakkeese sluice gate

Flakkeese spuisluis

At present a group of initiators, including Oranjewoud, has signed a letter of intent (LOI) with the aim of realizing the Tidal Test Centre Grevelingen (TTCG). The initiators include knowledge institutes, local and national governments and businesses. The TTCG will use the existing Flakkeese sluice gate, located in the Grevelingendam.

The Flakkeese sluice gate consists of six tubes and connects the Grevelingmeer (a lake) with the Oosterschelde (a river connected to the North Sea). The tubes form six independent siphons that are filled with water using a vacuum pump. The water can then flow in either direction, depending on the tides. At present the sluice gate is closed off but its function will be restored in the near future following demands of the local government. The sluice gate will be modified so it can perform multiple functions. The original function is to improve the aquatic ecosystem in the Grevelingenmeer. Moreover the sluice gate will be adapted to provide a facility for research and development of technical systems for energy production from free stream and/or low head water streams. The test centre will be constructed in accordance with demands from market parties. Therefore, it is important to gain insight in the wishes and/or requirement from market parties that are developing systems for free stream and/or low head energy production.
