Project Description

Tidal Technology Center
Grevelingendam (TTC-GD)

When completed in 2018, Tidal Technology Center Grevelingendam (TTC-GD) will provide owners of new technologies in tidal energy with the means to test, certify, validate and demonstrate their products in fully operational tidal context. It will also provide a demonstration setup of 4 turbines capable of producing 0.5 – 1.0 MWe of energy.


Once established in 2018, Tidal Technology Center Grevelingendam (TTC-GD) at the ‘Flakkeese Spuisluis’ in Zeeland (The Netherlands) has the ambition to become the international most cost effective location to test, certify, validate and demonstrate tidal energy converters- technology that generates electricity by harnessing the power of tidal streams. Beyond technology demonstration, testing and verification, TTC-GD provides a wide range of consultancy and research services. TTC-GD is at the forefront in the development of international standards for marine energy, and is forging alliances with other countries, exporting its knowledge around the world to stimulate the development of a global marine renewables industry.


The market for tidal and wave energy is growing fast. This creates worldwide demand for facilities where suppliers may test, certify, validate and demonstrate their innovative systems in a live tidal maritime environment. The Grevelingendam and its tidal sluice ‘Flakkeese Spuisluis’ is part of the Delta Works. It is an ideal location for a test and demonstration facility in tidal energy: Tidal Technology Center Grevelingendam. BT Projects plans to have the center for innovative tidal energy in operation in 2018 and to create with it a platform for the development of the tidal energy industry.


3 test canals of 3.0-10.5 meters width, 5.75 depth

Monitor and data log systems
Verification and validation

4 proprietary turbines,
0.5-1.0 MWe each

2.5 MWe, 2,000 households


Research platform

TTC-GD will feature three (3) test channels into which turbines, mills and their components may be tested, certified and demonstrated. The set-up is ideal for monitoring the impact of tidal energy facilities on morphology, on tidal flow patterns, environmental impact and a host of other variables. TTC-GD will purchase and operate 4 demonstration turbines. These turbines will also be available to research institutes and universities for independent research.

Power output

When not in use by clients, the channels of TTC-GD will have four 0.5 to 1.0 MWe turbines installed for the purpose of demonstrating these technologies and generate electricity for the people in the region. It is estimated that the demonstration turbines will generate electricity for 2,000 households in the region.

Showcasing platform

Easy and cost-effective ‘on-shore’ access
Access to the Blue Barriers facility and the installed turbines can be done from land, avoiding high-cost offshore installation and operational (vessel) costs. It is therefore a perfect low-cost test and demonstration facility, positioned between small-scale tank tests and large-scale offshore demonstrations / arrays. Customers will be able to showcase, test and certify their new technologies at TTC-GD. This also makes it an ideal location to welcome visitors.


TTC-GD is intended to feature ample facilities for research, monitoring and data logging. We are working with various certification and standardization institutions to become a fully equipped center for certification.


Existing facilities in the ‘Flakkeese Spuisluis’ allow us to build TTC-GD within a short timeframe. The tidal sluice is now being completely renovated by the Dutch water authority board Rijkswaterstaat, after which completion of TTC-GD is expected in 2018.

Storage systems for on-demand electricity: ‘Grevelingen on-demand’

In a second phase, TTC-GD will be the perfect place to demonstrate the potential of power storage systems, in order to allow for stable and reliable ‘on Demand’ output strategies. Systems such as water-buffering, flywheel technologies and battery systems are taken into consideration, as well as co-operation with Power-to-Gas systems that are realized in the area. We’ve labeled this mitigated power storage ‘Grevelingen on-demand’.
