International Conference on Ocean Energy (ICOE) 2021
Tocardo is delighted to share the results of a two years multidisciplinary investigations of environmental effects of Tocardo’s tidal power plant in the Eastern Scheldt at ICOE 2021. The ocean energy industry will come together April 28-30, 2021 during the all-virtual ICOE 2021 conference to discuss device innovation, market developments and regulatory affairs to support the commercialization of the sector. This major event is hosted by the National Hydropower Association (NHA), and is supported by the International Energy Agency (IEA) through Ocean Energy Systems (OES).
Multidisciplinary Investigations of environmental effects of the Tocardo’s 1.25 MW tidal power plant
The Oosterschelde storm surge barrier is a dam that contains 62 gates that can be closed during storm surges. In 2015, Tocardo Tidal Power installed a 1.2MW tidal power plant in one of the gates comprising an array of 5 turbines. The presentation at ICOE discusses the methods and results of a unique two-year monitoring program to assess impacts on both the biotic and abiotic ecosystem as well as effects on the reliability of the storm surge barrier itself. The collaborative research project was lead by MET-support on behalf of Tocardo and undertaken by four renowned Dutch research institutes: Wageningen Marine Research, Deltares, Technical University of Delft and University of Utrecht. The Zeeuwse Milieu Federation (ZMF) facilitated regional stakeholder meetings.

About the OP-Zuid program
The collaborative research project was supported by the European Regional Development Fund through the OP-Zuid program 2014–2020 and with financial support from province of Zeeland. Research by TU-Delft was also supported by the Netherlands Organisation for Scientific Research within the research program The New Delta with project number 869.15.008
After the announcement of the acquisition of the Tocardo OTP project in October 2020, we have worked hard to complete the commissioning- and testing phase of this unique project. On Monday 1st February the Oosterschelde Tidal Powerplant, made up of a platform of 5 x T-2, 250kW Tocardo tidal turbines, resumed full continuous operations again. This impressive and iconic Netherlands infrastructure project clearly demonstrates the global potential of energy from water in harmony with the environment.
Macquarie Group, GIG, recently showcased the OTP dam project and its global potential at the Climate Adaption Summit 2021. To see this hard work and project get such recognition makes us all very proud. This Dutch ‘Energy from Water’ initiative is a great example for the future. It showcases an energy solution that integrates nature and has an ability to simply scale up. There are some 400 global tidal deltas at risk of flooding that could benefit from such infrastructure and climate adaptation solutions.
For our clients we apply the learnings that we gain – tide after tide – from our showcase project at the Dutch icon the Eastern Scheldt storm barrier. We have seen the impact our technology and commitment has, and we believe that – working in partnership with QED Naval & HydroWing – we can and will change the world for the better.
Tocardo has come to an agreement on the acquisition of the 1.25MW Oosterschelde Tidal Power Plant, the largest tidal array in the world installed on the Dutch icon Oosterscheldekering. The acquisition follows the successful technical due diligence phase during September 2020. The project is an important step for the global tidal energy sector and for our clean energy future.
The Oosterschelde Tidal Power Plant consists of five T-2 tidal turbines in one of the sluice gates of the Oosterschelde storm surge barrier, with the potential of scaling up. It serves as an international showcase for the tidal energy sector and climate adaptation solutions, combining clean energy production with existing infrastructures and making efficient use of scarce land area.
“At Tocardo we are looking forward to taking this unique project forward to the benefit of the local area in terms of jobs, supply chain development and making an impact to the net zero targets. This exemplar project will be run as a R&D facility and shop window for similar global developments which provides significant export opportunities” – Andries van Unen, CEO of Tocardo.
The timing of the transaction couldn’t be better for the company, especially now that national and local politicians are paying renewed attention to the potential of energy from water in The Netherlands. Dutch Minister Wiebes (Economic Affairs and Climate) has a roadmap to electricity from water in 2030 drawn up, which should be ready before the end of this year.
Tidal Stream Power Generation
Tidal energy is reliable and predictable, and therefore offers flexible baseload energy that powers households when the wind doesn’t blow and the sun doesn’t shine. Beside a significant reduction of CO2 emissions, tidal energy also contributes to a reduction in the emission of all other types of greenhouse gas, such as methane (CH4) and nitrous oxide (N2O). These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce power. Dutch technology developers estimate the technical potential for tidal energy in the Netherlands at 150-250 MW.
Oosterschelde Tidal Power Plant
The entire Oosterschelde Tidal Power Plant consists of five T-2 tidal turbines supplied & designed by Tocardo. These turbines are installed on a single hydraulic lift frame designed, constructed and supplied by Huisman in late 2015. Commissioning was completed with commercial full operation commencing in August 2016. Despite the limited possibilities as a result of the global COVID 19 outbreak, constructive consultations have been held with the parties involved to create a broadly supported solution surrounding the preservation of the installation in the future. The management of Tocardo is therefore grateful to all parties involved for their constructive attitude shown during this period.
The completion of this deal has cost a lot of effort over a long period of time, which is testament to the work put in behind the scenes by the Administrators, Tocardo and Rijkswaterstaat (operator of the Delta Works Barriers). Tocardo also received support from Dutch Marine Energy Centre (DMEC) in helping to present the case for preserving the project.
Tocardo is fully owned by HydroWing Ltd. and QED Naval Ltd. This tripartite, collaborative partnership brings together decades of multi-sector expertise as well as a blend of well tested, complementary products. The joint venture provides a truly end to end service with a spectrum of turbines, foundation systems, marine operations, as well as design, support and service expertise. Tocardo is one of the world’s leading tidal turbine developers renowned for the robust and reliable turbines resulting from a development history spanning the sectors entirety, over twenty years ago, and the largest portfolio of projects operated by any developer in the sector.
Jeremy Smith, MD QED Naval: “This is an amazing opportunity for Tocardo to demonstrate its wares and capabilities. It is also a great platform to introduce further innovations to improve the performance of the turbines and reduce costs. All this whilst producing clean renewable energy into the Dutch electricity grid and generating revenue to sustain the business allowing it to grow rapidly. The size of the prize is significant in Holland but massive when put in the context of a global market opportunities this project opens up.”
Richard Parkinson, MD HydroWing: “Our main objective in taking over the operation of the OTP project is to gain an understanding of how the turbines can be developed and to inform financial models for integration into commercial projects worldwide. This platform is an excellent test bed to develop the turbines while maintaining low OPEX and informing future design developments. Well done to our CEO Andries van Unen for making this complex deal happen.”
Britta Schaffmeister, CEO DMEC: “This marks an exciting stepping stone for the tidal energy sector. Now home to the world’s largest tidal array, the Netherlands is becoming a true frontrunner in harnessing the power of water. Lessons learned here will prove instrumental for more game changers in tidal energy.”
