The official ceremony for the opening of the Yongsoo OWC pilot plant on Jeju island took place on  1 July  2016. This plant is a research facility with an installed capacity of 500kW (250kW x 2) and is using two Impulse turbines.

The Horizontal Axis TEC (250 kW) has been installed at Myungrang, Jindo, and it is expected to be tested and  grid connected, during 2016 and 2017.

The research activities with the Floating Pendulum wave energy converter (300 kW) are progressing: the device has been constructed and is expected to be installed on Jeju Island in the summer next year.

The Korea Marine Energy Test & Evaluation Centre (K-METEC) has now two projects for open sea test sites, both funded by the Ministry of Oceans and Fisheries (MOF):

  • Yongsoo-ri, Hankyung-myeon, Jeju - 5 berths (close to Jeju OWC) with 5MW total capacity for testing wave energy converters;
  • On-going TEC Test Bed Project - 5 Berths with 5MW of total capacity for testing tidal current devices; the location has not yet been decided but could be at Uldolmok.

Korea is further developing R&D activities with small oscillating water columns (OWCs) wave energy devices integrated in breakwaters, for application in remote islands combined with energy storage systems. There is an R&D project on this topic funded with USD12 million by the Ministry of Oceans and Fisheriesthat started in May 2016 and will run until December 2020.



In Singapore, regional efforts are being pursuit to develop marine renewable energies in the country. Example of this is the Renewable Energy Integration Demonstrator-Singapore (REIDS), an R&D initiative led by Nanyang Technological University (NTU) and supported by public funds. REIDS will be the first hybrid micro-grid in the region which will incorporate power generation from different renewable energy sources, including ocean energy.

Nanyang Technological University (NTU) is collaborating with EMEC in the development of a tropical marine energy floating laboratory in Singapore. Possible sites for developing a tidal current test site in the country are being investigated.

To understand the regional energy needs and ocean energy technology challenges specific to tropical conditions, a technical working group for ocean energy - Southeast Asian Collaboration for Ocean Renewable Energy (SEAcORE) - has been set up with its neighbouring countries, such as Brunei, Indonesia, Malaysia, Myanmar, Philippines, Singapore, Thailand and Vietnam. This collaboration is a platform for the exchange of ideas, initiatives, and experiences from R&D, policymakers, and industry.

The Sentosa Tidal Test Site project aims to build up the competency of R&D in NTU and Singapore on the harvesting of tidal current energy. The German company Schottel is testing a turbine in the site, a narrow channel between Singapore and Sentosa.



The Basque company Oceantec Energías Marinas, promoted by TECNALIA and Iberdrola, has recently deployed its first Wave Energy Converter (WEC) at the Biscay Marine Energy Platform (BiMEP). The transport to site operation of the WEC, so-call MARMOK-A-5, started early in the morning of October 12th and was towed out along Bilbao river from the Navacel premises to BiMEP. The deployment operations took all day as planned. Since 2012, Oceantec has been working on the development of its own wave energy conversion technology. It is a point absorber based on the Oscillating Water Column (OWC) principle. MARMOK-A-5 resembles a large floating buoy of 5 metres in diameter, 42 metres in length and 80 tonnes weight. The generating system comprises two turbines located in the upper part of the device with a rated capacity of 30 kW. The technology development has been supported by the Basque Energy Agency – Ente Vasco de la Energía (EVE) under a Pre-commercial Procurement Contract.

The testing activities of the WEC are also part of the European project OPERA (‘Open Sea Operating Experience to Reduce Wave Energy Cost’). OPERA, coordinated by TECNALIA, will pave the way for a 50% long term reduction in costs, thus accelerating the establishment of international standards and reducing technological uncertainties and technical and business risks.

The Mutriku wave power plant has completed its first five years of continuous operation reaching a record of cumulative energy produced from waves with more than 1.3 GWh injected into the power grid. Along with reaching this milestone, Mutriku plant, operated and managed by EVE, is also a test infrastructure for OWC components where Oceantec is currently testing its air turbines before installing them in the MARMOK-A-5 device at BiMEP.

The PLOCAN Consortium has recently finalised its central infrastructure, the oceanic platform. It has been constructed in the Nelson Mandela wharf at Las Palmas Port during the last two years.  The deployment at the test site is waiting for the fair environmental conditions. The operation is expected to be completed at the end of November 2016. The Platform is a multipurpose infrastructure that will be located 1.5km from shore, at 30 meters depth. The structure will be re-floated and taken to its final location, where the bedding layer will support the final structure.  The Platform provides workshops, laboratories, classrooms, training rooms and open working areas around a test tank to facilitate sea trials and launching vehicle to the sea.

PLOCAN sea test site (23 Km2) is currently in the installation phase of two submarine medium voltage hybrid cables that will be installed in the first quarter of 2017. These electrical and communication infrastructures will allow to deliver the electricity generated by devices working offshore, during their demonstration stage. The initial capacity is set up at 15 MW with a future extension planned up to 50 MW by 2020. Three wave energy devices have already been tested at PLOCAN without grid connection (Wedge, Wello and Pipo System).

In UK there is a continuing level of political will for ocean energy. There are two relevant funding opportunities for R&D for wave and tidal energy: Supergen and Wave Energy Scotland (WES).

The Supergen UK Centre for Marine Energy Research funds fundamental and applied research in wave and tidal energy. It is a collaboration of all universities in UK mainly to avoid duplication in research, so projects are complementary with each other and cover the following themes: arrays and farms; extreme loadings and durability; novel marine energy system and components; environmental interaction, fatigue loadings and reliability.

Wave Energy Scotland has now nearly 2 years and has funded innovative approaches for Power-Take-Off (PTO), novel wave energy converters device and in July this year launched a third call for engineering design studies into structural materials and manufacturing processes which was closed on 8 September.

Another relevant initiative lead by UK is the EERA (European Energy Research Alliance) Ocean Energy Joint Programme where European countries work together to address the research needs in an order that aligns with the priorities and urgency of the sector, as well as within the means of available funding. It is coordinated by UK with other 8 members (Spain, Portugal, France, Italy, Ireland, Norway, Germany and Denmark).

DOE’s goals for marine energy technology can be summarized as: dramatically reduce levelized cost of energy (LCOE) and rapidly increase the rate of deployments as cost-reduction targets are achieved.

In March this year, DOE announced the 9 finalists (from the 17 teams that completed 1/50th scale testing and were selected from an original pool of 92 registrants) of the Wave Energy Prize. These finalists received funding from DOE to develop 1:20 scale models of their wave energy technologies which were tested over the summer at the Navy MASK basin. On 16 November the winner(s) will be announced at the Wave Energy Prize Innovation Showcase. The public is invited to watch the announcement live beginning at 10 a.m. ET. Join by logging on to Results will also be available at following the event.

The 2017 Presidential Budget Request – USD55 million for marine renewable energies – was the highest in the Water Power Program’s history. U.S. Congress will ultimately determine the budget appropriated to DOE’s Water Power Technologies Office for FY17 in response to this Presidential Budget Request.

To support the full-scale testing of wave energy devices, the Water Power Technologies Office intends to fund the construction and commissioning of an open water, grid connected, fully energetic wave test facility, with at least 3 testing berths, with sufficient infrastructure and support capacity to accommodate simultaneous testing of the number of WEC devices, with approximately 1 MW rated capacity. Any proposed facility should be capable of supporting industry testing for a minimum of 20 years prior to decommissioning. Total amount to be award: Up to USD40 million.

In 2016, a call for more than $20 million in funding for new research, development, and demonstration projects that advance and monitor marine and hydrokinetic (MHK) energy systems, which generate electricity from ocean waves and tidal currents was launched:

  • Topic Area 1: Advanced Technology Integration and Demonstration (USD16.05 million) - addressing wave/tidal/river technologies and demonstration in full scale open water tests for at least 1 year.
  • Topic Area 2: Innovation, testing, and validation of MHK environmental monitoring instrumentation performance (USD5.95 million) - supporting the progressive testing, innovation and validation of instrumentation for cost-effectively monitoring potential environmental impacts of marine energy devices (acoustic outputs, electromagnetic fields, marine life monitoring and Integrated Sensor Packages).

In August, DOE announced the 10 organizations selected. To preview the selected projects see

DOE is supporting companies testing their wave energy devices at the Navy’s WETS at the Marine Corps Base Hawaii, Kaneohe Bay. The following companies: Northwest Energy Innovations, Ocean Energy, Columbia Power Technologies are receiving support for design, fabrication and testing.
