José Luis Villate TECNALIA, in collaboration with APPA-Marina


After 4 years of continuous operation with a cumulative production of over 1GWh, Mutriku Wave Power Plant is now ready to host tests related to new concepts of OWC systems (air turbines, electrical generators and control systems).

Wedge Global is leading UNDIGEN+ project based on the industrial scale W1 device. The W1 system is an axisymmetric resonant point absorber with direct drive (linear generator) Power Take-Off and incorporates ten years of technology development and testing. During 2015, the W1 system has kept on testing under open sea tests in the Atlantic Ocean at PLOCAN site (II Phase) as well as testing at the harbour on the Canary Islands (achieving current non-stop ocean tests since January 2014), with promissory effective generation results. UNDIGEN+ is a project partially funded by the Spanish Ministry of Economy and Competitiveness, led by the Spanish tech-company WEDGE GLOBAL, in collaboration with SAES, CIEMAT and PLOCAN. After the satisfactory completion of the planned tests during 2015, and due to the outstanding performance of the system, additional tests have been planned for 2016 (III Phase).

Wedge Global W1 prototype

The Finnish company WELLO installed the PENGUIN II prototype in September 2015.

The objective of this first experiment is to test the structural reliability of a 6m length and 2,4m width device constructed in Finland and assembled at the Taliarte harbour close to PLOCAN headquarters.

The testing phase will be extended through 2016.


OCEANTEC plans to install a low power prototype of its floating oscillating column water wave energy converter connected to the grid at bimep in mid-2016.

The Magallanes project was launched in 2007 setting out to develop a technology capable of extracting energy from tidal currents. The project is in the final stage of assembly and construction of a real scale prototype, 350 tons of weight. Sea trials are expected in 2016. Following a research and development stage, in 2014 Magallanes built and tested a 1:10 scale model, successfully completing official testing at EMEC in Scotland. The technology is based on a floating structure without requiring constructions or pillars in the marine bottom. The project is based on achieving the most efficient, profitable method possible to obtain tidal energy: a sturdily-built, simple installation, capable of producing in any area in the world, with the easiest maintenance system.
