Country Reports

Ocean Energy is progressing in Spain with the consolidation of three open sea test sites: bimep and the flagship wave power plant at Mutriku with over 1GWh of cumulative produced power so far in the Basque Country and PLOCAN on the Canary Islands. A couple of wave energy technologies under development by Wedge Global and OCEANTEC and several research projects led by TECNALIA complement the Spanish ocean energy landscape.

 

SUPPORTING POLICIES FOR OCEAN ENERGY


NATIONAL STRATEGY AND TARGETS
The Spanish Renewable Energy Plan 2011-2020, approved in 2011, included targets for ocean energy (100 MW of installed power by 2020); however these targets seem now difficult to achieve due to the lack of specific supporting policies for ocean energy.

One Spanish region has defined specific strategies and targets for ocean energy: the Basque Government approved also in 2011 its Energy Strategy for 2020, which included a specific initiative to speed up technology and commercial development of wave energy and set a target of 60MW by 2020.


REGULATORY FRAMEWORK
In Spain no dedicated consenting process exists for ocean energy technologies but there are several legal documents affecting ocean energy projects:

  • The Royal Decree 1028/2007 establishes the administrative procedure for processing applications for electricity generating facilities in territorial waters. Although it focuses on offshore wind, it also includes electricity generation from other marine renewable technologies. This Decree foresees a simplified procedure governed by Royal Decree 1955/2000 regulating energy transport, distribution, commercialisation, supply and the authorisation procedure for electrical power plants.
     
  • Law 2/2013, of 29 May, for protection and sustainable use of coastal amended the previous Coastal Law of 1988. It provides the legal framework for occupation of the territorial sea, as well as governing issues affecting the fishing sector and safety conditions for maritime navigation.
     
  • Law 21/2013, of 9 December, establishes a simplified process on Environmental Impact Assessment for all marine energy projects.


MARKET INCENTIVES
In November 2014, the Basque Energy Agency (EVE) launched a tender of a pre-commercial public procurement for the development of a floating wave energy converter suitable for the Basque coast. In November 2015, OCEANTEC, a Spanish company with two shareholders (Iberdrola and TECNALIA) was awarded by EVE to supply its technology based on a floating oscillating water column concept. This €2.5 million contract will allow OCEANTEC moving forward into a TRL7 stage after testing, during one year, of a low power prototype connected to the grid at bimep.


PUBLIC FUNDING PROGRAMMES
There are several public funding programmes in Spain for research and technology development no specific for ocean energy but applicable for ocean energy in competition with other sectors. However there are a couple of programmes more specific for ocean energy:

  • The Spanish Government, through CDTI (the Centre for the Development of Industrial Technology), together with four regional governments (Asturias, Cantabria, Basque Country and the Canary Islands), has joined the European network
    OCEANERA-NET to coordinate funding programmes between European countries and regions to support research and innovation in the ocean energy sector. Three projects have been funded in Spain under the first OCEANERA-NET call and more opportunities will come with the second call expected in 2016.
     
  • In the Basque Country, a new call to support open sea testing was launched by EVE in 2015. The purpose of this programme is the demonstration and validation of emerging marine renewable energy technologies.

 

MARINE SPATIAL PLANNING POLICY
There is no a specific Marine Spatial Planning (MSP) policy in Spain. Pre-selected areas for ocean energy development have not been defined. Site selection is carried out on a case by case basis. In the Basque Country, in the case of bimep, a MSP approach has been used for selecting the site.


PERMITTING AND LICENSING PROCESS FOR OCEAN ENERGY PROJECTS
The total time needed to obtain approval of an ocean energy project in Spain is approximately two years but this timeframe can vary depending whether an Environmental Impact Assessment is required or not. The new environmental law in Spain aims to reduce the time scale needed for obtaining the Environmental Authorisation, establishing a time period of no more than 4 months, or 6 months if there are justified reasons, thus reducing significantly the time needed for this consenting process. 

Spain, with the participation of AZTI-Tecnalia, is working with other European countries on the RICORE project (Risk Based Consenting for Offshore Renewables). The aim of this project is to establish a risk-based approach to consenting where the level of survey requirement is based on the environmental sensitivity of the site, the risk profile of the technology and the scale of the proposed project. The project, which has received funding from the European Union’s Horizon 2020 research and innovation programme, will run between 1 January 2015 and 30 June 2016


TEST SITES
The Biscay Marine Energy Platform (bimep), an open sea test facility promoted by EVE and IDAE (Institute for Energy Diversification and Saving) in the Basque Country, was officially inaugurated in July 2015 and is now working with the first users who will shortly install several trial devices. An innovative public procurement was tendered by bimep in November 2015 to develop and install a submarine hub for electrical connection.

After the start-up of bimep, EVE is giving Mutriku's wave power plant a new use as test site, which is compatible with the main activity of the plant, that is, to generate electricity from wave energy.
 

PLOCAN offers a marine test site for marine energy converters. The submarine electrical infrastructure is still in the design stage. It will be ready during the first trimester of 2017 offering the required grid connection. The initial capacity is set at 15 MW with a future extension planned up to 50 MW by 2020. The PLOCAN test site was authorized by the Cabinet of Ministers in March 2014 including a marine area of 23 km2 from the coast to 600 m depth.

 


RESEARCH & DEVELOPMENT


Within the OCEANERA-NET programme, TECNALIA is leading a consortium with partners from Spain, Portugal Ireland and UK to develop and demonstrate critical components for monitoring, control and electrical connection for ocean energy. Delivering reliable and cost-effective technologies will be paramount to the ultimate commercial success of Europe’s ocean energy industry. The so-called RECODE project aims to give answer to this challenge by developing a set of industryenabling cost-effective components, specifically designed for reliable and sustainable delivery of ocean energy arrays. The project started in October 2015 and will run for three years.

TECNALIA, in collaboration with OCEANTEC, was awarded £87,271 by Wave Energy Scotland under its
first competitive open call for innovative Power Take- Off (PTO) systems for wave energy. The project SEÒLTA (Survivable and Efficient OLeo-hydraulic assisted Power Take-off) aims at producing a step change in the overall performance of PTO systems used for wave energy harvesting. Particularly, this project phase will characterise and assess the feasibility to wave energy of a novel hybrid PTO configuration that is directly inspired on those used in the automotive sector, which have achieved a significant reduction on fuel consumption (in the range of 30-50%).

In November 2015, a consortium led by TECNALIA in partnership with University of Edinburgh, University of Exeter, University College Cork, Instituto Superior Técnico, OCEANTEC, EVE, bimep, Global Maritime, Iberdrola and DNV, signed a contract with the European Commission under the Horizon 2020 programme to develop the project OPERA (Open Sea Operating Experience to Reduce Wave Energy Cost). OPERA will collect and share two years of open sea operating data of a floating oscillating water column wave energy converter. In addition, the project will be the first open sea experience for four cost-reducing innovations that will be advanced from TRL3-4 to TRL5. Together, these four innovations have a long-term cost reduction potential of over 50%. These are: an efficient turbine, latching and predictive control, a shared mooring system for wave energy similar to those that have reduced mooring costs in aquaculture, and an elastomeric mooring tether that reduces peak loads at the hullmooring connection and thus addresses one of the most pressing challenges for structural survivability of wave energy devices. Documenting and sharing this open sea experience will also induce a step-change in the knowledge of risk and uncertainties, costs and societal and environmental impacts of wave energy.

The consortium brings together world leaders in wave energy research, the IPR owners and most advanced teams to exploit each of these innovations.

TECNALIA is also leading the project ICERMAR, funded by the Basque Government, in collaboration with the University of the Basque Country and the Basque Centre for Applied Mathematics to coordinate research efforts in the field of marine renewable energy (ocean energy and offshore wind) and to increase the impact of this research into the local industry.

Abengoa Seapower continues the development of several activities in ocean energy, including R&D projects in wave and tidal energy, engineering for construction of marine energy projects, and the development of different tools mainly focused on grid and performance of marine energy devices.

Furthermore, Abengoa Seapower’s team has performed a successfully tank testing campaign on a 1:20 scale prototype (TRL 04) of its own wave energy device, Undiplat, based on a multiple oscillating water column (OWC) system. The 1:4 scale prototype (TRL 05) is expected to be tested off the north coast of Spain by the end of 2017 before the development of a full scale prototype.


 


TECHNOLOGY DEMONSTRATION

OPERATIONAL PROJECTS
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).

PLANNED DEPLOYMENTS
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.
