Offshore Wind Energy Demonstrator

The Offshore Wind Energy (OWE) Demonstrator is an interactive Dashboard. The Demonstrator has communication purposes with the aim to inform stakeholders on the current conditions of the 19 High Potential Zones for OWE development (in spanish named ZAP – Zonas de Alto Potencial) recently defined in the first Maritime Spatial Plan of Spain (POEM – Plan de Ordenación del Espacio MarítimoRD 150/2023). The interactive map allows to explore how the OWE Sites perform under different spatial indicators and compares OWE sites across planning Demarcations in the Atlantic and Mediterranean, such as distance from shore, collision risk, overlay with existing protected areas etc…This test Demonstrator is meant as a prove of concept and  will be regularly updated as new information gets available along with the other Dashboards that will be developed during the Project implementation.

Data sources, methods applied for indicator construction and literature resources

The Figure below provides an overview of the current OWE Landscape as a function of the sq. km of the OWE array, the minimum distance from shore (in km) and the minimum water depth (in meters) inside the OWE array. The aim of the graph is to provide a graphical understanding of where the HPA OWE Sites are located according to the different POEM Planning Demarcations.

The OWE area indicator describes the area in sq km covered by each of the 19 High Potential OWE Sites of the Spanish Maritime Spatial Plan.



This indicator describes the minimum distance from shore in km. Distance to shore is crucial aspects when analysing and comparing OWE site suitability due to the potential visual impacts to coastal tourism assets, landscapes (Gkeka-Serpetsidaki et al., 2022; Manchado et al., 2019) but distance has also importance for logistics and ports (Filguera-Vizoso et al., 2021). 



This indicator describes the Average Wind Speed in meters/second at 200 meter height.


The indicator describes the portion of OWE Sites (in percentage) overlapping with Priority Use Areas (ZUP – Zonas de Uso Prioritario) for Protection of Biodiversity, reflecting the actual areas of marine protection. For instance a score of 100% indicates that the entire OWE Sites is located inside a marine protected area. In the actual state the indicator does not include the overlap for High Potential Areas areas for conservation of biodiversity (ZAP) that are available on the Visor de Informacion Geografica Marina of the Spanish Ministry for The Ecological Transition and Demografic Challenge (MITECO).


The Collision Risk Index (CRI) describes the intensity of shipping traffic (including tankers, cargo, passenger and sailing) within a radius of 0.5nm – 3.5nm (926m – 6482m) this is deemed tolerable if the risk is being reduced to as low as reasonably practicable (ALARP principle). The CRI is applied using EMODNet Human Activity datasets on shipping traffic and aims to compare how different potential OWE Sites would interact with shipping traffic activities.  


This indicator describes the potential of the OWE Site to be combined with other Blue Economy activities such Aquaculture. A horizontal and multi-sectorial objective of the POEM is the co-existance and promotion of positive synergies among Blue Economy sectors (POEM, 2023). The index was defined as a function of i) level of commercial specialization of the coastal province to aquaculture development was defined by the number of companies active in the finfish, mussel and algae sector; ii) the level of specialization of coastal regions to the OWE sector was calculated by the number of companies in OWE in Spain (Telsnig et al., 2019) and the iii) distance from ports and logistics which is perceived as fundamental constrain in the aquaculture and OWE sector (Riclet et al., 2022 Filgueira-Vizoso et al., 2021). In Spain, several studies and Research Projects promote the Multi-Use of OWE with Aquaculture (Abramic et al., 2023; Weiss et al., 2018; AquaWind Project, 2023; )
