Electricity grid to provide support for experimenting and testing new technologies that use marine energy resources to generate electricity and for connecting technologies for observation at increasing depths

The “Electricity grid to provide support for experimenting and testing new technologies that use marine energy resources to generate electricity and to connect technologies for observation at increasing depths (REDSUB)” Project consists of conducting a series of activities that range from the design, acquisition and installation, to the commissioning of a sea-to-shore electricity grid and data network in the area of the maritime-terrestrial public domain reserved for the Ministry of Economy and Competitiveness. The management of this project has been assigned to the PLOCAN Consortium.

The electrical system to be installed is comprised of medium-voltage wiring and it will be designed, fitted and sized to carry an initial maximum of up to 15MW to shore. Most of this comprises an underwater cable, connectors and auxiliary electrical equipment (marine electrical system), which will be laid from the area of the PLOCAN reserve at sea to the sectioning and protection centre located on the coast, which will allow electrical protection between the 13.2Kv sub-station and the devices connected at sea. The transition of the wiring from underwater to terrestrial wiring will be done at this centre, which will connect to a shore-based sub-station to feed the electricity into the distribution grid (terrestrial electricity system).

The main function of the electrical and communications infrastructure is to feed the electrical power generated on the test bed into the distribution network and to transmit data in real time to be processed and analysed in an on-shore control centre. This function is essential for the test bed, because without a connection to the electricity grid, the power generated cannot be fed into the shore grid and the effects and incidents that events at sea could induce in the off-shore energy generation prototypes being tested could not be experienced, which is the basic objective of the test bed.

The REDSUB Project is a single action, in line with PLOCAN achieving the objectives that have been set in its Scientific-Technical Project as a marine USTI. This action encompasses the design, supply, installation and commissioning of the submarine-terrestrial electricity grid and communications network. The system comprises two clearly distinguishable elements: (1) marine electricity system and (2) terrestrial electricity system.

  • This element is based mainly on the design, acquisition, testing, installation and commissioning of the marine electricity grid to evacuate the power generated off-shore. It comprises two hybrid, submarine electricity cables (power, communications and power supply in direct current) with the same technical and building characteristics as the submarine connectors required for connecting the equipment to the marine grid, although they are of different lengths and follow different routes, along with all the auxiliary electrical elements and equipment with their respective marine activities, studies and fitting work to ensure that the REDSUB electricity system works properly and fully.
  • This element is based mainly on the design, acquisition, testing, installation and commissioning of the terrestrial electricity grid to connect the infrastructure from the sectioning centre to the 66kV sub-station. It is comprised of tri-phasic alternating current electrical cable, direct current electrical cable and fibre-optic cable, a power transformer, the characteristic electrical protectors of these installations and all the auxiliary electrical elements and equipment with their respective terrestrial activities, studies and fitting work necessary for the REDSUB electricity grid to work properly and fully.

Information and dissemination activities are scheduled for this entire project, pursuant to the applicable ERDF regulations at all times.

The construction is funded through a grant of the Smart Growth Operational Programme 2014-2020 and by the call for grants to Singular Scientific and Technical Infrastructures (ICTS) of the State Subprogram of ICTS, within the framework of the State Development Program of the Scientific and Technical Research of Excellence of the State Plan for Scientific and Tecnical Research and Innovation 2013-2016.
