Projects that contribute to the natural environment

As an objective of its business management, Red Eléctrica undertakes to contribute to sustainable development and biodiversity conservation, and therefore, amongst other measures, it develops and carries out various environmental and social projects.

The Red Eléctrica Marine Forest: project for the recovery of Posidonia oceanica seagrass meadows

The objective of this R&D+i project, carried out between 2012-2016 in collaboration with the Mediterranean Institute for Advanced Studies (CESIC-IMEDEA), is to study the use of seeds for recovering the Posidonia oceanica sea grass meadows in the Balearic Islands, to alleviate the effects due to works associated to the laying of submarine electricity cables.


In this project an innovative technique is used that consists of a process whereby seeds of this plant are grown and germinated under laboratory conditions and also plant sections resulting from natural fragmentation are cultivated and then subsequently used for replanting in degraded areas of their natural habitat. The replanting is performed using different types of substrate in order to determine which ground is best for the growth of the plant, and regular monitoring is carried out to determine the survival rate and extent of growth of each plant.

Project Goals

  • Promote the conservation of biological diversity, preserving a species that is essential for the sustainability of Mediterranean marine ecosystems.
  • Encourage research, development and use of new technologies and processes, in order to avoid or minimise environmental impacts.
  • Adopt a commitment against climate change.

2018 European Business Awards for the Environment

Red Eléctrica received on the 5th of June, 2018 an honourable mention as finalist of the European Business Awards for the Environment of the Spanish section of the 'Business and Biodiversity' category.

This project has also recently received another honourable mention as finalist of the 2018 European Business Awards for the Environment (EBAE), in the special category 'Business and Biodiversity'.

RGI's 'Good Practice of the Year' Award

On 1 June 2017, the Renewables Grid Initiative (RGI) awarded Red Eléctrica the 'Good Practice of the Year' award in the Environmental Protection category for the Company’s project for the recovery of Posidonia oceanica meadows.

With this technique developed by Red Eléctrica large areas of Posidonia oceanica can be recovered, reversing the degradation of this seagrass species endemic to the Mediterranean and helping in the preservation of an underwater plant that is fundamental for marine life, water quality and the fight against climate change, as it constitutes the sea’s main carbon sink.
