Under the title of “Developing transmission electricity grids, protecting our seas”, a series of technical workshops are starting today in Palma, which over the course of two days will deal with the development of submarine electricity interconnections in Europe, and their compatibility with marine ecosystems, mainly with the Posidonia oceanica seagrass meadows.

Over the next decade, 40% of the development of transmission electricity grids will be submarine, according to estimates by ENTSO-E, the European Network of Transmission System Operators for Electricity, which makes it crucial to take on a significant commitment to preserve the marine environment in the construction and existence of these infrastructures.

At this workshop, there will be a presentation of the results of the R&Di project, developed by Red Eléctrica together with IMEDEA (Instituto Mediterráneo de Estudios Avanzados), for the active recovery of Posidonia oceanica, which won the 2017 Renewables Grid Initiative (RGI) award for Good practice of the year, and which consisted in the cultivation and planting of specimens originating from fragments and seeds in the bays of Santa Ponsa, Mallorca, and Talamanca, Ibiza, the terminals of the submarine electricity interconnection between these islands.

The workshop has been opened by the General Manager of the Transmission Division of Red Eléctrica de España, Eva Pagán; the Regional Minister for the Environment, Agriculture and Fisheries of the Government of the Balearic Islands, Vicenç Vidal, and the Rector of University of the Balearic Islands, Llorenç Huguet.
