Siemens has delivered high-voltage direct-current (HVDC) technology that allowed Red Eléctrica de España (REE) to link Mallorca with the Spanish mainland via an electricity highway laid in the Mediterranian. In the future a significant proportion of the island’s power demand will thus be met using wind, solar and hydroelectric power which is produced on the mainland.
At the same time supply security to the island will be enhanced. This project is representative of a trend in Europe: Power grids are distinctively coming closer together. With HVDC technology renewables-based power can be transmitted over long distances with low losses. HVDC links will become the backbone of power grids. The link laid to Mallorca comprises three single-piece submarine cables, which were supplied by Prysmian together with the cable manufacturer Nexans and laid at a depth of as much as 1485 meters on the Mediterranean seabed.
