Red Eléctrica repowers the transmission line between Almonte and Palos de la Frontera

Red Eléctrica de España has invested almost 783,000 euros in the repowering of the 220 kilovolt (kV) line that runs between the electricity substations of Rocío, in Almonte, and Torrearenillas, in Palos de la Frontera.

With the repowering, the transmission capacity of the line is increased without the need to build new infrastructure or modify existing routes, which optimises the functioning of existing infrastructure in an efficient manner, with minimal impact on the territory. In addition, it makes it possible to include other improvements in the infrastructure, such as the installation of bird-saving devices.

In this case, the repowering consisted in increasing the height of the towers, reinforcing the existing tower foundations and adjusting the tension of the conductor cables along a route of 38.4 km, enabling these assets to be available while the work was carried out.

In this way, the transmission capacity of the line has been increased by 30%, which will facilitate the strengthening of distribution and greater security of supply in this province.

The repowering of the 220kV Rocío-Torrearenilla line is included in the 2015-2020 Electricity Transmission Grid Planning approved by the Government.

Red Eléctrica de España has been carrying out this repowering programme for more than 15 years. During this time, more than 5,000 km of 220 kV and 400 kV circuit has been repowered nationwide allowing the overall transmission power capacity to increase by more than 20,000 megawatts.
