SPAIN: Ingeteam and Istem are to install an energy recovery system in a traction substation of Line L9 of the Barcelona metro. According to Ingeteam, this will be able to recover between 10% and 30% of braking energy.

Ingeteam has supplied the same technology to the metros in Málaga and Bilbao, as well as the light rail network in Bielefeld. In Bilbao, 70% of the energy recovered using the system installed in the Ripa substation is returned to the grid, with the remainder used to power station lighting and escalators. Bielefeld operator moBiel uses two 1 MW units fitted to substations on lines 1 and 4.

Commissioning of five converter and rectifier systems supplied by Ingeteam is underway on Brussels metro Line 2.
