After having installed an energy recovery system in the Line 9 of Metro de Barcelona, we were awarded with 2 additional systems for Lines 3 and 4. 

The Ingeber systems for Barcelona have an output power of 1.7 MW, as in the Line 9. 

Line 9 project is successfully going under tests.

Bilbao (Spain), Brussels (Belgium), Bielefeld (Germany), Wien (Austria) and Rio de Janeiro have also reduced energy consumption and emissions on railways operations  by installing  INGEBER developed by INGETEAM.
