TMB strives to be increasingly efficient in the generation and use of energy and to minimise polluting emissions into the atmosphere.
TMB is developing an energy transition strategy to reduce emissions in the networks it operates within the Barcelona metropolitan area.
By progressively making its bus fleet more sustainable
The introduction of 410 buses of different types (46 hydrogen, 210 electric, 154 CNG hybrids), and 120 electric vehicles to renew the auxiliary fleet (cars, vans) is planned by 2024.
By promoting synergies between the metro and buses
For example, the chargers in two of the bus depots will be supplied with electricity from the receiving substations of two metro lines
(9 and 10).
By using green energy
Since 2016, all low-voltage electricity purchased by TMB has come from renewable sources with Guarantees of Origin (GoO). In addition, since 2018, all high-voltage electricity has also come from renewable sources.
Continuously reducing energy use and costs for ongoing operations and maintenance is vital for achieving the energy transition goals.
By reducing the specific consumption of trains, buses and equipment
By securing the cheapest energy and power prices
By using complementary green sources
By designing appropriately to curb/reduce maintenance and operating costs
By recovering energy
One of the main objectives is to reduce energy consumption in the metro by 6% by implementing technologies that allow the energy generated by the trains to be recovered.
