The estimate comes from TMB’s ongoing energy efficiency and sustainability initiatives, which include replacing diesel buses with zero-emission electric and hydrogen models. According to the *Memoria de Sostenibilitat 2023* summary published by TMB, the shift supports broader goals under its Strategic Plan 2025, including reduced energy consumption and lower maintenance costs across the network \[[TMB Sustainability Report 2021](https://www.tmb.cat/documents/525003/5b684f12-8034-4df0-9d0e-3f350ff69238?ref=barna.news), [Sustainability Report 2022](https://transparencia.tmb.cat/documents/525003/de40870c-5e10-4d83-81b0-5a72663e56ad?ref=barna.news)\]. ## Current Progress and Infrastructure Investment As of 2024, TMB plans to operate 232 fully electric buses, 20% of its total fleet, alongside 44 hydrogen-powered units. This includes 78 new electric buses introduced in early 2023, comprising 49 standard and 29 articulated models, costing €46 million \[[TMB News](https://noticies.tmb.cat/sala-de-premsa/tmb-presenta-78-busos-electrics-cami-duna-flota-amb-25-vehicles-de-zero-emissions?ref=barna.news)\]. The H16 and V15 bus lines are already fully electrified, using opportunity charging at terminals via pantograph systems. Each station features a transformation centre and dual 500 kW chargers. The H12 line is next to receive this infrastructure \[[UT16515 Investment Programme](https://www.tmb.cat/documents/525003/2ed03922-660e-eaf8-1267-424e29b511ff?ref=barna.news)\]. Future electric bus acquisitions will use overnight charging instead. > The electrification of the V15 line makes it the second high-demand bus route in Barcelona to run entirely on electric power, following the H16. --- ## Energy and Emissions Reduction Targets TMB’s energy efficiency strategy aims to reduce electricity consumption by 68 GWh annually and prevent 122,000 tonnes of CO₂ emissions each year. These efforts are expected to save €20 million annually in variable energy costs and €7 million in fixed supply charges, amid rising energy prices affecting public transport operators. The energy saved will offset increased demand from expanded metro services, including the central L9/L10 section and planned extensions to lines L1, L3 and L4 \[[Sustainability Report 2022](https://transparencia.tmb.cat/documents/525003/de40870c-5e10-4d83-81b0-5a72663e56ad?ref=barna.news)\]. In addition to fleet upgrades, TMB is implementing regenerative braking systems on the metro network to feed recovered energy back into the grid, further supporting the bus electrification programme. - 232 electric buses by end of 2024 - 44 hydrogen buses operational - €475 million invested in rolling stock over four years - 25% of bus fleet to be zero-emission by 2024 TMB also expects to receive up to €14 million in energy savings certification payments between now and 2028, as reported by *El Periódico* and *CatalunyaPress* based on official projections \[[El Periódico, 28 Sept 2026](https://www.elperiodico.com/es/barcelona/20260928/tmb-preve-ahorro-66-millones-flota-autobuses-barcelona-134742651?ref=barna.news)\]. > This work would not be possible without TMB’s strategic commitment to sustainable mobility and accessible, environmentally responsible transport. --- *Primary sources:* [*noticies.tmb.cat*](https://noticies.tmb.cat/sala-de-premsa/lelectrificacio-completa-de-flota-dautobusos-de-tmb-significara-estalvi-superior-66?ref=barna.news)*,* [*tmb.cat*](https://www.tmb.cat/en/cookies-policy?ref=barna.news)*,* [*Transports Metropolitans de Barcelona*](https://transparencia.tmb.cat/documents/525003/de40870c-5e10-4d83-81b0-5a72663e56ad?ref=barna.news)*,* [*UT16515*](https://www.tmb.cat/documents/525003/2ed03922-660e-eaf8-1267-424e29b511ff?ref=barna.news)*,* [*transparencia.tmb.cat*](https://transparencia.tmb.cat/documents/525003/28813e9b-deb6-7fdf-42f6-e1b0af67fd1a?ref=barna.news)*,* [*Barcelona City Council Press Room*](https://ajuntament.barcelona.cat/premsa/2026/09/25/laia-bonet-participa-a-la-presentacio-de-lestudi-dels-costos-delectrificacio-de-la-flota-dautobusos-de-tmb/?ref=barna.news)*.
