Bus2025: RATP’s plan for a 100% eco-friendly bus fleet by 2025

Since 2014, RATP has been engaged in a major technological and ecological transformation with the goal of converting the majority of its fleet to electric-powered buses by 2025: that is what Bus2025 is all about.

vign_bus2025This ambitious plan was developed out of STIF’s determination to eliminate diesel buses from its network in the Ile-de-France region.

By 2025, RATP want to roll out a 100% eco-friendly bus fleet in the Ile-de-France region, including electric and biogas buses, in keeping with targets to reduce greenhouse gas emissions by 20% inscribed in the Ile-de-France urban transport plan.

The energy transition and reducing the impact of climate change are top priorities for RATP.

With Bus2025, RATP will thoroughly transform its industrial facilities (bus depots) and fully engage in the energy transition phase for its bus fleet. This transition is already underway with the purchase of the first hybrid buses, a vital step before the deployment of electric buses.

RATP is committed to reducing greenhouse gas emissions and energy consumption per passenger/km by 20% from the 2004 level by 2020.

The Bus2025 plan will reduce RATP’s carbon footprint by 50%.

Bus2025: Key dates

The energy transition will be conducted in 3 phases:

Today: step up the share of hybrid buses in the RATP fleet. Henceforth, all new bids to tender will be for hybrid, electric and natural gas (NGV) buses.

2015-2017: testing and trial runs of all new electric bus technologies and existing recharging systems. Preparation of the programme to adapt bus depots.

2017-2025: launch of bids to tender for the massive deployment of electric and biogas buses.

RATP’s goal for 2025 is to build a bus fleet that is approximately 80% electric
and 20% biogas, a renewable non-fossil fuel

2015, our first year of experimenting with electric buses

RATP launched a vast trial programme to test electric buses under real operating conditions with passengers for the period 2015-2017. These tests are designed to prepare bids to tender for high volume purchases of electric buses as of 2017, with massive shipments as of 2019.

The first 100% electric bus line by 2016

WEB_13011D032Starting in 2016, RATP will operate a 100% electric bus line with standard buses under real operating conditions. This will be a European first for a fleet of this size. Line 341 (Charles de Gaulle-Etoile - Porte de Clignancourt) will be equipped with about 20 100% electric standard buses supplied by Bluebus, a subsidiary of the Bolloré group. The bus will only be recharged at night, at the bus depot. With an autonomy of 180 km, the buses will be able to circulate without needing to be recharged during regular service hours. Like the current standard bus, these electric buses will have a capacity of over 90 passengers.

Other bus manufacturers will also participate in the trial phase

In addition to the Bluebus project, as of year-end 2015 RATP wants to begin testing other electric bus technologies and recharging systems on two benchmark bus lines with passengers: line 21 (Gare Saint-Lazare - Stade Charlety Porte de Gentilly) and line 147 (Eglise de Pantin - Sevran-Avenue Ronsard).


RATP has signed agreements to test electric buses with three European manufacturers – Heuliez Bus (France), Irizar (Spain) and Solaris (Poland) – and with two Chinese manufacturers that are in joint ventures with European firms –Yutong, in conjunction with Dietrich Carebus (France), and Ebusco. These buses will begin circulating as of late 2015. RATP will test one vehicle per manufacturer.


In addition to testing rolling stock and battery autonomy, RATP is also preparing
to adapt its 25 bus depots by connecting them to the power grid


RATP will be able to rely on its experience in the transformation and distribution of electrical power for its RER, metro and tramway networks, and on its relations with RTE and ErDF. The programme will tackle the problems of hooking up with the ErDF network and/or the RATP network, and will build a power architecture for each bus depot to enable them to transform and distribute energy for an average of up to 200 buses per depot.


Goals of the 2015-2017 trial period

WEB_13011D038Through these tests, RATP will be able to generate feedback on the performance of the powertrain (batteries, engines) and recharging systems, with support from the RATP-EDF partnership signed in 2014.

For RATP, it is also the occasion to measure the repercussions of this new technology on operations (impact on machinists, passengers, local residents, etc.) and maintenance (reliability of rolling stock, changes to industrial and maintenance facilities, and adaptation of the bus depots’ power supply).


The hybrid bus, a transition towards the electric bus

While waiting for electric bus manufacturers to meet all of the technical and economic constraints of operating within a dense urban environment, RATP and STIF are investing in hybrid buses.

Today, RATP and STIF have ordered 523 hybrid buses, of which 63 are already in circulation on the RATP network. By mid-2016, all 523 hybrid buses will be in circulation.

Development of a biogas bus line

Adapting industrial facilities

To increase the number of biogas-powered buses, RATP must adapt its bus depots. In agreement with STIF, the first bus depot to be converted to 100% NGV will be the Créteil site, which has accommodated 90 standard NGV buses since 1999. Since 1 June 2015, these 90 buses have all been powered by BioNGV. By 2016, all 140 of the depot’s standard buses will be fuelled with BioNGV. By 2017-2018, all of the Créteil depot’s some 200 buses, both standard and articulated, will be powered by biogas.

The Bus2025 plan: Key figures

RATP operates 350 bus lines in the Île-de-France region

The RATP bus fleet comprises 4,500 vehicles, 97% of which are diesel buses

60% of its buses comply with Euro 5 standards or higher

RATP, with funding from STIF, will purchase 550 hybrid buses by mid-2016

As of 2016, RATP will equip its first 100% electric bus line

In 2016, all standard buses at the Créteil bus depot will be powered with biogas

17,000 employees (machinists, maintenance staff, and engineers) work in the bus department

1.1 billion passengers were transported by bus in 2014 (+15% in 10 years).

2025 target: a 100% eco-friendly bus fleet comprised of about 80% electric buses and 20% natural gas (NGV) buses

The Bus2025 plan will reduce RATP’s carbon footprint by 50%
