Fully electric bus in Greater Paris

Under this plan, all buses in the most polluted areas of Greater Paris will run on clean energy by 2025. To prepare for this challenge, STIF and Keolis will trial a new type of fully electric bus on the line connecting Versailles and Vélizy.

Zero-emission buses at the heart of residential zones

From May 2017 onwards, Keolis will trial under real conditions a fully electric bus developed by Alstom on line 23 of the Versailles-Vélizy bus network (http://nmpcms-ihm.ctp.prod.canaltp.fr/var/keolis_phebus/storage/original/application/d09ba4198804da5436ff54bc7910a450.pdf). This line connects Versailles Europe to the Vélizy 2 shopping centre. The line is 13km in length and forms part of the Keolis operated Phébus network transporting 1,300 passengers each day. It runs through the heart of residential areas in Vélizy and follows Avenue de Paris which connects the Chateau of Versailles and the town hall. The ‘Aptus’ bus, developed by Alstom ( http://www.alstom.com/press-centre/2017/03/alstom-and-ntl-launch-aptis-a-new-100-electric-experience-of-mobility/), draws on an innovative tram-based design, and “full autonomy” technology to allow the vehicle’s batteries to be recharged at depots overnight.

A study of all aspects of an innovative mobility solution 

An expert in urban transport, Keolis will test the overall performance of Alstom’s electric bus over a one-year period. It will study energy efficiency (energy consumption, recharging, battery, depot recharge processes, etc.) as well as required mechanical and electrical maintenance, the economic modelling of the system and operational costs.

A partnership in sustainable mobility for the Greater Paris region

The trial, a result of the partnership between transport authority, STIF, the municipalities of the Versailles Grand Parc area, and Keolis, falls under the strategy of Grand Paris des Bus and the direction of Valérie Pécresse, President of STIF and the Greater Paris region, to develop a network of “clean” buses. Targets are set for 30% of buses to use clean energy (hybrids, fully electric or Bio-NGV) by 2020, with that target at 100% for the most polluted areas. To achieve this, STIF is working with operators and other industry partners to trial innovative technological solutions that could be rolled out on a large scale in future.

Keolis, supporting energy transition in public transport 

Around the world, Keolis partners with communities to implement transport solutions that respect the environment. Keolis works with local transport authorities to test and implement the most efficient mobility solutions for each community taking into consideration their individual needs. All types of motors and alternate fuel sources are considered including biogas, natural gas for vehicles (NGV), electricity, hybrid technology, and ethanol. The current trial to be undertaken with STIF is a fresh example of Keolis’ efforts to prioritise sustainable mobility.
