In line with government guidelines as of September 2022, RATP Group has implemented an ambitious action plan to address the energy crisis. Thus, the Group is participating in general efforts to improve energy efficiency. The action plan to increase energy efficiency supplements the Group’s long-term commitments to achieve a more sustainable, energy efficient and frugal city.
On 11 October 2022, the Group signed the EcoWatt charter implemented by RTE and ADEME to manage strains on the electrical network. In the event of increased power outage risks, RTE will broadcast a warning encouraging French citizens and anyone willing to participate to delay their electricity consumption until after consumption peak hours. By signing the charter, RATP Group fully takes into account the extent of the challenge. The Group commits to delaying charging electric buses and service vehicles whenever possible.
RATP Groups also plans to:
Since transport networks make up 74% of the Group’s energy consumption, they are one of the major focuses of the energy efficiency action plan. All bus drivers are trained in eco-driving to reduce the vehicle energy consumption, starting from drivers’ initial training. Rolling stock and driving software on automated lines have long integrated energy efficiency objectives.
The economic operation project for automated and renovated lines (metro lines 1, 4, 5, 9, 13 and 14) as well as RER line A has generated significant improvements in energy efficiency, with up to 20GWhs saved per year.
The train braking energy recovery system is another lever that was already implemented across the RER and tramway networks and will soon be deployed across the entire network.
Heating represents 40 to 70% of the energy consumption in commercial and industrial buildings. The energy efficiency action plan aims to accelerate the maintenance programmes that facilitate energy savings. At the same time, a verification campaign is scheduled to check that all the temperature sensors on heating equipment are operational so as to ensure that heating is used only as required.
Furthermore, RATP Group uses a novel geothermal system, notably on metro line 11 where the heat recovered from tunnels covers 35% of the heating needs of a neighbouring building. Another such example: the heat produced by data centres is recovered and used to heat the new Châtillon-Bagneux metro workshop.
RATP Group commits to applying government policies on heating, 19°C in winter and 26°C for air conditioning in summer. The heating guidelines were lowered to 19°C for all housing units managed by RATP Habitat.
The Group also works on optimising the energy consumption in buildings according to occupancy throughout the day by improving heating equipment configuration.
To mitigate the Group’s digital impact, several levers are being harnessed and will be strengthened as part of the energy efficiency action plan.
RATP Group monitors the temperature of its data centres to maintain it at 21°C and has launched a curfew programme for electronic devices left on standby, such as screens and photocopy machines, to reduce their energy consumption. The Group also exhausts opportunities offered by digitalisation to reduce its carbon footprint using innovative solutions.
Thus, since 2020, 115 sites and 369 stations have been connected to the OPEN digital platform, a ground-breaking initiative for the steering of water and energy in stations as well as commercial and industrial sites, developed in partnership with Suez. The system provides better consumption monitoring and optimal responsiveness in the event of irregularities.
With 10 million LEDs deployed across its network since 2016, RATP became the first network in the world to be fully equipped with LED lighting. The measure has halved energy consumption related to station lighting.
As part of the energy efficiency action plan, RATP Group commits to reducing outside lighting and to fully switching off lighting in buildings during the night.
The target to reduce energy consumption from advertising displays by 35% between 2022 and 2026 is maintained.
In stations, advertisement displays are switched off between 1 a.m. and 6 a.m. The light intensity of said displays was also reduced to 30%, below the manufacturer standard of 50%.
Moreover, in line with RATP Group’s commitment, in the event of a warning (red EcoWatt alert), all digital advertising displays in stations will be switched off during the day.
In addition to these measures, the Group continues its search for new levers to reduce energy consumption for advertising displays.
The Group has instructed its employees to take the train for any work trip that is less than 3 hours away, and for any work trip less than 4 hours away in the event of missions that last several days. Furthermore, the Group is trialling the use of an electric cargo bike fleet to replace internal combustion vehicles.
The trial notably concerns work trips related to equipment maintenance.
All Group employees are made aware of energy efficiency challenges, notably through the highlighting of eco-friendly habits, a campaign to strengthen the commitment to the energy efficiency policy, climate-themed workshops and webinars on ecological transition challenges.
Employees will also be trained in sustainable digital practices: an e-learning capsule is currently under development for that purpose.
