EfficienCE is a cooperation project funded by the Interreg CENTRAL EUROPE programme that aims at reducing the carbon footprint in the region. Most Central European cities have extensive public transport systems, which can form the basis of low-carbon mobility services. More than 63% of commuters in the region are using public transport. Measures to increase the energy efficiency and share of renewables in public transport infrastructure can thus have a particularly high impact on reducing CO2.

This is achieved by supporting local authorities, public transport authorities and operators by developing planning and financing strategies and action plans, implementing pilot actions, developing tools and trainings to plan and operate low-carbon infrastructure, and by transferring knowledge and best practices on energy-efficient measures across Central European regions.

Twelve partners, including seven public transport authorities/companies from seven countries are working together for three years to exploit the untapped potentials in this sector and to contribute to the EU’s ‘White Paper’ goals to cut transport emissions by 60 percent by 2050 and to halve the use of ‘conventionally fuelled’ cars in urban transport by 2030.

Online introduction and Q&A about the pilots in Pilsen, Maribor and Gdynia


Meet experts in energy-efficiency in public transport from PKT, PMDP and Maribor virtually, and learn about their experiences in demonstrating recovery of braking energy, stabilization of trolleybus-grid via buffer storage station, and e-fast-chargers within the EfficienCE project.

Online introduction event on PKT, PMDP and Maribor

Online introduction and Q&A about the Wiener Linien pilot


Meet Lukas from Wiener Linien virtually, and learn about his experiences in implementing the photovoltaic plant on the metro station Ottakring within the EfficienCE project. He will present the pilot also with interesting video materials as an online site visit and participants will be able to ask questions.

Online Event about the implementation of the EfficienCE pilots

We invite you to join our two online events where the implementation process of our pilots will be introduced and participants can also ask questions from the experts.



Register for the efficience final conference

We are pleased to invite you to our EfficienCE final conference, taking place in Leipzig June 10, 2022, where we will present you our project results. 



Plans for more green energy in the trolleybus grid in Gdynia

To increase the share of renewable energy in PKT grid the investment still awaiting implementation is a photovoltaic power plant to be placed on the roofed parking spaces of the trolleybus depot.



Open Call to hardware and solutions providers to present their products on the EfficienCE Toolkit marketplace

An open marketplace, fostering the exchange of new technologies and pieces of equipment, was prepared within the EfficienCE project.



Magyar CIVINET and INTERREG EfficienCE joint event on electromobility

On 24 March 2022, Magyar CIVINET and the INTERREG CE EfficienCE project held a joint on-site meeting in Pécs (Hungary). The one-day event titled „The new directions in electromobility” ended with a site visit to the bus depot.



E-course on energy-efficient Public Transport infrastructure technologies deployment

The project is organising an online course on energy-efficient public transport infrastructure technologies deployment. E-course registration is available here.



Application of Traction Supply System for Charging Electric Cars

The development of electromobility involves the development of electric cars charging infrastructure. The analysis, prepared by the colleagues of Gdansk University of Technology, discusses four options of integrating electric cars chargers with a traction power supply system.



Compensation of Voltage Drops in Trolleybus Supply System Using Battery-Based Buffer Station

An analysis was prepared about the results of a trial operation of a battery-based buffer station supporting a selected section of trolleybus power supply systems in Pilsen.
