Context: Reducing CO2 emissions with renewable energy
In Bergen, Norway’s second-largest city, Keolis Norge operates and maintains the Keolis Group’s first 100% decarbonized bus network: a fleet of 138 buses powered by alternative energies, including 102 electric vehicles. These electric vehicles have introduced a new maintenance challenge for Keolis: it was essential to design an efficient and sustainable battery charging solution to extend their lifespan as much as possible.
In order to cut the CO2 emissions of this fleet by 85% compared to diesel-powered buses over the 10 years of its contract, the subsidiary faced two major challenges. On the one hand, the charging solution ensured that each bus is fully charged every morning so it could run the full service it was planned for, even in harsh winter conditions, and on the other hand, it improved the lifespan of the battery and charging infrastructure.
