ABB E-mobility has expanded its footprint in public transport electrification with the deployment of 70 high-power chargers now supporting Unibuss operations in Oslo, Norway.
Located in one of Europe’s coldest urban environments, the project demonstrates how high-power electric bus infrastructure can be scaled and maintained under demanding conditions. It offers a model for global cities transitioning to zero-emission transit systems.
The latest installation of 20 chargers brings the total network to 70 units, enabling 1,400 electric bus trips daily. Unibuss, a major transit operator in Norway, serves over 70 million passengers annually across Oslo and its surrounding region.
The new infrastructure supports the city’s goal of fully emission-free public transport by 2028 and contributes to broader national electrification targets.
During the 2024–25 winter season, the system maintained an operational availability of 99.9%. This performance reinforces the reliability of electric transit even in harsh Nordic climates, a key consideration for cities with similar environmental and operational challenges.
To ensure long-term system continuity, ABB E-mobility and Unibuss have formalized a Service Level Agreement that includes 24/7 remote monitoring and on-site field support. This service structure helps maintain availability across a network where consistent uptime is essential to delivering daily mobility at scale.
Currently, more than 90% of the Unibuss fleet operating in Oslo is fully electric. Since 2018, the electrification effort has contributed to a 95% reduction in CO₂ emissions from city bus routes. Additional depot conversions are planned through 2030 to further advance the transition to sustainable transport.
While based in Norway, this deployment illustrates a scalable approach to EV infrastructure that integrates hardware, control systems, and operational support. Cities worldwide aiming to electrify their public transport fleets can look to Oslo as a real-world example of how to execute and maintain electric bus networks under complex, high-demand conditions.
