On 1st October 2008 an extension of the current charging zone around Oslo was established to cover the suburbia Baerum west of Oslo. The new zone is operated separately, which means that vehicles going to Oslo from west will be charged twice. The system is based on the existing system in Oslo, which is fully automatic operated. The motivation for the new charging zone is to provide capital for the operation of the public transport in Oslo and Akershus the next twenty years. Moreover it will provide capital for expansion of the west corridor out of the Norwegian capital.
