The eFöli project, funded by the City of Turku and TEKES (the Finnish Funding Agency for Innovation) transformed the bus line number 1 of Turku region public transport to operate with electric vehicles. For this purpose, it purchased 6 electric busses which then needed to be powered in an emission-free, relatively noiseless and highly efficient charging environment.
In what could be considered a path-breaking solution for Turku, but a rather straight forward implementation by Heliox, our charging solution comprised DC 50 kW and OC 350 kW. Heliox implemented inverted pantographs as the interface for opportunity charging.
In Turku, since this 2016 pilot project on one line (line 1, from Turku Harbor to Turku Airport), the line is currently almost fully electric with the 6 operating busses. New lines going electric in 2021 are all regional lines, with 3 million passengers annually, and will significantly increase the range of electric public transportation in Turku. Many Finnish cities, including Turku, are aiming to become carbon neutral by 2029.
