The technical development within the transportation sector is expanding rapidly,where electric vehicles stand as an important part of achieving the European Union’s climate goal, targeting a fossil free vehicle fleet. Participants having a key role within this transformation are taxi operators, who replace their vehicles every third to sixth year. This indicates that taxi operators not only have the opportunity to turn their fleet into an electrical one but also have the opportunity to do so rapidly. The three largest taxi operators in Stockholm, Sweden all strive towards a fossil free taxi fleet 2025. The implementation of an electric taxi fleet therefore poses as a likely solution for reaching the declared goal. From this aspect it is interesting to further investigate how an electrification of the taxi fleet may affect the electrical grid, based on charging behavior and driving patterns in Stockholm county. The results of the study illustrate that the charging patterns of the taxi vehicles in apartment, villa and airport areas will increase the load on the electrical grid foremost during the winter months. Moreover, in industrial and commercial areasthe load will increase throughout the year. In addition, electric taxi vehicles will foremost charge within the city center and at Arlanda airport. The results show that the largest power use takes place in the middle of the day, which contributes to power peaks caused by coinciding load on the electrical grid. Furthermore, the energy consumption persquare meter decreases as the distance from the city center increases.
