Hamburg is very much at the forefront of e-Mobility in Germany – in parts thanks to an ambitious government-driven “masterplan” for charging stations. Until the end of 2017 Hamburg deployed more than 600 public charging points at 300 locations throughout the city. An additional 400 charging points are expected to be online until 2019. The goal is to break the catch-22 situation of people avoiding the purchase of electric cars due to the limited charging infrastructure.1
Thanks to a recent public presentation of a representative of Stromnetz Hamburg, the company in charge of building the infrastructure, we now have a much better picture of the public uptake (see the chart below). As you can see, Hamburg has indeed been busy deploying new charging stations at a steady pace. From mid 2016 until mid 2017 the number of public stations grew by more than 50%. This compares to a 36% growth in electric cars in Hamburg within the same time frame.2
Not surprisingly considering these two figures, the number of daily transactions per station remained largely flat with some fluctuation that might be explained by seasonality effects (e.g., increased usage of electric DriveNow cars during winter, higher battery consumption in the cold, …). Similarly, kilowatt hours per transaction stayed roughly flat fluctuating between 9 and 12 kWh.
Striking are the low absolute numbers. At just ~1 daily transaction per station, most stations seem to be heavily underutilized. However, it is important to note that there seems to be a high variability across stations. As remarked in a recently published report of the local government2, some locations see as many as 8 transactions per day.
While it would be nice to see a bigger uptake of the public charging infrastructure, it is great to see that the city of Hamburg is willing to invest for the long-term. More so, it is commendable that Hamburg decided to not just focus on the sweet spots in the city center but to also build locations outside the center. This should greatly help to make the case to the public that Hamburg is ready for the growth in e-Mobility.
