1,000 charging stations for Vienna

Individual motorised transport is responsible for 40 percent of Vienna’ greenhouse gas emissions. It is absolutely essential to electrify individual transport for the City of the Vienna to be able to achieve its target of cutting transport-related CO2 emissions to zero by 2050. Surveys conducted by the Vienna University of Economics and Business and Deloitte have shown that a comprehensive network of charging points is the key factor in helping e-mobility achieve its breakthrough. Wien Energie will therefore invest EUR 15 million in the construction of 1,000 additional public charging points by 2020.

Background information

In addition to expanding the private charging infrastructure, a comprehensive network of public charging points is also a key factor in enabling e-mobility to achieve a breakthrough. Practice has also shown here that ensuring that billing for the energy used is conducted in a customer-friendly and understandable way is another key aspect.

By installing 1,000 new e-charging points by 2020, Wien Energie is making a substantial contribution to quality of life and sustainability in Vienna. 500 public charging stations had already been set up by summer 2019. The stated objective is that, by 2020, customers in Vienna will never be more than 200 metres away from a charging station. In an international comparison, Austria (and especially Vienna) is helping lead the way in expanding the network of charging stations.

study conducted by the Vienna University of Economics and Business has revealed that three key needs must be satisfied in order for e-mobility to be attractive on the wider market.

  • Customers would like billing for the energy used (kWh) to be simple, transparent and understandable.
  • Having a comprehensive network of charging stations is absolutely critical in order to be able to guarantee customers the greatest possible degree of flexibility. Both public roadside charging stations and being able to charge at home are of key importance here.
  • Reasons for people shying away from buying an e-car continue to include the range and costs of the vehicles. Although e-cars are much cheaper than combustion-engine-powered cars over their entire lifespan, the cost to purchase one is currently a major deterrent.

Another key factor to help e-mobility achieve a breakthrough is ensuring that charging processes are billed in a customer-friendly, transparent and understandable way. Customers would like the system to closely resemble the one used when filling up with diesel or petrol, where payment is based on the amount of fuel taken. In the case of e-mobility, however, it is precisely this way of billing for energy quantities (in kWh) that represents a major challenge. Legal framework conditions make it considerably more difficult to charge by kWh in a way that complies with the law, which is why most companies bill the time spent by the e-car at the charging station. It should in future be possible to combine kWh-based and time-based tariffs to satisfy customer demands as best as possible. Measuring time is important to ensure that public charging stations are not occupied any longer than necessary.

“Local energy companies have invested considerable sums over the past few years to expand the charging infrastructure. With 5,500 charging points, 3,500 of which in the Austrian Federal Association for E-Mobility (BEÖ) network, Austria is already one of the pioneers in Europe when it comes to the expansion of publicly accessible charging stations.

Our demands

Billing represents the greatest challenge presented when public charging stations are used. According to the laws on metering and calibration, the metered data (here the kWh to be billed) must be displayed directly at the charging point. Given that most of the charging infrastructure already in place does not have such a display, it is not currently possible to bill on the basis of kWh. However, in view of the fact that the charging points operated in Austria have been tested by TÜV, certified and given legal approval, it would certainly be technically possible to bill by kWh.

Customer surveys clearly show that customers increasingly want energy-based billing, something which is being prevented by the current regulatory framework and which therefore represents a major obstacle to e-mobility. As a result, the Metering Instruments Ordinance 2016 (Messgeräteverordnung) must be amended to allow the metering result to shown on a remote display (mobile app or web portal) in addition to being displayed in a window at the charging point.

In order to make it possible for customers to charge their vehicles across borders in a simple, transparent and customer-friendly way, a uniform system for recording, signing and forwarding charging data must be in place. There must also be the possibility for service providers and customers to check the data. It is imperative that this is taken into account when revising the EU Directive on the deployment of alternative fuels infrastructure (2014/94).

In order to create additional incentives, the Austrian Federal Government also resolved to provide funding for public charging stations with the “2018 E-Mobility Offensive”. Depending on charging capacity, projects are given funds of up to EUR 10,000 per charging point, certainly a worthwhile measure and one that, in the view of Wien Energie, it must be maintained in the future.
