Summary/Abstract

By 2011 little is known about the economic rationale of public fast chargers for electric vehicles (EV). This paper aims at providing an insight into the business case of this technology in a case study for Germany. The estimated Return on Investment (ROI) of a public fast charging station constitutes the main contribution. Potential users and organization structures are investigated as well as different tariff types. According to the estimations, the current market outlook seems too uncertain for triggering a large-scale roll-out of fast charging infrastructure. Approximations suggest that investment is hardly profitable at low EV adoption rates, unless investment cost can be severely lowered. Besides competition with alternative charging solutions, the general EV adoption rate is detected as being a main risk factor for investment in public charging infrastructure.

Summary/Abstract

This article presents a quantitative assessment of the need for electricity transmission capacity investments in Germany for 2030. Congestion is analyzed and its possible relief through appropriate grid reinforcements as those described in the Ten Year Network Development Plan (TYNDP) of the European Commission. Congestion is investigated in three scenarios which differ in the location of power resources and the line expansion projects accomplished. Results show that the TYNDP and overlay line projects proposed in 2011 are not sufficient measures to cope with the increasing demand for transmission capacity. The paper also concludes that if power generation resources are moved closer to demand centers grid bottlenecks can be partly relieved by 2030. The introduction of a high-voltage direct current (HVDC) backbone grid does not relieve congestion significantly.
