Study 2

Integrated network planning

Introduction

The build-up of the required infrastructure is a very capital-intensive activity. To allow for a commercial operation of the future charging network a cost-effective, strategic and demand-driven expansion is crucial. This holds for the planning of multi standard fast charging network as well as for the network of intermodality hubs of Deutsche Bahn.

Objective as stated in Grant Agreement:

Optimize the planning of the demand-driven network of multi standard fast chargers, ensuring full interoperability, robust ICT services, implementation of relevant standards and energy management requirements, as well as planning, and network integration of intermodality hubs.

The overall research question for study 2 therefore is:

How can integrated network planning be used to ensure optimization towards future profitability of fast charging networks and intermodality hubs?

This question will be addressed in sub-study 2.1 and 2.2

Substudy 2.1 Comprehensive network planning and rolling optimization

An important element of an effective network planning for fast charging is the location selection based on expected revenue and costs. To this end, it is essential to develop a model to identify success factors and evaluate them in order to predict profitability.

Furthermore, inefficiencies that arise from isolated network planning by different market players should be addressed, and connection to cross-regional and cross-national networks should be enforced. In parallel, costs reductions have to be realized for the prolonged process towards location securement, installation and operation through process improvement and strategic decisions based on the experiences in the first phase of the network roll-out.

These topics will be investigated in sub-study 2.1. Insights on network planning and preparation of locations for the entire fast-E network will feed directly into the actual deployment process. In this way, this study will support the optimization of the preparation process for employment.

Ultimately, sub-study 2.1 will include the finalization of the fast-E locations, based on traffic arrangements, local site engineering requirements, final permit processes, and the various strategic parameters influencing the site’s ultimate business case.

Substudy 2.2: Planning of Intermodality Hubs and Service Offerings

In the outlook on sustainable mobility systems, intermodal traffic plays a significant role. Much like the fast charge network, intermodal electric transport it still in its infancy. In the fast-E project, the two concepts are combined, since a number of the multi-standard fast charging stations will be deployed at appealing train stations of Deutsche Bahn. This supports intermodal e-mobility since users can combine public transport with other e-mobility solutions such as e-car-sharing, e-taxi, e-car renting, or private electric driving.

Sub-study 2.2 explores network planning and concept development for intermodal hubs, including infrastructure, location planning and design. The important elements in the preparation phase and the characteristics of intermodal e-mobility hubs will be studied, and based on this the final locations will be chosen. In addition, it is investigated how consumer interest can be improved and how intuitive, easy to use service packages can be created.
