Fiege and innogy develop local load management solution for electric mobility

  • innogy to supply infrastructure and modular e-mobility solution for electrification of car fleet
  • Local load management prevents peak loads, thus reducing costs
  • innogy research project also evaluating benefits of bidirectional charging

The starting point was the customer's wish to equip their company headquarters near Münster Osnabrück Airport with charging infrastructure for electric vehicles. Some vehicles in the car fleet of Fiege Logistik are already electric; however, the company expects an increasing number of employees and visitors to use electric cars in the future.

These expected developments will bring big challenges for the existing infrastructure and the limited grid connection at the site. In collaboration with innogy and other partners, the company thus started a pilot project at its headquarters in Greven.The project is aimed at developing, testing and implementing modular solutions.The challenge is to avoid a cost-intensive grid upgrade and still provide facilities for the company fleet as well as employee and visitor vehicles to be charged on site. In this context, modular means that the charging infrastructure is gradually expanded with different components such as local load management, a PV system and/or battery storage systems. The icing on the cake is the first test of bidirectional charging stations. This will reduce costs, for example by capping existing load peaks.

Fiege has installed charging posts at around 10 per cent of the sites. “The uptake of our electric pool vehicles among our colleagues is good, they like using these cars. The additional electric vehicles that we use as part of the research project are also confirming our assumptions of an increase in demand”, says Kai Alfermann, Director Real Estate & Quality at Fiege. “Therefore we are planning to expand our e-mobility infrastructure and in innogy we have found the ideal strategic partner for this endeavour.” The installation of charging columns is now part of the planning process for construction projects of new logistics centres, the charging infrastructure is to be expanded further.

“The individual solutions build on and supplement each other and, depending on the available investment volume, they can be implemented gradually. Intelligent charging columns will be complemented or even replaced by bidirectional charging points, which will become the new standard. In addition to local load management, bidirectional charging will be another key functionality”, explains Michael Schneider, Strategy & Technology at innogy SE. This technology would make it possible to utilise electricity from the electric vehicles’ batteries to balance out consumption peaks at the company site. The bidirectional use of the electric company car fleet could thus lead to a significant reduction of the company's energy costs.

Michael Schneider: “Customer projects of this type are very important these days because they help us identify and meet the real needs of our customers with the support of the Multi-sites/Large Commercial Customers segment, so that we can build a lasting business relationship.”
