Field test by TransnetBW and Jedlix starts with participation of Netze BW and Next Kraftwerke

  • EV drivers welcome to participate in the field test
  • Market participants welcome as cooperation partners

The transmission system operator (TSO) TransnetBW and the Dutch smart charging platform operator Jedlix are analyzing the potential of electric vehicles for the provision of control reserve in a field test. Two more cooperation partners have joined: the distribution grid operator Netze BW and the control reserve provider Next Kraftwerke.

Next Kraftwerke supports the field test by managing the communication between the vehicle-grid-integration platform of Jedlix and TransnetBW’s grid control system. They will control the vehicle pool according to TransnetBW's control reserve activation.

In its grid laboratory, Netze BW tests how customer-friendliness can go hand in hand with the provision of grid services. The test is done with eight electric vehicles in Ringsheim that have enrolled in the field test. Through cooperation between the two grid operators, the impact of control reserve provision and delivery on the distribution grid will also be investigated.

The project aims to control charging processes in a customer-centric way while delivering control reserve and at the same time respecting current distribution grid capacity to avoid local grid congestion from occurring in the future.

The analyses provide essential insights for grid development at the distribution grid level. Furthermore, the additional measurement data from the grid laboratory will enable validation of the electric vehicle telemetry data collected in the field test.

Further participants sought

Up to 100 electric vehicles from BMW, Jaguar, Tesla and Audi e-tron can participate in the field test. There are still spots available, and new participants are welcome.
The prerequisite is that the vehicles are charged at home in the TransnetBW control area of Baden-Wuerttemberg. Provided the employer agrees, charging at the workplace is also possible. Find information about the field test and the participation requirements at

An expansion of the existing cross-voltage level partnership is explicitly desired. Network operators from Baden-Wuerttemberg are invited to register their interest in the cooperation and participate in the project.

Next Kraftwerke operates one of the biggest Virtual Power Plants in Europe. By utilizing the full potential of digitalization, the company networks thousands of energy-producing and energy-consuming units in the Virtual Power Plant “Next Pool”. Through its technology and trading, clients are able to produce and consume electricity when prices are best for them. By trading their aggregated power 24/7 on different energy spot markets the Virtual Power Plant also makes a substantial contribution to stabilizing the grid by smartly distributing the power generated and consumed by the individual units in times of peak load.
