Göteborg Energi, the municipally-owned power company of the city of Gothenburg, Sweden, is collaborating with several entities to explore the vehicle-to-grid (V2G) potential of EVs. 

The company is working with Volvo Cars to investigate bidirectional charging for home use, and how homeowners can contribute power to the local grid from their EV batteries.

In early 2024, Göteborg Energi will begin the test phase of Swedish car brand Polestar’s PAVE V2G project using a fleet of Polestar 3 vehicles. The project will include the participation of Swedish National Grid Authority Svenska Kraftnät, regional energy distributor Vattenfall Eldistribution, charging equipment supplier Easee and Chalmers University of Technology in Gothenburg.

Finally, the collaborative project Public EV Power Pilots (PEPP), part of the city’s Green City Zone initiative, is looking into how vehicles in public environments can be used to store energy to balance the electricity grid through bidirectional charging.

The number of rechargeable vehicles in Sweden has now reached more than half a million, with a total current battery capacity of more than 11,000 MWh, and these figures are expected to grow significantly. “It is estimated that in the future up to 20% of the need for flexibility can be covered by vehicle-to-grid, so the potential is very large,” says Lars Edström, CEO of Göteborg Energi Elnät.
