12 Dec Danish municipality wants to store power from electric vehicles
As one of the first municipalities in the world, Frederiksberg Municipality wants to store excess power from electric vehicles and deliver the energy back to the grid.
Consequently, the municipality has purchased 10 electric vehicles from the Japanese car manufacturer Nissan, including special charging stations that are known as vehicle-to-grid technology (V2G). These 10 electric vehicles will deliver data to Parker Project to help validate that series-produced electric vehicles as part of an operational vehicle fleet can support the stabilization of the future power grid by participating in advanced vertically integrated smart grid services.
The technology supports the ambition of getting a grid based on renewable energy. Here, the power production will fluctuate depending on e.g. the amount of wind. The two-way solution will also benefit the private economy of electric car owners. According to Peter Bach Andersen, post.doc at DTU Elektro and project manger in the Parker Project, preliminary analyses showed that each car will be able to earn up to DKK 900 a month by being available to the grid:
“The DKK 900 can be held up against the DKK 3-400 a month, which is the typical cost of electricity when dring an electric car, so it is possible to achieve significant savings.”
