A preliminary but rather brilliant year-long trial in Denmark is demonstrating that parked electric vehicles can help to regulate the power grid. Recharging batteries overnight and during work hours can place stresses on utilities infrastructure and is already changing peak hours and demands but by keeping cars otherwise engaged and active players in their refuelling, the grid could selective reduce, increase or take back energy from the batteries (plus presumably store excess capacity) on this extended grid. As if this was not incentive enough in itself, the exchange—which is something I’m sure we’ll being taking for granted in the near future, can also earn some money for the vehicles owners paid out by the grid’s operators.
