The system consisting of depleted batteries that will be removed from electric cars and brought together into containers will have a power of 70 megawatts and a storage capacity of at least 60 megawatt hours, which will be derived from 2,000 connected automotive batteries. The capacity of 60 megawatt hours is enough to cover the daily electricity needs of the city with 5,000 households. At the beginning of 2019, the first installations will be installed at Renault's Douai and Cleon factories in France and in the former coal plant in the German state of North Rhine-Westphalia.

The system will primarily serve to harmonize the differences between consumption and production of electricity from renewable sources that are not constant, so that operators can maintain the balance between supply and demand for electricity needed to ensure the appropriate frequency of household electric current. If the demand for electricity is greater than the current production, operators will simply be able to release electricity from storage sites to the grid. As they say in the Renault group, this way of establishing the stability of the supply of electric current will greatly contribute to the attractiveness of electricity from renewable sources.
