Efficiency 20301
Sustainability
Present grids can be refurbished to operate at full capacity without
compromising safety
New installations must provide maximum flow of energy to any location in
the grid
In 2020 the fleet of electric cars could reach 40 million world wide, around 2
percent of the cars on the road by then1
The infrastructure for charging the vehicles has to be built
Fast charging options cannot be provided by the current grid infrastructure
The future electrical system must be used at its full capacity
and must be able to cope with new challenges
