Endesa has presented for the first time in Europe, the first recharging point that allows dual directionality of the load, in other words that has the capacity to supply power to the electric vehicle and enable it to provide its energy to the grid. This represents an important step in the development of smart grid electricity in need for tools to optimize production and distribution, to better match supply and demand between producers and consumers of electricity.
The new recharging point features V2G (vehicle to grid) and V2H (vehicle to home) technology, so that the users can either choose between consuming electricity accumulated on their vehicle to circulate, power their home or even sell energy in excess to the electrical system. This innovative system has been developed by Endesa, in collaboration with the center CITCEA of the Polytechnic University of Catalonia (UPC) and the Institute for Energy Research (IREC).
The real tests have been presented at the International Congress on Intelligent Vehicles organized by the Institute of Electrical and Electronics Engineers (IEEE), which was held in Spain for the first time. The recharging point is to be installed in the fourth quarter in Malaga, under ZEM2ALL (Zero Emissions Mobility to All-Zero emissions for all), with another 5 recharging points also bidirectional, 16 fast recharging points and 200 conventional recharging ones.
rn ZEM2ALL is a program led in Spain by Endesa, for a duration of four years and a budget of 60 million euros, thanks to which new services and the advantages of electric mobility in cities will be massively introduced.
The importance of storing and returning energy to the grid
Electricity is one of the little energy that can not be stored on a large scale. This means that, at times, electricity generation from wind farms at night (when usually most active) will need to disconnect. However, all this energy could be used to recharge electric vehicles during the night, making it a much more efficient system. The possibility that the vehicles can pour their energy into the grid when needed (the vehicles are parked most of the time) will balance even better production and consumption.
Endesa and the electric vehicle
For Endesa, the electric vehicle is one of the main ways of combating climate change. Therefore, the company has defined as strategic its electric mobility project, and this is reflected in its 2008-2012 Sustainability Plan. Framed in this plan, the company – part of Enel Group – has created a structure that has allowed the development of technology and agreements which are already yielding their first results: in 2011, Endesa has installed more than 300 recharging points for electric vehicles in Spain and about 20 in Latin America.
