Nissan & Endesa Agree To Develop V2G System
Nissan and the energy company Endesa, the largest Spanish utility company, struck an agreement at the Geneva International Auto Show that lays the groundwork for a vehicle to grid (V2G) energy supply that will basically enable EV owners to sell excess energy back to the electric company.
Nissan, the global leader in EV sales with the Nissan Leaf leading the charge, is committed to realizing the full power of EV batteries. The company feels this step supports the entire EV ideal, not just its car. Endesa supports a similar belief:
“The flexibility offered by V2G implementation in terms of storing and releasing green energy into the grid will further enhance the already significant and tangible benefits of electric mobility. This is why Endesa, together with its parent company Enel and partner Nissan, have decided to join efforts in promoting this technology.”
The deal includes the exploration of V2G services in Europe, “second life” batteries, and affordable energy and mobility pack options. “Second life” batteries would give consumers the ability to use their EV batteries as storage vessels after their function as vehicle batteries has expired. The affordable energy and mobility pack options imply the possibility of offering special deals to individuals and businesses with smart energy usage paramount.
Foremost is the idea of offering EV owners the opportunity to profit from clever and planned energy usage; basically, promoting and rewarding the ingenuity and effort it takes to contribute to sustainable energy. For example, an EV owner who provides themselves with solar or wind power would have the opportunity to charge their EV, store energy in their “second life” batteries, and sell this energy back to Endesa. A Nissan representative puts it like this:
“We believe this innovation represents a significant development for Nissan Leaf and e-NV200 customers. Every Nissan electric vehicle battery contains a power storage capability that will prove useful in contributing towards smarter and responsible management of the power demand & supply of local power grids, thus reducing our EV total cost of ownership. Not only does this represent an opportunity for Nissan’s EV private and fleet owners, it could also support grid stability and fully demonstrate that each Nissan EV represents a tangible social asset.”
Many energy management systems will need to search for new ways to maintain grid stability with the rise of renewable energy systems. Striking a balance between suppliers and consumers will be essential in creating sustainable, green energy symbiosis within cities, and EV owners will be given the opportunity to further their impact via this new arrangement and future technology.
The intuitive energy planner would also be able to charge their batteries at low-rate hours, when taxes are lower, and resell the energy at peak hours, netting a profit. Apparently, in Spain, there are different taxes and rates for electricity depending on the time of day and demand? Parts of the US have this as well. On my Con-Edison power bill, however, there is only one rate: too high. Here’s to this practice making it to my area soon….
