Nissan announced a major vehicle-to-grid (V2G) trial project with Enel, a multinational power company, in the UK. The automaker has been exploring V2G systems almost as long as the Nissan LEAF program existed and its latest project is the first of its kind in the UK and one of the company's biggest to date.

Nissan and Enel will install and connect 100 V2G units (see picture above) for Nissan LEAF and e-NV200 owners.

The V2G units act as two-way chargers and EV owners will have the option to charge their vehicle or sell the excess energy stored from their vehicle battery back to the National Grid. They will earn an income from the electricity sold back to the grid, all while playing an active role in grid stability.
