Vehicle to grid (V2G): What does it mean?

Sending electricity from an EV to the electricity grid.

Vehicle to grid (V2G): The long answer

Vehicle to grid (V2G) is a car-related term that refers to the technology that allows electric vehicles (EVs) to not only draw power from the grid but also to send power back to the grid when needed. In the UK, this concept is gaining traction as more drivers are adopting EVs, and the demand for renewable energy sources is increasing.

With V2G technology, UK drivers can charge their EVs during off-peak hours when electricity demand is low, and prices are cheaper. Then, during peak hours when electricity demand is high, EVs can supply stored energy back to the grid, helping to stabilise the energy supply and reduce strain on the grid.

This two-way flow of power benefits both the driver and the wider energy system. Drivers can potentially earn money by selling excess energy back to the grid, offsetting the cost of charging their EVs. Additionally, V2G technology supports the integration of renewable energy sources, such as wind and solar, by providing a flexible storage solution for their intermittent output.

Furthermore, V2G can contribute to reducing carbon emissions in the UK by utilising EVs as mobile energy storage units, excess renewable energy can be stored and used at times when renewable sources are not generating enough power. This helps to further decarbonise the electricity grid and move towards a more sustainable energy future.

Overall, V2G technology in the UK is an exciting development that allows EVs to not only be a means of transportation but also active participants in the energy system, promoting renewable energy integration and offering benefits to both drivers and the wider community.
