Therefore, in addition to the ongoing build out of the grid, a variety of flexibility options, such as Vehicle to Grid (V2G) charging, will be crucial to keep peaks at manageable levels. However, by harnessing V2G charging, fleet operators have the potential to earn back significant sums of money. For example, the latest EY study with Eurelectric found that owners of large EVs could save up to £1,475 annually by utilising optimised charging solutions including Time of Use (ToU) tariffs and V2G charging. V2G charging is expected to be one of the most significant electricity flexibility enablers available in the not too distant future – and it represents a significant arbitrage opportunity for fleet operators. If the UK automotive industry does not unlock the potential of V2G charging and maximise its potential, a huge opportunity could be missed.
