UK Drafts £4,000 Credit per Vehicle for Grid-Feeding Tech

The United Kingdom government is considering awarding carmakers a credit valued at approximately £4,000 for each electric vehicle equipped with vehicle-to-grid technology. This proposal emerged from a consultation on the zero-emission vehicle mandate that closed on Friday. The mechanism would allow manufacturers to offset the requirement to sell electric cars, effectively permitting them to sell additional petrol models without facing fines if they miss regulatory targets.

Vehicle-to-grid technology enables electric cars to discharge electricity back into the power grid during periods of high demand. Drivers can automatically charge their vehicles when overnight rates are low and sell surplus power when prices spike. Proponents argue that widespread adoption of this bidirectional charging capability could help balance the grid as the UK transitions to renewable energy sources, reducing the need for expensive gas power plants during periods of low wind or solar generation.

Ben Nelmes, chief executive of the thinktank New AutoMotive, described the technology as exciting but warned that the current incentive structure rewards installation rather than actual usage. He noted that the proposed credit of up to two units, worth around £4,000 each, would provide manufacturers with thousands of pounds per car for hardware that costs only a few hundred pounds. Nelmes argued that many drivers lack the expensive chargers required to utilize the feature, meaning shareholders would benefit more than billpayers.

Vicky Edmonds, chief executive of the Electric Vehicle Association England, cautioned that the industry is moving too quickly. She stated that while millions of electric vehicles are on UK roads, only a small fraction utilize grid storage technologies. Edmonds emphasized that consumers are still focused on immediate concerns such as vehicle cost, charging expenses, and daily suitability. She described it as premature to grant manufacturers credits that effectively allow for fewer electric vehicle sales for a technology not yet tested at scale by drivers.

The National Energy System Operator, which manages Great Britain's grid, forecasts that vehicle-to-grid systems could supply 1.2 gigawatts of power on demand by 2030. This capacity is equivalent to a single power station. By 2050, the operator projects the technology could reach 41 gigawatts, sufficient to meet more than a quarter of peak energy demand. Environmental groups are currently bracing for changes to the mandate that could result in an additional 147 million tonnes of carbon emissions by 2050 if electric vehicle sales targets are cut.

Some drivers already participate in similar programs through companies like Octopus Energy in the UK, Renault in France, and BMW in Germany. Octopus Energy has claimed these services can save drivers £620 annually. The government's review of the zero-emission vehicle mandate aims to adjust sales targets, a move that has drawn scrutiny from campaign groups who fear the new credits will create a perverse incentive for manufacturers to prioritize petrol sales in the near term.
