In a groundbreaking development, Indra, a pioneer in vehicle-to-home (V2H) technology, has released early findings from the world’s largest trial of its kind. The results were unveiled by Chief Technology Officer John Fox at the Cenex Expo 2024, a significant event in the UK’s journey toward net-zero transport. This trial is part of Indra’s long-term efforts to explore the potential of domestic bidirectional charging, where electric cars can both charge from and supply energy to a household.

The ongoing research project has equipped over 200 homes in the UK with bidirectional chargers, designed to allow consumers to use energy stored in their EVs to power their homes during peak times.
This reduces household reliance on the grid during expensive energy peaks and facilitates recharging during off-peak hours when energy is more affordable and environmentally friendly. The project has so far enabled households to collectively reduce their electricity consumption during peak periods by more than 100 MWh, a remarkable achievement that could have wide-reaching implications for the UK’s energy landscape.
Unlocking Savings and Energy Efficiency
A major takeaway from the trial is the financial benefit reported by participants. Over half of those involved in the trial have forecast annual savings of between £400 and £799, while some participants are saving in excess of £1,200 per year. These savings are particularly prominent for homeowners who combine bidirectional charging with solar panels. Many have even experienced negative energy bills, earning money through Feed-In Tariffs or Smart Export Guarantee payments for feeding surplus electricity back to the grid.
John Fox, speaking from personal experience, confirmed the real-world effectiveness of the technology. “I’m around the £800 saving per year mark, with no solar panels at my home,” he said, underscoring the potential for the average UK household to benefit from bidirectional charging, even without additional renewable energy sources.
Beyond the immediate financial benefits, the trial is also gathering critical data on user interaction and behaviour, information that will guide the next generation of Indra’s chargers. A particularly innovative aspect of the trial is its partnership with Motability Operations, ensuring that the technology is accessible to disabled people. Their feedback is proving vital in refining the technology’s design to meet a broad spectrum of needs.
The Implications for the UK EV Market
The early results of Indra’s trial mark a crucial milestone in the UK’s transition toward sustainable energy systems. The potential scale-up of V2H technology could significantly alleviate pressure on the national grid, especially during peak times. With EV adoption on the rise, a fully bidirectional EV fleet in the UK could serve as a distributed energy storage system, helping to smooth out demand fluctuations, reduce energy costs, and limit carbon emissions.
By enabling consumers to manage their own energy use more dynamically, V2H technology also helps to democratize energy management, reducing dependence on traditional energy providers. This could further catalyze the shift toward renewable energy, especially when coupled with home solar installations.
As more homes adopt solar panels, V2H technology can facilitate more efficient use of locally generated clean energy, while also contributing excess energy back into the grid. This creates a virtuous cycle of energy efficiency and cost savings, while significantly reducing the strain on energy infrastructure.
As the UK government pushes forward with its ambitious net-zero targets, the implications of Indra’s findings could be vast. Projects like this are laying the foundation for a more resilient, flexible energy system that leverages the growing number of EVs on the road not just as modes of transport, but as integral components of the nation’s energy solution. The trial’s outcomes are also expected to inform future policies aimed at scaling up V2H technology across the country.

An Energy Revolution on the Horizon
Indra’s early results provide a compelling glimpse into a future where bidirectional charging becomes commonplace. If fully realized, V2H technology could transform the role of electric vehicles in our homes and on the grid. Not only would this help stabilize the energy system, but it also stands to make significant strides in cutting carbon emissions as the UK seeks to meet its decarbonization goals.
The potential for financial savings, energy efficiency, and grid stability make this a win-win scenario for consumers, energy providers, and policymakers alike.
