| You drive home and plug in your electric car, telling an app how many miles you need the next day. As you eat dinner, relax and sleep, your energy supplier takes control of your battery, using it to buy power when it’s cheap, selling it back later when high demand pushes prices up. | You drive home and plug in your electric car, telling an app how many miles you need the next day. As you eat dinner, relax and sleep, your energy supplier takes control of your battery, using it to buy power when it’s cheap, selling it back later when high demand pushes prices up. |
| The company offers national and local power grids services from your battery, making more money that it will later split with you, perhaps as “free miles” for your car. | The company offers national and local power grids services from your battery, making more money that it will later split with you, perhaps as “free miles” for your car. |
| This sounds like a far-off vision of the future. But the scenario will be reality next year for British households able to afford a new Nissan Leaf electric car and willing to allow energy firm Ovo to fit a special charger in their home. | This sounds like a far-off vision of the future.

| “The customer has to want to do it and understand it, and allow someone else to have some degree of control over their charging patterns for some form of rewards,” said Tom Pakenham, head of electric vehicles at Ovo. | “The customer has to want to do it and understand it, and allow someone else to have some degree of control over their charging patterns for some form of rewards,” said Tom Pakenham, head of electric vehicles at Ovo. |
| In his view, everyone benefits: individuals, suppliers and energy networks coping with the increasing, but variable, amount of wind and solar power flowing through their cables. | In his view, everyone benefits: individuals, suppliers and energy networks coping with the increasing, but variable, amount of wind and solar power flowing through their cables. |
| “Electric vehicles, like all vehicles, are an under-utilised asset: cars are parked 92% of the time, doing nothing. So why not make some use of it, to allow us to deploy renewables on the grid, and to allow the owner of the car to benefit somehow?” he said. | “Electric vehicles, like all vehicles, are an under-utilised asset: cars are parked 92% of the time, doing nothing.

| It is not just medium-sized challenger companies like Ovo eyeing this emerging opportunity. Big-six firm E.ON launched a tariff last week targeting owners of electric cars, offering electricity at night – when most of the UK’s 100,000 plug-in cars are charged and when energy demand is usually at its lowest – at prices a third cheaper than in the daytime. | It is not just medium-sized challenger companies like Ovo eyeing this emerging opportunity.

| “The next big challenge is going to be how we integrate all these electric vehicles into the grid system,” said Dr Chris Horne, head of origination at E.ON. “In time, you can see how this is a complete change in the way we think about energy, motoring and vehicles.” | “The next big challenge is going to be how we integrate all these electric vehicles into the grid system,” said Dr Chris Horne, head of origination at E.ON. “In time, you can see how this is a complete change in the way we think about energy, motoring and vehicles.” |
| The German firm is exploring the sort of vehicle-to-grid technology being used by Nissan and Ovo. E.ON thinks the concept may begin to become more mainstream in the next decade, boosted by a £20m government fund for projects starting next year, and the greater availability of electric car models – not all are capable of it. | The German firm is exploring the sort of vehicle-to-grid technology being used by Nissan and Ovo.

| This switch, from individuals potentially giving back power to their supplier, as well as taking it, marks the beginning of a whole new relationship between energy company and citizen. | This switch, from individuals potentially giving back power to their supplier, as well as taking it, marks the beginning of a whole new relationship between energy company and citizen. |
| On the one hand, cheaper solar and energy storage at home could, as one researcher at Imperial College recently put it, “bleed revenues from the utilities sector”. | On the one hand, cheaper solar and energy storage at home could, as one researcher at Imperial College recently put it, “bleed revenues from the utilities sector”. |

| “There’ll be a role for energy companies, it’ll just be very different. It could be considerably diminished in terms of energy supply, if you go far into the future,” he added. | “There’ll be a role for energy companies, it’ll just be very different.

| On the flip side, helping a customer with the complex task of exploiting their battery is an opportunity for energy companies to move beyond just supplying electricity and gas, where price is still the main differentiator, into being providers of a range of energy services. | On the flip side, helping a customer with the complex task of exploiting their battery is an opportunity for energy companies to move beyond just supplying electricity and gas, where price is still the main differentiator, into being providers of a range of energy services. |

| “We think people can become their own energy-independent unit and we’re excited by that vision and need to support it. But, obviously, if people don’t buy energy from us, we need to find other ways to have relationships with them, and to supply them with products and services,” said Pakenham. | “We think people can become their own energy-independent unit and we’re excited by that vision and need to support it.

| Robert Llewellyn, the actor and writer, knows all about that changing relationship. An advocate for electric cars and renewable energy, he has had a battery-powered car and solar power for seven years, and the solar panels were upgraded this year. “It’s changed my relationship with my energy supplier – I give them much less money. Since May, I’ve been around 85% powered by solar,” said Llewellyn, best known for playing mechanoid Kryten in Red Dwarf. | Robert Llewellyn, the actor and writer, knows all about that changing relationship.

| “My one house makes no difference, but if there were 5m homes with [solar and electric cars], it would really help the national grid and reduce the costs of generating power,” he said, referring to the £3bn annual cost to consumers of running the UK’s energy networks. | “My one house makes no difference, but if there were 5m homes with [solar and electric cars], it would really help the national grid and reduce the costs of generating power,” he said, referring to the £3bn annual cost to consumers of running the UK’s energy networks. |
| For Llewellyn, electric cars, batteries and solar power are most exciting not at individual level but at community level, citing his Gloucestershire village’s efforts to generate its own electricity. “What’s emerging rapidly is community-owned energy generation and distribution,” he said. | For Llewellyn, electric cars, batteries and solar power are most exciting not at individual level but at community level, citing his Gloucestershire village’s efforts to generate its own electricity. “What’s emerging rapidly is community-owned energy generation and distribution,” he said. |
| This future, where electric cars are used as a key element of our energy system, is not without potential downsides. Vince said he had concerns about the impact on the car battery’s longevity, though Ovo thinks active management of it could even be beneficial. Thinktanks have warned that just six electric cars in one neighbourhood could cause unplanned drops in voltage if they are not charged at the right times of day. And another worry is the social impact of lots of solar- and electric car-equipped homes reducing their reliance on the power grids. | This future, where electric cars are used as a key element of our energy system, is not without potential downsides.

| Tom Edwards, an analyst at energy expert Cornwall Insight, said: “If I install a battery in my home, because I can afford to put a battery in, that means I’m avoiding the cost of using the national grid but my neighbours might not necessarily be, and they’re going to have to pick up the slack that I’m not paying for.” | Tom Edwards, an analyst at energy expert Cornwall Insight, said: “If I install a battery in my home, because I can afford to put a battery in, that means I’m avoiding the cost of using the national grid but my neighbours might not necessarily be, and they’re going to have to pick up the slack that I’m not paying for.” |
| The risk, as he puts it, is that one day, “you’re left with the whole £3bn bill landing on one old lady in Cornwall”. To avoid that, regulator Ofgem is looking at how paying for the energy network might change in the future, such as a phone-line rental-style charge, rather than being based on the amount of energy used. | The risk, as he puts it, is that one day, “you’re left with the whole £3bn bill landing on one old lady in Cornwall”.

| There is also disagreement over whether it’s more efficient to produce and store power at a local level, close to where it’s consumed, or at large central power stations with the energy transmitted over long distances. | There is also disagreement over whether it’s more efficient to produce and store power at a local level, close to where it’s consumed, or at large central power stations with the energy transmitted over long distances. |
| “Making power where it’s used at the home level is the most efficient way to do it because you avoid all the losses of the distribution and transmission system to get it to people,” argues Vince. Under Jeremy Corbyn, the Labour party has made such a decentralised system one of the planks of its energy policy. | “Making power where it’s used at the home level is the most efficient way to do it because you avoid all the losses of the distribution and transmission system to get it to people,” argues Vince.

| For Edwards, it’s not a given that greater energy independence for consumers is a good thing. “[It’s] not necessarily, because the most efficient way to generate electricity is in very large power stations. They will be more efficient than anything you can stick on your roof.” | For Edwards, it’s not a given that greater energy independence for consumers is a good thing. “[It’s] not necessarily, because the most efficient way to generate electricity is in very large power stations.

| One thing Edwards agrees on is that batteries, along with trends such as more renewables and greater digitisation, mean upheaval is coming. “The system will fundamentally change,” he said. | One thing Edwards agrees on is that batteries, along with trends such as more renewables and greater digitisation, mean upheaval is coming. “The system will fundamentally change,” he said. |
