Ushering in The Home Age: E.ON Next calls on government to support a new battery-powered era to cut energy bills and accelerate clean power ambitions
A national rollout of home batteries is key to cutting energy bills in the short-term and achieving the government’s ambition of clean power by 2030, according to a new report.
- Home batteries, when combined with time-of-use (ToU) tariffs, cut energy bills by around £255 a year for the average household, while homes using more energy for medical needs can save approximately £600 a year
- The figures come from The Home Age, a new report from E.ON Next, which captures learnings from a battery pilot in partnership with Coventry City Council
- Based on the findings, E.ON Next is calling for £600m of energy sector investment to support the installation of 250,000 home batteries in the country’s most fuel-poor households
- Home batteries, when combined with ToU tariffs, could save fuel-poor households around £753m a year on their energy bills and all UK households £5.45bn a year, economic analysis shows
- Improving energy flexibility in UK homes is key to achieving national clean power ambitions, E.ON Next believes
A national rollout of home batteries is key to cutting energy bills in the short-term and achieving the government’s ambition of clean power by 2030, according to a new report.
The Home Age, published today by E.ON Next, analyses the results of the company’s first-of-a-kind battery pilot in partnership with Coventry City Council. Homes in the city were given upgrades including batteries, solar panels, insulation, and energy-efficient white goods, as well as being placed on a time-of-use (ToU) tariff to incentivise energy usage when there is less demand on the grid.
Bill savings spark call for government investment in batteries
The results of The Home Age study highlight the financial savings for Brits who have batteries installed and switch to a ToU tariff. On average, each participating household in the E.ON Next Coventry pilot is saving approximately £255 a year* on their energy bills due to batteries alone. For larger families, whose energy needs are typically twice those of the average household, bills reduce by around £415 a year.
Potential savings for households with medical dependencies, such as kidney dialysis machines, are even higher. One such family participating in the Coventry pilot has seen their energy bills fall by the equivalent of £600 a year.
On the back of these figures, E.ON Next has issued a call for government to support the installation of batteries in 250,000 homes where residents are in fuel poverty. The Home Age report highlights that government investment of £600m would support lower income families by ‘reducing their bills, helping them to heat their homes more affordably and protecting them from price volatility’.
A national home battery rollout would have strong economic benefits and consumer support
As part of The Home Age report, E.ON Next worked with Development Economics to calculate the benefits of a nationwide programme to rollout batteries and ToU tariffs. Based on the savings from the Coventry pilot, it estimates:
- If every household in the UK in fuel poverty received the upgrades, bills for these people would fall by £753m** a year, cumulatively
- Batteries and ToU tariffs in every UK home, excluding flats, would see total energy bill savings of approximately £5.45bn a year, and the nation’s energy use drop by 3,174 GWh per year (roughly equivalent to the annual power consumption of all homes in Greater London combined)
- For each £1m saved through energy cost reductions across the country, the nation’s finances would benefit from an estimated £186,000 in Gross Value Added (GVA) and nine new jobs would be created
Support from the general public would also be high. An E.ON Next poll of 2,000+ consumers revealed that more than nine in 10 (93%) UK adults*** want to improve their home energy efficiency and over four in five (83%) think the government should do more to upgrade the energy efficiency of homes.
Ramona Vlasiu, Chief Operating Officer for E.ON Next, commented: “The cost of energy in the UK is too high and as winter approaches, millions of households, especially the most vulnerable, will be anxious about their bills in the months to come.
“Financial support packages such as the Winter Fuel Payment have a role to play in tackling the issue, but we believe the way to solve it long-term is to put people at the heart of the energy transition. That means upgrading their homes with new technology, such as batteries, and putting them in control of the energy they use. Doing so will not only lower energy bills in the short term, but also create a national energy system with a long-lasting positive impact by reducing fuel poverty, creating jobs and boosting the economy.”
Unlocking energy flexibility in homes key to achieving government policy aims
Channelling money into home energy efficiency would signal a shift to the government’s flagship GB Energy initiative, which is backed by £8.3bn of public funds. To date, £2.5bn has been committed to new nuclear power, and over £1bn to strengthen clean energy supply chains. However, E.ON Next believes a more immediate impact on lowering bills and achieving clean power could be realised by unlocking energy flexibility in homes.
Chris Norbury, CEO of E.ON UK, said: “Our national investment in energy infrastructure will, of course, progress decarbonisation and have a positive impact on energy security. Yet the impact of renewable power generation will not happen straight away.
“In parallel, we must therefore unlock flexibility at a household level and treat it as a core national asset. Flexibility helps people to take control of their energy use, lower their bills, and reduce pressure on the network. Putting batteries in residential properties across the country – particularly for people who need the most financial support – should be the start of that journey. Together, we can usher in The Home Age.”
E.ON takes The Home Age to Labour Party Conference
To further its call for energy investment into UK homes, E.ON Next is taking its Home Age campaign to the Labour Party Conference this weekend. A miniature model of its Coventry battery pilot will feature at E.ON Next’s Geodome, with copies of The Home Age report available for MPs, Ministers and delegates to read and take away.
