Fuse, OVO, Rystad, Jackdaw: this week's top energy stories.

Fuse, OVO, Rystad, Jackdaw: this week's top energy stories. October 24, 2026 This week's top stories include Fuse's plug-in solar and storage system, OVO's executive reshuffle, the UK's approval of the Jackdaw gasfield and more Fuse Energy has made its new plug-in solar and storage system, Jules, available for pre-order, with potential savings for UK households of £330 per year Solar is currently the cheapest source of electricity in the UK, yet fewer than 10% of households across the country currently have solar panels. That is a huge missed opportunity not only for Britons struggling with the cost of energy but for the UK Government, whose ambitious net zero goals depend on nationwide decarbonisation. Fuse Energy, Europe's fastest growing energy company, has a solution that could put solar power in the hands of millions more UK citizens. The London-based firm has today announced that Jules, a first-of-its-kind plug-in solar and battery storage system, is now available for pre-order in the UK. OVO's senior leadership team has been restructured, with ex-E.ON executives Anthony Ainsworth named CEO, Christopher Shead as COO and Richard Brooks as CCO OVO is undergoing a significant executive reshuffle following the completion of its acquisition by E.ON, with three senior appointments signalling a new chapter for the UK energy supplier. Anthony Ainsworth, formerly Chief Operating Officer of E.ON UK's industrial and commercial business, will take over as OVO's CEO. Christopher Shead, previously Director of Customer Operations at E.ON UK, becomes Chief Operating Officer, while former E.ON UK Finance Director Richard Brooks takes on the role of Chief Commercial Officer. Anthony succeeds Chris Houghton, who returned to lead OVO's retail energy business in November 2025 following spells at the company between 2014-2018 and 2020-2021. The appointments follow the Competition and Markets Authority's clearance of E.ON's acquisition on 1 October 2026, with the transaction formally completed a week later. Rystad Energy's Global Energy Scenarios 2026 finds energy security, not just climate policy, now sets the pace of the transition, led by electrification In 2021, Russia supplied around 36% of Europe's gas imports. By 2025, that figure had fallen to around 7.5% as a direct result of Russia's invasion of Ukraine in 2022. Over the same period, Europe's imports of American LNG rose from 6% to around 21%. That shift helps to explain why the global energy system has coped with the Strait of Hormuz crisis better than many feared, according to a new report from Rystad Energy, one of Europe's foremost energy intelligence institutions. Jon Ødegård Hansen, Senior Vice President and Head of Energy Systems at Rystad Energy, says the report was built around the uncertainty that has dominated global energy markets throughout much of the 2020s. "Over the past five years, global energy markets have weathered two severe energy crises," he explains, referencing the Russia-Ukraine war and the US-Israel-Iran war. "Both had long been seen as major risks to the global energy system, yet so far they have played out quite differently than many expected." Shell and Equinor's Adura joint venture wins consent for Jackdaw, as the UK weighs energy security against net zero ambitions after a lengthy legal battle The UK Government has officially approved drilling in the Jackdaw gas field in the North Sea, ending years of legal and political wrangling. Energy Secretary Miatta Fahnbulleh authorised the regulator to grant consent to Adura, the Shell and Equinor joint venture that operates the field, located 150 miles east of the Aberdeenshire coast. Adura expects production of gas to begin within a mere matter of weeks. The Energy Secretary said the decision would support the country's energy security with homegrown gas this winter, though several commentators have argued otherwise. The Conservative government first approved Jackdaw in 2022, but the courts later found that the emissions from burning the gas had to be assessed before production could begin. That Supreme Court ruling in the Finch case sent Jackdaw and the Rosebank oil field back through the regulatory process, which has taken years. Before taking office in the summer of 2024, the Labour government had pledged not to approve new drilling licences in the North Sea, though this decision by the Burnham administration reneges on that initial promise. Since succeeding Sir Keir Starmer this summer, Prime Minister Andy Burnham has repeatedly vowed to take a "pragmatic approach" to decisions over drilling in the North Sea, which has been a cause célèbre amongst environmentalists and energy insiders alike. The UK's onshore wind applications have hit a peak, with RenewableUK welcoming the revival but Caeli warning grid access and site quality decide delivery Developers are lodging plans for onshore wind farms in England at a rate not seen in ten years. About 45 applications were submitted in the year to March 2026, according to an analysis of government data done recently by The Guardian. That is the highest annual total since the Conservatives' de facto ban on new onshore projects took hold in 2015. Labour dropped the restrictions within days of taking power just over two years ago, with former Chancellor Rachel Reeves calling the Tory ban "absurd". Since then, the effect on the planning pipeline has been stark. Before the election in 2024, applications covered about 9MW of onshore wind a month in England, measured on a 12-month rolling average. By the start of this year, that figure had reached about 36MW a month. The low point came before September 2023, when Conservative ministers first began easing planning rules and applications averaged around 1MW a month.

Free electricity? The smart meter schemes paying households to use electricity.

Free electricity? The smart meter schemes paying households to use electricity. July 02, 2026 With the recent OFGEM price cap rise, energy markets remaining volatile and household bills still painfully high, you are probably looking for any realistic way to reduce your energy costs. Now, some households are finding an unexpected solution and getting paid to use electricity. Across the UK, energy suppliers are expanding schemes that offer free electricity, cashback and discounted rates when renewable energy production is high. In some cases, you can effectively be rewarded for running appliances, charging your electric car or heating water during periods when the grid has surplus power. Discover more electricity prices It is one of the few genuinely positive developments in the energy market right now. The shift is being driven by Britain's growing reliance on renewable energy, particularly wind power. When conditions are especially windy, the UK can generate more electricity than consumers actually need. Traditionally, the National Energy System Operator (NESO) would pay wind farms to reduce output to prevent oversupply. Now, suppliers are increasingly trying to solve that problem by encouraging you to use the excess electricity instead. The result is a growing number of "flexibility schemes" designed to reward you for shifting when you use power. How the schemes work. Most energy suppliers already run programmes that notify you when electricity is free or significantly cheaper for a short period. You can then use that window to charge an electric vehicle, run your washing machine, use the dishwasher or heat your water tank. The offers are usually linked to periods of high renewable generation and lower overall demand. Other schemes work slightly differently and reward you for reducing electricity use during busy periods, helping suppliers ease pressure on the grid. In both cases, the principle is the same: if you can use electricity more flexibly, you may be able to reduce your bills. How you can access the schemes. In most cases, you will need a smart meter with half-hourly readings enabled. You should then check whether your supplier offers agile tariffs, EV charging tariffs or flexibility reward programmes. Major suppliers including Octopus Energy, Ovo, EDF and British Gas have all launched versions of these schemes. Discover more Dictionaries & Encyclopedias But you do not necessarily need to switch supplier, or even change tariff to take part. Platforms such as uSwitch now allow you to join certain flexibility programmes regardless of who currently supplies your energy. In some cases, you can connect your smart meter and receive alerts about upcoming energy-saving or cashback events while staying on your existing tariff. That makes these schemes far more accessible than many consumers realise, particularly if you want to test the potential savings without committing to a completely new energy deal. Are there any drawbacks? If you want to maximise the benefits from flexibility schemes, you will usually save more if you can shift larger amounts of electricity use to cheaper periods. That means households with electric vehicles, smart plugs, home batteries or automated heating systems often see the biggest rewards because they can more easily charge devices or run appliances when electricity prices fall. However, buying that technology can be expensive, and you may not save enough immediately to justify major upgrades purely for the schemes themselves. Most flexibility programmes also rely on smart meters and half-hourly usage data. You will usually need to agree to more detailed energy monitoring so suppliers can track when you use electricity and calculate rewards accurately. While suppliers say the data is only used to manage discounts and payments, you may still feel uncomfortable sharing more detailed information about your household energy patterns. Some tariffs also carry more risk than traditional fixed-rate deals. Agile and tracker tariffs can offer extremely cheap electricity during periods of high renewable generation, but prices can also rise sharply when wholesale markets become volatile, particularly during periods of geopolitical tension or energy supply disruption. That means you should understand exactly how the tariff works before moving away from the stability of a fixed-rate deal. There is also a practical consideration, in that, flexibility schemes work best if you can adapt when you use electricity. If your household relies heavily on energy during busy evening periods or you have less flexibility around your daily routine, your savings may be smaller. Why this still matters. Despite the drawbacks, these schemes highlight a major shift in how your energy bills may work in future. As more renewable power is added to the grid, suppliers increasingly need consumers to help balance supply and demand more efficiently. That means electricity pricing is likely to become far more dynamic, with costs changing depending on demand, weather conditions and renewable generation. If you are willing to adapt, that could create genuine opportunities to reduce your bills at a time when many households need savings wherever they can find them, and unlike many recent stories about rising energy costs, this is one area where you may finally be able to turn market volatility to your advantage.

Ofgem orders OVO to pay £10.4m over prepayment-meter failings.

Ofgem orders OVO to pay £10.4m over prepayment-meter failings. UK energy watchdog Ofgem said on Wednesday that OVO Energy has agreed to pay roughly £10.4m in redress after an investigation found that failings in its processes between 2018 and 2024 may have put prepayment-meter customers at risk. Ofgem, which has taken similar action against British Gas, said the settlement included a £7m payment into its voluntary redress fund, alongside £3.4m in customer credits and debt relief in lieu of compensation or formal penalties. "It is clear that OVO fell short in its support of vulnerable PPM customers, and it's right that they've taken action to improve their processes," said Cathryn Scott, director of market oversight and enforcement. Separately, Ovo will pay about £1.1m to customers in Scotland's Highlands and Islands after a review found certain rural households lacked adequate access to engineer support between January 2022 and April 2024.

OVO Energy to pay £10.4m for process failures that "could have put vulnerable customers at risk"

OVO Energy to pay £10.4m for process failures that "could have put vulnerable customers at risk" 3 Jun 2026, 08:26 OVO Energy has agreed to pay about £10.4m ($14m) in settlements after an investigation found failures in its processes that could have put prepayment meter customers at risk. Energy regulator Ofgem said it had closed its investigation into the supplier for its process failures that could have put vulnerable prepayment meter (PPM) customers at risk. The regulator's investigation concluded that OVO's inadequate monitoring of PPM customers, including those on the Priority Services Register (PSR), led to breaches of Ofgem's rules designed to protect customers in vulnerable situations. It said this "exposed consumers to a clear risk of harm". In recognition of Ofgem's findings, Ovo, founded by entrepreneur Stephen Fitzpatrick, has agreed to a settlement package. This includes a £7m payment to Ofgem's Voluntary Redress Fund and providing a £3.4m package of credit and debt relief for some of its most vulnerable customers, in lieu of compensation. Ofgem said customers who are due payments will be contacted by OVO Energy and do not need to take any action. OVO is also in the process of paying £1.1m to customers in the Scottish Highlands and Islands following compliance engagement. This identified that some rural customers did not have appropriate access to engineer support during the period from 1st January 2022 and 1st April 2024. OVO, during the investigation, undertook remedial actions to support vulnerable customers, including welfare visits for customers who had disconnected for more than 72 hours, and not responded to any communication during that peri Cathryn Scott, director of Market Oversight and Enforcement for Ofgem, said: "It is clear that OVO fell short in its support of vulnerable PPM customers, and it's right that they've taken action to improve their processes. As a result of our investigation, vulnerable customers will receive debt write-off or credit payments alongside a payment into our voluntary redress fund. "Prepayment meters are a positive choice for many customers, helping them stay in control of their energy use and reporting high levels of satisfaction - but it's not suitable for everyone and strong monitoring must be in place to protect vulnerable consumers. "This investigation forms part of Ofgem's wider work to raise standards across the energy market and strengthen consumer protections, challenging suppliers to do more to identify and support customers in difficulty. "Anyone worried about paying their bill should contact their supplier as early as possible to access the support available and discuss the options that suit their circumstances." An OVO spokesperson said: "Ofgem's investigation examined how we supported prepayment meter customers between 2018 and 2024. We accept that some of our historic processes fell short of expected standards, and we are sorry for that. "Keeping our customers safe and supported is hugely important to us and we recognise there were areas where we needed to do better. "We have since worked to strengthen our policies and systems, including a new Safe and Reasonably Practicable (SARP) policy, strengthening how we identify and support our vulnerable customers. This settlement reflects both those historic issues and the improvements we have made." The company said that customers who may be eligible for a goodwill payment will be contacted directly by OVO, adding they do not need to take any action in response to this announcement.

Ovo Energy to pay more than £10m over prepayment meter monitoring failings.

Ovo Energy to pay more than £10m over prepayment meter monitoring failings. Regulator finds inadequate monitoring by firm could have exposed vulnerable customers 'to clear risk of harm' Ovo Energy has agreed to pay more than £10m after the energy regulator for Great Britain, Ofgem, found a lack of monitoring of vulnerable customers with prepayment meters (PPMs) could have exposed them to a "clear risk of harm". Ofgem found that Ovo did not adequately monitor its PPM customers, including those on the priority services register, leading to breaches of the watchdog's rules designed to protect customers in vulnerable situations. In response to the findings, Ovo agreed to a settlement package including a £7m payment to Ofgem's voluntary redress fund as well as a £3.4m package of credit and debt relief for some of its most vulnerable customers, which the regulator said was in lieu of compensation. Any Ovo customers due to receive credit or debt write-off payments would be contacted by Ovo and do not need to take any action, Ofgem added. In addition, Ovo - set up by the former Tory donor Stephen Fitzpatrick - is in the process of paying £1.1m to customers in the Scottish Highlands and islands, after compliance work by the regulator found that some rural customers did not have appropriate access to engineer support for more than two years, from 1 January 2022 to 1 April 2024. During Ofgem's investigation into Ovo, the company took some action to support vulnerable customers, including making welfare visits to people who had been disconnected from their energy supply for more than 72 hours and who had not responded to any communications during that time. In some cases, customers who had run out of credit were not contacted by the energy supplier. Ofgem's investigation looked into Ovo's treatment of its existing PPM customers rather than customers having PPMs installed without their consent. "It is clear that Ovo fell short in its support of vulnerable PPM customers, and it's right that they've taken action to improve their processes," said Cathryn Scott, the director of market oversight and enforcement for Ofgem. "Prepayment meters are a positive choice for many customers, helping them stay in control of their energy use and reporting high levels of satisfaction - but it's not suitable for everyone and strong monitoring must be in place to protect vulnerable consumers." Ovo said in a statement that it accepted that some of its historic processes fell short of the expected standards. It added that since 2024 it had significantly improved its policies, systems and training, and how its policies were followed, including implementing a new policy around how it identified and supported vulnerable customers. An Ovo spokesperson said: "Ofgem's investigation examined how we supported prepayment meter customers between 2018 and 2024. We accept that some of our historic processes fell short of expected standards, and we are sorry for that. "Keeping our customers safe and supported is hugely important to us and we recognise there were areas where we needed to do better." Ovo's settlement is the latest blow for the company, which was fined £2.7m in January after failing to pass on government support payments for winter energy bills to thousands of vulnerable customers during the energy cost crisis. The German energy group E.ON said last month it had agreed to buy Ovo in a deal that would create Britain's biggest gas and electricity supplier by number of households served.
