The £10m Settlement and Regulatory BreachesOvo Energy has agreed to pay more than £10m to the energy regulator Ofgem after investigations revealed a systemic failure to monitor vulnerable customers using prepayment meters (PPMs). The watchdog found that the lack of oversight could have exposed these customers to a "clear risk of harm," particularly those registered on the priority services list.£7m payment to Ofgem’s voluntary redress fund.£3.4m package of credit and debt relief for vulnerable customers.£1.1m payment to Scottish Highlands and islands customers for lack of engineer support.Financial Penalties and Operational CostsThe settlement highlights a significant financial burden on Ovo, compounded by a previous £2.7m fine in January for failing to pass on government winter energy bill support. The regulator identified that some customers in the Scottish Highlands faced a lack of appropriate engineer support for over two years (from 1 January 2022 to 1 April 2024), further exacerbating the company's compliance issues.Regulatory Scrutiny on Vulnerable Customer ProtectionOfgem’s investigation, which covered the period from 2018 to 2024, focused on Ovo’s treatment of existing PPM customers rather than installation practices. Director of Market Oversight Cathryn Scott emphasized that while PPMs are a positive choice for many, strong monitoring is essential to protect vulnerable consumers. Ovo has since implemented new policies and training to address these gaps, though the regulator noted that historic processes fell short of expected standards.Future Outlook: Acquisition and ComplianceThis regulatory setback comes at a critical juncture for Ovo, as the German energy group E.ON has agreed to acquire the company. The deal aims to create Britain's biggest gas and electricity supplier by household count. However, the repeated fines suggest that Ovo faces a challenging path toward regulatory compliance and customer trust restoration under new ownership.

Great Britain is on the verge of a record‑breaking summer of wind and solar generation, creating the possibility of the first zero‑carbon electricity periods in the nation’s power system.The government’s ambition to achieve a 95% gas‑free grid by 2030 underpins this push, as electrified transport, heat pumps and low‑carbon industry will need a clean power supply to meet climate targets.National Grid ESO (Neso) forecasts that on sunny weekend afternoons the grid could have more renewable power than demand, leaving excess capacity that would otherwise be wasted.To turn surplus into savings, Neso is urging households and businesses to shift flexible loads—such as charging electric vehicles, running dishwashers or doing laundry—to those high‑renewable windows.Leading suppliers Octopus Energy and British Gas have confirmed participation, offering special tariffs that reward consumers for using electricity when it is abundant.British Gas’s “PeakSave” scheme, for example, provides half‑price electricity from 11 am to 4 pm on Sundays, with an even cheaper “Super Sunday” option from 9 am to 5 pm. The company says the tariff has saved over £45 million for more than 1 million customers since its 2023 launch. Octopus Energy reports helping 2 million households save about £11 million, including £3 million in free electricity during periods of high renewable output.Other providers—including Ovo Energy and EDF Energy—offer similar “time‑of‑use” tariffs that charge higher rates when renewables are scarce, giving price‑sensitive users a clear incentive to shift consumption.Beyond bill reductions, flexible demand curtails the need for “constraint payments” to wind and solar farms—payments that reached almost £1.5 billion last year. By encouraging consumers to “turn up” rather than forcing generators to “turn down,” the grid can avoid these costly curtailments.Businesses are also joining the flexibility movement. Tech firms report that adaptable energy use can cut datacenter grid costs by up to 5% and slash emissions by as much as 40%. Danish engineering group Danfoss estimates that if datacentres operated flexibly for just 1% of the time, the pipeline of new facilities expected by 2035 could be accommodated without overloading the grid.In short, leveraging surplus renewable power now—through smart tariffs and demand‑shifting—offers a cheaper, faster alternative to massive storage or grid‑upgrade projects, while delivering tangible savings for consumers and a decisive step toward a low‑carbon British electricity system.
