The UK’s National Energy System Operator (ESO) is set to launch a nationwide programme allowing households and businesses to earn money by reducing energy consumption during periods of high demand on the electricity grid.
The scheme, known as the Demand Flexibility Service (DFS), was initially introduced last winter to help manage price spikes during the energy crisis.
From 27 November, the service will be available year-round, enabling participants to support grid stability while cutting their own energy costs.
Under the programme, consumers can reduce their energy use during peak times — typically between 4 pm and 7 pm — in exchange for financial rewards. The initiative aims to ease strain on the grid, particularly during periods of extreme weather, maintenance, or heightened electricity demand.
Consumers wishing to participate will need to sign up through their energy supplier, who will coordinate the process with the grid operator.
During designated DFS events, participants will be alerted to reduce power consumption by turning off non-essential appliances, delaying high-energy tasks like laundry, or using stored energy from batteries or smart devices.
The National Grid ESO estimates that during last winter’s trial, around 1.6 million households signed up, helping save over 3,300 megawatt-hours of electricity — enough to power 10 million homes for an hour.
Building on that success, the expanded programme will allow for greater consumer participation and provide year-round support for the grid.
The Demand Flexibility Service reflects the UK’s push towards modernising its energy system as it transitions to a low-carbon future. It also provides consumers with a proactive way to manage their energy bills amid ongoing concerns about the cost of living and fluctuating energy prices.
By encouraging more efficient use of electricity, the UK programme supports the integration of renewable energy sources, which are often weather-dependent and require balancing mechanisms to ensure grid stability.
Similar demand-response initiatives are already in use in countries like Germany and the US, where they have proven effective in stabilising energy systems while reducing reliance on fossil-fuel-powered backup plants.
In a statement, the National Grid ESO highlighted the programme’s benefits: “This is an important step in ensuring a secure, efficient, and sustainable energy system while giving households and businesses the opportunity to save money and make a tangible impact.”
Consumers interested in the scheme are advised to contact their energy supplier to learn about eligibility and potential savings.
