Octopus Energy Expands Free Electricity as Grid Surplus Grows
Octopus Energy is expanding its free electricity scheme as britain's grid increasingly faces periods when renewable output exceeds demand. For households with smart meters, the change could mean cheaper power at specific times when wind and solar generation are high.
£1.5 billion on wind cutbacks
£1.5 billion was spent last year compensating wind farms to switch off turbines when the grid could not absorb excess electricity generation, a bill that shows how much renewable power still goes unused. Octopus Energy said the initiative is meant to reduce wasted renewable energy while helping households lower electricity costs at certain times of the day.
£4.6 million in customer savings has already come from earlier free electricity sessions run under Octopus's Saving Sessions programme. The company has also distributed £5.8 million in rewards to households that reduced energy consumption during periods of high demand, giving it a track record to point to as it widens the offer.
Demand Flexibility Scheme changes
Octopus Energy said the expansion follows changes to the National Energy System Operator's Demand Flexibility Scheme. Under the revised system, suppliers can encourage customers to charge electric vehicles, run appliances or increase power consumption during periods when renewable energy supply is particularly high.
"The changes made to the DFS scheme mean customers can benefit from using more energy when renewables are high." — Octopus spokesman. Households with smart meters may be offered free or discounted electricity during those periods, while some suppliers also provide rewards points or vouchers.
What customers can do now
For customers, the practical step is to watch for offers tied to periods of high renewable output and use those windows to run appliances or charge devices if they are enrolled in a qualifying scheme. The structure is built around shifting demand, not increasing total consumption, so the payoff comes from timing rather than volume.
For the grid, the friction point remains clear: Britain still pays to curtail wind generation when supply outstrips demand, even as suppliers are being pushed to turn that surplus into a discount for households. If the revised scheme gains traction, the figures suggest more of the system's excess renewable power could be redirected to homes instead of being switched off.
