Households could get free electricity for doing washing on sunny weekends

Households and Businesses May Benefit from Free or Discounted Electricity During Surplus Supply

The National Energy System Operator (NESO) has launched a revised Demand Flexibility Service, allowing households and businesses to access reduced-cost or complimentary electricity from their providers during periods of excess energy generation. This update, approved by the industry regulator Ofgem in March, aims to optimize energy usage and prevent waste during times when supply exceeds demand.

Previously, energy companies incentivized customers to shift electricity consumption to off-peak hours with lower rates. Now, the new framework encourages users to increase energy use when “weather conditions result in excess supply,” as noted by NESO. This shift is designed to enhance the system’s resilience during the summer months, when demand typically dips and solar generation rises.

Summer energy demand decreases due to warmer weather and longer days, while solar power output grows. NESO highlighted that weather patterns are increasingly shaping low-demand periods, and the expansion of smaller, local generators is further reducing dependence on large-scale power stations. These factors are making surplus electricity more frequent, prompting the need for updated strategies.

The revised program rewards customers for using appliances like washing machines, dishwashers, and electric vehicles during times of high renewable energy production and low demand, such as weekends or public holidays. Participation requires smart meters, and energy providers will determine the nature of incentives, which could include free electricity, discounted rates, or points redeemable for gift cards.

Currently, companies such as British Gas, Equiwatt, and Octopus Energy have joined the initiative. NESO emphasized that managing the system during low demand has become more complex, stating:

“The complexity of operating the system at low demand is increasing, and we may need to use more of our tools, and use them more often, than in previous summers.”

This could involve issuing notices to power stations to adjust output for safety during periods of surplus energy.
