People could be paid for turning off high-energy appliances during peak times this winter.
Those with smart metres could get up to £6 per kilowatt hour (kWh) saved as energy prices rise with strained supply and the expectation the National Grid could come under pressure.
The National Grid Electricity System Operator (ESO) is understood to be working on an announcement for the plan.
Rebates for not using appliances like tumble dryers, dishwashers and electronics between 5om and 8pm would net customers a return.
One kWh is enough energy to power a dishwasher for less than an hour, or use an electric shower for six minutes.
A tumble dryer uses roughly 4.5 kWh per cycle, according to estimates.
The plans were first reported in The Sunday Times, with the grid set to apply to regulator Ofgem for approval.

The ESO hopes the scheme could be up and running by October.
A spokesperson told Sky News: “We are developing a new service that will be available for consumers to benefit from across this winter and will be announcing further information soon.”
It comes following a trial with Octopus Energy earlier this year, where customers were paid as little as 20p per kWh saved.
A range of prices – up to £6 – has been considered for the new scheme.

It comes as the energy price cap is forecasted to rise to roughly £3,600 before the end of 2022, and past £4,200 in the new year.
Ofgem will announce the change to the cap for October and December on Friday.
Chancellor Nadhim Zahawi last week suggested that rolling blackouts are unlikely as preparations were under way for the winter.
