Octopus Energy customers have been able to get money back on their bills by taking part in the supplier's "saving sessions".
The sessions are a part of the National Grid ESO's new 'Demand Flexibility Service' and has seen the top five percent of savers earned almost £20 across Octopus' test sessions so far
They have implemented a saving session five times now, and with 250,000 customers already signed on, they have paid out over £1 million in total.
Alex Schoch, Head of Flexibility at Octopus Energy Group, commented: "This is a massive milestone - across just four hours, we’ve been able to pay out £1 million to our customers.
"Normally, this money would have gone to businesses or dirty gas power plants to balance energy demand, instead it’s helping people lower their energy bills this winter.
"We are proud to have pioneered this trailblazing scheme, which is paving the way towards a smarter, greener and cheaper grid for all.
"And we’re glad that other energy suppliers are now getting involved, allowing even more people to grab a bargain and lower bills for everyone."
Octopus customers lowered the energy demand on the grid during each of these peak periods by over 100MW - the same amount as a gas power station can produce in an hour.
Customers saved on average over £4 across the first four sessions, with the top five percent of savers bringing in almost £20.
Customers were paid in the form of 'Octopoints', which can be exchanged for energy account credit, cash or eventually prizes and donations.
