Energy giant Octopus has launched the world's first electricity tariff that gets cheaper when it's windy.
The gas and electricity provider said it has invested in two new wind turbines which will bring cheaper greener power to local communities, powering homes for up to 80% of the day.
Octopus, which has 1.8million UK customers, has bought the turbines in Caerphilly, South Wales, and Market Weighton, Yorkshire.
Each turbine can generate up to 500 kilowatts (kW), enough to power up to 400 homes per year each.
From January 2021, local communities will benefit directly from their locally-sourced green power.
The Octopus Energy 'Fan Club' tariff will offer households living near the turbines bespoke 100% green electricity tariffs.
Octopus Energy customers who use electricity when the turbines are spinning, which is roughly 98% of the time, will profit from a 20% discount on the unit price.
When the wind picks up and the turbines are producing even more green electricity, the unit price will see a price cut of 50%.
Compared to the price cap, currently set at £1,042 for a typical dual-fuel household, Octopus Energy 'Fan Club' customers can save up to £229 off their bills while using this revolutionary new tariff.
Zoisa Walton, at Octopus Energy Generation, said: "Octopus Energy's first ever own brand turbines are now on the grid, and we’ve included the UK’s first windy tariff to boot - we halve the price of your electricity whenever your turbine is spinning fast.
"By matching this generation with our proprietary agile technology, we're unlocking exciting opportunities for the cheapest electrons to be the greenest. Soon local customers will be able to join the 'Fan Club' and get discount prices for windy days, helping out their pockets and the planet."
