The UK went a full day without using coal to generate electricity for the first time since the Industrial Revolution, according to the National Grid.
The energy provider said Friday's lack of coal usage was a "watershed" moment, the BBC reported.
Britain's longest continuous energy period without coal until now was 19 hours – first achieved last May, and again on Thursday.
The government plans to phase out Britain's last plants by 2025 in order to cut carbon emissions.
Friday is thought to be the first time the nation has not used coal to generate electricity since the world's first centralised public coal-fired generator opened in 1882, at Holborn Viaduct in London.
Cordi O'Hara of the National Grid said: "To have the first working day without coal since the start of the industrial revolution is a watershed moment in how our energy system is changing."
"The UK benefits from highly diverse and flexible sources of electricity. Our energy mix continues to change and National Grid adapts system operation to embrace these changes," the BBC quoted O'Hara as saying on Friday.
According to the National Grid, around half of British energy on Friday came from natural gas, with about a quarter coming from nuclear plants.
Wind, biomass, and imported energy were also used.
The last deep coal mine in the UK, Kellingley Colliery in North Yorkshire, closed in December 2015, bringing to an end centuries of deep coal mining in Britain.
