The UK electricity system has gone one whole week without any output coming from coal-powered generation.
This is the first time the country has gone so long without coal contributing to the generation mix, said National Grid ESO.
It said the last coal generator came off the system at 13.24 on 1 May.
Electricity has been produced over the last seven days by a mix of natural gas, nuclear, renewables and imports.
Business and Energy Secretary Greg Clark said: “Going a week without coal for the first time since the Industrial Revolution is a huge leap forward in our world-leading efforts to reduce emissions, but we’re not stopping there.
“To combat climate change and seize on the opportunities of clean growth, we’re phasing out coal entirely by 2025 and building a cleaner, greener energy system.
“We lead the world when it comes to tackling climate change and we want to carry on breaking records, which is why we’ve put foundations in place to allow our renewables sector to thrive.
“We’re now on a path to become the first major economy to legislate for net zero emissions.”
National Grid ESO director Fintan Slye said: “While this is the first time this has happened, I predict it will become the ‘new normal’.
“As more and more renewables come onto our energy system, coal-free runs like this are going to be a regular occurrence.
“We believe that by 2025 we will be able to fully operate Great Britain’s electricity system with zero carbon.
“To reach zero carbon operation by 2025, we will continue to identify the systems, services and products we will require to run a zero-carbon network and design the new competitive marketplaces needed to source these as efficiently as possible from both new and existing companies.
“We believe that promoting competition will ultimately lead to better value for consumers. The new products and services we will introduce will help reduce the overall cost of operating the system, driving down costs for consumers.
“Operating a zero carbon electricity system in 2025, whenever there is sufficient renewable generation, is a major stepping stone to full decarbonisation of the entire electricity system.
“This will enable new technologies and removes barriers to ever increasing levels of renewables.”
Greenpeace UK chief scientist Doug Parr said: “Just a few years ago we were told Britain couldn’t possibly keep the lights on without burning coal.
“Now coal is quickly becoming an irrelevance, much to the benefit of our climate and air quality, and we barely notice it.”
