The UK has just completed its first week without any domestic coal generation on the power grid since before the Industrial Revolution, marking a significant milestone in its low-carbon energy transition.
It is well known that coal is becoming less and less important in Great Britain's electricity mix, now accounting for under 10% of the country's power output, and on track for the Government's planned phase-out by 2025.
The landmark was reached two years after Britain had its first coal-free day since the Industrial Revolution.
"As more and more renewables come on to our energy system, coal-free runs like this are going to be a regular occurrence", the director said.
Britain took a break from coal power. Last month, the electricity grid operated for nearly 92 hours with no domestically generated coal-fired power, far exceeding the previous record of 76 hours, which was set between 21 and 24 April 2018. On Wednesday Britain did one better: The island nation went a full week without using coal power.
A GW of power will provide enough energy for about 700,000 homes.
National Grid director Fintan Slye said he believed even longer records would soon be set. "Now coal is quickly becoming an irrelevance, much to the benefit of our climate and air quality, and we barely notice it".
The week without coal is a new record for Britain, topping a 90-hour run earlier this year. "More people have installed solar, more coal is coming off and there's more wind in the system".
In 2015, the United Kingdom pledged to remove coal from its grid by 2025.
"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".
The National Grid spokesman said that although Britain has experienced a cold snap following an unseasonably warm Easter, there has been no obvious surge in demand to suggest the public have been turning the heating back on.
A spokesman for the National Grid added: "As more and more renewables come onto our energy system weekends like this are going to increasingly seem like the 'new normal".
"We believe that, by 2025, we will be able to fully operate Great Britain's electricity system with zero-carbon".
