From the northernmost reaches of the River Soar in Nottinghamshire, the towers of Britain’s last coal-fired power station emerge from the flat countryside like concrete monuments to another time.

For more than half a century Ratcliffe-on-Soar has burned millions of tonnes of coal to generate the electricity needed to power the British economy. But one by one Britain’s coal power stations have closed, leaving Ratcliffe the sole survivor. In less than six months it, too, will finally power down for good, extinguishing the last embers of the once-mighty coal industry.

With its last winter behind it, the sprawling site, which covers the same acreage as the City of London, is quiet save for the hum of a single turbine and the crackle of electricity power lines overhead.

It once employed up to 3,000 people, but now a total of about 350 engineers are working there, in shifts, as Ratcliffe ekes out its final months, unsure of how many hours the site has left to run before it closes around the end of September.
