ONE of the workers who built the UK’s tallest industrial chimney at a North Yorkshire power station has returned to the site to mark its anniversary – half a century on from the structure being completed.

Harry Shann, now 83, was part of the team who worked at Drax Power Station 50 years ago constructing the 850ft high chimney, which has three flues linked to the site’s six generating units, four of which now run on sustainable biomass instead of coal.

The chimney took just four months to build after work started in early 1969 and was completed four months ahead of schedule by a team of around 30 workers, with the topping out ceremony held in May to celebrate its completion.

Now, Harry, who was just 33 when he joined the project and still lives locally in Selby, has spent time back at the Drax site to reflect on his involvement in the record-breaking construction project.

He said: “I still see it pretty much every day. It was definitely the highest build I ever worked on.

“I’m very proud of it, even after all these years, and I can still remember the time I spent on site. Considering the size of it though, we weren’t there long. We really got a move on.”

Due to the height of the structure, reaching the top can only be achieved by an eight-minute journey in an industrial lift or by scaling the 1,460 steps spiralling up the central void of the chimney.

Views from the top can stretch as far as the Humber Bridge more than 30 miles away on a clear day – and Harry admits it was only a job for those who were comfortable working high above the ground.

Mr Shann said: “I just never had a fear of heights. I was in the Parachute Regiment before I became a scaffolder, so that might have had something to do with it,” the octogenarian said on his return visit to view the huge structure he helped to create.

“Being back at Drax Power Station, I realise just how much it’s changed. When I worked here, looking down from the chimney the area was bare, with hardly any buildings. Now it’s just amazing, it’s a wonderful site and I feel proud that the chimney is still standing 50 years later.”

The North Yorkshire power station, which first began generating electricity in 1974 when the first of its six generating units was commissioned, now produces enough electricity to supply five per cent of the UK’s power and is the biggest decarbonisation project in Europe.

Drax Power CEO Andy Koss said: “Harry’s efforts, along with his colleagues’, in building such an important and iconic part of the power station are an integral part of Drax’s history and ongoing success.

“50 years on it is still the tallest industrial chimney in the UK – in many ways its completion marked the start of a rich heritage for engineering excellence and innovation at Drax, which has continued to the present day.”

Earlier this year, Drax confirmed that its ground-breaking trial of bioenergy carbon capture and storage (BECCS), using technology developed by Leeds-based C-Capture, had become the first project of its kind in the world to capture CO2 from a 100% biomass feedstock.

Drax has converted two-thirds of its generating units at the site near Selby to use sustainable biomass instead of coal transforming the business to become the largest renewable power generator in the UK.
