Watch the moment an 801ft tall power station chimney turns into rubble after demolition

Updated: 

The skyline in part of Kent has been altered forever after the tallest concrete structure to be demolished in the UK was blown up.

Experts detonated the 801ft (244m) chimney of the defunct Grain A Power Station on Wednesday, creating some 40,000 tonnes of concrete rubble and stacks of dust and smoke.

Taller than 55 double-decker buses stacked on top of each other and more than double the height of Big Ben, the structure has been a prominent feature of the Medway skyline for more than 30 years.

In a split second, the final controlled demolition marked the end of an era for the many people who worked at the sprawling plant or who live in the local area.

Bill Cliff, plant manager at Uniper's Grain B Power Station, said: "I'm sure the demolition of the chimney will be an emotional day for the people who have worked at Grain A Power Station, and for those that have become fond of seeing the chimney as a prominent feature on the Medway skyline."

Originally opened in 1979, Grain A was able to produce enough electricity to power more than one million homes. It closed in December 2012.

The demolition project began in April 2014 and so far there have been five demolition events to bring down the main infrastructure of the plant.

Since the project began, more than 84,000 tonnes of material has been removed from the site to be recycled, and work is due to continue until the end of the year.

The existing infrastructure at Grain A has been used to build a 1,275MW gas-fired power station on the same site. The development of Grain B means the site can continue to provide electricity to homes and firms.
