Three boiler houses are to be blown up in the next stage of decommissioning of the Grain power station.

Energy giant E.ON announced this week that the 55m building will be detonated on Sunday, August 2 at 8am.

The houses contain three of the five oil-fired boilers which were once integral to generating electricity at the plant, on the Isle of Grain.

Before closure, the plant produced enough electricity to power more than one million homes.

During the explosion about 20,000 tonnes of steel will be brought to the ground, which will be one of three demolition milestones at the site before the 244 metre chimney comes down at some point next year.

Mike Cooper, head of demolition at E.ON said: “This demolition will be quite significant in scale due to the size of the buildings involved, so we’re informing the local community in advance of the controlled explosion and working with the local police and council to ensure there’s minimal disruption.”

In May, three other buildings were pulled down which were also part of the boiler structure.

The demolition process on the Isle of Grain began on the oil-fired power station in April 2014, following its closure in December 2012.
