The fifth controlled explosion at disused Tilbury Power Station is less than a week away.

The next blast will take place at the Essex site, just across the River Thames from Gravesend, at 3pm next Thursday.

The explosive demolition will simultaneously bring down the northern end of the de-aeration bay and the conditioning and storage bunker.

The de-aeration bay is about 117m long, 17m wide and 44m high and made from structural steel. The concrete conditioning and storage bunker is roughly 40m long, 28m high and 14m wide.

Last month a fourth explosion brought down the southern end of the remaining turbine hall, which was about 112m long, 27m wide and 25m high.

Three of four steel structures known as precipitators were destroyed in a small explosion in June, half the turbine hall was demolished in April and a large explosion in September brought down one of the 28m-high coal junction towers.

The other main structures such as the conveyor system, chimneys and precipitators are scheduled for explosive demolition over the next couple of months.

The boiler house and coal bunkers are scheduled for demolition next year.
