The fourth part of the demolition of the Thames' last remaining power station will take place later this month.
At approximately midnight on Thursday, June 13, a controlled explotion will bring down part of the "D" station at Littlebrook, Dartford.
The station's de-aeration bay, which is made of steel, will be demolished.
The 10-second explosion will coincide with a short rolling road block on the QE II bridge, to make sure drivers aren't distracted.
An exclusion zone, within the power station boundary fence, will also be put in place before, to protect everyone on site and in the nearby area.
There will be no public access to the area, or any impact on local roads, and the event won't be visible from outside the boundary.
Brown and Mason, who have completed the previous three demolitions, have said the explosion may be heard of site briefly, but it is still classed as a low impact project.
Demolitions of parts of the main structures are set to continue throughout 2019, with the completion expected in 2020.
