Explosives will be used to topple the 236m (778ft) tall chimney at the former Inverkip Power Station near Greenock in Inverclyde.
The chimney contains more than 1.4 million bricks and 20,000 tonnes of concrete, and is almost as high as Arthur’s Seat in Edinburgh.
The operation will take place at 22:00 on Sunday.
The chimney will be toppled by two controlled explosions taking place in quick succession.
About 70 police officers, as well as a force helicopter and boat, will attend the demolition.
A further 40 security staff will be in position around the perimeter.
Exclusion zoneAn exclusion zone of 600m will be put in place from 17:00, with debris expected to reach a maximum of 150m.
After the demolition, Scotland’s tallest free-standing structure will be the chimney at Longannet Power Station, which is 183m (600ft)tall.
The Inverkip operation will mark the end of a power station which was never able to fully operate as intended.
The oil-fired facility was given planning permission in 1970, and was designed to meet peak demand and provide flexibility to the electricity supply network.
However, the soaring price of oil in the 1970s meant the station was never commercially operated – except in 1984 and 1985, as a result of coal shortages.
The plant was kept as a strategic reserve until the late 1990s, when it was mothballed.
