Standby generator building, RAF Daws Hill bunker compound

The standby generator building at RAF Daws Hill bunker compound is an emergency power plant likely built in the 1980s. It is a partly-buried reinforced concrete structure, with the rear wall and the walls of smaller rooms reinforced internally with steel plates for enhanced protection against nuclear explosions.

Access is from the north through two pairs of double steel doors, which were wide enough for the installation of the plant's diesel generators, now removed. To the east, there are separate rooms that housed the plant's switchgear, which remains intact. Above these rooms are two vents that may serve as an air inlet and exhaust outlet. The building does not include any decontamination facilities. According to the Planning (Listed Buildings and Conservation Areas) Act 1990, the surviving plant and switchgear, which are of standard specification for the period, are not considered to have special architectural or historic interest.
