Physical security specifications for power plant security are extremely complex. When setting up its security process, plants must examine several risk factors: risk segmentation, alternative power supply, landscape characteristics, as well as industry-specific equipment requirements.
To decentralize risk, overseeing of the site geography can be segmented in several access control systems run by a number of parallel networks.
It's high-priority to enable an alternative external power supply system and secure it separately to be able to run operations and restore the power plant security even when the main electricity from the plant itself is cut off.
Since power plants are industrial facilities relying on natural resources, access control security for plants needs to support the environment by detecting landscape changes. Safeguarding from aerial threats is an added task, especially having in mind drone attacks.
Well-designed power-plant security plants always need to implement tailor-made solutions for substations or switch yards - they must not be left unattended even if the plant has a 24/7 surveillance system. Sometimes, the better option for substations is to have them incorporated in the overall access control system, On other occasions, they can have an extra standalone access control point. Peripheral security, including isolated high-voltage transmission lines and control towers need adequate risk mitigation strategy for the concrete plant.
