The process for assessing threats and risks to transmission stations is applicable in any environment where people and/or assets may be at risk from a security-related incident or event that could result in human death, injury, or loss of an asset.

The goal of this project is to provide utilities with a template that may be used in its entirety or in part to conduct Threat Risk Assessments (TRA) on sites of varying size and complexity.

Zone managers, familiar with issues associated with safety and asset loss control, are uniquely qualified to comment on and participate in the performance of the TRA. They will review the condition and effectiveness of existing substation security equipment and changes in local threat and risk levels. With the aid of a guiding template, these scheduled zone manager reviews also provide corporate security practitioners with well structured threat and risk assessments without the need for them to travel to sites under review, many of which are in remote locations.

A comprehensive template is provided for use by utility security practitioners or on-site personnel (e.g., zone managers) in identifying areas of ulnerability, including but not limited to the following:

  • Physical security survey methodology
  • Access control badges
  • Barriers
  • Entrances to critical asset areas
  • Surfaces surrounding critical asset areas
  • Fences surrounding critical asset areas
  • Vehicle gates through critical asset area fences
  • Locks, keys, and access cards
  • Intrusion detection systems
  • Protective force
  • Law enforcement agencies (threat environment)

The Threat Risk Assessment model will assist utility security personnel in the preparation of sitespecific reports evaluating the threat environment and providing mitigating recommendations, if required.
