What is the meaning of 'Security Assessment'?

The term 'Security Assessment' is best defined as an evaluation of potential risks to the reliability of the electric grid. This process involves identifying vulnerabilities and threats that could impact the grid's operational integrity, including cyber threats, physical security issues, and other factors that could compromise reliability. A security assessment systematically examines these risks to help develop strategies and plans for mitigating them, ensuring the continuous and reliable operation of the electricity supply.

In the context of the electric grid, maintaining reliability is essential for operational stability and safety. Therefore, conducting a comprehensive evaluation of these risks is a critical step in securing the infrastructure against disruptions. This assessment informs decision-makers on necessary improvements and resource allocations to bolster grid security.

The other options, while relevant to the overall energy landscape, do not address the specific scope of what constitutes a 'Security Assessment' in the context of the reliability of the electric grid. They pertain to different aspects of utility operations or historical performance analysis, which are important but do not directly relate to the evaluation of security risks.
