Substation Physical Security

Physical protection at transmission and distribution substations can be a significant factor in minimizing or deterring various types of threats.

Physical protection at transmission and distribution substations can be a significant factor in minimizing or deterring various types of threats.

Attacks on substations and other critical utility infrastructure are increasing in frequency and have the potential to cost the utility hundreds of thousands of dollars in financial losses, result in damage to equipment, theft of materials or equipment, and/or power outages.

Around-the-clock centralized monitoring and alerts offer early awareness and visibility into problems enabling the utility to respond. Physical security requires a reliable, secure, high-performance communications network between security devices (sensors, cameras, key pads, lights, etc.) and computers located in the utility’s operations center.

Adding network communications to existing substations to extend reach to the various security devices around the yard is often physically or financially prohibitive. As wireless networks require no trenching, they are typically the most cost-effective solution for existing substations. Some of the physical security applications commonly used are video surveillance cameras; access control using biometrics, keypads, etc.; perimeter sensors that detect thermal/motion; and gunshot detection, alerting and location identification.

Substation physical security benefits for utilities include:

Deters malicious activity

Serving as evidence for prosecuting perpetrators.

Reduces potential safety risks and damage

From the malicious activity, vandalism, and theft with an early alert of unauthorized substation access, which could result in physical or cybersecurity damages.

Logging of authorized personnel

 Entering and exiting the facility provides accountability and can improve worker safety.    

Reduces truck rolls

Enhancing situation awareness and increases operational efficiency and worker safety with the ability to monitor the physical protection of substations remotely.

Reliable and resilient communications

Lying as the foundation for NERC CIP-014-1

Hitachi Energy offers high-performance broadband, narrowband and cellular solutions that can work together to provide utilities with an optimal end-to-end communications network that enables a wide range of smart grid applications and a foundation for critical infrastructure protection.
