Detecting Substation Intrusion Attempts Through Routine Walkdowns

The Challenge

During a routine walk-around inspection of substation equipment, a TCR discovered that the interior fence of the substation had been cut. Further inspection revealed multiple compromised sections, indicating an attempted unauthorized entry. Such a breach posed serious risks, including:
  • Theft or vandalism of critical infrastructure
  • Potential electrocution or injury to trespassers
  • Service disruption, liability, and reputational harm
  • Violation of utility security compliance standards
This discovery highlights the evolving nature of substation threats—not just operational, but physical security threats requiring routine vigilance.

The Solution

  • The damage was documented and immediately reported to the appropriate utility security and operations teams.
  • A site-wide inspection was conducted to ensure no additional access points were compromised.
  • The compromised fence sections were scheduled for prompt repair and reinforcement.
  • The event served as a catalyst to reiterate the importance of walkdowns not just for equipment, but for security perimeter checks.

Key Benefits

  • Early detection of a potentially dangerous and costly security breach
  • Prevented further unauthorized access, theft, or public exposure to energized equipment
  • Reinforced the role of TCRs in maintaining not just operational oversight, but physical asset protection
  • Triggered discussions around substation hardening and improved fencing materials or surveillance

The Results

  • No equipment loss or injuries occurred, thanks to proactive observation
  • The substation was secured and monitored, with follow-up inspections scheduled
  • The event is now cited as a reminder that job sites don’t always stay as you left them, especially in remote or unsecured locations
