Substation Security Guards protect high-risk electrical infrastructure by securing perimeters, monitoring surveillance feeds, detecting intrusions, and enforcing safety rules. They coordinate with utility operators, document incidents, and ensure compliance with national energy security protocols. The role requires strong situational awareness, physical readiness, and understanding of electrical facility hazards. Growing dependence on electrical grids, expansion of renewable energy sites, and heightened security risks make substation protection a steadily growing area of employment worldwide.
