Power-Safe Perimeters: GRP Fencing Secures the Future at Alyth Substation
High-voltage environments require fencing that does more than just mark a boundary. It must protect personnel, resist harsh conditions, and support future infrastructure upgrades. That’s exactly what Engineered Composites delivered for SSEN Transmission’s £86 million Alyth substation project with their GRP palisade fencing system.
A critical part of the UK’s East Coast transmission reinforcement, the Alyth site demanded a fencing solution that balanced safety, strength, and scalability.
The Challenge: High Voltage, Harsh Conditions & Expansion-Ready Design
- Electrical Safety: Fencing had to be completely non-conductive and compliant with substation safety regulations.
- Durability: The system needed to withstand constant exposure to extreme weather, salt, and UV.
- Expansion Compatibility: With planned voltage upgrades from 275kV to 400kV, the fencing needed to be future-ready.
- Low Maintenance: Utility operators required a solution with minimal ongoing upkeep.
GRP Palisade Fencing: Strong, Safe & Scalable
Engineered Composites delivered a full GRP fencing package configured for SSEN’s needs, including secure perimeter pales, mounting systems, and anti-tamper fixings.
Key features:
- Non-Conductive: Ideal for electrical substations, reducing arc risk.
- Weather & UV Resistant: Resists rust, salt spray, and prolonged sun exposure.
- Secure Anti-Climb Design: Sharp-top pales deter intrusion.
- Lightweight for Rapid Install: Easier to transport and assemble without heavy equipment.
- Custom-Fabricated: Fence height, profile, and layout tailored to the substation footprint.
Infrastructure You Can Rely On
Rated for wind loads up to 120 km/h and temperature fluctuations from -40°C to +120°C, the GRP system is built to perform under pressure. With a long lifespan and ASTM E84 Class 2 fire rating, this is true future-proofing for power networks.
Conclusion
SSEN Transmission’s choice of Engineered Composites’ GRP fencing at Alyth substation sets a new standard in safe, scalable perimeter protection. It’s a clear demonstration of how modern energy infrastructure demands modern materials.
