Primary substation design to 132 kV
Complete primary and secondary design for an HV substation, taken from single line diagram to full layout with clearances and cable routes, delivered to NGTS and British Standards.
The challenge
The client needed a complete, standards-compliant substation design package: one that would pass network operator review without cycles of comment and resubmission, and that a contractor could construct without design gaps appearing on site.
Context
A UK utility substation project at 132 kV, covering both primary plant arrangement and the secondary systems that support it. Client and site details are withheld for confidentiality.
Our scope
Primary and secondary substation design from single line diagram through to full substation layout, including electrical clearance assessments and cable route design.
Technical complexity
Substation design at 132 kV leaves little tolerance for error: statutory clearances, busbar arrangements, cable routes and civil interfaces all interact, and every decision must be traceable to NGTS and British Standards requirements.
Engineering approach
The design was developed as one coordinated package rather than a sequence of independent drawings. Clearance assessments were carried out against the layout as it developed, not retrofitted at the end, and cable routes were engineered alongside the plant arrangement so that neither compromised the other. Every deliverable passed through documented checking before issue.
Key deliverables
- Single line diagrams
- Full substation layout and arrangement drawings
- Electrical clearance assessments to NGTS and British Standards
- Cable route design
Result
A complete, coordinated design package produced to NGTS and British Standards, giving the client a substation design that could be reviewed, approved and taken into construction as issued.
