Our Expertise & Service Portfolio
Feasibility Studies & Power System Assessment
Our feasibility services enable confident decision-making by evaluating technical, operational, financial, and regulatory considerations at the earliest stages of a project.
Technical Feasibility Includes:
- Load flow and power evacuation capability analysis
- Equipment rating adequacy and upgrade assessment
- Grid code alignment and interconnection studies
Operational Feasibility Includes:
- Demand growth forecasting and capacity analysis
- System reliability, redundancy, and N-1 / N-2 compliance checks
- Maintainability, outage planning, and operational risk assessment
These studies establish project viability, reduce downstream risk, and support informed investment decisions.
High-Voltage & Medium-Voltage Substation Design
CatalystNex provides comprehensive engineering design for new-build, refurbishment, and extension of AIS and GIS substations.
Our design capability includes:
- Complete substation layouts and general arrangement engineering
- Primary and secondary system design
- Protection and control schematics
- XLPE cable engineering for power and control systems
- Integration of instrument transformers, LV panels, busbar systems, and auxiliary equipment
All designs prioritise safety, operability, maintainability, and regulatory compliance while ensuring seamless interaction across HV, MV, and LV networks.
Civil, Structural & Auxiliary System Engineering
Reliable substations require robust supporting infrastructure. We deliver coordinated civil, structural, and auxiliary system engineering, including:
- Foundation and equipment support design
- Control building layouts, trenches, and ducting systems
- Cable trench, culvert, and auxiliary infrastructure routing
- Earthing and lightning protection systems to BS and IEC standards
- Environmental Impact Assessments (EIA) and regulatory documentation
- Fire protection, lighting, and auxiliary services integration
This integrated approach ensures long-term safety, structural integrity, and environmental compliance.
