About NAESC
NexGen Advanced Energy & Substation Consultants (NAESC) is a premier engineering consultancy specialising in high-voltage infrastructure, substation design, and advanced power systems engineering. A pure design office — no contracting, no supply — we provide civil, mechanical, electrical, and protection & control design for substations, cable systems, and power infrastructure, from feasibility through Issued-for-Construction (IFC) documentation, supporting EPC contractors and utility partners across the GCC, Europe, and Africa. We deliver the technical precision and innovative solutions required to secure, optimise, and future-proof the power grid.
To deliver precision-engineered design that powers reliable, safe, and efficient infrastructure.
To be the most trusted name in high-voltage design consultancy across every region we serve.
We do one thing: engineering design. Substations, OHTL, UGC, power studies, BIM, BESS, and Solar PV — all under one specialist roof. No scope creep, no diluted expertise.
Technical Excellence
Every calculation is traceable, every drawing is contractor-ready. We don't submit deliverables until they meet our internal peer-review standard.
Client Partnership
We work alongside client teams, not just for them. Transparent communication, milestone-based progress, and fast RFI responses are non-negotiable on every project.
Standards Compliance
IEC, IEEE, SEC, European standards, and regional grid codes are built into our workflows — not bolted on at the end. Compliance is a design input, not a checklist.
Continuous Learning
NAESC maintains a culture of continuous learning, ensuring the design team stays current with evolving standards, technologies, and best practices across all disciplines.
