Substation Design

There are quite a few considerations in substation design. The first consideration is layout design. The most important in layout design is bus bar schemes.

The commonly used bus bar schemes at Sub Stations are:
a) Single bus bar.
b) Main and Auxiliary bus bar.
c) Double bus bar.
d) Double Main and Auxiliary bus bar
e) One and a half breaker scheme

Next is the Earth Mat Design. Provision of adequate earthing system in a Sub Station is extremely important for the safety of the operating personnel as well as for proper system operation and performance of the protective devices.

Supreme undertakes power projects from ideas to successful commercial operation with full coverage of expertise in electricity transmission & Distribution (T&D) either on EPC basis or discrete services like Consultancy on Design & Engineering Services.

Our experience encompasses all power networks, including long distance power transmission lines, HV substations as well as medium voltage distribution networks for industrial & utility sectors.


Supreme’s engineers lead feasibility studies, planning, detailed design & independent technical appraisal. We integrate technical strength with services including the project management that meet client’s all round needs.

Supreme collaborates with clients to bring value beyond the base requirement & realize their bigger goal. To do this, we often challenge standard approaches. We pioneered a new norm with our design for 132kV Sub-Stations at Delta & Abia State, Nigeria for Power Holding Company of Nigeria PLC. Its footprint is significantly smaller in comparison to other traditional substations.

Supreme offers services which include:
