About this Gig
A substation is more than a collection of transformers and switchgear. The equipment, protection, ratings, connections and electrical parameters have to work together as one system.
I provide MV/HV substation engineering and electrical design for solar PV, utility, industrial and commercial power projects, translating project requirements into practical engineering documentation.
Depending on your project scope, I can support:
- MV/HV substation design and engineering
- Electrical Single Line Diagram (SLD)
- Transformer sizing and selection
- MV/HV switchgear configuration
- Busbar and feeder arrangement
- CT, VT/PT and metering configuration
- Protection and electrical equipment selection
- Earthing/grounding system design
- Cable sizing and voltage-drop calculations
- Short-circuit and load-flow studies
- Equipment schedules and technical documentation
- Design review against project or utility requirements
- I can work from your project specifications, existing SLD, load data, grid information, equipment schedules or preliminary design and develop the required engineering deliverables around the available information.

FAQ
What information do you need for substation design?
I typically need the voltage level, project capacity, load data, point of connection, existing SLD, transformer requirements, grid or utility information, protection requirements and applicable standards. Available project documents can be reviewed to establish the correct engineering scope.
Can you design MV and HV substations for solar projects?
Yes. I can support MV/HV substation engineering for solar PV and other power projects, including transformer selection, switchgear configuration, SLD development, feeder arrangements, protection considerations, metering and supporting electrical calculations based on the project requirements.
Can you create a substation Single Line Diagram?
Yes. I can develop or revise an electrical Single Line Diagram showing the major substation equipment and connections, including transformers, MV/HV switchgear, feeders, busbars, CTs, VTs/PTs and other relevant equipment according to the available project information.
Do you provide transformer and switchgear sizing?
Yes. Transformer and MV/HV switchgear selection can be included based on the project capacity, voltage level, load requirements, fault level, operating conditions and applicable specifications. The selected ratings and assumptions can be documented as part of the engineering deliverables.
Can you include protection and metering in the substation design?
Yes. Where sufficient project information is available, the substation design can incorporate protection and metering requirements, including CT/VT considerations, feeder protection, transformer protection and relevant equipment arrangements. Final protection settings require the applicable utility
Can you work from an existing or incomplete substation design?
Yes. I can review an existing SLD, preliminary substation design, equipment schedule or engineering package and identify areas requiring development or revision. This is useful when an existing design needs technical updates, additional calculations or alignment with project requirements.
