Building a new substation or retrofitting the old one is a complex process full of design and engineering tasks to be worked on. The main steps in substation design and engineering are as follows:
Foundation design and control house design. Volume IX, Substation Structures. Covers the design of bus support structures and connectors. Volume X, Grounding. Covers the design of the ground grid for safety and proper operation. Volume XI, Protective Relaying. Covers relay types, schemes, and instrumentation. Volume XII, Auxiliary Systems. Design The main considerations taking into account during the design process are: 1. Reliability 2. Cost (sufficient reliability without excessive cost) 3. Expansion of the station, if required. Selection of the location of a substation must consider many factors: 1. Sufficient land area 2. Necessary clearances for electrical safety 3.
Step 1 – switching system
Selection of a substation switching system: ring bus, breaker-and-a-half, etc. based on reliability requirements.

Preparation of a key plan which should show the location of all components of a substation and their interconnections, as well as steel structures, control house, fire walls, driveways, fence and property line.
Step 3 – equipment selection and ordering

They specify transformers, breakers, etc., request bids form approved vendors, evaluate the bids, place the order with a winning bidder, and participate in testing and commissioning of equipment.
