Substation Design & Engineering
From substation site design to energization and beyond
A substation is a vital component of the electrical power system that plays a crucial role in transmitting and distributing electricity from power generation sources to end-users. Effective substation design requires a deep understanding of electrical engineering principles.
Expanse engineers perform key analysis of electrical loads, voltage levels, safety measures and environmental considerations. These elements are taken into account when designing a substation to protect personnel and equipment from electrical hazards while helping maintain grid stability by balancing load and ensuring a consistent supply of power.

LAYOUT & CONFIGURATION
Our engineers determine the layout and configuration of the substation, including the placement of equipment such as transformers, circuit breakers, switches and busbars. We layout each design to optimize space, facilitate maintenance, and ensure safety.
EQUIPMENT SELECTION
We select and specify the type and capacity of equipment required for the substation, such as transformers, circuit breakers and protective relays. The choice of equipment depends on factors like load requirements, fault protection, and environmental conditions.
SAFETY PROTECTION
Safety is a paramount consideration in substation design. Expanse engineers implement various safety measures, including proper grounding, fencing, signage, protection and control equipment, redundancy and safety locks to protect both personnel and equipment.
COMPLIANCE & REGULATION
Substation design must comply with industry standards, codes and regulations. Our engineers stay informed about the latest regulatory requirements and ensure that every Expanse design meets these standards.
