We review the electrical arrangement from the high-voltage connection through transformers and medium-voltage distribution. Drawings, equipments spécifications, and supplier information are compared against the agreed project requirements. 

We examine how the proposed arrangement supports normal opération, planned outages, equipments isolation, and future expansion. Together with your team, we consider practical questions : can equipment be maintained without interrupting the entire installation? Are switching assumptions clear? Have acces and equipment-replacement needs been considered?

We review the supplies supporting protection, circuit-breaker operation, control equipment, and other essential substation functions. This includes station batteries, chargers, distribution arrangements, backup provisions, and alarms. We examine the documented loads and autonomy assumptions, and highlight dependencies that need further justification or testing. 

We examine protection principles, trip circuits, interlocks, opérating modes, and metering boundaries. The focus is on what the equipment must do, how functions interact and who is responsible for each part. 

For BESS projects, this include reviewing the documented relationship between charging and discharging limits, plant controls, protection actions, and applicable grid-operator instructions.

We help bring opérational needs and environmental considerations into the same design discussion. Equipment positioning, transformer noise screen, building appearance, colors, and landscape screening can be considered alongside ventilation, access, fire separation, and oil containment.

We distinguish contractual obligations from optional improvements and clarify boundaries between the owner, contractors, equipment suppliers, and grid operator.

We review factory acceptance test (FAT) and site acceptance test (SAT) plans against the agreed functions and interfaces.
