Utility & Secondary Distribution

Plan a distribution substation upgrade, feeder extension or transformer replacement around the circuits that must stay live. The outage plan determines which feeders can carry the transferred load while the new transformer is connected.

Industrial Facilities

Compare power distribution for mine electrification and microgrids, semiconductor fabs and battery cell factories. A mine may shed crushers to keep pumps running. A fab extension needs to keep air handling and chilled water available to the operating line.

Infrastructure & Public Facilities

Explore EV charging station transformers, AI data center power distribution, port shore power and water treatment plant power supply. A depot is often constrained by its import limit. A data hall must also account for the IT and cooling loads that transfer to the surviving supply during maintenance.

Renewable & Distributed Energy

Trace the AC connection for grid-scale battery energy storage (BESS) and solar-plus-storage substations from the converter to the grid. A shared export limit governs the grid meter. Check the PV and battery branches separately because they can carry different power flows behind that meter.

Project example

How power reaches an EV charging depot

A fleet depot can have more dispensers than power cabinets. At the utility connection, the important figure is the combined AC input of the cabinets charging at the same time, plus other loads on the site. See the depot sizing example.

Example supply path for an MV-connected depot
  1. Grid connectionUtility MV supply

    Confirm the service voltage and permitted import with the utility.

  2. Distribution equipmentMV incoming equipment transformer LV outgoing feeder
  3. Charging equipmentAC input to the power cabinets

    Confirm how many dispensers share each cabinet and which cabinets can operate together.
