Power systems engineering / Est. 1985

The current behind
the architecture.

Voltaic designs, builds, and commissions the electrical systems that keep landmark buildings and grids alive.

Four decades wiring the places that cannot afford to go dark.

What we engineer

From the incoming feeder to the last fixture.

High-voltage distribution

Primary substations, switchgear, and transformer halls up to 33 kV, designed for the load you will have in twenty years, not the one you have today.

Standby & UPS resilience

Generator plant and uninterruptible supply with a single rule: the lights never flicker, even mid-fault.

Grid interconnection

From application to energisation. We carry the conversation with the network operator so you do not have to.

Lighting & controls

Scene-level control and addressable lighting that reads as architecture, not as wiring.

Energy modeling

Every distribution board simulated under fault before a single cable is pulled, so commissioning holds no surprises.

Selected work

  1. The Meridian Exchange data centre at night 01 Meridian Exchange Data center / 48 MW A two-storey colocation hall energised in phases while the floor below stayed live.
  2. Saltmarsh Concert Hall interior 02 Saltmarsh Concert Hall Cultural / 6.5 MW Silent power for a room where the quietest passage is 18 decibels.
  3. Kingsway transit interchange platform 03 Kingsway Interchange Transport / 14 MW Traction and station power for 90,000 passengers a day, commissioned over 40 night shifts.

How a project runs.

One team from the first survey to the moment the system goes live. No handoffs, no gaps in accountability.

  1. Survey

    We map every existing circuit and every future load before we draw a line.

  2. Model

    Fault levels, harmonics, and load flow simulated until the design holds under stress.

  3. Build

    Our own engineers on site, so the drawing and the installation never diverge.

  4. Energise

    Staged commissioning with the network operator, switched in under live supervision.

“Voltaic took a substation three firms had called impossible and energised it two weeks early. The room never lost power for a second.”

Eleanor Briggs Director of Infrastructure, Meridian Exchange
