Our largest EV project to date: the electrical design and construction of a 1MVA dedicated supply — LV switchroom, switchgear and distribution — feeding 60 × 22kW Autel MaxiCharger AC Ultra connectors. A large-scale commercial EV charging installation delivered by NICEIC approved electrical contractors.
Our largest EV project to date — a large-scale commercial EV charging installation where the electrical infrastructure, not the chargers, was the real job.
Novuna needed the electrical infrastructure to support a 60-bay EV charging hub. Not the chargers themselves — the power to run them. Sixty 22kW connectors drawing simultaneously represents a demand no ordinary commercial supply can absorb, which put this firmly in dedicated-supply territory.
A project at this scale changes the nature of the work entirely. You are no longer specifying wall boxes; you are designing an LV switchroom, sizing switchgear, planning distribution runs across a site, and satisfying a Distribution Network Operator that a megavolt-ampere of new demand can be connected safely.
This is precisely the kind of large-scale commercial EV charging installation that separates electrical contractors from charge point resellers. MARA has been NICEIC approved since 2010 and has delivered multi-megawatt commercial projects for names including Sainsbury's, Tesco, Primark and the Ministry of Defence — the same engineering discipline applied here to EV infrastructure.
Full design and construction of the EV charging electrical infrastructure, from incoming supply to the final connector.
Electrical design of a dedicated 1MVA supply purely for EV charging — sized so all 60 connectors can operate simultaneously at full output.
Design and construction of the low-voltage switchroom housing the distribution equipment for the entire charging hub.
Specification and installation of LV switchgear, protection and distribution across the site to each bank of charging bays.
Power supplies engineered and delivered to 60 Autel MaxiCharger AC Ultra connectors — the hardware end of a much larger infrastructure project.
Infrastructure, groundworks and charge point installation across the site.






Infrastructure designed for the demand it will actually see — today and as the fleet grows.
A 1MVA dedicated supply means all 60 connectors can charge at 22kW together — capacity engineered in, not managed around.
A dedicated LV switchroom and switchgear package, designed and constructed for the hub rather than retrofitted to an existing board.
At 60 bays this is among the largest EV charging installations delivered by a North Wales contractor — real evidence for clients weighing up similar schemes.
Infrastructure of this scale is designed with distribution capacity that supports expansion as EV adoption accelerates.
Most EV charging enquiries start with a question about chargers. At scale, the charger is the easy bit. What determines whether a 60-bay hub works is the supply behind it: whether the incoming capacity is genuinely there, whether the switchgear is specified correctly, whether the DNO will approve the connection, and whether the distribution has been designed for real simultaneous demand rather than optimistic averages.
Working from our base in Queensferry on Deeside — with the A494, A55 and the Flintshire Bridge putting most of North Wales and the North West within easy reach — we deliver this class of project across the region and well beyond it, having run commercial work as far as Manchester and Scotland.
If you are planning commercial EV charging installation at any meaningful scale, this is the standard of electrical engineering it requires.

We designed and built the electrical infrastructure for a 60-bay, 1MVA charging hub. If your scheme needs a dedicated supply, an LV switchroom and a G99 connection, that is exactly the work we do.
