From 1MW depot chargers to 20MW public hubs. We deliver the full electrical infrastructure package for HGV EV charging, from POC application to operational handover.
Every HGV charging infrastructure project follows a structured delivery sequence. Here is exactly what we do at each stage.
HGV electric vehicle charging operates at a fundamentally different scale to car charging. Each HGV bay requires 100 to 400kW. A depot with 10 vehicles charging simultaneously needs 1.5 to 3.5MW of power. A public HGV charging hub with 20 bays may need 4 to 8MW. At this scale, a simple LV connection is not possible. An 11kV or 33kV grid connection, on-site substation infrastructure, and intelligent energy management are all required. USP has delivered HGV charging infrastructure at this scale, including the Voltempo hub at Felixstowe.
Above approximately 1MW, the DNO treats the connection as a bespoke connection. Lead times are typically 18 to 36 months. For a site targeting operation in 2026, the POC application needs to be submitted now. USP develops a POC strategy that identifies the most deliverable connection point, assesses whether 11kV or 33kV is required, and identifies what can be progressed in parallel (BESS selection, substation design, civil works) to reduce the critical path. We submit the application and manage the NGED connection process.
Unmanaged charging is not viable at HGV scale. If 10 HGVs all plug in and charge at full power simultaneously, the peak demand exceeds what most grid connections can economically deliver. An energy management system (EMS) allocates available power dynamically between active chargers, prioritising vehicles with lower state of charge or earlier departure times. Overnight and off-peak staggering further reduces peak demand. USP advises on EMS selection and integration with charger management systems.
A battery energy storage system (BESS) is a highly effective tool for managing peak demand at HGV charging hubs. The BESS charges from the grid during off-peak periods, typically overnight, when electricity is cheapest and network demand is low. During peak charging periods it discharges, reducing the import from the grid and therefore the Maximum Import Capacity contracted with the DNO. This can reduce both connection costs and ongoing network charges. USP assists with BESS sizing, supplier selection, and integration with the EMS.

I contacted USP and within minutes had a chat with Justin who described exactly how the job would be done and provided a comprehensive quote including labour and materials and was able to start the work in just 7 days. Justin and his team were brilliant and did an amazing job. I can highly recommend USP.
Jack and Joel were absolutely amazing this morning and really put themselves out to dig a hole without having to dig another hole in my drive. More work for them but one happy customer.
From the initial quote through to work completion, Justin and his work partner were a mix of professional, knowledgeable, good-humoured, and clear in all explained (I felt an instant ease to agree to the work). The work itself was excellent and they left the place immaculate!
George and Jack come out today to move a gas meter. It wasn't a straightforward job, but they both took time to talk me through what they were doing and what the next steps are. Very friendly and polite and thought about the needs of our family.
Jack and George are great.
Bang on time, completed the work perfectly, no issues. Left the meter really neatly finished. Jack and Joel were very courteous and did a great job.
George and Jack turned up and did a first class job, very friendly and professional. Great job lads.
Jack and Joel were brilliant. Very polite, worked to my highest expectations. Left the area as clean and tidy, as was possible. And explained every step of the process to me, answering any questions I had.
Fantastic work from Jack and Johl.
