Project Overview

Delta HV designed, built and commissioned the substation and post-meter works for a new EV charging station — the fiftieth plot delivered for the same client. The scheme brought design, civils, plant and protection disciplines together on a tight timescale with meticulous design accuracy and rigorous adherence to safety standards. Open communication and a shared commitment to quality held every milestone, and the substation and post-meter works were commissioned ahead of the site's grand opening, the end client's principal driver, with successful adoption of the contestable works by both the DNO and the IDNO.

Description & Overview of Works

What Delta HV Delivered

01
Design & value engineering
Design across primary, civil, structural, architectural, drainage, electrical and landscaping finishes, with value engineering solutions that saved time and cost during the build.
02
Electrical protection design
Protection design reviews, settings configuration and implementation, and off-site protection panel build at Delta HV's own manufacturing facility.
03
Civils & groundworks
Civils, ground works and drainage, together with below and above ground earthing systems.
04
Procurement & installation
Plant and equipment procurement and installation; 11kV cable jointing and terminations including specialist manufacture terminations; multicore and telecontrol cable installation, termination and testing; and LV lighting, small power and heating.
05
Testing & commissioning
Final on-site testing and commissioning of plant and protection schemes, including the post-meter works serving the charging bays.
06
Completion, adoption & energisation
Completion through to energisation, with adoption of the contestable works by both the DNO and the IDNO.
technical highlight

The fiftieth plot for the same client

Reaching a fiftieth plot for one client is the clearest evidence of repeatable delivery. Delta HV has standardised the design, panel build and commissioning approach across the programme so each new site draws on proven arrangements rather than starting again — shortening the design and approval cycle, keeping quality consistent plot to plot, and holding fixed commercial dates such as a grand opening.
