ACS Construction Group Ltd played a pivotal role in the successful execution of the civil and construction works on the Eye Synchronous Condenser project.

ACS’s proactive approach, rigorous quality management, and collaborative spirit ensured successful delivery of a complex, high-value facility in a challenging environment — reinforcing a strong working relationship with British Salt.

The Hinkley Connection Project is a new 57 km high-voltage electricity line that will connect six million homes and businesses to new sources of low carbon energy. It will help the UK to meet ambitious targets to achieve net zero by 2050. The Sandford substation – one of 300 substations throughout England and Wales - is at the heart of the project.

Specialists in Grid Connections for High-Voltage EV Charging

High-voltage EV charging sites rely on well-managed grid connections to stay on schedule. With experience across both 11kV and 33kV networks, ACS supports clients through every stage; from DNO applications to final energisation.

Our teams coordinate closely with ICPs and grid operators to ensure all works are compliant, technically sound, and delivered without delay. This hands-on approach helps de-risk connection timelines and keep projects moving.

What is High-Voltage EV Charging Infrastructure?

High-voltage EV charging infrastructure powers ultra-rapid chargers rated at 150kW, 350kW and above. It connects charging stations to the grid using 11kV or 33kV electrical systems, enabling fast, reliable energy delivery at scale.

HV infrastructure includes substations, transformers, cabling, and grid connections; all built to handle high load demand. This setup is essential for commercial EV charging, fleet depots, and public forecourts where speed, uptime, and scalability are critical.
