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

Just a quick note to say thanks for the great performance thus far on the project. I am fortunate to have the scope to be able to visit site on a regular basis and I must say it’s a pleasure to see consistent productivity from your various site teams across the job. The excellent progress achieved by ACS will now enable our mechanical contractor to mobilise a peak workforce in October working across all work pack areas on the West of Gowy on behalf of the Essar construction team please pass on our thanks to the ACS workforce.

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.

Experience & Understanding

Our team brings sector experience and a deep understanding of what it takes to build energy infrastructure that meets today’s technical, commercial
and compliance standards.

We also understand the pressures facing today’s energy clients, from achieving net-zero targets to meeting complex grid compliance and regulatory requirements. Our delivery is always aligned with the wider commercial and operational context of each project.

How We Work

Energy construction projects require detailed planning and precise delivery.

Grid connection dates, commissioning programmes and technical interfaces all place demands on sequencing and coordination. Managing these effectively is critical to keeping projects on track.

Our team works closely with grid operators, principal designers, OEMs and commissioning teams to ensure every stage of the construction phase is delivered to programme.

We take an active approach to risk management, interface control, and progress reporting, ensuring clients have clear visibility throughout the build.

We operate a culture of openness and collaboration with clients and partners, recognising that transparency is critical to successful energy construction delivery.
