Constructing Reliable Infrastructure for Grid Stability

Synchronous condenser sites are a critical part of the UK’s energy network, supporting voltage control and system balance as renewable generation expands.

ACS Construction Group delivers the civil and electrical infrastructure behind these projects, bringing proven capability across complex, high-voltage environments.

Our teams manage the full scope of construction including: groundworks, reinforced foundations, cable installation, and associated infrastructure, all delivered in line with National Grid and DNO standards.

We coordinate with project designers and equipment suppliers to ensure every facility is built safely, accurately, and ready for energisation.

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.

Civil and Electrical Works for High-Voltage Projects

Each synchronous condenser site presents unique technical and logistical demands. ACS Construction Group manages these projects with the same discipline applied across our wider energy portfolio, clear coordination, safe working practices, and uncompromising attention to build quality.

Our civil and electrical teams handle all site construction, forming heavy-duty foundations for the rotating equipment, cable trenches, ducts, and control areas, and preparing all interfaces for electrical installation. We sequence and supervise every phase to maintain programme integrity, manage stakeholder coordination, and keep works compliant with National Grid and DNO requirements.

Through consistent delivery standards and transparent site management, ACS ensures every synchronous condenser facility is built to perform safely, efficiently, and ready for energisation.

Civil and Electrical Works for High-Voltage Projects

Integrated Energy Infrastructure Expertise

Synchronous condenser projects build on ACS Construction Group’s established experience across energy generation, storage, and grid connection schemes.

Our teams work on complex, multi-technology sites that combine electrical, mechanical, and civil disciplines including Battery Energy Storage Systems (BESS), Combined Heat and Power (CHP), and onshore wind infrastructure.

This cross-sector knowledge allows ACS to manage shared interfaces, coordinate with multiple contractors, and deliver consistent construction standards across co-located energy assets.

We understand the operational requirements, safety constraints, and technical tolerances that define modern grid infrastructure, ensuring every project supports the stability and performance of the wider network.
