Delivering Civil Engineering Works for Hydropower

At ACS, we construct reinforced foundations, retaining structures and supporting infrastructure that allow hydropower schemes to progress. Our role is to deliver the civil engineering works around generating equipment, including bases, bunded areas, control buildings and water management structures. Every element is built to exact utility specifications and compliance standards, with works sequenced to suit specialist hydro installations and the constraints of remote environments.

We draw on experience across substations, battery storage and renewable energy projects to apply proven delivery methods in hydro settings. By planning access, logistics and sequencing in detail, we reduce construction risk and provide stable, durable structures that prepare complex hydro sites for installation and long-term operation.

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.

Grid Connection Works in Hydro Schemes

Constructing substation bases, cable trenches, ducting networks and jointing bays, ACS prepares hydropower projects for integration into the grid. These works are delivered to strict utility specifications and sequenced around planned outage windows and live high-voltage environments. Our teams coordinate with network operators and electrical contractors to manage access, safety and programme requirements, reducing the risk of disruption during installation.

Beyond the immediate build, we take ownership of the civil engineering interface across multiple stakeholders, ensuring that each stage of infrastructure delivery aligns with electrical works. This integrated approach keeps programmes controlled and provides the foundations required to connect hydro assets securely into the national network.

Access and Enabling Works on Hydropower Sites

Shaping remote or difficult terrain into a workable site is often the first challenge on hydropower schemes. ACS delivers enabling packages that include bulk earthworks, access road construction, drainage systems, retaining walls and temporary works, tailored to the conditions of each location. These works are sequenced to provide safe logistics for heavy plant and materials, while protecting surrounding environments from unnecessary impact.

We plan enabling activities in detail, programming them to support follow-on trades such as foundation and utility installation. By establishing stable ground conditions, controlled access routes and service-ready platforms, we reduce construction risk and create the conditions needed for hydropower infrastructure to be built safely and efficiently.

Access and Enabling Works on Hydropower Sites

Why Developers Choose ACS

ACS has a proven record delivering civil engineering works for substations, grid connections, battery storage, wind and solar projects. Our teams operate confidently in high-voltage and regulated environments, where sequencing, logistics and compliance are critical. This experience transfers directly into hydro schemes, where sites are often remote, complex and require careful planning.

Clients choose ACS for:

Civil engineering delivery across renewable and utility projects
Teams trained to work in high-risk and high-voltage
environments
Detailed planning of logistics, sequencing and access
Hands-on leadership and site-wide coordination
A compliance-driven approach that keeps programmes controlled

We take responsibility from pre-construction through to handover, identifying risks early, sequencing works carefully and delivering the civil engineering works that make hydro sites buildable and ready for specialist installation.
