Experienced BESS Construction Contractors
At ACS Construction, we understand that battery energy storage systems (BESS) are the future of the UK’s renewable energy infrastructure. These large-scale rechargeable batteries allow you to build renewable energy into your projects from the start. Without the risks of inconsistent performance due to changing weather.
BESS projects carry high technical demands and strict programme pressures, particularly where grid connection and commissioning dates are fixed. We provide complete construction services for battery energy storage sites across the country.
End-to-End BESS Construction Services
Our teams take on responsibility for the entire build, from site preparation through to commissioning readiness. Scope typically includes compound construction, foundation systems, containment and ducting, fire and thermal protection measures, substation interfaces, and grid connection works.
On every project, we pay close attention to site-specific factors too. Space constraints, thermal zoning, fire protection, HV and LV integration and grid interface requirements all shape how a battery storage project is built. We understand these factors and plan construction accordingly.
Groundworks, Civils and Infrastructure For BESS
Long-term operational performance is essential in BESS developments. We deliver detailed groundworks and civil engineering services meeting the specific demands of battery storage projects. Constructed with safety, compliance, and longevity in mind.
Our BESS services include:
- Site clearance, earthworks, and levelling
- Construction of reinforced concrete foundations for battery units, inverters, and substations
- Installation of drainage systems
- Internal access roads, hardstanding areas, and laydown zones
- Security fencing, gates, and perimeter infrastructure
- Ducting and cable trenching to support electrical systems
We work closely with stakeholders to coordinate civil and electrical requirements. Creating a safe and performance-optimised connection between infrastructure and battery components.
Why Choose ACS for BESS Construction?
Battery energy storage systems are still a relatively new technology. This means you need a partner that understands the technical, regulatory, and logistical challenges involved in BESS developments.
Our team has years of experience working on these projects, proactively ensuring they’re delivered safely, efficiently, and in line with programme and compliance requirements. We’ve delivered several energy storage systems, including;
- Standalone grid-connected battery storage sites
- Hybrid battery and solar installations
- BESS integrated with new grid substations
- Battery storage co-located with flexible gas generation
We work with you to deliver careful planning, strong interface management and a clear focus on your programme priorities.
Renewable Energy Projects Delivered For
We’re a chosen partner for some of the leading organisations in the energy and renewable sector, with delivery of many Battery Energy Storage Solutions across the UK.
Tailored BESS Installation and Grid Integration
Successful grid integration is a fundamental part of any BESS project. Our team supports the installation of battery systems by creating a reliable foundation during the construction phase. We provide preparation and installation support for battery storage units and inverter systems, as well as high-voltage and low-voltage cable routing infrastructure.
We can act as principal contractor on standalone BESS projects or as a delivery partner within larger EPC or framework programmes. On principal contractor projects, we manage all on-site delivery, trade coordination, CDM responsibilities and interface management.
On EPC-led programmes, we integrate closely with client teams to provide targeted delivery expertise and support.
