Battery Energy Storage Systems (BESS)

Securing a viable grid connection is one of the most critical factors in the success of a Battery Energy Storage System project. Our multidisciplinary teams support developers through grid connection strategies, site feasibility assessments and the planning of associated electrical infrastructure, helping to ensure projects are both technically and commercially viable. We work closely with clients to understand network constraints, infrastructure requirements and development risks, providing coordinated support that aligns planning, engineering and environmental considerations. By addressing these challenges early, we help improve project certainty and support efficient delivery.

Battery Energy Storage Systems introduce unique operational and safety considerations that must be carefully managed throughout the asset lifecycle. Our process safety specialists help developers and asset owners identify, assess and mitigate risks associated with battery technologies through hazard studies, fire risk assessments, DSEAR considerations and operational safety reviews. We provide practical advice that supports safe design, regulatory compliance and long-term operational resilience, helping operators protect people, assets and business continuity. This integrated approach ensures safety is embedded from project development through to operation.

As critical energy infrastructure, BESS assets must be resilient to both current and future environmental conditions. Our specialists provide flood risk assessments, drainage strategies and climate resilience studies that help clients understand vulnerabilities and develop practical mitigation measures. We support the design of facilities that are better protected against flooding, extreme weather and changing climate conditions, helping to safeguard operational performance and long-term asset value. By integrating resilience planning into project development, we help create infrastructure that can perform reliably throughout its operational life.

Planning and consenting can present significant challenges for battery storage developments, particularly where environmental constraints, stakeholder concerns or operational risks require careful consideration. Our planning and environmental experts support clients through planning strategy, environmental assessments, stakeholder engagement and regulatory approvals, helping projects progress efficiently through the development process. By identifying constraints early and developing robust technical evidence, we help reduce delays, minimise risks and improve the likelihood of successful project outcomes. This joined-up approach creates a clearer route from concept through to delivery.

Battery energy storage plays a vital role in enabling a more flexible, resilient and low-carbon energy system. Our sustainability, engineering and infrastructure specialists help clients develop projects that support Net Zero ambitions, strengthen energy security and enhance the performance of renewable energy networks. From project feasibility and development through to operational optimisation and long-term asset management, we provide integrated advice that helps maximise environmental, operational and commercial value. By supporting the deployment of future-ready energy infrastructure, we help clients contribute to the UK’s evolving energy landscape while creating sustainable long-term returns.
