Battery Energy Storage Systems (BESS) play a pivotal role in the transition to a low-carbon, decentralised energy system. As the UK and Ireland increase their reliance on intermittent renewable sources like wind and solar, the need for flexible, responsive energy storage has never been greater. BESS projects are now essential infrastructure, balancing supply and demand, supporting grid stability, and enabling the efficient use of clean energy.
The sector has grown rapidly in recent years, driven by falling battery costs, evolving market mechanisms, and a growing appetite from investors and developers. But with this growth comes complexity. BESS projects must navigate a challenging landscape of planning policy, safety regulation, grid connection requirements, and environmental considerations. From fire safety and noise to land use and visual impact, these are not plug-and-play systems—they require careful, expert-led delivery.
At Arthian, we’ve been supporting BESS projects since the early days of the sector. Our multidisciplinary team brings together planners, engineers, environmental consultants, and safety professionals to deliver battery storage schemes that are compliant, efficient, and future-ready.
We provide integrated consultancy services for BESS projects across the UK and Ireland, supporting clients from feasibility through to operation. Our key services include:
Battery storage projects are complex, multidisciplinary undertakings. Arthian brings together the full range of expertise needed to deliver them successfully—from early-stage feasibility to long-term operation.
We help clients identify and evaluate potential BESS sites using GIS analysis, grid availability studies, financial modelling and planning risk assessments. Our feasibility reports provide clear, evidence-based recommendations to support investment decisions and land acquisition.
Our RTPI-accredited planners lead the preparation of planning applications, coordinating inputs from environmental, engineering, and safety specialists. We manage stakeholder engagement, public consultation, and negotiations with planning authorities to secure timely, robust consents.
We also support:
Our environmental and safety consultants deliver a full suite of assessments to support planning and compliance, including:
We ensure that risks are identified early and mitigated effectively, supporting safe, sustainable design and smooth planning outcomes.
Our engineers support the design of access roads, drainage systems, substation infrastructure, and cable routes. We also provide civil and structural input for battery enclosures, fire walls, and ancillary buildings. Our designs are practical, cost-effective, and aligned with planning and safety requirements. We also offer technology choice specification and charge/discharge cycle design.
During construction, we provide:
We help ensure that construction is delivered safely, legally, and with minimal environmental impact.
Once operational, we support clients with:
We help demonstrate the long-term value and compliance of your BESS asset.
We’ve supported BESS projects up to 100MW+ across the UK.
Our team includes planners, engineers, environmental scientists, and safety consultants.
We work as one team, reducing handover risks and ensuring joined-up thinking across disciplines.
We stay ahead of evolving planning policy, grid codes, and environmental regulation.
We tailor our support to your project’s scale, location, and commercial drivers—delivering value at every stage.
We’d love to hear from you – whether you have a question, a project in mind, want to explore job opportunities, or just want to say hello.
