Battery Energy Storage System (BESS) Planning and Environmental Consultancy

Specialist planning support for grid-scale and co-located battery storage projects

Battery storage is now one of the most active areas of UK renewable development. With grid flexibility more valuable than ever, developers are bringing forward BESS projects at pace, both as standalone assets and co-located with solar and wind. But the planning landscape is evolving quickly, and getting a scheme consented takes a clear understanding of safety, policy, and local sensitivities. Engena provides end-to-end planning and environmental consultancy for BESS projects of all sizes, from small community-scale systems to grid-connected schemes of 100MW or more. We help developers navigate a fast-moving planning environment with projects built on strong evidence and sound design.

What is a Battery Energy Storage System?

‍

A Battery Energy Storage System (BESS) stores electricity for use when it's needed most. These systems charge from the grid (or from co-located generation such as solar or wind), then discharge when demand is high or supply is low.

‍

Most modern UK projects use lithium-ion technology, prized for its high energy density, efficiency, and rapid response times. BESS sites range from a few megawatts on brownfield plots to large-scale installations of several hundred megawatt-hours, often co-located with renewable generation or connected directly to the transmission network.

‍

Why battery storage matters

‍

As the UK adds more wind and solar to the grid, storage becomes essential. Without it, renewable generation is harder to balance against demand, and the grid becomes harder to manage.

‍

BESS projects deliver flexibility. They smooth out intermittent generation, provide grid services such as frequency response, and help reduce curtailment of renewable energy. For developers and landowners, they offer a fast route to revenue, often with shorter construction timelines and smaller site footprints than other renewable technologies.

How Engena supports BESS developers

‍

We work with BESS developers, landowners, and co-location partners from site identification through to planning determination and beyond. Our services across the battery storage sector include:

‍

Site appraisal and constraint mapping to assess viability early
Environmental Impact Assessments (EIA) and/or Environmental Reports
Planning applications including full Design and Access Statements
Fire safety and emergency response planning engagement
Noise and air quality assessments
Grid connection and DNO liaison support
Public consultation and stakeholder engagement
Appeals and planning refusal support

‍

Whether you're developing a standalone 20MW BESS or a co-located scheme alongside a major solar or wind project, we bring the same strategic focus: identify constraints early, engage the right stakeholders, and deliver a consent that holds up.

‍

Key considerations for BESS development

‍

Battery storage projects come with a distinct set of planning and environmental challenges:

‍

Fire safety, thermal runaway, and emergency access
Noise impact from inverters and cooling systems
Visual impact and screening of containers and compounds
Proximity to substations and grid connection points
Local planning policy on BESS, which varies significantly by authority
Engagement with local fire and rescue services
Flood risk, especially on lower-lying grid-adjacent sites
Ecology, biodiversity net gain, and habitat considerations

‍

Community concern around battery safety is real and growing, particularly following well-publicised incidents elsewhere. We help developers get ahead of these concerns with transparent engagement, robust safety evidence, and planning documents that answer the hard questions before they're asked.
