The UK’s 2050 Net Zero targets demand rapid expansion of energy storage, yet battery energy storage systems (BESS) face significant planning challenges. Developers encounter inconsistent regulations, lack of technical expertise, and local opposition, leading to project delays and inflated costs.

BESS projects often exceed the capacity of previously assessed developments, complicating local authority evaluations. Inconsistencies in planning outcomes are evident, as seen with the divergent decisions by Horsham and Mid Sussex District Councils on similar BESS applications.

Councils vary in their fire safety requirements and landscape screening policies, creating a complex regulatory environment for developers. Despite a seven-fold increase in installed BESS capacity from 2020 to 2025, public fear regarding fire risks persists, fueled by misinformation. To accelerate deployment, comprehensive improvements to planning frameworks and technical capacities are necessary.
