Battery Energy Storage Systems (BESS) are rapidly becoming essential for stabilizing renewable-heavy grids. But before any BESS can connect to the UK distribution or transmission network, it must pass through rigorous engineering, safety, and grid-compliance checks.
Here’s why specialized HV engineering is mandatory.
1. High Fault Levels Require Advanced Protection Design
BESS can inject high currents during faults. Special studies include:
Short circuit analysis
Relay coordination
Breaker sizing
Fault ride-through (FRT) requirements
2. Need for Accurate Grid Compliance Studies
All BESS projects in the UK must meet:
G99 requirements
G5/5 harmonics standards
Steady-state voltage guidelines
Fault-level constraints
3. Complex Control & SCADA Integration
BESS requires:
EMS/BMS integration
SCADA communication
Real-time grid interaction
Remote monitoring
4. Thermal & Fire Safety Engineering
Lithium-ion storage requires:
Fire suppression design
Ventilation systems
Thermal runaway protection
