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 coordi
