A BESS can have energy left in the battery—but still be unable to deliver it.
That hidden gap is called stranded capacity, and it can quietly reduce BESS revenue over time.
SOC estimation drift, cell imbalance, overly conservative cutoff voltages, and disconnected BMS/EMS control can all leave usable battery capacity inaccessible.
The battery has not necessarily lost that energy.
The system simply cannot safely use it.
For BESS asset owners, this means standard metrics such as SOH and round-trip efficiency may not tell the complete financial story.
