Reason why universal circuit breakers are always storing energy
Universal circuit breakers employ mechanical springs as a primary means of energy accumulation. When the breaker remains in the closed position, the mechanical spring mechanism engages and compresses, effectively storing energy for future use. [pdf]
Storing potential and gathering energy
The economics of energy storage strictly depends on the reserve service requested, and several uncertainty factors affect the profitability of energy storage. Therefore, not every storage method is technically and economically suitable for the storage of several MWh, and the optimal size of the energy storage is market and location dependent. Moreover, ESS are affected by several risks, e.g.: [pdf]
The switch is closed without storing energy
There is a switch energy storage contact in series in the closing circuit, that is to say, the switch cannot be closed without energy storage.However, there is no non-energy storage contact in series in the opening circuit. So even if the switch is not charged, it can be jumped off. [pdf]
