State of Charge: How Much Energy Is Actually Available in a BESS?
A practical example showing how state of charge determines the energy available in a BESS, how it affects discharge duration, and why SOC becomes a key constraint in battery optimization.
What Does 100 MW / 200 MWh Actually Mean?
A simple numerical explanation of MW, MWh, battery duration, and why power and energy capacity represent different constraints in a BESS.
