eng.levelized-cost-storage Calculator
Calculates Levelised Cost of Storage (LCOS) from capital, O&M, efficiency losses, and cycle life, enabling comparison between storage technologies. LCOS is the storage equivalent of LCOE — lithium-ion LCOS has fallen 90% since 2015 to approximately $0.10–0.15/kWh.
Inputs
Capex Per Kwh
Reference formula or conversion factor shown for context.
Opex Per Kwh Yr
Reference formula or conversion factor shown for context.
Cycles Per Year
Reference formula or conversion factor shown for context.
Lifetime Years
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Roundtrip Eff Pct
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
