7.2 Levelized Cost of Storage (LCOS)
LCOS provides a normalized cost per unit of energy delivered by the storage system over its life. A common definition is:
LCOS = [ Σ_t (CAPEX_t + OPEX_t + C_charge,t) / (1 + r)^t ] / [ Σ_t (E_out,t) / (1 + r)^t ]
where r is discount rate, C_charge,t is the cost of charging electricity (if included), and E_out,t is discharged energy delivered to the grid. Different studies vary in whether charging cost is included, and whether replacement/augmentation is modeled explicitly. LCOS is therefore most useful for comparing options under a consistent modeling boundary.

{"size":"1024x1024","n":1,"transparent_background":false,"prompt":"Create a clean, modern infographic explaining Levelized Cost of Storage (LCOS). White background, simple flat icons, minimal color accents. Title at top: "Levelized Cost of Storage (LCOS)".\n\nCenter: large equation in clear math typesetting:\nLCOS = [ Σ_t (CAPEX_t + OPEX_t + C_charge,t) / (1 + r)^t ] ÷ [ Σ_t (E_out,t) / (1 + r)^t ]\n\nLeft side (numerator) boxed and labeled "Present value of lifetime costs" with three small icon callouts:\n- CAPEX: battery + wrench icon ("Upfront investment")\n- OPEX: clipboard/gear icon ("Operations & maintenance")\n- C_charge: lightning bolt + price tag icon ("Charging electricity cost (optional)")\nAlso show a small timeline with years t=0..N and a discounting arrow "discount by (1+r)^t".\n\nRight side (denominator) boxed and labeled "Present value of lifetime delivered energy" with an icon callout:\n- E_out: power line / grid icon ("Discharged energy delivered")\nAlso show the same timeline and discounting arrow.\n\nBottom footer: two small notes in a subtle gray:\n1) "Studies differ: include/exclude charging cost; model replacements/augmentation differently." \n2) "Best for comparing options with consistent modeling boundaries." \n\nStyle: crisp vector look, readable text, balanced layout, high-resolution."}
