- Buy electricity price (USD/kWh)
- 0.1
- Round-trip efficiency (fraction)
- 0.85
- Cycle cost per discharged kWh (USD/kWh)
- 0.03
- Break-even sell price (USD/kWh)
- $0.15
- Required price spread (USD/kWh)

Try another scenario
- Buy electricity price (USD/kWh)
- 1.1
- Round-trip efficiency (fraction)
- 0.85
- Cycle cost per discharged kWh (USD/kWh)
- 0.03
- Break-even sell price (USD/kWh)
- $1.32
- Required price spread (USD/kWh)
- $0.22
Calculation method
Calculation method
Break-even sell price (USD/kWh)
Per delivered kWh, purchased energy costs buy price/round-trip efficiency; add supplied cycle cost.
Required price spread (USD/kWh)
Per delivered kWh, purchased energy costs buy price/round-trip efficiency; add supplied cycle cost.
Symbols and units
- a
- Buy electricity price (USD/kWh)
- b
- Round-trip efficiency (fraction)
- c
- Cycle cost per discharged kWh (USD/kWh)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Per delivered kWh, purchased energy costs buy price/round-trip efficiency; add supplied cycle cost. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
