Calculation method
Calculation method
Incremental yearly cashflows (JSON)
Compare constant old/new annual yields; deduct first-year lost generation and capital cost; no escalation or discounting.
Undiscounted incremental net value (USD)
Compare constant old/new annual yields; deduct first-year lost generation and capital cost; no escalation or discounting.
Incremental generation over horizon (kWh)
Compare constant old/new annual yields; deduct first-year lost generation and capital cost; no escalation or discounting.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Compare constant old/new annual yields; deduct first-year lost generation and capital cost; no escalation or discounting. 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.
