Description
curtailedMwh = availableMwh-deliveredMwh; compensatedMwh = curtailedMwh*compensatedFraction; payment = compensatedMwh*contractPrice.
Energy contracts and credit accounts distinguish quantities accrued, used, available, curtailed, expired or qualified. A numeric balance applies an explicit convention; it does not establish which contractual or market rules actually apply.
curtailedMwh = availableMwh-deliveredMwh; compensatedMwh = curtailedMwh*compensatedFraction; payment = compensatedMwh*contractPrice.
When to use this tool
Use Power Purchase Curtailment Compensation Term when reconciling a specified energy credit, allocation or settlement term.
How to use the tool and how it works
- Enter availableMwh, deliveredMwh, compensatedFraction, contractPrice. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read curtailedMwh, compensatedMwh, payment. Use the output convention below.
Require 0 <= deliveredMwh <= availableMwh and compensatedFraction in [0,1]. curtailedMwh = availableMwh-deliveredMwh; compensatedMwh = curtailedMwh*compensatedFraction; payment = compensatedMwh*contractPrice.1
| Input field | Meaning and units | Accepted input |

| contractPrice | Contract Price | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| curtailedMwh | Curtailed Mwh | Required. Finite number. |
| compensatedMwh | Compensated Mwh | Required. Finite number. |
| payment | Payment | Required. Finite number. |

}Limitations and assumptions
- contractPrice is currency/MWh. Availability and compensation eligibility are supplied, not verified contractual rights; negative prices can produce negative payment.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review actual program rules, contract terms and dated records before treating a calculated balance or payment as due.
