Description
availability = availableHours/contractedHours; payment = capacityKw*paymentPerKw*availability.
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.
availability = availableHours/contractedHours; payment = capacityKw*paymentPerKw*availability.
When to use this tool
Use Capacity Payment Availability Adjustment Term when reconciling a specified energy credit, allocation or settlement term.
How to use the tool and how it works
- Enter capacityKw, paymentPerKw, availableHours, contractedHours. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read availability, payment. Use the output convention below.
Require nonnegative capacityKw, positive contractedHours and availableHours in [0,contractedHours]. availability = availableHours/contractedHours; payment = capacityKw*paymentPerKw*availability.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| capacityKw | Capacity Kw | Required. Finite number; minimum 0. |
| paymentPerKw | Payment Per Kw | Required. Finite number. |
| availableHours | Available Hours Unit: h. | Required. Finite number; minimum 0. |
| contractedHours | Contracted Hours Unit: h. | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| availability | Availability | Required. Finite number. |
| payment | Payment | Required. Finite number. |

}Limitations and assumptions
- paymentPerKw is the full contracted-period currency/kW rate. Availability is a simple hour fraction; contractual tests, penalties and actual payment eligibility are omitted.
- 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.
