Description
Calculate a supplied PPA price-difference settlement term.
Energy prices and charges depend on energy units, demand units, standing-charge days, tariff periods and settlement sign conventions. Purchased-energy losses differ from delivered-energy fractions, and signed prices can produce negative monetary terms. Nominal battery cost allocations are supplied scenarios rather than physical aging forecasts.
Calculate a supplied PPA price-difference settlement term.
When to use this tool
Use PPA Settlement Price Difference when you already have contractPricePerEnergy, referencePricePerEnergy, settledEnergy and need to calculate a supplied PPA price-difference settlement term.
How to use the tool and how it works
- Enter contractPricePerEnergy, referencePricePerEnergy, settledEnergy. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read priceDifference, settlementAmount. Use the output convention below.
Require settledEnergy>=0; difference=contractPricePerEnergy-referencePricePerEnergy, amount=difference*energy.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| contractPricePerEnergy | Contract Price Per Energy | Required. Finite number. |
| referencePricePerEnergy | Reference Price Per Energy | Required. Finite number. |
| settledEnergy | Settled Energy | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| priceDifference | Price Difference | Required. Finite number. |
| settlementAmount | (contract-reference price)*settledEnergy under this supplied sign convention; no payer is inferred. | Required. Finite number. |

}Limitations and assumptions
- Prices may be signed. The sign follows this chosen subtraction; actual payer, contract, basis adjustments and settlement obligations are not determined.
- 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
Reconcile the actual meter series, tariff, contract and billing definitions for an account or market question. Use a complete cash-flow or physical-energy model when needed; a single block overlap, index ratio or supplied settlement term cannot establish actual charges or performance.
