Description
Calculate a capture-price gap and signed relative discount.
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 capture-price gap and signed relative discount.
When to use this tool
Use Renewable Capture Price Discount when you already have capturePrice, referenceMarketPrice and need to calculate a capture-price gap and signed relative discount.
How to use the tool and how it works
- Enter capturePrice, referenceMarketPrice. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read signedPriceGap, relativeDiscount. Use the output convention below.
Require referenceMarketPrice!=0; gap=reference-capture and relativeDiscount=gap/reference.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| capturePrice | Capture Price | Required. Finite number. |
| referenceMarketPrice | Reference Market Price | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| signedPriceGap | Signed Price Gap | Required. Finite number. |
| relativeDiscount | (reference-capture)/reference; a signed reference can reverse its interpretation. | Required. Finite number. |

}Limitations and assumptions
- A negative reference reverses ratio interpretation; the result need not lie in [0,1]. No capture profile, market average or revenue is estimated.
- 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.
