Description
chargedEnergy = energy/(1-lossFraction) when grossUpLosses is true, otherwise energy; costAdder = chargedEnergy*suppliedAdderPerEnergy.
Energy price comparisons require consistent delivered or input energy units, efficiency, calorific basis and reporting period. Dividing by efficiency increases the input needed for a delivered unit; nominal price differences alone need not represent a saving.
chargedEnergy = energy/(1-lossFraction) when grossUpLosses is true, otherwise energy; costAdder = chargedEnergy*suppliedAdderPerEnergy.
When to use this tool
Use Dispatch Cost Adder Component when checking one supplied energy-price normalization or cost contribution.
How to use the tool and how it works
- Enter energy, suppliedAdderPerEnergy, suppliedLossFraction, grossUpLosses. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read costAdder, chargedEnergy. Use the output convention below.
Require nonnegative energy and suppliedLossFraction in [0,1). chargedEnergy = energy/(1-lossFraction) when grossUpLosses is true, otherwise energy; costAdder = chargedEnergy*suppliedAdderPerEnergy.1

}Limitations and assumptions
- Losses are a fraction of gross energy. The adder may be signed and is supplied rather than derived from network losses, dispatch costs or a tariff.
- 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
Use the full tariff, operating profile and cost boundary when assessing real bills, investments or load-shifting decisions.
