TED Expressions

The document describes the functionality of TED for entering environmental loadings, highlighting the use of mathematical expressions to link emissions to fuel composition data stored in LEAP.

• Environmental loadings in TED can be defined as constant numeric values or as mathematical expressions based on the chemical composition of fuels, which is particularly useful for calculating CO2 emissions from coal-fired power plants where emissions depend on carbon content.
• Using mathematical expressions that reference the LEAP fuels database—such as calculating loading based on CarbonContent, FractionOxidized, and constants—ensures that environmental loadings update automatically when the fuels database changes and allows a single set of effects to be applicable across different regions with varying fuel compositions.
