Endogenous Capacity Expansion Calculations

The document details the step-by-step calculations LEAP employs to determine endogenous capacity expansion, accounting for existing capacity, capacity values for intermittent renewables, peak system power requirements based on load factors, and the planning reserve margin.

• LEAP determines existing capacity by summing exogenous capacity and endogenous capacity added within the previous lifetime years, adjusted by a 'Capacity Value' which accounts for the lower capacity value of intermittent renewable energy processes compared to thermal power plants.
• Peak system power requirements are calculated by dividing the total energy requirement by the product of the module load factor and the number of hours in a year (8760).
• The required endogenous capacity additions are derived from the difference between the planning reserve margin and the reserve margin before additions, multiplied by the peak requirement; these additions are then allocated to processes in the order they appear on the Endogenous Capacity screen until the requirement is met.
