Specifying Capacity Data

The document outlines four approaches to capacity data in LEAP: ignoring capacity limits, using exogenous capacity for manual control of additions, using endogenous capacity for automatic timing based on reserve margins, and using least-cost optimization for automated selection and timing of capacity. It notes that optimization requires detailed cost data, whereas the other methods do not.

• LEAP allows users to ignore capacity constraints entirely, which is useful for sectors where capacity limits are not critical, such as informal charcoal making. In this mode, users only specify the share of each process via the Process Share variable.
• Users can manually control capacity additions and timing using the Exogenous Capacity variable, or use a hybrid approach where the Endogenous Capacity variable allows LEAP to determine the timing of additions to maintain a specified Planning Reserve Margin.
• LEAP provides a least-cost optimization methodology that automatically determines both the type and timing of capacity additions, as well as process dispatch. This approach is activated via the Optimize variable at the module level.
• The optimization approach requires more comprehensive data than simulation-based methods, specifically requiring fully defined capital, O&M, and fuel costs for each process, whereas the other three methods can function without cost data.
