Specifying Capacity Data

This guide from the Stockholm Environment Institute explains four methods for specifying capacity data within the Low Emissions Analysis Platform (LEAP) Transformation module, ranging from ignoring capacity limits to full least-cost optimization.

• Users can choose to ignore capacity constraints in a Transformation module, which is useful when data is unavailable or limits are unimportant, such as in informal sectors like charcoal making. In this mode, only the Process Share variable is used to specify the share of each process, and the Capacities check box must be unchecked in Module Properties.
• LEAP allows for exogenous capacity specification where the user determines the exact amounts and dates of future capacity additions. This is configured by enabling the Capacities checkbox in the Module Properties screen.
• A hybrid approach exists where users specify existing, planned, or committed capacity via the Exogenous Capacity variable, while the Endogenous Capacity variable allows LEAP to automatically determine the timing of additions. LEAP triggers these additions by monitoring the module's reserve margin to ensure it remains above a user-specified Planning Reserve Margin.
• LEAP provides a least-cost optimization methodology that determines both the type and timing of capacity additions, as well as process dispatch. This is activated via the Optimize variable at the module level for specific scenarios. Unlike simulation-based approaches, optimization requires comprehensive data on capital, O&M, and fuel costs for every process.
