Transformation Analysis

The document provides technical instructions for setting up Transformation analyses in LEAP, detailing the hierarchical structure of modules and processes used to model energy conversion sectors. It outlines the four-step setup process—identifying modules, sequencing them by energy flow, setting properties, and entering technology data—while explaining the roles of feedstock, auxiliary, and output fuels in calculating primary resource requirements.

• Transformation analysis in LEAP simulates the entire energy chain from the extraction of primary resources and fuel imports to the point of final consumption, allowing for alternative scenarios based on different policy and technology assumptions.
• The model is structured hierarchically: modules represent energy conversion sectors (e.g., electricity generation or oil refining), and processes within those modules represent specific technologies or groups of technologies (e.g., individual power plants).
• Energy flows are calculated based on a specific sequence of modules; transmission and distribution are typically placed near the top (closest to demand), while primary resource extraction is placed at the bottom.
• The system distinguishes between three types of fuels in the transformation process: feedstock fuels (converted within the process), auxiliary fuels (used for subsidiary or own-use consumption), and output fuels (the results of the module's processes).
• Transformation calculations are driven by demand analysis results, where each module satisfies one set of fuel requirements while creating new input requirements, ultimately determining the total need for primary resources and imports.
