Transformation Analysis

This guide describes the 'Transformation analysis' functionality within the LEAP software, which simulates the conversion and transportation of energy from primary resource extraction and imports to final consumption.

• Transformation analysis simulates the entire energy chain from the extraction of primary resources and imported fuels to final fuel consumption, allowing for alternative scenarios based on different policy and technology assumptions.
• The model structure is hierarchical: Transformation branches contain modules (representing energy conversion sectors like electricity generation or oil refining), and modules contain processes (representing individual technologies or groups of technologies).
• Processes are defined by specific technical and financial data, including capacities, efficiencies, capacity factors, and capital and operating and maintenance costs. They utilize feedstock fuels for conversion and optional auxiliary fuels for subsidiary or own-use energy consumption.
• The sequence of modules in the model tree is critical as it reflects the flow of energy; typically, transmission and distribution are placed near the top (closest to Demand), conversion modules in the middle, and primary resource extraction at the bottom.
• Transformation calculations are driven by Demand analysis results, where succeeding modules satisfy one set of fuel requirements while creating new input requirements, ultimately resulting in total requirements for imports and primary resources.
