LEAP Data Requirements

The document provides a comprehensive checklist of data requirements for users of the LEAP software, emphasizing that requirements vary based on whether a user chooses an aggregate top-down or disaggregated bottom-up approach. It details necessary inputs across demographic, macroeconomic, and energy sectors, including demand forecasting metrics and supply-side technical data. The guide notes that national energy balances are the most critical data source and suggests supplementing missing domestic data with international sources or estimates.

• LEAP's data requirements are flexible and depend on the model's scope; users can choose between an aggregate, top-down data set focusing on total fuel consumption by major sector, or a disaggregated, bottom-up data set that examines specific devices and end-uses within sub-sectors.
• National energy balances are identified as the most critical piece of information for the model, ideally including data on energy consumption by sector/sub-sector, energy conversion, statistical differences between supply and demand, and summaries of primary production, imports, exports, and stock changes.
• Demand forecasting in LEAP requires projections of activity levels and energy intensities. For transportation, this involves passenger-kms and tonne-kms split by mode and technology; for industry, it involves physical production measures (e.g., tonnes of cement) or economic value added by sector.
• Comprehensive energy supply modeling requires detailed technical and financial data for electric generation, including installed capacities in MW, historical generation in GWh, heat rates, capital and operating costs, seasonal load shapes, and transmission and distribution losses.
• For greenhouse gas (GHG) mitigation assessments, the guide suggests using IPCC "Tier 1" emission factors as a baseline, which can be replaced by more specific national emission factors for local power plants or vehicles when available.
