GenCost 2025-26 Consultation Draft

This document is a consultation draft for GenCost 2025-26, authored by Paul Graham and Jenny Hayward, published by Australia's National Science Agency, CSIRO. It outlines the scope of the GenCost project and provides a detailed analysis of current technology costs, including capital costs for various generation and storage technologies. The document includes scenario narratives and data assumptions that inform projections of future costs. It presents results related to inflationary pressures and changes in the global generation mix, as well as a comprehensive analysis of the levelized cost of electricity (LCOE). The draft also discusses the methodology for estimating costs associated with high variable renewable energy (VRE) shares and includes estimates for both short-term and long-term projections. Additionally, it provides data tables and addresses frequently asked questions regarding technology inclusion principles and assumptions used in the analysis.
