2264 3.3. Demand Projection Methodology Future demand of the Southern Node (2026-2046) was projected using the "Aggregated Scenarios" methodology. Total demand (DTotal) was calculated as the vector sum of inertial vegetative demand and discrete loads from new projects: 7PC>5H =7B27 +7-)$215 Where:Vegetative Demand (8´¨≠): Calculated from a 2026 base demand (~1,450 MW) with a compound annual growth rate (CAGR) of 3.2%. Block Loads (8ÆØ∞¨ô±): Discrete sum (Pi⋅δit) of power required by the entry of new projects (e.g., Zafranal, Tía María) and mining fleet electrification. 4. RESULTS 4.1. Resource Characterization and Energy Inventory in the Southern Volcanic Axis Analysis of regional potential, tectonically controlled by the Incapuquio and Cincha-Lluta fault systems, estimates an aggregate resource exceeding 770 MWe in high-enthalpy reservoirs (Table 4). Geophysical inversion models have delineated low resistivity anomalies (<10 ohm·m) and temperatures >200 °C in the Calientes and Borateras fields (Tacna), as well as Chocopata and Achumani (Arequipa). Likewise, specific studies in Calacoa (Moquegua) suggest proven reserves in the order of 100 MW, validating the effectiveness of AI-assisted predictive models for linking with mining demand.

Project Classification and Viability Analysis (Achumani Case) Based on data density, the Tacna Cluster (Calientes, Borateras) and Achumani Field are classified as Brownfield (Pre-feasibility). To validate the technical viability of the Arequipa Cluster, the Achumani Project (100 MW, First Stage) was analyzed. Estimated investment (CAPEX) amounts to ~$480 million
