Track 7: Andean Flagship Sessions

Laguna Salinas ~10 MW Volcanic calderas. Active magmatic zone. Moqueg ua Calacoa - Putina ~108 MW Bulletin C58. Ticsani Volcano. Binary plants. Ccollo / Titire ~40 MW Associated with recent volcanism. Ubinas ~24 MW Limited by active volcanic risk of Ubinas. Tacna Casiri - Kallapuma ~135 MW Bulletin B 69. Reservoir Temperature (>150°C). Ancocollo ~120 MW 90% Estimation. Part of the Vilacota geothermal axis. Calientes ~100 MW Bulletin C 48. Priority A. High enthalpy fluids. Paucarani ~72 MW Bulletin B 63. Estimation (Monte Carlo). Kovire ~60 MW Report GE-38. Estimation with 83% certainty. Tutupaca 59 - 181 MW Bulletin C56. Variable range (Flash vs. Binary). Borateras ~40 - 50 MW Bulletin C47. System interconnected with Calientes field. TOTAL > 770 MW 4.2. 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 USD ($4.8M/MW), a ratio that would cover between 25-30% of Cerro Verde's base demand. The profiles (Figure 3) confirm geothermal superiority as a Base Load source. 134
