BESS PERU - FREE SUMMARY R35 edition, October 27, 2026. Eleven business lines and power-plant reserve, industrial/mining peak reduction, isolated and temporary energy applications. Targeted base: 25 records, 24 cases and one grouping, not a census. Five reconciled COES codes and 240 evaluation records do not prove physical failures or annual availability. Majes/Repartición and mobile-energy extensions remain separate. Six decision profiles: offer comparison, integration/timing, O&M review, financing, supply contract and warranty. La Morena retains different savings windows; IFC corporate lending is not allocated wholly to BESS. Includes sources and own scenarios, not national monetary TAM, supplier ranking, certified permits or guaranteed returns. Future milestones are not presented as fulfilled.
