Summary
The Madeira River basin, one of the main tributaries of the Amazon River, holds significant strategic importance for the Brazilian Interconnected Power System (SIN) due to its high hydroelectric potential. The basin hosts two major run-of-river plants, Santo Antônio HPP and

In 2023 and 2024, extreme drought and low inflows conditions were observed in the Madeira
River basin, leading to the total shutdown of Santo Antônio HPP’s generating units in 2023 and partial shutdown in 2024, also affecting Jirau HPP’s generation availability.
In this context, this paper presents the operational configurations analyzed and the dynamic security assessments studies conducted by the Brazilian System Operator (ONS) to define the transmission limits in the region to ensure a secure and reliable supply to the Acre and Rondônia
(AC/RO) subsystem during the periods of extreme drought. It also presents real time verified data with each associated risk that occurred between September and November 2024.
