In May of odd years, RIAC organizes the biannual Ibero-American Regional Encounter of CIGRE - ERIAC, in the region called “The Triple Frontier”, a tri-border area of Argentina, Brazil, and Paraguay, on a rotating basis among these three countries.

During the ERIAC, sessions are held by the 16 “mirror” National Study Committees of the Region, in which the articles approved by the Technical Committee of the event are presented by the authors and debated by the participants.

In 2023, the Brazilian National Committee of CIGRE was again responsible for promoting the XIX ERIAC, an edition that was not held in 2021 due to the restrictions arising from the global health crisis.

Embracing the challenge and, together with the ever-important partnership of Itaipu Binacional, the event took place from May 21 to 25, 2023, at the Rafain Palace Hotel & Convention Center, in the city of Foz do Iguaçu, Paraná, Brazil.
