Paraguay suspended negotiations with Brazil over Itaipu Dam energy tariffs after allegations of Brazilian intelligence hacking surfaced.
Paraguayan Foreign Minister Rubén Ramírez Lezcano announced the pause, demanding explanations from Brazil regarding alleged cyberattacks targeting Paraguayan government officials.
The Itaipu Dam, jointly managed by Brazil and Paraguay, is a vital energy source, supplying 88% of Paraguay’s electricity and 11% of Brazil’s. Annex C of the Itaipu Treaty, which governs financial terms, expired in 2023.
Both nations had aimed to finalize a new agreement by May 2025. However, reports claim Brazil’s Intelligence Agency (ABIN) accessed confidential Paraguayan data during tariff negotiations.
The alleged operation began under former President Jair Bolsonaro in June 2022 and reportedly continued into President Luiz Inácio Lula da Silva’s term.
ABIN allegedly hacked Paraguayan government systems via servers in Chile and Panama to extract sensitive information. Targets included Paraguay’s Senate, Chamber of Deputies, and Presidency.
Brazil denied any involvement under Lula’s administration, attributing the operation to Bolsonaro’s tenure. Officials claimed the operation ceased in March 2023 upon discovery by Lula’s team.
Despite this, Paraguay initiated an investigation and recalled its ambassador from Brazil for consultations. The controversy jeopardizes trust between the two nations, complicating future cooperation on Itaipu and broader regional partnerships.
Recent tariff negotiations had already proven contentious. Paraguay sought higher rates, proposing $20.75 per kilowatt-month, while Brazil aimed to maintain lower costs. A compromise set tariffs at $19.28 until 2026.
This scandal underscores the growing role of cybersecurity in international diplomacy and energy negotiations, raising questions about transparency and sovereignty in bilateral agreements.
