Editing Itaipu Dam (section)

=== Negotiations between Brazil and Paraguay ===
The concept behind the Itaipu Power Plant was the result of serious negotiations between the two countries during the 1960s. The "Ata do Iguaçu" (Iguaçu Act) was signed on July 22, 1966, by the Brazilian and Paraguayan Ministers of Foreign Affairs, [[Juracy Magalhães]] and [[Raúl Sapena Pastor]]. This was a joint declaration of the mutual interest in studying the exploitation of the hydro resources that the two countries shared in the section of the Paraná River starting from, and including, the ''Salto de Sete Quedas'', to the ''Iguaçu River'' watershed. The treaty that gave origin to the power plant was signed in 1973.

The terms of the treaty, which expired in 2023, have been the subject of widespread discontent in Paraguay. The government of President Lugo vowed to renegotiate the terms of the treaty with Brazil, which long remained hostile to any renegotiation.<ref>{{cite web|last=Nickson|first=Andrew|title=Paraguay: Lugo versus the Colorado Machine|work=Open Democracy|date=20 February 2008|url=http://www.opendemocracy.net/article/democracy_power/politics_protest/paraguay_fernando_lugo|access-date=3 August 2009|archive-url=https://web.archive.org/web/20090803073835/http://www.opendemocracy.net/article/democracy_power/politics_protest/paraguay_fernando_lugo|archive-date=3 August 2009|url-status=live}}</ref><ref>{{cite web|last=Mander|first=Benedict|title=Brazil's Itaipú dam treaty with Paraguay up for renewal|work=Financial Times|date=20 September 2017|url=https://www.ft.com/content/bf02af96-7eb8-11e7-ab01-a13271d1ee9c |archive-url=https://ghostarchive.org/archive/20221210/https://www.ft.com/content/bf02af96-7eb8-11e7-ab01-a13271d1ee9c |archive-date=2022-12-10 |url-access=subscription}}</ref>

In 2009, Brazil agreed to a fairer payment of electricity to Paraguay and also allowed Paraguay to sell excess power directly to Brazilian companies instead of solely through the Brazilian electricity monopoly.<ref>{{cite news|date=26 July 2009|url=http://news.bbc.co.uk/2/hi/americas/8169139.stm|title=Why Brazil gave way on Itaipu dam|access-date=2009-07-26|work=[[BBC]]|archive-url=https://web.archive.org/web/20090726101650/http://news.bbc.co.uk/2/hi/americas/8169139.stm|archive-date=26 July 2009|url-status=live}}</ref><ref>{{cite news|work=[[New York Times]]|first=Alexei|last=Barrionuevo|date=July 27, 2009|page=A10|url=https://www.nytimes.com/2009/07/27/world/americas/27paraguay.html|title=Energy Deal With Brazil Gives Boost to Paraguay|access-date=February 24, 2017|archive-url=https://web.archive.org/web/20170820035519/http://www.nytimes.com/2009/07/27/world/americas/27paraguay.html|archive-date=August 20, 2017|url-status=live}}</ref>
