(MENAFN- The Rio Times) Brazil and Paraguay are quietly reopening one of South America's most valuable contracts: the deal that decides who really benefits from the Itaipu hydroelectric dam.

It sounds technical. It is actually about money, power and how far governments should go to defend their interests. Itaipu is a 14-gigawatt giant on the Paraná River. It provides almost all of Paraguay's electricity and a meaningful share of Brazil's.

On paper, each country has half the energy. In reality, Paraguay uses only a slice of its quota and is forced to sell the rest to Brazil at a cost-based price, not at what the market might pay.

For decades that price was dominated by the dam's construction debt. Those bills were finally paid off in 2023. That freed hundreds of millions of dollars a year.

Today Itaipu already sends around $600 million to Paraguay 's budget, a sizeable chunk for a small economy. If the new formula is more generous, the extra income could reshape the country's public finances for years.



This is where the story turns from engineering to politics. Earlier this year, talks over a new tariff collapsed after Brazilian court documents showed that Brazil's intelligence agency had hacked Paraguayan targets between 2022 and 2023, including people involved in the negotiations.

Paraguay called it a violation of sovereignty and froze the process. After months of damage control, Brazil has now delivered a confidential report and formal explanations.

Paraguay's foreign minister says the spying issue is closed. The two sides will sit down again in December to rewrite“Annex C”, the chapter that sets Itaipu 's financial rules.

Behind the polite communiqués, the choices are blunt. Brazil wants Itaipu to keep delivering cheap, predictable electricity to its industrial heartland and to households already squeezed by taxes and inflation.

Paraguay wants more cash for the energy it does not consume, more freedom to sell to other buyers and a contract that looks less like a one-way street.

For expats and foreign investors, Itaipu is a reminder that big infrastructure only works when contracts are respected, security agencies stay in their lane and neighbours settle disputes with numbers on paper, not games in the shadows.
