Tensions between Argentina and Paraguay are rising after Paraguay stopped selling excess energy to Argentina from the Yacyretá hydroelectric plant.

This decision came after Argentina started collecting tolls from foreign ships on the Paraná River.

The toll became effective on January 1, 2023, but its impact grew in early September.

On September 18, Paraguay’s Vice President, Pedro Alliana, made the energy sales halt public.

Paraguay uses 15% of Yacyretá’s electricity, while Argentina bought the rest. Alliana said this move aims to protect Paraguay’s sovereignty.

He added that Argentina hasn’t acknowledged a $93 million debt related to Yacyretá.

Experts believe both nations will face economic fallout. Paraguay loses revenue by not selling its excess energy.

Legal analyst Hector Sosa Gennaro ties this issue back to the toll dispute on the Paraná River.

Santiago Peña, Paraguay’s President, warns that the issue is a political minefield. He suggests that strong interests on both sides make the situation complex.

Given its multifaceted nature, some doubt that international arbitration will resolve the issue.

Gennaro notes that Paraguay’s decision safeguards its sovereignty. However, he criticizes remarks from Sergio Massa, Argentina’s Economy Minister.

Massa claims Paraguay owes Argentina billions for Yacyretá’s construction in the 1980s and 1990s. Gennaro says such comments don’t help resolve the conflict.

Background

This tension isn’t just a bilateral issue; it also has regional implications. Both countries are members of Mercosur, a South American trade bloc.

So, unresolved tension could affect the bloc’s stability. Moreover, hydroelectric power is critical for both nations.

Argentina needs the energy for its industries, and Paraguay benefits from the revenue.

Trade plays a crucial role in the geopolitics of the region. A long-term fallout could entice either country to seek new partners.

This might divert attention away from regional integration, a cornerstone for Mercosur.

Paraguay’s energy surplus has always been a bargaining chip, now more prominent than ever.
