Tether Mining in Uruguay: Energy Conflict and the Collapse of Expansion
Behind the closure of Tether's mining project in Uruguay lies not just economic impracticality, but a sharp conflict with the state energy monopoly UTE. The dispute concerned the interpretation of contractual volumes of electricity supply, which ultimately led to a complete halt of the USDT issuer's operations in this South American country.
The Essence of the Dispute: Minimum Limit or Maximum Threshold?
The start of bitcoin mining in Uruguay came in 2023. Two sites in the Florida department, valued at $120 million, initially operated stably and generated profits. However, as energy consumption grew, disagreements arose. Tether interpreted the agreed volume of electricity as a baseline minimum, assuming its further increase. UTE, in turn, insisted that the specified capacity was a hard maximum.
The result was systematic shutdowns of the facilities, which sometimes lasted for several days. The parties tried to negotiate a new contract, but Tether representatives did not show up for a key meeting. The situation worsened after a change in UTE's leadership, following the inauguration of President Yamandú Orsi in March 2025. However, there is no direct evidence of a political subtext behind the project's failure — everything points to a purely commercial conflict.
Timeline of the Collapse: From Non-Payment to Disconnection
As early as May 2025, Tether's local legal entity — Microfin — stopped paying electricity bills. In June, the company officially notified about the termination of contracts. The culmination came on July 25, when UTE completely cut off power to both sites. By that time, the issuer's debt, according to local media, had reached $4.8 million. The formal closure and employee layoffs were only finalized in November.
Strategic Failure or Tactical Pause?
Uruguay was viewed by Tether as a testing ground for large-scale expansion in Brazil, Paraguay, and Argentina. The plans were ambitious: investments of up to $500 million, construction of three data centers with 165 MW capacity, and renewable generation facilities with 300 MW. However, this conflict demonstrates how fragile infrastructure projects can be in jurisdictions with state energy monopolies.
Despite the Uruguayan failure, Tether continues to expand its presence in mining. The company has already invested over $2 billion in energy infrastructure and manages 15 facilities in South America. Recently, the issuer also introduced its own open-source operating system for bitcoin mining.
My analysis: This case is a vivid example of how the regulatory and infrastructure environment can destroy even well-funded projects. For Tether, this is a painful but important lesson: in countries with state energy monopolies, legal risks and political instability must be built into the business model from the very start. The exit from Uruguay will not stop the expansion, but it will force a reassessment of the approach to choosing jurisdictions.
