The end of Tether's bitcoin mining operations in Uruguay is not just a story about unprofitable tariffs, as was previously suggested. In the course of my own investigation, I found that the root of the problem lies in a systemic conflict between the USDT issuer and the state energy monopoly UTE, which escalated into a protracted legal and financial dispute.
The essence of the disagreement: contract interpretation
The project launched in 2023 with great fanfare: two sites in the Florida department with a total cost of $120 million. Initially, operations ran smoothly and were profitable. However, as energy consumption began to grow, the parties encountered a fundamental divergence in the interpretation of the contract. Tether insisted that the agreed volume of electricity was a minimum threshold that could be expanded. UTE, on the other hand, considered the fixed capacity to be a hard cap that must not be exceeded.
This legal conflict led to systematic shutdowns of the facilities, lasting up to several days. Negotiations on a new agreement reached a dead end: the issuer's representatives simply did not show up for a key meeting. The situation was exacerbated by a political factor — after the change of government in Uruguay in March 2025, UTE received new management that took a tougher stance. Although there is no direct evidence of political motives, in my analysis it is clear that the change in the management team removed the last opportunities for compromise.
Timeline of default and shutdowns
As early as May 2025, Tether's local legal entity, Microfin, stopped paying electricity bills. In June, the company officially notified of contract termination, and on July 25, UTE completely cut off power to both sites. The accumulated debt for energy and related services was estimated at approximately $4.8 million. The final point was set on November 25, when Tether notified labor authorities of mass employee layoffs.
Strategic context and my assessment
It is important to understand that Uruguay was viewed as a pilot site for large-scale expansion in Brazil, Paraguay, and Argentina. The plans were ambitious: up to $500 million in investments, three data centers at 165 MW, and 300 MW of renewable generation. The failure in Uruguay is a serious signal that even the largest players face infrastructure and regulatory risks in Latin America.
In my view, this decision does not indicate Tether's abandonment of mining as such — the company has still invested over $2 billion in energy infrastructure worldwide and released its own operating system for mining. However, the lesson here is obvious: in countries with state monopolies on energy resources, even the most capitalized stablecoin issuer can become a hostage to a bureaucratic interpretation of a contract. This is a classic example of how the inflexibility of an infrastructure partner can destroy even a well-funded project.
