My detailed analysis of the circumstances surrounding the winding down of Tether's mining project in Uruguay shows that the official version citing "uncompetitive tariffs" is merely the tip of the iceberg. The root of the problem lies in a systemic conflict with the state energy monopoly UTE, which escalated into a legal and financial collapse.
The core of the dispute: contract interpretation
Having launched bitcoin mining in 2023 with two sites in the Florida department (total investments — $120 million), Tether faced a fundamental problem in interpreting the agreement. The USDT issuer viewed the agreed volume of electricity as a minimum threshold, planning to scale up. UTE, however, insisted that the specified capacity was a hard maximum. This legal collision led to regular outages lasting up to several days, paralyzing operations.
Failed negotiations and a change of power
The critical moment came with the collapse of a meeting: Tether representatives simply failed to show up for the agreement on a new contract, as recorded in the protocols. The situation worsened after President Yamandú Orsi took office in March 2025. The change in UTE's leadership hardened the state company's stance. Although there is no direct evidence of political undertones, it is clear that the new directors stopped making concessions to the private issuer.
Timeline of the collapse
Just two months after the government change, the local legal entity Microfin stopped paying its bills. In June 2025, notices of contract termination followed, and on July 25, UTE completely cut off power to the facilities. The finale came on November 25, when Tether officially notified labor authorities of mass layoffs. Meanwhile, the debt for energy and services reached $4.8 million — an amount that, for a company with billion-dollar reserves, looks more like a matter of principle than financial necessity.
Strategic context
Uruguay was supposed to be just a testing ground. According to former contractors, Tether planned expansion into Brazil, Paraguay, and Argentina with a total budget of up to $500 million, including three data centers with 165 MW and 300 MW of renewable energy generation. The failure in Uruguay is not a retreat from mining but a tactical withdrawal. CEO Paolo Ardoino confirmed in June 2025 investments of $2 billion and 15 sites across South America, and in early 2026, the company released an open operating system for bitcoin mining.
My conclusion: Tether's exit from Uruguay is a classic conflict between private capital and state infrastructure, where legal uncertainty in contracts became a deadly weapon. For the market, this is a signal: even the largest players are vulnerable to regulatory and political risks in Latin America, and betting on "renewable" energy without clear supply guarantees is a gamble. I expect that in Brazil and Paraguay, Tether will demand fundamentally different terms, including independent generation sources.
