The dispute surrounding the closure of Tether's Bitcoin mining project in Uruguay has revealed far deeper contradictions than a simple change in tariff policy. The key trigger was a protracted dispute with the state energy monopoly UTE over the interpretation of the electricity supply contract terms. This is a classic example of how infrastructure projects in Latin America encounter bureaucratic rigidity and inflexibility from local regulators.
The Core of the Conflict: Limits vs. Needs
Having launched mining operations in 2023 with two sites in the Florida department (total investment — $120 million), Tether initially demonstrated stable operational performance and profitability. However, as energy consumption scaled up, a fundamental difference in contract interpretation emerged. The USDT issuer viewed the agreed-upon electricity volume as a minimum threshold, anticipating its increase as the project grew. UTE, on the other hand, considered this figure an absolute maximum.
The result was systematic power outages lasting up to several days, which paralyzed equipment operations. Negotiation attempts failed: Tether representatives did not show up for the scheduled meeting, as confirmed by internal protocols. The situation worsened after the political rotation in March 2025, when the new government of Yamandú Orsi appointed fresh directors to UTE. However, there is no direct evidence that the project fell victim specifically to political changes.
Timeline of the Collapse
The escalation was rapid. Within just two months of the change in government, Tether's local legal entity — Microfin — stopped paying its bills. In June 2025, the company officially notified of contract termination, and on July 25, the energy company completely cut off power to both sites. By November, Tether announced the cessation of operations and mass layoffs. The accumulated debt for electricity and related services was estimated at $4.8 million.
Strategic Context
Uruguay was viewed as a testing ground before large-scale expansion in Brazil, Paraguay, and Argentina. The ambitions were colossal: up to $500 million in investments, including three data centers with 165 MW and 300 MW of renewable generation. The failure of the project in Uruguay is not just a local setback but a signal of systemic risks for Tether's entire South American strategy.
Nevertheless, mining remains a priority for the company. CEO Paolo Ardoino, back in June 2025, predicted Tether's leadership in this sector, estimating investments in energy infrastructure at over $2 billion and stating there were 15 sites in the region. The recent release of an open operating system for Bitcoin mining confirms that the company is not abandoning its plans but merely revising the geography.
My analysis: This case demonstrates the critical importance of legal precision in energy supply contracts. In emerging markets where state monopolies wield political influence, even major players like Tether find themselves hostage to bureaucratic interpretations. The lesson is simple: before investing hundreds of millions in infrastructure, it is necessary to secure not just a contract but guarantees at the government level. Otherwise, any political shift can nullify all efforts.
