Executive Summary

Tether, the issuer of the USDT stablecoin, has publicly refuted reports claiming its withdrawal from a $500 million crypto mining project in Uruguay. Local media reports alleged Tether's facilities were disconnected by the state-owned utility National Administration of Power Plants and Electric Transmissions (UTE) due to an outstanding $4.8 million electricity bill. Tether acknowledged a debt dispute and stated that its local operating company is actively engaged in negotiations with the Uruguayan government to resolve the issues and evaluate future development paths in the region.

The Event in Detail

Local Uruguayan news outlets, including Busqueda and Telemundo, reported that Tether's crypto mining operations were halted after UTE disconnected power. These reports indicated an unpaid electricity bill of approximately $2 million for May, along with an additional $2.8 million for other local projects, bringing the total alleged liability to $4.8 million, excluding potential fines and surcharges. The power interruption reportedly occurred on July 25. UTE confirmed the power shutdown, citing missed payments and the exhaustion of security deposits, which is a standard procedure for defaulting customers. In response, Tether, through comments to Cointelegraph, denied an exit from the region, stating, "We continue to evaluate the best way forward in Uruguay and the region more broadly. While reports have speculated an exit from the region, these do not accurately reflect the situation." The company confirmed that its local operating partner, Microfin, is in "ongoing discussions with the government to resolve the outstanding friction."

Financial Mechanics and Dispute Resolution

The dispute centers on approximately $4.8 million in alleged outstanding electricity bills and other local liabilities. Reports suggest that Tether's monthly electricity bill was around $2 million. UTE intervened after the debt exceeded the guarantee amount provided by the local operator. A Memorandum of Understanding (MoU) signed in June 2025 between UTE and Microfin aimed to resolve previous debt through regularized payments and tariff negotiations. However, unresolved arrears ultimately led to the July 25 power cut. Electricity costs in Uruguay are notably high for the Latin American region, ranging from $60 to $180 per megawatt-hour (MWh), in contrast to approximately $22 MWh in Paraguay, where Tether also operates. Energy expenses constitute a significant portion, up to 80%, of the operational costs for crypto mining ventures. The current negotiations between Microfin and the Uruguayan government are aimed at addressing these high costs and the outstanding debt to ensure a constructive path forward for Tether's long-term commitment to the region.

Business Strategy and Market Positioning

Tether announced plans to commence crypto mining in Uruguay in November 2023, projecting potential investments up to $500 million. The company's "Tether Energy" project positioned Uruguay as an attractive location due to its renewable energy infrastructure, with approximately 95% of its electricity generated from wind, solar, hydro, and biomass. This strategy aimed to align Tether with sustainable mining practices. However, the high operational costs in Uruguay, particularly for electricity, present a challenge compared to lower-cost regions like Paraguay. This situation underscores the critical balance between renewable energy sourcing and economic viability in large-scale crypto mining operations. The incident highlights the vulnerability of energy-intensive projects to local utility payment protocols and the necessity for robust financial discipline and contractual guarantees in regulated markets. Tether's broader strategy involves expanding beyond its core stablecoin operations into venture investments, having backed over 120 companies globally. This dispute, while specific to its mining arm, could indirectly influence perceptions of its operational diversification.

Broader Market Implications

The dispute between Tether's local operator and UTE in Uruguay highlights the significant impact of energy costs and regulatory frameworks on the profitability and stability of global crypto mining operations. This event may lead to increased scrutiny from other countries regarding the financial robustness of foreign investments in critical infrastructure, particularly in sectors with high energy demands like Web3 and AI. The challenges faced by Tether could influence investor sentiment regarding the operational stability of large-scale crypto ventures, especially those relying on specific regional energy policies. While Tether denied an exit, the public dispute and acknowledgement of ongoing negotiations could raise questions about transparency and operational efficiency, albeit indirectly, for a company that is also expanding its diversified business ventures beyond stablecoin issuance. The incident also serves as a case study on the risks associated with high electricity costs, even in regions committed to renewable energy, for energy-intensive industries.
