Tether, the company behind the leading stablecoin USDT, has unexpectedly halted its $500 million Bitcoin mining initiative in Uruguay. The decision comes as a result of rising energy expenses and electricity rates that made the venture financially unsustainable. Tether confirmed to Cointelegraph that it has stopped mining operations and laid off 30 staff members, a significant shift for a project once considered a benchmark for sustainable cryptocurrency mining.
This development highlights the financial risks associated with large-scale crypto mining in areas where energy costs are unpredictable.
Launched in May 2023, Tether’s Uruguay operation was promoted as a strategic move to capitalize on the country’s renewable energy resources. Paolo Ardoino, who served as CTO at the time and is now CEO, stressed the project’s commitment to environmental sustainability, pointing to Uruguay’s plentiful solar and wind energy. The company planned to invest $500 million, including building three data centers and a 300 MW renewable energy facility. However, as energy prices soared and disagreements arose with Uruguay’s state-run utility UTE, the project became economically untenable.
By September 2024, local news outlets reported that Tether had defaulted on a $2 million electricity payment to UTE and owed an additional $2.8 million for other initiatives, bringing total outstanding debts to $4.8 million. Although Tether initially denied intentions to withdraw from Uruguay, it later acknowledged the project’s suspension, citing increased operational expenses and regulatory obstacles. Experts believe that Tether’s inability to negotiate favorable electricity tariffs for high-voltage power contributed to mounting financial strain.
Tether’s withdrawal from Uruguay illustrates the broader difficulties faced by cryptocurrency miners in regions with fluctuating energy prices. Reports from El Observador indicate that Tether invested at least $100 million in mining hardware and another $50 million in infrastructure. Despite these significant expenditures, a company representative stated that Tether remains interested in exploring opportunities in Latin America, especially those involving renewable energy, as reported by Cointelegraph. Nevertheless, the Uruguay experience serves as a warning for companies considering large-scale mining operations in markets with unstable energy policies.
The closure of Tether’s mining project has prompted questions about Uruguay’s ability to attract digital infrastructure investments. While the government has previously promoted the nation as a leader in green energy and technological advancement, Tether’s exit underscores the challenges posed by high electricity tariffs and regulatory ambiguity. As Tether considers alternative approaches for future projects, this episode highlights the complex relationship between ambitious crypto ventures and local energy economics.
