Tether’s $120 Million Bitcoin Mining Project in Uruguay Shut Down After Power Dispute

Tether’s $120 million Bitcoin mining investment in Uruguay has been disrupted after the country’s state-owned electricity utility cut power to the project’s mining sites, according to information shared by @coinbureau on X. The shutdown followed a dispute over unpaid electricity bills and a revised power contract, according to Reuters.

The interruption occurred in July 2025 and has effectively halted operations at the sites involved in Tether’s Bitcoin mining expansion in Uruguay. The project had been positioned as an important part of the company’s broader effort to expand cryptocurrency mining operations across South America.

The dispute highlights the challenges facing large-scale Bitcoin mining operations, where access to reliable and competitively priced electricity is a central component of the business.

Uruguay Utility Cuts Power to Mining Sites

Uruguay’s state-owned electricity provider, UTE, cut electricity supplies to Tether’s mining sites in July 2025, according to the information cited in the X post.

The decision followed a dispute involving unpaid power bills and changes to the electricity contract governing the mining operations.

Electricity represents one of the largest operating expenses for Bitcoin miners because specialized machines must run continuously to compete for block rewards. As a result, mining companies typically depend on long-term arrangements with electricity providers to secure predictable access to power.

A disagreement over billing and contract terms can therefore have an immediate impact on mining operations, particularly when a utility provider suspends electricity supplies.

The shutdown in Uruguay brought Tether’s operations at the affected sites to a halt and disrupted plans associated with the company’s regional mining expansion.

Tether Had Planned $120 Million Mining Investment

Tether had committed $120 million to its Bitcoin mining activities in Uruguay, according to the information shared by @coinbureau.

The investment formed part of the company’s broader strategy to expand its presence in Bitcoin mining. Uruguay was intended to serve as an important location within that regional strategy, with the project designed to contribute to Tether’s expansion across South America.

The company has increased its involvement in Bitcoin mining as part of a broader push into the digital asset infrastructure sector. Mining requires significant investments in specialized hardware, facilities and electricity, making the selection of suitable locations an important consideration for operators.

The interruption in Uruguay therefore affects more than an individual mining facility. It has disrupted a project that was expected to contribute to Tether’s wider regional mining ambitions.

Electricity Access Remains Critical for Bitcoin Mining

The dispute illustrates the importance of electricity arrangements for cryptocurrency mining companies.

Bitcoin mining involves specialized computing equipment that consumes substantial amounts of electricity. Miners must balance electricity costs against Bitcoin prices, mining difficulty and other operating expenses to maintain viable operations.

For large-scale projects, electricity contracts can determine the economic feasibility of an operation. Changes in pricing or contractual conditions can materially affect costs, while an interruption in power supply can prevent mining equipment from operating altogether.

In Uruguay, the disagreement between Tether and UTE ultimately resulted in electricity being cut to the affected sites. The development demonstrates how contractual and payment disputes can become significant operational risks for energy-intensive digital asset businesses.

Shutdown Disrupts South American Expansion Plans

The closure of the Uruguay sites represents a setback for Tether’s plans to establish a larger Bitcoin mining presence in South America.

The company’s $120 million investment was intended to support its expansion in the region, but the July 2025 power shutdown disrupted those operations.

According to the information attributed to Reuters, the dispute centered on unpaid electricity bills and a revised electricity contract. The X post did not provide further details regarding the amount of unpaid bills, the revised contractual terms or the duration of the shutdown.

The situation places the focus on Tether’s ability to resolve its disagreement with UTE and restore operations at the affected sites. For the wider Bitcoin mining industry, the case also underscores the importance of stable electricity agreements as miners expand into new markets.
