Bitcoin Mining Consumes 30% of Paraguay’s Power as Analysts Warn of 2029 Grid Crisis

Bitcoin mining operations in Paraguay have reached a scale that threatens the country’s energy security, according to analysts speaking at the “Accelerating Bitcoin” conference held in Asunción on August 12-13. Energy researcher Victorio Oxilia reported that mining activity now consumes approximately 30% of Paraguay’s total electricity, a volume comparable to the generation capacity of one and a half turbines at the Itaipú hydroelectric dam, one of the world’s largest power facilities.

The analysis points to 2029 as a critical inflection point when current generation sources may no longer meet demand, even under favorable hydrological conditions. Paraguay’s electricity grid relies almost entirely on hydropower from binational projects including Itaipú, Yacyretá and Acaray, but available capacity has remained largely stagnant while consumption accelerates. Maximum demand registered in January 2026 reached 5,752 MW against total available capacity of 7,678 MW, indicating the system already operates at approximately 75% utilization.

Mining contracts between Paraguayan utilities and mining companies expire in 2027, creating regulatory uncertainty around future electricity allocation. Authorities have not announced whether these agreements will be renewed or under what terms, adding another variable to an already constrained supply outlook.

Julio Fernández, head of the Center for Economic Studies at the Paraguayan Industrial Union, warned last year that rising consumption without corresponding capacity additions could trigger blackouts. The only major generation project currently under construction is Aña Cuá, which will add 135 megawatts of capacity, a figure analysts describe as insufficient against projected demand growth rates of 8% to 10% annually.

Energy analyst Cecilia Llamosas estimated Paraguay will require between $11 billion and $15 billion in investment over the next 13 years to close the supply gap, noting that virtually no new power infrastructure has been built in approximately 50 years. Llamosas distinguished bitcoin mining demand as more flexible than residential consumption because operators can adjust load in response to grid conditions, potentially providing some operational buffer during peak demand periods.

Paraguayan authorities have intensified enforcement against illegal electricity connections used by unlicensed mining operations, securing convictions in recent months as part of efforts to protect grid stability. The timing and severity of any future generation shortfall will depend on hydrological conditions, contract renewal decisions, investment execution and whether miners reduce consumption during constrained supply periods.
