In a groundbreaking policy change, Brazil has removed import tariffs on energy-efficient Bitcoin mining equipment. This decision, targeting hardware using SHA256 algorithms with performance over 200 terahashes per second and efficiency under 20 joules per terahash, is expected to significantly impact both the cryptocurrency and energy sectors. Within days, France’s state-owned energy giant Engie has begun evaluating Bitcoin mining at its vast 895-megawatt Assu Sol solar plant in northeastern Brazil, aiming to convert surplus energy into financial benefits, enhancing the plant’s profitability.
How Does Bitcoin Mining Reduce Energy Waste?
Brazil’s renewable energy capacity has soared, but with it, the problem of energy “curtailment”—unused surplus caused by transmission limitations. This is particularly acute in the northeast, where solar facilities face bottlenecks. Bitcoin mining presents an innovative solution, utilizing excess electricity that otherwise would be wasted, and converting it into revenue without additional strain on the power grid.
What Significance Does the Tariff Removal Hold?
The new regulation, Resolução GECEX 861, focuses exclusively on sophisticated ASIC technology that meets specific efficiency standards. With this exemption in place until 2028, companies can minimize upfront costs, facilitating large-scale, professional mining operations. Although other taxes remain, the lifting of customs duties represents a financial impetus for new investments.
In Brazil, Bitcoin mining viability is intricately tied to three main factors: equipment efficiency, Bitcoin’s market value, and electricity costs. Efficient machinery operating at 200 terahashes per second with sub-20 joules per terahash is breaking even at local electricity rates of around $0.071 per kWh. This scenario encourages miners to tap into unused energy from renewable sources.
Engie’s exploration into Bitcoin mining at its Assu Sol facility marks a pivotal venture among traditional energy firms in Brazil. This gradual initiative is anticipated to explore the technical feasibility of mining and may set a precedent for other energy companies. However, structural economic barriers, like high financing costs and potential regulatory changes, continue to pose challenges.

Investors must reconcile short-term opportunities with potential long-term uncertainties. Changes in energy transmission investments could alter curtailment rates, diminishing Bitcoin mining’s desirability among renewable sectors. Moreover, the expiration of the duty waiver post-2028 presents a looming uncertainty.
While the current tariff reduction eases the initial entry barrier, sustainable mining ventures will depend on securing reliable financing and energy sources. Ramp-ups from pilot programs to extensive development will rely heavily on technical and regulatory frameworks.
Brazil’s strategy, focused on advancing specific mining technologies, is distinct in selectively opening its energy markets for innovative financial gains. The course set by availability of cutting-edge hardware, evolving energy sectors, and proactive stakeholder involvement will shape Brazil’s crypto-energy landscape.
