Engie Pursues Bitcoin Mining at 895-MW Brazil Solar Plant
Engie is evaluating bitcoin mining as one option to absorb excess generation from its 895-megawatt Assu Sol solar plant in Brazil's northeast, which entered full commercial operation in February. The facility already faces grid-imposed curtailments that threaten revenue.
Key Takeaway
Engie's bitcoin mining plan signals renewable curtailment pain—but miners are already fleeing to AI.
French utility giant Engie is considering bitcoin mining at Assu Sol to soak up power the grid can't handle. Engie Brazil Country Manager Eduardo Sattamini told Reuters the company is looking at offtakers to absorb excess generation from the facility in Brazil's northeast. On-site battery storage and energy-intensive data centers for bitcoin mining are both on the table. Grid curtailments have already hit revenue—a problem that's cost Brazil's renewable sector billions of reais since 2023 as new capacity outstrips demand growth and transmission infrastructure lags.
Sattamini cautioned the bitcoin mining plan will take time, with implementation requiring a couple of years. Engie, which is 33.20 percent controlled by the French government, typically focuses on low-carbon energy transition. The company invested more than €3.8 billion in Brazil over the past six years and operates 10 gigawatts of fully renewable capacity after more than 25 years in the country.
The timing coincides with bitcoin miners pivoting hard into artificial intelligence as mining margins shrink. Bitfarms plans to wind down bitcoin mining through 2026–27 and convert its Washington State facility into an AI-ready GPU hub backed by a ₱7.38 billion ($128 million) upgrade deal. IREN locked in multibillion-dollar GPU cloud agreements with Microsoft. Bitdeer Technologies liquidated its entire corporate bitcoin treasury—from roughly 2,000 BTC at year-end 2025 to zero by February 20—and is rolling out NVIDIA GB200 NVL72 systems in Malaysia.
Data centers originally built for ASIC-powered SHA-256 hashing are being retrofitted to host high-performance GPUs for AI training and inference workloads. Strategy added 592 BTC in its 100th bitcoin purchase while miners abandon the asset class. Bitdeer sold 189.8 BTC during its latest reporting week before liquidating its remaining 943.1 BTC reserves by February 20, 2026.
