In brief
In a remote area of Zambia, a bitcoin mine is leveraging excess hydroelectricity to generate profits while also providing sustainable energy to the local community, showcasing a unique partnership that benefits both sides.
The roar of the Zambezi River drowns out most sounds in the dense Zambian bush, but there's an unusual sound cutting through the noise—the whir of computer fans from a bitcoin mining operation. Operated by a Kenyan company, Gridless, this remote bitcoin mine has emerged as a significant player in both the cryptocurrency market and in enhancing local electricity availability.In an area near the border with the Democratic Republic of the Congo, Phillip Walton, an engineer for Gridless, oversees a shipping container filled with 120 bitcoin mining computers. The operation's proximity to the Zambezi River allows the team to tap into a hydroelectric power source, making their energy costs extraordinarily low—about $5 per day per machine, with profitability sustained even when bitcoin's value fluctuates.The Zengamina hydroelectric plant, established with local fundraising efforts, supports approximately 15,000 people. Its initial purpose was to power a local hospital, but it struggled to find sustainable customers until Gridless's arrival. The bitcoin mine now accounts for about 30% of the plant's revenue, reinvigorating the local economy.Many residents of Zengamina are unaware of the intricate financial workings of the bitcoin mine; instead, they are focused on the immediate benefits. Local businesses, like a barber shop, have flourished since power became widely available—transforming the town from a bush enclave into a hub of activity.Several young residents, such as sisters Tumba and Lucy Machayi, reflect on the dramatic changes electricity has brought, allowing them to stay connected via mobile phones and access entertainment. They acknowledge that they have benefitted from the hydroelectric project, even if the mechanics of bitcoin mining are beyond their understanding.While Gridless's time in Zengamina may be temporary as the hydroelectric plant connects to the national grid for increased efficiency, the company is looking to replicate this model. They are raising funds to build new hydroelectric facilities specifically for bitcoin mining in other areas of Africa, emphasizing the benefits of harnessing renewable energy for both local economies and the cryptocurrency industry.Their model, however, faces skepticism. Critics argue that bitcoin mining consumes too much energy at the expense of local communities, a concern heightened by past mining booms in regions like Kazakhstan and the U.S. Gridless insists that their approach aims not only to profit from bitcoin but also to empower local communities through sustainable energy solutions.As bitcoin mining continues to evolve within Africa's energy landscape, Gridless's partnership with Zengamina illuminates the potential for innovation to foster economic development—one computer at a time.
