Bitcoin in the Bush: Crypto Mining Powers Rural Zambia
Exploring the Intersection of Cryptocurrency and Renewable Energy
In the remote northwestern region of Zambia, where the mighty Zambezi River crashes down through rocky rapids, a unique venture is simultaneously transforming the local economy and harnessing renewable energy. Here, the roar of the river is complemented by the high-pitched whine of bitcoin mining computers, creating an unconventional yet potent partnership between cryptocurrency mining and hydroelectric power.
A New Model for Energy Production
Philip Walton, a representative of the company Gridless, asserts, “It’s the sound of money!” as he checks on a bitcoin mining operation housed within a shipping container. With about 120 computers continuously performing intricate calculations to verify bitcoin transactions, the mine is strategically located near the Zambezi river, directly linked to a hydroelectric plant that converts the river’s torrent into clean electricity.
The unique setup allows Gridless to capitalize on inexpensive energy—a crucial factor in making bitcoin mining economically viable. Walton explains that their partnership with the local energy provider includes a revenue-sharing model that benefits both parties. Even as bitcoin prices fluctuate, with current values hovering around $80,000 per coin, these operations remain profitable due to the steady supply of low-cost electricity.
Meeting Local Needs
The Zengamina hydroelectric power station, which became operational in the late 2000s, was initially designed to serve the local community, powering a hospital and eventually providing electricity for approximately 15,000 locals. However, the plant struggled to meet its financial obligations due to a slow adoption of services by residents.
The partnership with Gridless has been a game-changer. Daniel Rea, who oversees the hydro facility, notes that they were previously wasting half of their energy production. The integration of bitcoin mining has generated about 30% of the plant’s revenue, allowing them to keep rates low for the community. “Every day we were wasting over half of the energy we could generate,” Rea explains, highlighting how the mine’s establishment has significantly enhanced the facility’s sustainability.
Transformation in Daily Life
While cryptocurrency and mining may be foreign concepts to the townspeople of Zengamina, the access to electricity has brought significant changes to their daily lives. Local barber Damian, who only recently gained access to power, expresses his gratitude: “Getting power has changed my life…. The money I’m earning is helping me pay for school fees again.” His shop, vibrant with lights and music videos, serves as a gathering place for youth, showcasing the newfound vibrancy in the community.
For many locals, such as sisters Tumba and Lucy Machayi, the introduction of electricity has transformed their lifestyle. “Electricity completely changed the lives of people here,” Lucy notes, mentioning the ability to charge cell phones and connect with wider networks. Their experiences illustrate the contrast between their past in “the bush” and their current reality filled with modern conveniences.
Future Plans and Challenges
As Gridless contemplates the future, executives acknowledge that the partnership with Zengamina Hydro may soon evolve. The facility is on the verge of expanding its operations and connecting to the national grid, which could hinder the profitability of bitcoin mining at this location. However, Walton and his team remain optimistic, viewing this as a sign of success rather than an obstacle.
The company aims to replicate this model across Africa, seeking out locations with "stranded energy"—unused or inefficiently utilized power resources. Co-founder Janet Maingi indicates a bold vision for the future, actively raising funds to construct new hydro-plants and expand access to electricity in underserved rural regions.
Despite facing criticism from various stakeholders who regard bitcoin as an energy-intensive endeavor, Gridless maintains that their operations will prioritize local community energy needs. They argue that the financial incentives fostered through bitcoin mining can ultimately support the very communities that house their operations.
Conclusion
As the bitcoin mining operation in Zengamina illustrates, innovative solutions can emerge when renewable energy meets advanced technology. With a commitment to enhancing local economies while addressing and improving energy production, the integration of cryptocurrency mining in Zambia offers a glimpse of a promising, electrified future. The journey ahead for Gridless—and the communities benefiting from these initiatives—promises to be both transformative and impactful in the pursuit of sustainable energy access.
