Foundational Foresight, Flow & Factory Fusion

Nestled on an artificial island carved by a canal through the gentle bend of the Bacchiglione River, the Colzè hydroelectric plant is more than bricks, turbines and wires, it is the realisation of a bold vision set in motion over a century ago. In the early twentieth century, engineer Antonio Beltrame foresaw the transformative power of harnessing the river’s hydraulic drop to directly energise his steel mill. This idea became reality in 1937 when Colzè officially began operations, connected to the Vicenza facility by a dedicated power line. “This place marked the beginning of a pioneering path,” recalls Gianmaria Zanni, Energy Director at AFV Acciaierie Beltrame, highlighting how history and ambition came together at this very spot.

Tenacious Transformation, Turbulence & Triumph

The journey of Colzè has not been without its tests. Over the decades, the plant adapted to changing times through multiple upgrades, ensuring its machinery remained efficient & resilient. A major milestone arrived in 2010, when Colzè underwent significant modernisation aimed at improving capacity and reliability. Later that same year, however, nature posed a formidable challenge, a severe flood in November that swept across the region, threatening to derail operations. “It’s not just about rebuilding,” shares Zanni, “but about reimagining the future with each challenge.” Instead of retreating, Colzè emerged stronger, embodying resilience and foresight in equal measure.

Kilowatt Keepsakes, Kinetic Knowledge & Kindled Continuity

Today, Colzè operates with an installed capacity of about 800 kilowatts. This steady flow translates into an impressive annual output of around 3.5 million kilowatt-hours of renewable electricity. In real terms, that is enough to power more than 1,200 households every year—offering the local community a reliable source of green energy. Beyond figures, these numbers tell a deeper story: that an idea sparked by hydraulic ingenuity can still illuminate thousands of homes nearly nine decades later.

Sustainability Synergies, Steel & Streamlined Solutions

Colzè’s purpose reaches beyond producing electricity; it is woven into the industrial fabric of AFV Acciaierie Beltrame’s steel production. By converting the river’s natural kinetic energy into power, Colzè reduces reliance on external, often carbon-intensive energy sources. This synergy not only supports the steel mill but demonstrates a practical commitment to circularity, where production and sustainability can strengthen each other. As Zanni puts it, “Colzè proves that green energy and industrial activity don’t have to compete, they can complement each other beautifully.”

Resilient River, Regional Roots & Renewable Renaissance

Located in the province of Vicenza, Colzè has become a local symbol, rooted in the landscape and memory of the community. Its presence inspires broader awareness about renewable energy’s potential to preserve both economic vitality and environmental health. “It’s a tangible example of how tradition and innovation can coexist,” says Zanni. In an era dominated by debates on decarbonisation and energy transition, Colzè’s steady currents provide a reassuring reminder that history can inform the path forward.

Harmonious Heritage, Hydro & Human Hope

Colzè is not just a functional infrastructure asset; it embodies the philosophical harmony between human engineering and natural ecosystems. The plant’s design embraces the flow of the Bacchiglione River rather than obstructing it, illustrating how progress need not come at nature’s expense. As Zanni reflects, “This plant is part of who we are, it honours the past while helping us meet today’s sustainability challenges.”

Cleaner Currents, Cultural Continuity & Committed Course

For AFV Acciaierie Beltrame, Colzè is living proof that industrial vision can transcend decades, blending heritage with modern environmental commitment. Its enduring operation showcases that sustainability is not an isolated effort but a continuous journey rooted in choices made yesterday, refined today and guiding tomorrow. “Colzè is a symbol of local roots and a strong commitment to a cleaner energy future,” Zanni concludes, echoing the plant’s quiet yet powerful legacy.

Key Takeaways

• Colzè has been producing renewable energy since 1937, supplying around 3.5 million kWh annually.

• The plant powers over 1,200 homes and directly supports AFV Acciaierie Beltrame’s steel production.

• It stands as a model of resilience, industrial foresight & harmony between history and sustainability.
