New Structure Replaces Century-Old Dam in the Alps with Sustainable Technology and High Precision, But There Is No Partnership with Brazil at the Moment

The Spittallam Dam in the Swiss Alps was officially completed in May 2025 after six years of work under snow, ice, and significant engineering challenges. The project, 100% Swiss, replaces a structure from 1932 that showed cracks and structural risks, and is already seen as a global example of sustainability and hydropower efficiency.

Despite rumors on social media, there is no confirmation of a partnership between Brazil and Switzerland regarding the Spittallam Dam. The project, however, has been studied by experts and engineering enthusiasts in Brazil as a potential inspiration for modernizing our older hydropower plants, such as Tucuruí and Paulo Afonso.

Precision Engineering at 1,900 Meters Above Sea Level

Technology of the new Swiss dam can revolutionize old hydropower plants in Brazil

The Spitallamm Dam is located on Lake Grimsel, nearly 2,000 meters above sea level. Built with roller-compacted concrete (RCC), the new structure maintains the original dam’s height of 113 meters but now offers an estimated durability of over 100 years.

No Partnership with Brazil, But Clear Lessons

Several videos on YouTube and posts on X (formerly Twitter) fueled speculation that Brazil would participate in the Spittallam Dam. However, no official Swiss or Brazilian source confirms any bilateral partnership in this project. The Swiss Embassy in Brazil and technical reports only mention scientific and environmental cooperation in other sectors, such as at COP30.

The Brazilian interest appears to be more related to technical inspiration than direct cooperation. The RCC technology used in Spitallamm, for example, could be useful in renovating older national dams, as identified by the Ministry of Mines and Energy in a 2024 report.

Comparison with Itaipu and Belo Monte

Although much smaller in scale, the Spitallamm Dam stands out for its technical precision, sustainability, and low environmental impact, unlike Brazilian projects like Belo Monte, which displaced entire populations and face criticism to this day.

For comparison purposes:

Project	Annual Production	Environmental Impact
Spitallamm	1,500 GWh	Minimal, no inhabited area
Itaipu	103,000 GWh	Flooding of 1,350 km²
Belo Monte	39,000 GWh	Displacement of Indigenous people

These differences show how localized and sustainable solutions can be effective, especially in remote areas.

For you, Brazilian, what does this project say about our energy future? Should we invest more in modernizing dams or in new sustainable projects like this? Share your thoughts in the comments.
