Exergy ORC to Revamp Ribeira Grande Geothermal Power Plant in the Azores

In a landmark move for clean energy in the Azores, Exergy ORC has secured a contract to revamp the Ribeira Grande geothermal power plant on São Miguel Island. 

This pivotal project is being undertaken in collaboration with EDA Renováveis, and it marks Exergy's second geothermal venture in the region—reinforcing its commitment to advancing the energy transition during what is now widely regarded as the "Geothermal Decade."
A Tailor-Made Solution for a Sustainable Future
As part of the modernization, two outdated geothermal units will be replaced with a state-of-the-art, 5 MW Organic Rankine Cycle (ORC) system. This advanced solution has been specifically designed to enhance the performance and efficiency of the Ribeira Grande plant, utilizing geothermal resources more effectively and sustainably.
The goal is not just to boost energy output, but to support São Miguel’s broader ambition: to run entirely on renewable energy. With the integration of Exergy's innovative ORC system, the island takes a major leap toward a fully decarbonized energy model—setting an inspiring example for island communities worldwide.
The Geothermal Decade: A Global Vision in Action
This project is part of a broader movement championed by Exergy and other clean energy leaders—an international push to significantly expand the role of geothermal power over the next ten years. The “Geothermal Decade” emphasizes the vital importance of clean, reliable, and baseload renewable energy systems, of which geothermal is a cornerstone.
Exergy’s continued presence and innovation in the Azores reflect the company's expanding global footprint. From Europe to the Americas, Exergy is actively contributing to the growth of geothermal technologies, making clean energy more accessible and sustainable in diverse environments.
A Shout-Out to the Team
Behind this project is a dedicated team of professionals who made it happen. Special recognition goes to Giacomo Menghetti, Exergy’s Sales Manager, whose efforts were instrumental in securing and shaping the vision of this collaboration. His leadership, combined with the hard work of the entire team, underscores the spirit of innovation and commitment that defines Exergy’s approach to every project.
Looking Ahead
A detailed press release is expected soon, outlining the technical specifications, performance expectations, and project timeline for the revamped Ribeira Grande facility. As the world increasingly looks toward clean energy, projects like this demonstrate that the geothermal sector is not only viable—it’s thriving.

Exergy ORC continues to lead by example, showing that innovation, partnership, and strategic investment can pave the way for a cleaner, more resilient energy future.


Conclusion

The Ribeira Grande geothermal project is more than just an infrastructure upgrade. It represents a bold, forward-thinking step toward energy independence and climate responsibility. As Exergy ORC continues to advance the frontiers of geothermal technology, it also empowers communities—like those in the Azores—to take control of their energy futures in sustainable and locally-driven ways.
Stay tuned for more updates as this transformative project unfolds.

Driving the UK Toward Net Zero: Chris Sladen on Geothermal’s Untapped Potential

Alphaxioms, we talked to Chris Sladen about his involvement in geothermal both in the UK, and globally By:  Robert Buluma Chris, please begin by explaining a little about yourself, and why you have a passion for geothermal? I have spent over 45 years involved in energy. Following undergraduate studies in geology at Southampton University, and a PhD in sedimentology at Reading University, I joined the energy sector in Aberdeen in 1980. It was a fascinating era when it seemed like at least one giant oil & gas field was discovered offshore every month; the wealth creation for the UK was gigantic. I got to see so much geology and rocks - my true passion. I moved to China in late 1983; not today’s China, this was over 40 years ago, a country closed for decades and embarking on an open-door policy, in part to bring both investment and technology. I became very interested in energy trends, energy politics, and new geography created by changing politics leading to opportunities for ene...

Unlocking Geothermal Power: Subsurface Secrets of Mount Erciyes Revealed”

Mount Erciyes: A Hidden Geothermal Treasure Beneath Cappadocia By: Robert Buluma Beneath the snow-capped slopes of Mount Erciyes , central Turkey’s highest peak, lies more than just volcanic history  it harbors the promise of geothermal energy . A new study published in the Journal of Volcanology and Geothermal Research has mapped the subsurface of Erciyes using three-dimensional magnetotelluric (MT) imaging , revealing zones of high electrical conductivity that point to heat, fluids, and possible magma bodies deep underground. Cracking the Code Beneath the Mountain Researchers led by S.B. Tank used advanced MT techniques to peer beneath Erciyes and its surroundings. Their results uncovered conductivity anomalies   regions where electricity flows more easily due to the presence of saline fluids, hot water, or partially molten rock . For geothermal experts, these anomalies are gold. They act as subsurface fingerprints of geothermal reservoirs , highlighting where heat ...
