Following a technical downtime in February 2024, the Noor Ouarzazate III solar power station has resumed operations. Established in 2018, this site utilizes concentrated solar power (CSP) technology through arrays of heliostats directing light onto a central tower. The use of thermal storage with molten salts heated to temperatures as high as 565°C enables the plant to produce energy well past nightfall.
The shutdown occurred due to a leak in the hot molten salt tank—a crucial part of the system. This issue, which stemmed from considerable thermal and mechanical stresses, necessitated an intricate and technically sophisticated resolution.
The resumption was conducted entirely in accordance with safety regulations, leveraging the knowledge of MASEN and its collaborators. Specific fixes, comprehensive examinations, and meticulous preparation enabled the safe recommencement of activities.
To enhance long-term reliability, construction is underway on a second, redesigned tank that will reinforce the plant’s infrastructure and improve its resilience.
Noor Ouarzazate III is once again playing a role in Morocco’s renewable energy output, aligning with the country’s national energy strategy that was initiated in 2009.
This restart underscores the commitment and skill of our teams,” stated Tarik Ameziane Moufaddal, CEO of MASEN. “Despite facing a challenging technical scenario, we addressed it with meticulousness, accountability, and strict adherence to global standards.
