ONEE Launches Pre-Qualification for Ultra-High Voltage Power Lines Between Boujdour and Tensift

Introduction to the UHT Transmission Line Project

The National Office of Electricity and Drinking Water (ONEE) has initiated a pre-qualification process for contractors interested in constructing new ultra-high-voltage alternating current (UHT) transmission lines. These lines, spanning approximately 1,000 kilometers, will connect the Boujdour and Tensift regions, enabling the efficient transport of electricity over long distances.

This project is a key component of ONEE’s broader strategy to enhance the national electricity transmission network and support Morocco’s energy transition. It is part of a comprehensive portfolio of major electrical infrastructure projects that include both operational, under-construction, and developing initiatives led by the Office.

Strategic Importance of the Project

Among the notable projects within this portfolio is the future high-voltage direct current (HVDC) link, which is currently being developed to directly connect southern Morocco to the central regions. This initiative underscores the importance of strengthening the country's electrical grid to accommodate growing energy demands and renewable energy integration.

The UHT line, expected to be commissioned by December 2028, is designed to carry around 2,000 MW of renewable electricity. This capacity will significantly contribute to the nation’s goal of increasing its reliance on sustainable energy sources.

Process and Timeline

Following the pre-qualification stage, ONEE will shortlist companies to participate in the second phase, which involves an official tender process. The project will be executed under an EPC (engineering, procurement, and construction) contract model. The selected contractor will oversee the entire project lifecycle, including design, construction, and commissioning, under a turnkey arrangement.

The deadline for submitting applications is set for January 15, 2026, at 12:00 PM (Moroccan time). On the same day, the bid opening will take place, marking the next step in the selection process.

Key Details of the Tender Process

• Pre-qualification Stage: Contractors are invited to submit their applications.
• Shortlisting: ONEE will select qualified companies for the tender process.
• Tender Process: A formal bidding procedure will be conducted.
• Contract Model: EPC (engineering, procurement, and construction).
• Project Execution: Turnkey arrangement for design, construction, and commissioning.
• Deadline: January 15, 2026, at 12:00 PM (Moroccan time).
• Bid Opening: Occurs on the same day as the deadline.

Future Implications

The successful completion of this project will not only improve the reliability and efficiency of Morocco's electricity transmission system but also support the country's efforts to meet its renewable energy targets. By enhancing the grid's capacity to transport electricity from renewable sources, the UHT transmission lines will play a crucial role in facilitating the transition to a more sustainable energy future.

Moreover, this initiative reflects the commitment of ONEE to invest in modern infrastructure that meets the evolving needs of the national energy sector. As Morocco continues to expand its renewable energy capacity, such projects will be essential in ensuring that the generated power can be effectively distributed across the country.

Conclusion

The pre-qualification call for the UHT transmission line project marks a significant milestone in Morocco's energy development. With a focus on sustainability, efficiency, and long-term planning, this initiative aligns with the nation's broader goals of achieving energy security and reducing carbon emissions. The upcoming tender process will determine the contractors who will bring this critical infrastructure to life, setting the stage for a more resilient and environmentally friendly energy network.
