ONEE launches prequalification for 1,000 km of UHV power lines between Boujdour and Tensift

As part of its strategy to strengthen the national transmission network and support Morocco’s energy transition, the National Office of Electricity and Drinking Water (ONEE) has launched a prequalification notice for the construction of about 1,000 km of ultra‑high‑voltage alternating current (UHVAC) power lines linking Boujdour and Tensift.

The project is part of a set of major electrical infrastructures led by ONEE, including a future high‑voltage direct current (HVDC) link under development to connect southern Morocco with the centre of the Kingdom, the office said.

The ultra‑high‑voltage lines, due to be operational by December 2028, are designed to carry about 2,000 MW of renewable power, meeting rising national demand and enabling large‑scale integration of renewables.

Following the prequalification phase, ONEE will select contractors to take part in the tender’s second stage. The project will follow the EPC scheme (engineering, procurement and construction), with the chosen contractor responsible for design, construction and commissioning under a turnkey contract.

The deadline for submitting bids is set for January 15, 2026, at 12 p.m. (Moroccan time). The bid opening will take place on the same date. The pre-qualification notice can be downloaded from the ONEE website.

Morocco’s electricity network currently totals more than 30,000 km of very high‑voltage lines, including a 400 kV double‑circuit line reaching Dakhla.

Another 400 kV double‑circuit line is under construction, with commissioning due mid‑2026. It will evacuate about 900 MW, mainly from new wind farms expected to be operational by the end of 2026.

The future ultra‑high‑voltage Boujdour‑Tensift link will carry new renewable power from southern Morocco to the centre, ensuring integration into the national grid and strengthening supply security.

The project, in line with the national momentum driven by King Mohammed VI’s vision for strategic energy infrastructure, reaffirms ONEE’s commitment to sustainable development and a secure, reliable and decarbonised electricity supply.
