Morocco launches tender for 1,000km power transmission line

Morocco’s National Office of Electricity and Potable Water (ONEE) has launched a prequalification process for contractors to build around 1,000km of ultra-high-voltage transmission lines linking Boujdour and Tensift, MAP reported. 

The project is a key part of Morocco’s strategy to support the national grid and expand renewable energy integration across the country. The lines are expected to enter service by December 2028.

The new transmission corridor will transport around 2,000MW of renewable electricity from the south to central regions. ONEE has set January 15, 2026, as the deadline for bid submissions, which will be opened immediately afterwards for evaluation. 

Following prequalification, shortlisted firms will be invited to submit full bids under an Engineering, Procurement and Construction (EPC) model, with the selected contractor responsible for design, construction and commissioning. The project complements broader transmission upgrades underway at ONEE, including a planned HVDC link connecting Morocco’s southern and central regions. 

ONEE’s network already spans more than 30,000km of very high-voltage lines, including a 400kV double-circuit line to Dakhla and another under construction, due to enter service in mid-2026. The latter will evacuate roughly 900MW from new wind farms scheduled for completion by the end of 2026.

Morocco targets the sourcing of 52% of national electricity from renewables by 2030, in line with King Mohammed VI’s long-term energy roadmap.
