Morocco-UK Power Project, Morocco

The Morocco-UK power project is expected to supply 3.6GW of clean energy from Morocco to the UK.

The Morocco-UK power project is an integrated power generation, storage and transmission project proposed to be developed by Xlinks, a UK-based energy start-up focused on supplying low-cost wind and solar power from Morocco to the UK.

The project is planned to be developed without subsidy from the UK Government. It will connect the UK National Grid to renewable power generated in Morocco, through 3,800km of high-voltage direct current (HVDC) subsea cables.

The interconnector project will leverage high solar irradiance in south Morocco along with the North African country’s consistent convection desert winds to support the UK’s power needs when domestic renewable energy generation dips due to climatic conditions, such as slow winds.

Morocco-UK power project make-up

The power generation facility, comprising a solar and wind farm, will be developed on an area of 1,500km² in the Guelmim Oued Noun region of Morocco.

The combined facility will generate 10.5GW of energy, of which 3.6GW is planned to be transmitted to the UK to meet up to 8% of its electricity demand.

A 20GWh/5GW battery storage facility will also be built on-site, as part of the project, to store and deliver reliable energy to the UK when required.

The project will also involve the construction of new converter stations at both ends of the Morocco-UK HVDC interconnector.

The converter station at the Morocco end will convert the electricity generated from wind and solar resources from high-voltage alternating current (HVAC) to HVDC.

A converter station in Devon, UK, will convert the exported electricity back from HVDC to HVAC before feeding it into the British transmission network.

Transmission route details

The power transmission between Morocco and the UK will take place through onshore and subsea cables.

Four subsea cables, each measuring 3,800km long, will be laid to provide exclusive connection to the UK. Upon completion, these cables will be the longest subsea power cables in the world.

The cables will be buried at depths between 100m and 250m for most of the route. The maximum depth of the interconnector is expected to be approximately 700m.

The cable will take a subsea route from north-west of the city of Tantan, Morocco, up the Strait of Gibraltar, and along the coasts of Portugal, Spain and France, before going around the isles of Scilly off the coast of Cornwall, UK. It will pass through the exclusive waters of the UK and make landfall at Devon.

Grid connection

Xlinks has reached an agreement with the National Grid for two 1.8GW connections at Alverdiscott in Devon, England.

The first 1.8GW system of the HVDC interconnector project is expected to be connected to the UK’s electricity network by 2027.

Cable manufacturing and laying

Xlinks has established a cable manufacturing company, called XLCC, to supply the cable required for the Morocco-UK power project.

XLCC plans to establish cable manufacturing factories in Hunterston, Scotland; Port Talbot, Wales; and the north-east of England.

The cables will be manufactured with aluminium conductors and insulation made of cross-linked polyethylene (XLPE).

XLCC completed the design of a cable-laying vessel for the project in March 2022.

A shipyard will be selected to build the vessel by the end of the second quarter (Q2) of 2022, with the vessel’s delivery expected in the first half of 2025.

Contractors involved

Quality assurance company Intertek, which is based in the UK, received a contract from Xlinks to provide quality assurance and technical advice for the project in March 2022.

The contractual scope includes the review of marine cable routing, along with survey specification, procurement and tenders. The company will also assist Xlinks in obtaining survey permits.

Intertek conducted a marine permit feasibility study for the interconnector project in May 2021.

XLCC partnered with Salt Ship Design, an independent ship design company, to prepare the design of the cable-laying ship for the project.

MAATS Tech and Global Marine were engaged to support studies related to operational aspects of cable handling.

Global ship management and marine services provider V.Group was selected to support XLCC in the technical development and construction of the cable-laying vessel.

V.Group’s SeaTec division will provide the technical services while its procurement and contracting platform, MARCAS, will assist in the yard selection and appointment.

XLCC contracted HIGHVOLT, a German company, to supply test systems for the pre-qualification and testing of subsea cables in April 2022.

Project benefits

The Morocco-UK power project will contribute to the growth of the domestic solar and wind components manufacturing industry in Morocco. It is expected to generate about 10,000 jobs in Morocco during the construction phase, including 2,000 permanent jobs.

Cable manufacturing facilities to be built in the UK as part of the project are estimated to create 1,350 permanent jobs by 2024.

Furthermore, the interconnector will contribute to the UK’s goal to transition to a zero-carbon electricity system by 2035.

The project is expected to provide low-cost, clean electricity to more than seven million UK homes by the end of 2030.
