Spain-Morocco 29-Kilometer Subsea Cable Powers Moroccan Energy 2026

The 29-kilometer subsea cable between Spain and Morocco is often called the "umbilical cord" of Moroccan energy, a critical link that keeps the North African country's power grid stable and connected to Europe. This cable, known as REMO, is more than just infrastructure—it's a symbol of the complex relationship between the two nations and a strategic asset that could be leveraged in times of political tension.

Recent events, such as the migration crisis in Ceuta in July, have brought renewed attention to this underwater link. While misinformation spread on social media, the cable's importance remains undisputed. Here's what you need to know about this vital connection and why it matters.

What Is the REMO Subsea Cable?

The REMO cable is a high-voltage direct current (HVDC) submarine power cable that connects Spain and Morocco across the Strait of Gibraltar. It was first conceived in the 1980s during a period of growing cooperation between Europe and the Maghreb. The goal was twofold: to stabilize the Moroccan grid and to create a channel for electricity exchange that would optimize generation in both systems.

Stretching 29 kilometers, the cable runs under the sea from the Spanish coast to Morocco. It is part of a broader interconnection that allows electricity to flow between the two countries, providing Morocco with access to European energy markets and giving Spain a reliable partner for energy exchange.

Why Is It Called the "Umbilical Cord"?

The term "umbilical cord" reflects the cable's role in supplying Morocco with essential energy. Without it, Morocco's power grid could face significant instability, especially during peak demand or when domestic generation falls short. The cable ensures a steady flow of electricity, supporting both everyday needs and industrial growth.

The Strategic Importance for Morocco

Morocco has been investing heavily in renewable energy, aiming to become a leader in solar and wind power. However, its grid still requires support from external sources, particularly when renewable output fluctuates. The REMO cable provides a crucial backup, allowing Morocco to import electricity from Spain when needed.

Moreover, the cable enables Morocco to export surplus energy to Europe, creating a revenue stream and strengthening economic ties. This two-way exchange is beneficial for both countries, but for Morocco, it's a lifeline that ensures energy security.

• Grid stability: The cable helps balance supply and demand, preventing blackouts.
• Renewable integration: It supports Morocco's ambitious renewable energy targets by providing a buffer.
• Economic benefits: Energy exports generate income and foster regional cooperation.
• Strategic leverage: The cable gives Spain a degree of influence over Morocco's energy sector.

Spain's Perspective: A Double-Edged Sword

For Spain, the cable represents both an opportunity and a risk. On one hand, it strengthens diplomatic ties and provides a market for Spanish electricity. On the other, it gives Spain a powerful tool that could be used in political disputes—a fact not lost on either side.

During the Ceuta crisis, some speculated that Spain could "switch off" Morocco's power by cutting the cable. While such a move would be extreme and unlikely, the mere possibility underscores the cable's geopolitical significance. It's a reminder that energy infrastructure is never just about energy; it's about power in every sense.

Technical Specifications

The REMO cable is a marvel of engineering. It operates at high voltage to minimize losses over the 29-kilometer stretch. Here are some key specs:

What Happened During the Ceuta Crisis?

In late July, tens of thousands of migrants crossed into Ceuta, a Spanish enclave in North Africa, from Morocco. The sudden influx strained relations between the two countries and sparked a wave of misinformation online. Amid the chaos, the REMO cable emerged as a talking point, with some suggesting it could be used as leverage.While no action was taken regarding the cable, the episode highlighted how energy infrastructure can become entangled in diplomatic rows. It also showed the importance of reliable information in times of crisis. The background to this story is set out in Why Ceuta Migration Crisis Happened: Spain-Morocco Border.

What to Watch Next

The REMO cable will continue to play a central role in Spain-Morocco relations. As Morocco expands its renewable capacity, the cable's importance may grow, enabling greater energy exchange. At the same time, any political tension could put the cable in the spotlight again. A closer look at the same subject appears in Ceuta to End Diesel Isolation with Submarine Power Cable Link.
