Angola has installed its first submarine electricity cable in the municipality of Mussulo, marking a major milestone in the country’s energy infrastructure. The cable is expected to significantly enhance the region’s power supply, increasing capacity from 20 to 30 megawatts.
According to a statement from the Mussulo municipal administration, the cable was installed on Wednesday, July 2, 2025. In addition to carrying electricity, the cable also includes integrated optical fiber, making it a dual-purpose infrastructure asset.
The submarine cable stretches 1,800 meters and weighs over 70 tons. It will serve as a critical reinforcement to Mussulo’s energy supply, improving reliability and supporting the area’s growing demand for electricity.
“This project marks a significant step in strengthening the basic infrastructure needed to support public and private investments, as well as new housing developments,” said Mussulo’s municipal administrator, Baudilio dos Santos Baptista Vaz.
Elísio Augusto, an engineer from Mark Cables—the company involved in the Mussulo Peninsula Electrification Project—explained that the new line provides a second, alternative power source.
“The entire process will be completed within a week and will also benefit mobile phone operators by improving connectivity,” he added.
The municipal statement also outlined the final stages of the installation: at the end of the 1,800-meter stretch, a floating platform will be positioned to support the cable.
A second cable from Kapossoca, of similar length, will be anchored toward this platform, where the two will be connected to complete the system.
This project not only strengthens energy security in Mussulo but also lays the foundation for further technological and economic development in the region.
