A Digital Substation Strengthens Namibia’s Coastal Power Network
SOURCE SIGNAL
NamPower commissioned and energised the new Sekelduin Substation near Swakopmund on 24 September 2025, adding approximately N$394 million of new electricity infrastructure to Namibia’s coastal transmission network.
The 132/66/33 kV facility represents a significant technological milestone for the national grid. NamPower describes Sekelduin as Africa’s first fully digital substation, introducing advanced digital technology intended to improve the monitoring, control and operation of the transmission system.
The new substation becomes the principal transmission supply point for existing infrastructure serving Swakopmund, the NamWater South bulk-water scheme supplying Husab Uranium Mine, and ErongoRED’s 33 kV network.
The investment therefore adds electricity capacity and resilience in a region experiencing substantial mining, industrial, utility and urban demand.
COUNTRY IMPACT
Reliable electricity infrastructure is fundamental to Namibia’s ability to accommodate new mining, industrial and urban investment.
The Erongo Region contains some of the country’s most important mining and industrial activity, while the coastal economy continues to expand around Walvis Bay, Swakopmund and surrounding developments.
Sekelduin strengthens the electricity network supporting this activity, including infrastructure associated with water supply to Husab Uranium Mine and electricity distribution through ErongoRED.
Its significance therefore extends beyond the substation itself.
The project demonstrates that Namibia is investing in the supporting utility infrastructure required for economic expansion, while introducing advanced digital technology into the national transmission system.
As mining, logistics, processing and urban development increase electricity requirements, investment in grid capacity provides an important indication that the underlying infrastructure is being strengthened alongside that growth.
RELEVANCE TO SUNGATE
Sungate is a long-term mixed-use development whose potential is linked to the broader expansion of Namibia’s economy and the infrastructure required to support that expansion.
Sekelduin provides evidence of a wider national pattern: as economic nodes grow and new industrial demand emerges, the electricity infrastructure supporting those nodes must expand with them.
That principle is directly relevant to Sungate.
The development is positioned adjacent to Hosea Kutako International Airport at the convergence of air, road and rail, with commercial, logistics, hospitality, industrial and supporting-service uses anticipated within the wider development concept.
Growth in these activities ultimately depends on reliable bulk infrastructure.
Sekelduin therefore matters to Sungate not because the substation supplies the development directly, but because it demonstrates Namibia’s continuing investment in the energy backbone required to support larger economic and industrial nodes as they develop.
