Notice:

SEKELDUIN SUBSTATION – A DIGITAL MILESTONE (A FIRST FOR AFRICA – DESIGNED AND BUILT BY AFRICANS)   NamPower successfully commissioned and energised its new indoor 132/66/33 kV Sekelduin Substation, located east of Swakopmund, on 24 September 2025. Sekelduin Substation is distinguished as the first fully digital substation on the African continent, with a total project investment of N$ 394 million.   This newly commissioned infrastructure added to the NamPower transmission network unlocks coastal load growth, strengthens reliability, and future-proofs the Erongo region grid with a digital substation employing process bus application in accordance with IEC 61850 standards. The substation uses Mixed Technology Switchgear (MTS), compact hybrid AIS/GIS, plus Metal Enclosed GIS at 33 kV, with ACTOM as the principal equipment supplier and integrator.   The digital substation design employs process and station bus, which reduces copper cable runs, improves remote asset monitoring, enhances fault location accuracy, and strengthens cyber-secure SCADA integration, addressing both performance and copper-theft risks. The digital application also provides a platform for future AI/ML integration, positioning NamPower among the top utilities in the world.   Core to the secondary system design is the hybrid architecture that integrates digital and conventional hard-wired protection systems based on IEC 61850. The IEC 61850-9-2LE based main protection system comprises a redundant process and station bus via merging units/ process interface units, utilising sampled values and GOOSE communication. The backup protection system features a station bus and GOOSE, with hardwired connections to conventional CTs and VTs.   The now commissioned and energised Sekelduin Substation will function as a 132/66/33kV indoor switching station making use of compact mixed technology gas-insulated switchgear (MTS) for the 132kV and 66kV circuits, while the 33kV circuit makes use of gas-insulated fixed-pattern metal-enclosed switchgear. The substation will feature two voltage transformation levels derived from the 132kV busbar: 66kV and 33kV. The high-voltage (HV) equipment is housed indoors in a custom-designed building, in conjunction with SCE Consulting Engineers and TDx Power and constructed by Nexus Building Contractors. This is to protect the equipment from the highly corrosive environments of the marine and desert regions.   Sekelduin Substation marks a decisive step-change in Namibia’s transmission architecture and a continental first - conceived, engineered, and delivered by Africans. Sekelduin Substation proves Africa can design and deliver world-class digital grid infrastructure—melding MTS/GIS with IEC 61850 process and station bus to harden N-1 resilience. Built by Africans for Africa, it’s a scalable blueprint for AI/ML-ready, cyber-secure substations that future-proof Namibia’s growth and set a new operational benchmark for Namibia.

NamPower breaks ground on largest Solar PV Power Station to date   19 June 2025 – Driven by its commitment to the sustainable development of the country, NamPower held a media groundbreaking ceremony to officially mark the commencement of the construction of the 100 MW Sores |Gaib Power Station - situated 33 km northwest Rosh Pinah. Sores |Gaib, which in Khoekhoegowab means “Power of the Sun”, will be NamPower’s largest Solar PV Power Station to date. Upon completion, the power station will contribute significantly to the national energy mix, displacing a significant amount of imported energy and reducing reliance on fossil fuels. Additionally, Sores |Gaib will play a pivotal role in fostering economic development, enhancing energy independence, and strengthening climate resilience in Namibia. NamPower’ s total investment in this project stands at N$1.6 billion. The project is funded through a combination of a loan from KfW (German development bank, equivalent to about N$1,3 billion) and the remainder from NamPower’ s own reserves. This loan was facilitated within the framework of the intergovernmental agreement, underscoring the enduring partnership and cordial relations between the Government of Namibia and the Government of the Federal Republic of Germany. During the construction phase of this project, over 300 direct jobs are expected to be created with the aim of employing local labor and thereby promoting skills development. In addition, the Engineering, Procurement and Construction (EPC) Contractor has made a commitment to allocate 25% of the Contract Price, equivalent to N$356 million, towards Local Content. NamPower has prioritized local content participation and skills development as integral components of its implementation strategy. Also, through the project’s Environmental and Social Management Plan, the company has made firm commitments to preserve the integrity of the environment through protecting biodiversity and promoting responsible labor and community engagement practices. NamPower’s mandate has always been clear: to generate, transmit, and where required distribute electricity in a manner that is reliable, affordable, and sustainable. In recent years, however, this mandate has gained greater significance as the world responds to the challenge of climate change and the urgency of energy transition. NamPower Managing Director Kahenge Haulofu emphasized that the 100 MW Sores |Gaib Power Station Project represents progress and a long-term commitment to the sustainable development of our country. “Our country has abundant sun and we as a nation are ready to seize the opportunities that renewable energy offers. The 100 MW Sores IGaib Power Station is a critical step in fulfilling that potential”, he stated in his speech at the groundbreaking event. The commercial operation date of the power station is set for June 2026.
