CEEG has reached a key milestone on its Tanzania port power upgrade project, with all equipment successfully delivered and ready for commissioning as part of the port's shore power infrastructure.
A Demanding Operating Environment
Shore power applications at busy port facilities are inherently challenging — high inrush currents, complex harmonic loads, and long continuous operating hours are all part of the territory. Add the coastal climate of East Africa, with its persistent heat, humidity, and salt-laden air, and the bar for equipment reliability is set considerably higher than for a standard onshore installation.
A Double-Deck Substation Built Around the Client's Constraints
To meet the project's specific requirements, CEEG engineered a custom double-deck compact substation. Unlike a conventional single-story layout, the double-deck arrangement stacks the high-voltage compartment, transformer bay, and low-voltage section vertically — delivering full electrical functionality within a significantly reduced footprint. In a working port where ground space is at a premium, this kind of spatial efficiency matters.
Purpose-Built for the Conditions
Beyond the structural design, several targeted enhancements were incorporated to address both the shore power environment and the coastal East African climate:
Heavy-Duty Corrosion Protection — The substation enclosure and transformer housing are finished to the highest available anti-corrosion specification, ensuring long-term resistance to rust and material degradation in a marine atmosphere.
Harmonic and Surge Tolerance — Shore power loads are far from clean. The equipment is designed to handle the harmonic distortion and voltage fluctuations inherent to port electrical systems without compromising supply quality.
Factory Pre-Assembly for Fast Deployment — The compact substation was fully assembled and tested at the factory before shipment, meaning on-site work is limited to foundation installation and cable termination. This approach shortens the construction schedule and minimizes disruption to ongoing port operations.
Another Reference Project in Africa
The Tanzania port project adds to a growing portfolio of infrastructure work CEEG has completed across Africa, building on an established track record in Asia, Europe, Latin America, and beyond — spanning power grids, renewable energy, rail transit, and industrial applications.
The project also demonstrates the depth of CEEG's capability in port power systems. From the 35kV main transformer through to 11kV distribution transformers and end-point compact substations, the full power supply chain was covered under a single, coordinated solution.
CEEG will continue to bring its focus on safety, energy efficiency, and environmental responsibility to power and new energy system projects around the world — supporting infrastructure development across Belt and Road countries and beyond.
