From first energization to final handover: commissioning the Kapoeta-Nimule solar and grid project

Image
Project: Kapoeta–Nimule 72 MWp Solar PV & Grid Infrastructure | Republic of South Sudan | Full EPC delivered by ICCO | Completed 29 July 2025 Energization begins at the 220/132 kV substation. A power plant is not finished when the last panel is installed. It is finished when it has been proven to work safely with the grid. On the Kapoeta–Nimule project, completed by International Consolidated Contractors Offshore SAL (ICCO) on 29 July 2025, that proof covered a 72 MWp solar plant, two substations rated 2 × 100 MVA and 2 × 50 MVA, and about 65 km of transmission and medium-voltage network. This article explains what that final phase involves. Why commissioning carries so much weight A plant connected at 220 kV becomes part of the national transmission system. A fault inside the plant can affect other users, and a disturbance on the grid can damage the plant. Commissioning demonstrates that every protection, control and communication syste...

Eighteen months, one contract: delivering 72 MWp, two substations and 65 km of lines in South Sudan

Project: Kapoeta–Nimule 72 MWp Solar PV & Grid Infrastructure | Republic of South Sudan | Full EPC delivered by ICCO | USD 98,783,098 | 18 months | Completed 29 July 2025 Completed Kapoeta-Nimule solar plant and grid connection. On 29 July 2025, International Consolidated Contractors Offshore SAL (ICCO) completed the 72 MWp Kapoeta–Nimule solar project and its grid infrastructure for Upper Nile Cement. The contract began on 1 February 2024, ran 18 months and was valued at USD 98,783,098. The headline figure is the solar capacity. The harder task was delivering several interdependent packages of work on one schedule, across two countries’ logistics and in the conditions of South Sudan. Many packages, one programme The scope combined work that is often split between several contractors: A 72 MWp grid-connected solar PV plant, including civil and electrical works A 220/132 kV substation rated 2 × 100 MVA A 132/33 kV substation rated 2 ...

Powering cement production with the sun: what the Kapoeta-Nimule project shows

Project: Kapoeta–Nimule 72 MWp Solar PV & Grid Infrastructure | Client: Upper Nile Cement | Republic of South Sudan | Full EPC delivered by ICCO | USD 98,783,098 | Completed 29 July 2025 A 72 MWp grid-connected solar plant delivers clean power to Upper Nile Cement. Cement is one of the most energy-intensive industries in the world, and reliable power decides whether a plant can run at all. In July 2025, Upper Nile Cement took delivery of a 72 MWp grid-connected solar plant and its grid infrastructure, built by International Consolidated Contractors Offshore SAL (ICCO) . The project is a useful case study of how heavy industry can secure its own clean power at scale in a frontier market. The energy problem industry faces Industrial plants need large amounts of electricity, delivered steadily. Interruptions stop production, damage equipment and waste material already in process. In South Sudan, grid capacity has long trailed demand, and many industrial users...

Inside the Kapoeta-Nimule project: from 72 MWp of solar to a 220 kV grid connection

Project: Kapoeta–Nimule 72 MWp Solar PV & Grid Infrastructure | Upper Nile Cement | Republic of South Sudan | Full EPC delivered by ICCO | Completed 29 July 2025 The 72 MWp grid-connected solar PV plant. The Kapoeta–Nimule project is a complete power system, not only a solar farm. It generates electricity, raises it through three voltage levels and delivers it to the high-voltage grid. International Consolidated Contractors Offshore SAL (ICCO) delivered every part of that chain under a single EPC contract, completed on 29 July 2025. Component Size Role Solar PV plant 72 MWp Grid-connected utility-scale generation 220/132 kV substation 2 × 100 MVA Line bays, protection, control, metering, SCADA 132/33 kV substation 2 × 50 MVA HV/MV switchgear, protection and control 132 kV transmission line ~18 km double-circuit Power evacuation, with OPGW and telecoms 33 kV MV network ~47 km Distribution and interconnection fa...

International Consolidated Contractors Offshore SAL (ICCO) has completed the 72 MWp Kapoeta–Nimule Power Project and associated grid infrastructure for Upper Nile Cement in the Republic of South Sudan. The project was completed on 29 July 2025 under an 18-month engineering, procurement and construction (EPC) contract valued at USD 98,783,098. The scope covered a grid-connected, utility-scale solar photovoltaic plant and the power-evacuation and grid-interconnection infrastructure needed to deliver its output reliably. ICCO built a 220/132 kV substation rated 2 × 100 MVA and a 132/33 kV substation rated 2 × 50 MVA. About 18 km of double-circuit 132 kV overhead transmission line, including ...
