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