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 OPGW and telecommunications, together with about 47 km of 33 kV medium-voltage network, connect the plant and its host facilities to the grid.

SCADA, protection, control and metering systems tie the installation together. They allow the plant to be monitored, protected and operated as a single integrated facility.

One contract, one responsible party

Under the EPC model, ICCO held single-point responsibility for the full project cycle — design, engineering, procurement, supply, construction, installation, testing and commissioning. The work closed with energization, synchronization to the grid, performance verification and final handover to Upper Nile Cement.

Why it matters

South Sudan has a strong solar resource and a pressing need for dependable power. Pairing utility-scale generation with dedicated transmission and substations gives an industrial client a firmer supply and supports wider grid access along the Kapoeta–Nimule corridor.

Delivered by ICCO

All design, engineering, procurement, construction, testing and commissioning for this project was executed by ICCO — the EPC contractor awarded the contract and solely responsible for delivery through to energization and handover.

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 ...

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...
