Tanzania - 400 kV Transmission Line Iringa-Shinyanga
The objective of the project was to reinforce the existing 200 kV transmission line from Iringa to Shinyanga by constructing approximately 700 km of 400 kV transmission line and associated facilities.
The Iringa - Shinyanga transmission line is divided into 3 line sections: Iringa - Dodoma (225 km), Dodoma - Singida (227 km), and Singida - Shinyanga (228 km).
The project was carried out for Tanzania Electric Supply Company (TANESCO).

UAE - Establishment of Power Supply to Yas Island
In order to sustain the development of different regions of Abu Dhabi Island, ADDC, in collaboration with private developers, initiated several projects to expand the electrical network by adding primary substations and integrating them into the existing power network. Among other projects, the private developer ALDAR Properties PJSC embarked on the development of Yas Island to develop it into a major touristic, residential and commercial city located in the suburbs of Abu Dhabi Island.
Accordingly, a project was initiated to provide consulting services for the network expansion projects, both for temporary and permanent power supply, with the aim to assure the compliance of the installations with ADDC's / ADWEA's design guidelines, specifications and the overall project schedule.
