Project features

ADB supported the Government of Uzbekistan and JSC NEGU to strengthen the country’s transmission grid by preparing a follow-up investment project aimed at accommodating rapid demand growth and large-scale renewable energy integration. The project includes the construction of approximately 440 km of 220/500 kV transmission lines and expansion of six substations across three major corridors.

Juru was engaged to deliver the complete technical, financial, E&S due diligence of the project, aligned with national legislation (Presidential Decree PD-51) and ADB project preparation standards. The assignment was structured in two phases: preparation of the Project Concept for national approvals, followed by full-scale due diligence and preparation of the Project Appraisal Document.
