Uzbekistan : Distribution Network Digital Transformation and Resiliency Project
Distribution Network Digital Transformation and Resiliency project aims to rehabilitate medium voltage distribution substations and associated overhead lines across the country and modernize the distribution system operations. It will be aligned with the following impact: social and economic development achieved through provision of better infrastructure services. The outcome--distribution grid operation reliability and efficiency improved--will be achieved through the following three outputs: 1) Distribution substations rehabilitated and modernized, 2) Associated distribution lines rehabilitated, and 3) Institutional capacity for financial sustainability and climate resiliency enhanced.

|Project Rationale and Linkage to Country/Regional Strategy||
The electricity demand is expected to double by 2030 from its annual power consumption of 67 terawatt-hours in 2019. To meet the rapidly growing power demand, the government targets to install additional 17 gigawatts (GW) capacity to the existing available capacity of 12.9 GW. This significant addition to the generation capacity should be paced with the enhancement of the transmission and distribution network to ensure the generated electricity, especially from renewable energy resources, is delivered to the end users without interruption. It would take about $10 billion in investments to expand, enhance, and modernize the distribution network by 2030. However, the adequate investment in modernizing the distribution network has been slow because of limited access to the capital market and long-term financing.
Uzbekistan's distribution system comprises more than 260,000 kilometers of 0.4-kilovolt (kV) to 110 kV networks, 1,655 substations, and more than 86,000 transformer points, providing electricity to 7.6 million residential and industrial consumers. More than 50% of distribution lines have been in operation for over 30 years, and 30% of substation transformers require urgent replacement. The aging distribution system has developed serious problems, such as overloads, voltage drops related to increased load demand, and increasingly frequent blackouts. Besides, technical losses in the distribution system remain high, estimated at 13% of the total power generation, resulting in inefficiency and offsetting the government's continued efforts to reduce energy intensity and greenhouse gas emissions.
Uzbekistan's household electrification rate is nearly 100%, but an aging and overloaded electricity system has caused a sustained supply reliability issue, especially in rural areas.
Uzbekistan's aging and dilapidated infrastructure in the power supply chain increasingly results in system inefficiencies, unreliable electricity supply, and uneven access to electricity across provinces, constraining economic development, dampening business confidence, and contributing to widening disparities. Power outages continue to occur, even in urban areas, and are particularly severe in rural areas during the winter seasons. With rising summer temperatures, Uzbekistan has begun to experience electricity supply disruption in the hottest months, in addition to the traditional blackout season of winter. Building up resiliency in the transmission and distribution is crucial to adapt to climate change in parallel with improving supply reliability.
