Distribution Network Development Master Plan project. Funded by ADB

Name of Client: ADB/Joint Stock Company Regional Electric Networks (REN)
Status: Completed (Completion Date (Month/Year): 21/09/2022)
Narrative description of Project:
For the preparation of distribution network development masterplan and smart-grid road map, analytical works and preparation of the distribution network development master plan (110 kV and below) will be performed. This will help to address high losses, reliability issues, and meet the increasing electricity demand in the distribution sector.
The master plan will (a) review the national investment program and transmission grid expansion plan currently under development with World Bank’s assistance in consideration of the long-term power supply–demand balance via solid middle-term provision of electricity demand; (b) identify current and future major load centers and problems of balancing electricity supply and demand, potentially including electric vehicle integration, distributed renewable energy generation, and energy storage; (c) conduct least-cost analysis among technology options and derive optimal configuration of low voltage networks using modern technology; (d) set an automation goal in time and develop associated smart-grid road map; and (e) identify short, medium, and long-term investment priorities and cost estimates. The master plan will recommend technology options to digitalize the distribution network (automated control system in the power supply chain from substations – distribution point – transformer point – consumer), accommodate prospective distributed small-scale renewables and energy storage systems, and identify ways to maximize the use of the advanced metering infrastructure with a view to transforming the grid into a cleaner, smarter, and more flexible one while lowering the total system cost.

Description of actual services provided in the assignment:

•   Study of data on single-line schemes of primary/secondary distribution networks of the Republic of Uzbekistan;
•   Data collection on the components of the distribution system (types of lines and transformers), as well as on the physical attributes of the distribution system components;
•   Collecting data and development of power system models for 2021, 2025, and 2030 based on the load flow analysis software format. Analyzing distribution network. Selecting technologies, design, and equipment in consideration of the long-term climate change impact and secure climate resilience. (iv) Economic evaluation of potential projects and prioritization of including benefits and costs: (a) benefit due to loss reduction, (b) benefit due to reduction of unserved demand costs, (c) benefit due to improved reliability, (d) investment costs, and (e) operation and maintenance costs. (v) Preparation of a 5-year distribution network development plan for JSC REN with a vision for 10-year development roadmap.
