Given Uzbekistan’s accelerated economic growth despite the ongoing global challenges, the government aims to maintain the momentum by implementing structural reforms that will stimulate demand and expand the private sector. This includes enhancing the resilience of the power sector with the support of the Asian Development Bank. As part of the ‘Distribution Network Digital Transformation and Resiliency Project’, ADB will assist the government to rehabilitate medium voltage distribution substations and associated overhead lines as well as modernize the distribution system operations. To ensure that the developments are climate resilient, FutureWater will be analyzing the impact of climate model projections in the region and develop a detailed climate risk and adaptation assessment.
With a target to increase the gross domestic product from $70 billion in 2021 to $160 billion by 2030, the Government of Uzbekistan is taking steps to ensure that it will be able to meet the spike in electricity demand which is expected to double by 2030. Initiatives include installing an additional 17 gigawatts capacity to the existing available capacity of 12.9 GW, out of which 8 GW will be from renewable energy projects. Currently, the distribution system in Uzbekistan comprises of more than 260,000 kilometers of 0.4-110 kV networks, 1,655 substations and more than 86,000 transformer points. However, more than 50% of the lines have been operational for 30 years and 30% of the substation transformers are in dire need of rehabilitation. Therefore, the Asian Development Bank is working closely with the Joint Stock Company Regional Electric Power Networks (JSC REPN) to: i) Rehabilitate and modernize the distribution substations, ii) Rehabilitate associated distribution lines, and iii) Enhance the institutional capacity for financial sustainability and climate resiliency.
These rehabilitation efforts will also take into account and address the growing impacts of climate change in the region. For this, FutureWater has been assigned to carry out a climate risk and adaptation assessment (CRA). FutureWater will make use of state-of-the-art downscaled Coupled Model Intercomparison Project Phase 6 (CMIP6) ensembles, and other relevant hazards and local information to develop this CRA. Insights from the CRA will be used to devise adaptation strategies. Additionally, FutureWater will be reviewing the existing meteorological monitoring network and recommending additional potential monitoring sites for improved surveillance in the country. To further assist the Government of Uzbekistan actualize its second Nationally Determined Contribution (NDC) agenda which seeks to reduce greenhouse gas (GHG) emissions per unit of GDP by 35% (compared to the level in 2010), by the year 2030, FutureWater will also develop a GHG account and prepare a Paris Agreement alignment assessment.
