In Uzbekistan, the role of battery energy storage systems (BESS) is rapidly growing. According to the Ministry of Energy, their total capacity has reached 1545 MW, allowing them to cover more than 13.5% of evening peak electricity consumption. Thus, approximately one in eight kilowatts during peak load hours is provided by previously stored energy.
The development of BESS has become part of the country's large-scale energy transformation, aimed at expanding the share of renewable energy sources and increasing the stability of the energy system. Today, 15 solar power plants with a total capacity of 3930 MW and 5 wind power plants with a total capacity of 1652 MW operate in the republic. Since the beginning of the year alone, they have generated more than 4 billion kWh of environmentally friendly electricity.
The first major storage system projects were launched in 2024 in Fergana and Andijan regions, where 150 MW installations were commissioned in each. In 2025, new capacities were added, bringing the total capacity to 1545 MW and energy capacity to 2600 MWh. The Ministry of Energy notes that the development of BESS reduces the load on thermal power plants, cuts natural gas consumption, and increases the reliability of energy supply. By 2026, it is planned to increase the system capacity to 2000 MW, and by 2030, to 4.5 GW.
