The Adani Group is in talks with the Uzbekistan government to develop four pumped storage projects (PSPs) with a combined capacity of around 5 GW as the Central Asian country looks to expand renewable energy capacity and strengthen grid stability.
Representatives of the group held discussions with Uzbekistan government officials in August, including Investment, Industry and Trade Minister Laziz Kudratov, over the proposed projects.
The initial discussions cover four projects of roughly 5 GW across different locations, with one project expected to be developed in each region.
Pumped storage projects use surplus electricity to pump water to an upper reservoir when demand is low and release it through turbines when electricity demand rises, allowing the system to provide long-duration energy storage and support grid stability.
Uzbekistan is seeking to rapidly expand renewable power capacity and diversify its electricity mix. The country has committed to sourcing 50 per cent of its electricity from renewables by 2030 and achieving net-zero emissions by 2050.
The proposed Adani investment would add to the group's growing pumped storage portfolio. Adani Green Energy is currently developing around 3 GW of PSP capacity in India across projects in Andhra Pradesh and Maharashtra, with additional projects under development.
Uzbekistan, meanwhile, has identified pumped storage as part of its strategy to integrate increasing amounts of renewable generation into its electricity system.
