Saudi Arabia's ACWA Power intends to build a 1.5 GW wind farm in Karakalpakstan in north-west Uzbekistan.
"This project will be the largest wind farm not only in the region, but the whole world. The wind farm will be able to provide electricity to 1.65 million households and prevent 2.4 million tonnes of carbon emissions per year," the Uzbek ministry said.
