Project features

ACWA Power signed an investment agreement with the MoE to design, finance, build and operate two wind farms - Bash WPP and Dzhankeldy WPP - in the Bukhara region, Uzbekistan with a total installed capacity of ca.1 GW. The proposed project sites of Bash & Dzhankeldy WPP are located approximately 30 km west of Kokcha and approximately 7 km west of Ayakguzhumdy, respectively. The Client hired Juru to conduct Power Evacuation & Grid Compliance Studies along with Electrical Interconnection Facility (EIF) Design and provide support in obtaining necessary permissions from national TSO to connect wind farms to the grid (Technical Conditions).
