Project features

The Beruniy 200 MW Wind Power Project is a large-scale renewable energy development located in the Qorao‘zak District, Karakalpakstan Republic, on a mountain ridge east of the village of Karatau, approximately 70 km southeast of Nukus City. The project aims to design, construct, and operate a 200 MW wind farm and a 100 MW / 100 MWh Battery Energy Storage System (BESS).

The development includes the construction of 26 wind turbine generator (WTG) units, associated 35 kV collector transmission lines, and 35/220 kV step-up substations for grid interconnection. The project also involves the expansion of the Karatau switching station and the Beruniy substation to enable efficient power evacuation to the national transmission grid.

The EPC Contractor, Sinohydro Tashkent, has been assigned full responsibility for the engineering, procurement, construction, and commissioning of the project facilities.

The engineering services are carried out by Juru Energy Consulting under a dedicated agreement covering the full scope of design, adaptation, and supervision works, in coordination with the EPC Contractor and the Owner’s Engineer.

Key project components include:

• Expansion of Karatau Switch Station (5 new bays)
• Expansion of Beruniy Substation (2 new bays)
• Design of 220 kV overhead transmission line (OHL) — approx. 60 km total length (including D/S, D/C, and single-circuit sections)
• Telecommunication and SCADA systems for the Wind Farm and BESS substations
• ECA Design for the whole Project
• Site supervision and technical assistance during construction
• Adaptation of all design documentation to comply with Uzbekistan codes and standards 

Services provided

The assignment covered the complete engineering design, adaptation, and coordination of all systems related to the 200 MW Beruniy Wind Farm Project, including substations, overhead transmission lines, BESS integration, and communication systems.

1. Substation Expansion (Karatau & Beruniy)

• Basic and detailed design for five-bay 220 kV extension at Karatau Switch Station and two-bay extension at Beruniy Substation.
• Development of single-line diagrams, general layouts, and control & protection schemes in compliance with IEC, IEEE, and Uzbek standards.
• Preparation of technical specifications, calculation reports, and Bill of Quantities (BoQ) for procurement and construction.
• Design of earthing, lightning protection, auxiliary AC/DC supply, and control & telecom systems.
• Coordination with local authorities (NEGU, UzEnergoInspection, Ministry of Construction) for review and approval.

2. 220 kV Overhead Transmission Line

• Route survey and profile measurement of the 220 kV OHL corridor (~60 km).
• Development of tower profiles, topographic maps, and crossing details (existing OHLs, telecom lines, railways, etc.).
• Detailed design of tower foundations, conductor arrangement, and mechanical calculations.
• Site visits to verify tower locations and document field conditions with photo evidence.

3. Telecommunication and SCADA System

• Design of telecommunication networks connecting the Wind Farm, BESS, and substations.
• Integration of SCADA, metering, and remote monitoring systems.
• Preparation of interface documentation and coordination with local telecom operators and system operators.

4. Emergency Control Automatics (ECA)

• ECA system design will be developed in two stages in normal local engineering practice. At the first stage, stability analysis will be done to cover a provision of information on the ECA devices envisaged by the Project that shall ensure the stable operation of the plant with the power system of Uzbekistan. Emergency Control Automatics (ECA) systems and devices under the scope of this Project must comply with the interstate standard GOST 34045-2017 “Electric power systems. Operational dispatch control, emergency control automatics of power systems modes. Emergency control automatics of power systems. Norms and Requirements" and "Provisions on emergency control automation of the Unified Central Asian Power Systems" approved by the decision of Central Asian Co-ordination Committee. The layout of the ECA devices required for the interconnection of the plant including ECA’s number and location will be prepared

5. Site Supervision and Technical Support

• Technical assistance during construction and installation works.
• Review of manufacturer drawings and shop documents.
• Compilation of as-built drawings reflecting construction changes.

All works were carried out in accordance with the Uzbekistan Building Code, Eurocodes, IEC, ASCE, and IEEE standards, ensuring full compliance with national and international regulations.
