KHOBI II Hydro Power Project: A Strategic Energy Landmark for Georgia

Located in Georgia's Samegrelo-Zemo Svaneti region, the KHOBI II Hydro Power Project stands as a cornerstone of the country's independent energy development strategy and the largest hydropower station independently built by Georgia since the Soviet era. With a total installed capacity of 46 MW, the run-of-river hydropower plant is built on the Khobi Tsali River and features a sophisticated fluid transportation and control system including a 6.9 km non-pressure tunnel and an 800 m pressure penstock, designed to harness clean hydropower resources for sustainable energy supply.

Officially commissioned in October 2024 after a grand opening ceremony led by Georgian Prime Minister Irakli Kobakhidze, the project delivers a pivotal boost to Georgia's energy independence, with an annual power generation capacity sufficient to meet the electricity needs of 50,000 local households. As a critical civil engineering and energy infrastructure project, KHOBI II imposed extremely stringent technical requirements on fluid control equipment, driven by the unique operational characteristics of hydropower stations:

- High-pressure and large-flow working conditions: The water intake and pressure pipeline systems require large-diameter valves with excellent pressure-bearing capacity and low flow resistance to ensure efficient water flow transmission and stable power generation.

- Zero-leakage sealing performance: Reliable sealing is essential to prevent water loss, avoid cavitation damage to turbine units, and ensure the safety of maintenance operations for hydropower equipment.

- Abrasion and corrosion resistance: Valves and fittings must withstand long-term contact with water media and potential sediment erosion, requiring high-quality materials and structural design to ensure long service life.

- Quick and reliable operation: Core valves need to realize fast on-off control to respond to emergency working conditions such as unit overspeed, providing a safety guarantee for the entire power generation system.

- Perfect compatibility with system integration: Fluid control equipment must be seamlessly matched with the hydropower station's turbine units, pipelines and automation systems to ensure the coordinated and efficient operation of the whole plant.

Against this backdrop, the KHOBI II project authority adopted strict global selection criteria for valve suppliers, focusing on R&D and manufacturing capabilities for large-diameter hydropower valves, project experience in energy infrastructure, product performance reliability and one-stop technical support capabilities. After in-depth technical communication and drawing verification, WEIZIDOM stood out from international competitors with its professional hydropower valve solutions and mature large-diameter valve manufacturing technology, becoming the core fluid control equipment supplier for the KHOBI II Hydro Power Project.

WEIZIDOM's Tailored Hydropower Valve Solution: Customized for KHOBI II's Operational Needs

In 2020, WEIZIDOM received the valve procurement request for the KHOBI II Hydro Power Project and immediately set up a professional technical team to conduct in-depth research and analysis of the project's construction drawings and fluid control requirements. Combining its decades of experience in the hydropower valve industry and technical expertise in large-diameter valve design, WEIZIDOM provided a one-stop fluid control solution fully adapted to the project's characteristics, and in 2022 successfully completed the production and supply of all core products, with a total contract value of USD294,664.9. All products are independently R&D and manufactured by WEIZIDOM, adhering to international hydropower equipment standards, and have undergone strict performance testing and quality inspection to fully meet the high-standard operational requirements of the KHOBI II hydropower station.

Core Product Portfolio: High-Performance Valves for Hydropower Fluid Control

WEIZIDOM's supply for the KHOBI II project covers the key fluid control links of the hydropower station, including water intake, pressure pipeline, and water release systems, with core products featuring high reliability, high adaptability and high integration:

- DN2400 Double Eccentric Butterfly Valve: As the core control valve for the project's large-diameter water pipeline, this product is engineered with a professional double eccentric structural design for hydropower working conditions, boasting multiple technical advantages that perfectly fit the project's needs. The double eccentric design (axial offset of the valve stem + radial offset of the sealing surface) realizes friction-free opening and closing of the valve plate, which greatly reduces the wear of the sealing surface and ensures long-term zero-leakage performance—a critical requirement for hydropower station water intake systems. With a large-diameter DN2400 caliber, it provides excellent large-flow transmission capacity with low flow resistance, effectively reducing energy loss in the water pipeline system. The valve body is made of high-quality cast steel with anti-corrosion and anti-abrasion treatment, able to withstand the high-pressure impact and sediment erosion in hydropower station pipelines, and its optimized hydrodynamic design significantly reduces the risk of cavitation damage even at high flow velocities, ensuring stable operation under harsh working conditions. In addition, the valve is designed with a modular structure, which can be perfectly matched with electric and hydraulic actuators, realizing quick on-off control and seamless connection with the hydropower station's automation system, providing a reliable safety guarantee for the turbine units.

- Ball Valves: Supplied for the precise control of the hydropower station's branch pipelines and auxiliary systems, WEIZIDOM's ball valves feature a full-bore design with excellent sealing performance and quick on-off characteristics, suitable for the accurate regulation of medium flow in high-pressure small-diameter pipelines, and can effectively prevent medium backflow to protect the safety of auxiliary equipment.

- Air Valves: As an essential accessory for the hydropower station's pipeline system, the air valves are used to exhaust air from the pipeline during water filling and inhale air during drainage, effectively preventing the formation of air pockets and vacuum in the pipeline, avoiding water hammer damage and ensuring the safe and stable operation of the entire pipeline system.

- Precision Cast Steel Fittings: Custom-manufactured to match the large-diameter valves and pipelines of the KHOBI II project, the cast steel fittings include elbows, tees and reducers with high structural strength and dimensional accuracy. Made of the same high-quality cast steel as the core valves, they feature excellent pressure-bearing capacity and corrosion resistance, realizing seamless connection with the valve products and ensuring the smooth flow of the medium in the pipeline system with minimal pressure loss.

Strict Quality Control: Ensuring Reliable Performance for Hydropower Operations

All products supplied by WEIZIDOM for the KHOBI II project have undergone a rigorous multi-stage quality control process, from raw material procurement to production manufacturing, assembly testing and pre-delivery inspection. The raw materials for cast steel valve bodies and fittings are selected from high-quality alloy steel that meets international hydropower equipment standards, with strict chemical composition and mechanical property testing to ensure material reliability. In the production process, advanced CNC machining equipment and precision casting technology are adopted to ensure the dimensional accuracy and structural stability of large-diameter valves and fittings.

Before delivery, all products have passed comprehensive performance tests including 1.5 times nominal pressure shell strength test, 1.1 times nominal pressure sealing test, operation torque test and high-low temperature adaptability test, fully verifying the pressure-bearing capacity, zero-leakage performance and operational flexibility of the valves. For the core DN2400 double eccentric butterfly valve, WEIZIDOM also conducted a special cavitation resistance test and hydrodynamic performance test to ensure its stable operation under the large-flow and high-velocity working conditions of the hydropower station. The strict quality control system ensures that every product delivered to the KHOBI II project meets the highest technical standards, laying a solid foundation for the long-term stable operation of the hydropower station.
