Hydropower Knowledge

Hydropower remains one of the most reliable and flexible sources of renewable energy. At the heart of every hydroelectric plant lies a complex interplay of hydraulic and mechanical systems, yet no function is more fundamental than the management of water flow. Flow control equipment is the nervou...Read more »

Hydroelectric power plants harness the kinetic energy of flowing water to generate clean, renewable electricity. While the turbines and generators often capture the spotlight, the transformers used in these facilities play an equally critical role in ensuring that the generated power reaches the ...Read more »

In micro hydro power systems (typically below 100 kW), the generator produces electricity at a relatively low voltage, often between 120 V and 480 V. To transmit this power efficiently over any distance or to connect to the utility grid, a step‑up transformer is essential. This article discusses ...Read more »

Low-head hydropower stations are those operating with a water head of typically 2 to 30 meters. At such modest heights, the gravitational force available to drive a turbine is limited. Conventional turbine types like Pelton wheels (designed for very high heads) or Francis turbines (optimized for ...Read more »

The Future Development of Micro Hydropower Plants in Uzbekistan Uzbekistan is at a pivotal moment in its energy transition. With abundant water resources, a rapidly growing economy, and ambitious renewable energy targets, the country is turning to micro and small hydropower as a strategic solutio...Read more »

As the global energy transition gathers pace, hydropower is often visualized in terms of colossal dams and sprawling reservoirs. However, a quiet revolution is occurring at a far smaller scale. Micro hydropower — systems typically generating up to 100 kW of electricity — is emerging as a compelli...Read more »

Scheduled for May 12–14, 2026, at the CAEx Uzbekistan in Tashkent, the 19th International Exhibition on Energy, Energy Saving, Nuclear Energy, and Alternative Energy Sources—Power Uzbekistan 2026—stands as a cornerstone for industry professionals. This year’s event is expected to be the largest y...Read more »

At the core of any significant hydroelectric project lies the dam—a massive engineering structure designed to obstruct the natural flow of a river. The primary function of a dam in a hydropower context is two-fold: to create a reservoir for water storage and to generate “hydraulic head̶...Read more »

The Shaft Extension Tubular Turbine, often referred to as the “S-type” tubular turbine, is a critical technology in the field of low-head hydropower generation. Unlike bulb turbines where the generator is housed within a submerged “bulb” in the water passage, the shaft ext...Read more »

Accurate measurement of head (the vertical drop of water) and flow (the volume of water passing through a system) is fundamental to the design, efficiency, and long-term performance of any hydropower project. Since the output power of a hydropower system depends directly on these two parameters, ...Read more »

Hydropower stations rely on more than just turbines and generators—stable, safe, and efficient operation depends heavily on the performance of electrical control systems. Among these, the switchgear control cabinet plays a central role in managing and protecting hydropower equipment. A switchgear...Read more »

Hydropower equipment manufacturing is a highly specialized process that combines precision engineering, advanced materials, and strict quality control to ensure reliable and efficient energy generation. From design to final assembly, each stage plays a critical role in determining the performance...Read more »
