Engineering and Technical Specifications
The Kadana Dam utilizes a composite structural design consisting of both earthen and masonry components, situated on the Mahi River in the Mahisagar district of Gujarat, India. This hybrid construction approach allows the dam to manage the hydrological characteristics of the Mahi River while supporting the requirements of the adjacent pumped-storage hydroelectric power station. The infrastructure was constructed between 1979 and 1990, with the initial phase of the power generation facilities becoming operational in 1990. The project was developed in stages, with the first two generators commissioned in 1990 and the second two generators added in 1998 to complete the installed capacity.
Power Generation Technology
The facility operates as a pumped-storage hydroelectric power station, a technology that enables energy arbitrage by storing potential energy in the reservoir during periods of low electricity demand and releasing it during peak hours. The power station employs reversible Kaplan turbines for its generation units. These turbines are specifically chosen for their efficiency in handling variable flow rates and head pressures, which is critical for the cyclical nature of pumped-storage operations. The reversible nature of the Kaplan turbines allows the units to function as both turbines for power generation and pumps for water recirculation. During peak demand periods, water flows through the turbines to generate electricity, while during low-demand periods, such as nighttime, water is pumped back into the reservoir to restore the potential energy storage.
The total installed capacity of the Kadana pumped-storage station is 240 MW. This capacity is distributed across four generator units, with the first two units commissioned in 1990 and the remaining two units added in 1998. The construction of the first stage, which included the initial two generators, was carried out by Girdharbhai Ghelabhai Mistry. The use of reversible Kaplan turbines ensures that the station can respond quickly to grid demands, making it a valuable asset for load balancing in the regional power network.

How does the pumped-storage system work at Kadana?
The Kadana Dam functions as a pumped-storage hydroelectric power station, a specific type of energy infrastructure designed to balance electrical supply and demand on the grid. This system relies on the operational flexibility of its turbine-generators, which can switch between generating electricity and consuming it to store potential energy in the water reservoir. The facility utilizes reversible Kaplan turbines, a technology particularly suited for hydroelectric plants with varying head heights and flow rates. These turbines are engineered to rotate in either direction, allowing the water flow to drive the turbine during generation and pushing water back through the turbine during pumping. The operational cycle at Kadana is divided into two primary phases: generation and pumping. During periods of peak electricity demand, typically during daytime hours when industrial and residential consumption is highest, the stored water in the upper reservoir is released. This water flows through the reversible Kaplan turbines, causing them to spin and drive the generators to produce electricity. This process converts the potential energy of the elevated water into kinetic energy and subsequently into electrical energy, feeding power directly into the grid. Conversely, during periods of low electricity demand, such as nighttime hours, the system enters its pumping phase. Electricity from the grid, often sourced from base-load power plants or variable renewable sources, is used to power the turbines in reverse. In this mode, the turbines act as pumps, drawing water from the lower reservoir or the Mahi River and pushing it back up into the upper reservoir. This process stores energy in the form of gravitational potential energy, effectively "charging" the dam for the next peak period. This cyclical operation allows the Kadana Dam to act as a giant battery for the regional power grid. By storing excess energy during low-demand periods and releasing it during high-demand times, the pumped-storage system helps stabilize grid frequency and voltage. The first two generators, commissioned in 1990 as part of Stage I, were built by Girdharbhai Ghelabhai Mistry and feature these reversible Kaplan turbines. The addition of two more generators in 1998 expanded the plant's capacity to 240 MW, enhancing its ability to manage load fluctuations. The earthen and masonry structure of the dam, constructed between 1979 and 1990, provides the necessary containment for the water reservoirs that make this energy storage mechanism possible. The system's efficiency depends on the difference in elevation between the upper and lower reservoirs, the volume of water stored, and the performance of the reversible turbines.Construction History and Key Figures
