With heavy rainfall in the catchment areas, 313.74 million units of electricity was generated at Ukai dam in August and September, the second highest during the period in the last six years.
According to Ukai dam authorities, 184.702 MU was generated at the dam in 2020, 134.339 MU in 2021, 356.976 MU in 2022, 160.930 MU in 2023, 244.11 MU in 2024 and 313.74 MU in 2025 in August and September.
Sources stated that the hydro turbines operate while discharging water from the dam, which has a catchment area of approximately 62,285 sq km of which around 52,000 hectares is in Maharashtra and Madhya Pradesh. The majority of its catchment area lies in Maharashtra.
According to the Ukai Dam authorities, the inflow into the dam began on June 18, following heavy rainfall in the upper catchment areas of the dam.
The dam has received 11,144 million cubic meters of water and 8,000 MCM of water has been discharged this year. The water discharged from the dam reaches the Tapi River and flows into the sea at Dumas in Surat. The dam authorities started operating four hydro turbine units on August 18.
With the rainy season still underway and many parts of Maharashtra and Madhya Pradesh continuing to receive rainfall, the figures may go up, said Ukai officials.
On Thursday, the water level at the dam was 344.85 feet, just below the danger level of 345 feet and the rule level of 345 feet. This means that now no more water can be filled into the dam.
The gross storage of the dam is 7,387.58 MCM (million cubic meters), while the live storage is 6,703.19 MCM, which is approximately 90.40 per cent.
On Thursday afternoon, the inflow of water into the dam was 46,421 cusecs and outflow was 11,498 cusecs, out of which 10, 398 cusecs was through hydroelectric power generation and 1,100 cusecs through canals for irrigation.
Deputy Executive Engineer of Ukai Dam G S Kokani said, “During the monsoon season, the maximum power is generated through four hydro power turbines, each of 75 MW capacity. The hydro turbines operate at maximum capacity in August, September and October. In the three months in 2022, we have generated 510.822 MU. This year, in August and September, we have generated 313.740 MU. We are hopeful of clocking a record this year, as the rainfall continues in the catchment areas of Maharashtra and Madhya Pradesh.”
Constructed in 1972 across the Tapti River, the dam is meant for irrigation, power generation and flood control.
