Scanty rain cuts power production in U-K dams

Scanty rain cuts power production in U-K dams

The Supa, Nagajhari (Ambikanagar), Kodasalli and Kadra reservoirs across Kali river in Uttara Kannada (U-K) district have registered a fall in power generation compared to last year. This is due to scanty rainfall in the catchment areas of the Supa reservoir.

Electricity is also being produced in the Gerusoppa dam constructed across Sharavathi river in Honnavar taluk in the district. There has been a reduction in rainfall in the catchment areas of the Gerusoppa reservoir too.

The inflow into the Supa reservoir in August last year was 15,000-20,000 cusecs. This time, it has reduced to 6,000-8,000 cusecs. The priority now is to maintain the storage levels in the dams, rather than to generate power. The Karnataka Power Corporation (KPC) has a target to produce 4,196 million units (mu) of power every year from the four dams across the Kali. It had exceeded the target by generating 4,456 mu in 2014-15. The reservoir-wise break-up is: Nagajhari (3,223 mu), Supa (448 mu), Kadra (400 mu) and Kodasalli (385 mu).

e district was 406 mu. But KPC was able to generate a mere 148.757 mu, with only the hydel units at Supa exceeding the target. There are six hydel units at the Nagajhari dam, two in Supa, three each in Kadra and Kodasalli. Electricity is generated based on the demand in these units. The rainy season demand is usually less.

Power is produced in the Supa dam till the water level is 513 meters or more, K V Chalapathy, chief engineer of KPC, told Deccan Herald. However, he assures that there is nothing to worry on the power generation front, though the rain in the catchment area has reduced.

Supa dam 2nd largest in State

The Supa dam is the second largest in the State, with a height of 101 meters and a length of 332 meters. The command area is 1,057 sq km and the storage capacity is 145 tmc ft. The maximum water level here is 564 metres. Its power generation unit has two turbines of 50 MW each and they can generate 542 mu of power a year.
