With rains in the past few days leading to a rise in water level in the dams in the district, Kerala State Electricity Board (KSEB) has increased power generation at power stations in Idukki and Edamalayar to their maximum capacities.
The water level in Idukki reservoir on Wednesday was 2,364.24ft which is 32ft higher compared to same day last year. The water-level in the reservoir in the same day last year was 2,332.74 ft. The powerhouse generated 14.816 mu of electricity on Tuesday. For the shutters of the dam to be opened the water-level has to rise 16ft more, said officials.
“Presently, the water level in the reservoir is over 10 feet below the ‘rule level’. The ‘rule level’ till August 1 has been fixed at 2,380.58 ft. KSEB called a review meeting and decided to increase the power generation in Idukki and Edamalayar dams,” said Supriya S, KSEB chief engineer (dam safety and DRIP).
“The ‘rule curve’ was fixed after considering the monsoon pattern. But the unexpected rains have led the water-levels in the reservoirs to rise. Every 10 days KSEB, district disaster management authority, district collector and water resource department review the situation in the dams. When water levels rise to the ‘rule level’, we will immediately release the water to provide ‘flood cushion’ in the dams,” said the official.
A KSEB official said that the storage levels in hydel dams are higher due to lower power generation.
