ALAPPUZHA: The National Thermal Power Corporation’s warning that it will be compelled to shut down its Kayamkulam plant bore fruit as the major irrigation department started pumping water from Kakkad dam to the Achankovil River.

The NTPC had on Monday said it would down shutters in three days due to the non-availability of clean water. The high salinity level in Achankovil waters had threated the functioning of the plant.

The salinity level started decreasing as Kakkad water flowed into Achankovil on Tuesday. NTPC officials told TOI that if the situation continued the plant could function without disruption.

T C Anilkumar, deputy general manager (technical services) of the NTPC said the salinity level in the river was 700 microsiemens per centimeter on Monday. “It has dipped below 500 microsiements per centimeter on Tuesday and we can continue generating power if salinity level comes down to 400 microsiemens per centimeter,” he said.

The irrigation department, meanwhile, has commenced the construction of a bund at Kavumbattu. We will complete the construction within two days and it will prevent seawater from entering the river,” said major irrigation executive engineer R Venugopal.

The NTPC depends on Achankovil river for producing electricity from naphtha. The plant requires 18,000 kilolitre of water daily to generate power.

NTPC unit general manager C V Subramanian had on Monday said that the plant would be shut down due to high saline level. Though the plant has the capacity to produce 300MW of power daily, the output has been halved due to water scarcity.
