The Kerala State Electricity Board resumed power generation at the Moozhiyar power house of the Sabarigiri hydro-electric project for a few hours, after completing the repair and maintenance works ahead of schedule, in order to meet the peak load demand on Thursday evening, Mohamed Ali Rawther, Deputy Chief Engineer at Moozhiyar, said.

However, power generation at Moozhiyar will be stopped on Friday morning to facilitate repair works at the 50 MW Kakkad power house that operates with the tailrace water of the Sabarigiri project.

The power houses were shutdown on February 5 to facilitate major repair and maintenance works.

Mr. Rawther told The Hindu that debris and external particles accumulated in the Moozhiyar reservoir of the Kakkad project were removed the other day.

He said replacement of the damaged seals of the butterfly valves (inlet valves) at the upstream and downstream ends of the generator one at the Kakkad power house had been completed and the seal replacement work on the second generator too would be completed by Friday evening.

A newly designed cooling water pump strainer was installed at the tailrace of the power house after draining out water with a view to restricting entry of external particles into the generator and the turbine cooler system, thereby increasing the efficiency of the generators, he said.

In two days

Mr. Rawther said the Moozhiyar power house would remain shut till the completion of the repair work at Kakkad to avoid spillage at the Moozhiyar dam. One of the two generators at the Kakkad power house would be ready for operation in the next two days.

“The KSEB is likely to partially resume power production at both the power houses in the next two days itself,” he added.

He said complete maintenance was carried out at the valve house as well as the upper and lower switchyards of the Moozhiar power house.
