Camacho said at 9 a.m., engine 6 was manually tripped as a result of problems on its cylinder head.
“The repair of the unit was immediately initiated by the plant staff and was completed at 11:55 a.m.,” he said, adding that engine 10 at Power Plant 4 suffered lube oil leakage from its crankcase compartment.
He said the unit also experienced a problem with its power pack.
Engine 10 was put back online yesterday evening, Camacho said.
The mechanical problems of engines 6 and 10 triggered double load shedding in some areas on island, but Camacho did not specify the names of these places.
“On July 22 and 23 the previously promulgated load shedding schedule was expanded to include other areas of the grid not previously scheduled,” Camacho said.
On Tuesday, engine 8 encountered a problem with its cylinder no. 16 but it was secured at 9 p.m.
Plant crews said fuel injector and exhaust valve of the engine will have to be replaced.
The cylinder head lubricator motor, according to Camacho, was repaired in the evening.
Double load shedding also occurred in some villages on Monday due to mechanical problems with the cylinder head lubricator motor of engine 6.
“The repair of the unit was immediately initiated by the plant staff and was completed at 10:10 p.m.,” Camacho stated.
Engine 6 is one of the large generators at Power Plant 1.
