SEMIRARA Mining and Power Corp. (SMPC) said on Monday that the first 300-megawatt (MW) unit of its two-unit coal-fired thermal power plant in Calaca, Batangas has resumed operations.

Another SMPC subsidiary, Southwest Luzon Power Generation Corp. (SLPGC), earlier reported that the 150-MW unit one of its two-unit coal-fired circulating fluidized bed thermal power plant near Sem-Calaca had an unplanned outage beginning March 6.

The second 150-MW is undergoing regular planned maintenance. It is expected to be online by the last week of the month.
SMPC said both subsidiaries鈥 outages are still within allowable limits, and the group would not need to provide replacement power.
