MANILA, Philippines - Unit 20 of the
1,000-megawatt (MW) Sta. Rita combined cycle power plant has resumed operations
ahead of target after the replacement of its damaged transformer, Lopez-led
First Gen Corp. said.
In a disclosure to the Philippine
Stock Exchange, First Gen said it has replaced the unit’s damaged main
generator with the spare main transformer.
Investigation showed the main
transformer was damaged after a fault occurred during its one month scheduled
maintenance outage from July 23 to Aug. 26.
First Gen earlier said Unit 20 was
supposed to come back online in the first week of October after deploying the
spare main generator transformer stored within the site.
Unit 20, which has a capacity of 250
MW, is one of four units of the Santa Rita power plant in Batangas owned and
operated by First Gen subsidiary First Gas Power Corp. (FGPC).
Unit 20 of the Sta. Rita plant was
among the nine power plants that went offline when a series yellow and red
alerts were raised in the Luzon grid by the National Grid Corp. of the
Philippines (NGCP) from July 25 to 29.
A yellow alert means means that
contingency reserves are below the minimum level set by the regulator but does
not necessarily lead to power outages.
The Department of Energy (DOE) asked
the Energy Regulatory Commission (ERC) to investigate whether power players
employed anti-competitive behavior which led to deficient power supply during
the period.
The DOE has also initiated the
formation of technical audit teams which will validate the figures submitted by
the generating companies and the distribution utilities which will be used in
the delivery of quality, reliable, secure and affordable supply of energy.
