Meralco seeks FGen supply
Manila Electric Co., the biggest retailer of electricity, is negotiating with First Gen Corp. to buy 200 megawatts from the latter’s 414-megawatt San Gabriel natural gas plant in Batangas to ensure adequate power supply during the dry months.

First Gen Corporation (First Gen) hereby advises the Exchange of the status of First Gen’s power plants
following the magnitude 5.6 and 6.0 earthquakes and aftershocks that hit Mabini, Batangas in the
afternoon of April 8, 2017. These are the 1000 MW Santa Rita, 500 MW San Lorenzo, 414 MW San
Gabriel, and 97 MW Avion natural gas-fired power plants, all of which are located within the First Gen
Clean Energy Complex in Batangas City.
The 1000 MW Santa Rita power plant tripped following the earthquakes. Based on preliminary
assessment, the Santa Rita plant did not suffer any significant damage, and has since resumed
On First Gen’s other plants, preliminary inspections indicate that the San Lorenzo, San Gabriel and
Avion power generating units sustained no damage from the earthquakes that can prevent these plants
from operating. The earthquakes, however, damaged various components of the San Lorenzo
Switchyard. Since the San Lorenzo Switchyard connects the San Lorenzo, San Gabriel and Avion power
plants to the transmission lines of the National Grid Corporation of the Philippines (NGCP), no power
from these plants can currently be exported to the grid. In cooperation with Siemens Power Operations
Inc. (SPOI), the Operations and Maintenance (O&M) contractor for the San Lorenzo and San Gabriel
power plants, the company is already working on an interim solution to restore operability of the San
Lorenzo Switchyard and enable resumption of operation of the San Lorenzo, San Gabriel, and Avion
First Gen will advise the Exchange of any material development in this regard.

From the FGEN disclosure posted by lep_33 above ^ ...
Interesting. A switchyard without moving parts is damaged while the power plants with rotating
machinery are not. My guess: collapsed steel gantries that support the EHV bus conductors.

"According the name 'investors' to institutions that trade actively is like calling someone who repeatedly engages in one-night stands a 'romantic.'"
When the disclosure says "various components" are involved, it implies a common-mode cause of
failure. And when they say that "Siemens is working out an interim solution", that means that re-
storation works will take some time. If the failure only involved individual switching equipment, ie.,
disconnect switches or circuit-breakers, there is enough redundancy in EHV switchyards to mitigate
a whole-sale shutdown of three (3) power plants.
The problem is something else --- it is not the take-off power transformer(s) because various equip-
ment were involved. My guess: the steel gantries collapsed and damaged a number of switching
equipment. Hopefully, nothing fell on the power transformer(s).
Luzon power supply back to normal
The Energy Department on Monday said power supply in Luzon has returned to normal with the entry of the Malaya thermal power plant in Rizal and some natural gas plants into the grid.
“We are no longer on yellow alert because there is enough supply. The plants have started to go online,” Energy Undersecretary Felix William Fuentebella said in a radio interview.
Fuentebella said Luzon had an available power supply of 10,797 megawatts as of Monday, reflecting adequate reserves against demand of about 8,700 MW to 9,000 MW.
He said power plants that came online included Malaya 1, 150 MW; Ilijan, 600 MW; Sta. Rita, 250 MW; and San Lorenzo, 250 MW.
Supply from the natural gas plants in Batangas were disrupted after the April 8 earthquake, resulting in a loss of over 1,000 MW from the Luzon grid.
“We are exerting all efforts to enable Unit 50 (of San Lorenzo), San Gabriel, and Avion to export their outputs within the coming days. Our site management team and our contractors have been tirelessly working since last week including through the Holy Week break,” First Gen Corp. vice president Jerome Cainglet said.
First Gen owns the 1,000-MW Sta. Rita, 500-MW San Lorenzo, 414-MW San Gabriel and 10- MW Avion natural gas plants.
First Gen last week said while the power plants did not suffer damage from the earthquake, it destroyed various components of the San Lorenzo switchyard.
Since the San Lorenzo switchyard connects the San Lorenzo, San Gabriel and Avion power plants to the transmission lines of National Grid Corp. of the Philippines, no power supply from these plants were exported to the grid.
First Gen said the company, along with Siemens, the operations and maintenance contractor of the San Lorenzo and San Gabriel plants, was working on an interim solution to restore the operability of the switchyard and enable the operation of the power plants.
First Gen: 500-MW Batangas gas plant is now back on line
By Lenie Lectura - April 18, 2017
THE Lopez-led First Gen Corp. on Tuesday said a unit of the 500-megawatt (MW) San Lorenzo gas plant in Batangas is now back on line and is working on to reconnect other gas plants to the Luzon grid.
“We are exerting all efforts to enable Unit 50 [of San Lorenzo], San Gabriel and Avion to export their outputs within the coming days. Our site management team and our contractors have been tirelessly working since last week, including through the Holy Week break,” First Gen Vice President Jerome Cainglet said.
First Gen is currently repairing the San Lorenzo Switchyard (SL Switchyard), following the earthquake that hit Batangas on April 8.
The switchyard connects First Gen’s three natural gas-fired power plants—the 500-megawatt (MW) San Lorenzo, 414-MW San Gabriel and 97-MW Avion power plants—to the transmission lines of the National Grid Corp. of the Philippines.
Of the two 250-MW units (Units 50 and 60) of the San Lorenzo power plant, the connection of San Lorenzo Unit 60 to the grid has been restored. Unit 60 was resynchronized to the grid and has resumed operations.
First Gen said it continues to exert efforts with the aim of restoring the grid connection through the SL Switchyard to enable San Lorenzo Unit 50, as well as San Gabriel and Avion, to export its output to the grid in the coming days.
While the 1,000-MW Santa Rita power plant tripped following the earthquakes, preliminary assessment showed the plant and the Santa Rita switchyard did not suffer any significant damage. The plant has since resumed operations.
Further to our April 17, 2017 disclosure on the interim solution pursued by First Gen Corporation (First Gen) to restore operability of the San Lorenzo Switchyard which connects First Gen’s 3 natural gasfired power plants to the transmission lines of the National Grid Corporation of the Philippines, we are pleased to advise that the connection to the grid of the 500 MW San Lorenzo, 414 MW San Gabriel, and 97 MW Avion power plants has been restored. Accordingly, power output from all 3 power plants can now be exported to the grid.
