The 1,216 MW Sual Coal-Fired Thermal Power Plant


The Sual Coal-Fired Thermal Power Plant in Sual, Pangasinan, Philippines, has an installed capacity of 1,216 MW. It is composed of two (2) generating units with a gross capacity of 618 MW each, making Sual to have the largest generating unit in the Philippines. (NOTE: Santa Rita Combined Cycle Power Station in Batangas is the largest power plant in the Philippines in terms of total plant capacity. Total plant capacity is 1,500 MW, six units of 250 MW).

The criticality of running the largest generating units in the grid was proven on Dec. 10, 1999 when the Luzon Grid collapsed due to the tripping of the Sual generating units due to alleged “jelly fish” attack that plugged the plant’s circulating cooling water.

The Plant was commissioned on March 1999 (Unit 1) and June 1999 (Unit 2). It is owned and operated by TEAM Energy, the consortium of Tokyo Electric and Marubeni. It was previously owned and operated by Mirant Sual Corporation (Hopewell) or formerly CEPA Pangasinan Electric Limited. It is an Independent Power Producer (IPP) of the National Power Corporation (Napocor) under a Built-Operate-Transfer (BOT) – Energy Conversion Agreement (ECA) Contract. Project cost is around US1,200 Million.

The Plant has been criticized for having low capacity factor or under-utilized though its contracted capacity is around 1,000 MW. However, it is justified since the Plant is usually used as a spinning reserve of the Luzon Grid.
