The Ilijan Power Plant sits on a 60-acre site at Arenas Point, Barangay Ilijan, Batangas City and was constructed and is owned by KEPCO (through its local subsidiary, KEPCO Ilijan Corporation) pursuant at a 20-year ECA with NPC under a BOT scheme that expires or June 4, 2022.
NPC supplies gas to the Ilijan power plant from the Malampaya field in Palawan. The Ilijan Power Plant consists of two blocks with a rated capacity of 600 MW each. The power plant can also run on diesel oil stored on site.
On April 16, 2010, SMC successfully bid for the appointment to be the IPPA for the Ilijan Power Plant and received a notice of award from PSALM on May 5, 2010. On June 10, 2010, SMC and SPPC (Ilijan) entered into an Assignment Agreement with Assumption of Obligation whereby SMC assigned, with the consent and conformity of PSALM, all of its rights and obligations under the Ilijan IPPA Agreement to SPPC administration of the Ilijan Power Plant.
