Background
Mariveles Power Plant is a two-unit, 690-megawatt (MW) coal-fired power station on the Bataan Peninsula, on the island of Luzon in the Philippines, owned by GNPower.[1] [2] The project consists of two 345 MW units using subcritical boilers. The plant went online in April 2013.[3]
As of April 28, 2023, the DOE's list of existing power plants in Luzon had updated the installed capacity of the plant to 2 x 325.8 MW (651 MW), and the dependable capacity to 2 x 316 MW (632 MW).[4]
In December 2023, a fire broke out at the power station after the spontaneous combustion of coal in a storage area at the plant. Both units at the plant were temporarily shut down.[5]
Regarding the future operations of the Mariveles Power Plant in light of the G7 proposal to phase out coal power, commentary from Aboitiz Power in 2024 did not indicate that the power station owner planned to retire the power station in the near future.[6]
Ownership
The plant's owner, GNPower Mariveles Coal Plant Ltd., is jointly owned by U.S. company Sithe Global Power (owned by the Blackstone Group) and the Philippine Ayala Corporation; Ayala acquired a 17.1 percent state in the project for $155 million in December 2012.[7][8]
In October 2016, the Philippines' Aboitiz Power acquired stakes held by Blackstone Group LP for US$1.2 billion.The acquisition involves a 66.1 percent indirect interest in both the Mariveles plant and its expansion.[9] In May 2019, Aboitiz acquired Ayala's shared of the project, giving it a total ownership stake of 78.3%.[10]
Description of Expansion
In 2013, plant owner GNPower said it planned to expand the power station. For more information, see Dinginin power station.
Financing
In January 2010, China Development Bank provided a US$493 million direct loan for the project, which the China Export and Credit Insurance Corporation guaranteed. Citigroup, BDO Unibank, and Standard Chartered Bank provided an additional US$227 million in loans. Denham Capital Management, PMR Holding Corporation, Power Partners, and Sithe Global Power provided US$280 million in equity. Total financing amounted to just over US$1 billion.[11]
Environmental impacts
According to reporting from February 2025, the development of the Mariveles Power Plant and the Dinginin power station in the Bataan special economic zone on Manila Bay had caused significant environmental damage to the local marine ecosystem. Local fishers and residents had reportedly seen reduced catches and suffered health effects from air and water pollution, and alleged that they had not been informed about GNPower’s air and water testing results.[12]
