The Aboitiz Group is the country’s biggest power producer, based on July 2025 data from the Energy Regulatory Commission (ERC). It was followed by San Miguel Corporation.
Together, the two conglomerates generate close to half of the country’s power supply.
Their fuel of choice: coal. It is the single largest source of carbon dioxide emissions, which triggers global warming and extreme weather such as stronger typhoons, heavier floods, and prolonged droughts.
Coal-fired plants make up more than 60% of the facilities operated by San Miguel Global Power, according to its 2024 annual report. The Aboitiz Group, meanwhile, reported that coal accounted for 48% of its total net sellable capacity as of May 2025. Together with gas, fossil fuels made up at least 75% of the total capacity of both companies.
