Of the P5.9 billion remitted by SMPC, more than P3.5 billion will be retained by the national government. In accordance with the law, the rest will go to the host local government units of the SMPC mine site, with the province of Antique receiving P476 million while the municipality of Caluya and Barangay Semirara receiving around P1.1 billion and P833 million, respectively. The Local Government Code of 1991 entitles local government units to a 40 percent share of royalty proceeds from petroleum, coal, geothermal, hydrothermal and wind resources. SMPC is the only vertically-integrated power generator in the country that produces its own fuel. As the largest domestic coal producer, it supplies affordable fuel to power plants, cement factories and other industrial facilities across the Philippines.
