Business Operations

Semirara Mining and Power Corporation is engaged in thermal coal extraction and power production. Our common stock is listed on the Philippine Stock Exchange under the symbol “SCC”.

Coal Operations

SMPC's surface open cut mining operations is based in Semirara Island in the province of Antique. Covering an area of 55 square km, Semirara Island is located 350 km south of Manila.


On 20 November 1940, President Manuel L. Quezon issued Proclamation No. 649 declaring the islands of Semirara, Sibay and Caluya in Antique as coal mining reservation.  This allowed for the issuance of Coal Operating Contracts (COCs) in Semirara Island to SMPC, with its COC expiring on July 14, 2027. Today, the island continues to be the largest known coal reserve and operational coal mine in the country.


SMPC’s coal is classified as sub-bituminous-B, and appropriate for use in a wide range of combustion facilities. Taking advantage of its strategic location and market position as the largest coal producer in the Philippines, our coal is sold domestically to power plants, cement plants, paper mills, textile dying plants, and canneries, among others.


In 2007, we successfully forayed into the export market with its maiden shipment to China. Since then, we have expanded our market base to include India, Japan, Thailand, Brunei, Cambodia, Vietnam, and South Korea.

Power Operations

Through our wholly-owned subsidiaries, SMPC operates four units of coal-fired power plants in Calaca, Batangas, with a total of 900-megawatt (MW) installed capacity.


Sem-Calaca Power Corporation (SCPC)


On August 3, 2009, DMCI Holdings Inc. (DMCI-HI) ventured into power generation after it acquired the two units of 300MW coal-fired power plants in Calaca, Batangas from the Power Sector Assets and Liabilities Management Corporation (PSALM). The strategic investment was an excellent opportunity to protect the coal market of what was then Semirara Mining Corporation (SMC) since the Calaca power facility was designed for Semirara coal.


SCPC was incorporated on November 19, 2009, to acquire, design, construct, rehabilitate, expand, and maintain power-generating plants and related facilities for the generation of electricity, including the sale of electricity to any person through electricity markets, among others. The two units underwent rehabilitation and retrofitting to arrest their deterioration and improve their operational efficiency, allowing SCPC to deliver additional, much-needed power to the main grid.


DMCI-HI decided to fold SCPC into SMC since the former sourced its fuel from the latter. The plant's proximity to Semirara Island, Antique resulted in significant cost savings on freight expenses as compared to importing coal, which eventually commanded greater value. 


Southwest Luzon Power Generation Corporation (SLPGC)


SLPGC was incorporated on August 31, 2011, to acquire, design, develop, construct, expand, invest in, and operate electric power plants, and engage in the business of a Generation Company in accordance with RA No. 9136, otherwise known as Electric Power Industry Reform Act of 2001 (EPIRA).


SLPGC is located in the municipalities of Calaca and Balayan in the Province of Batangas, adjacent to the existing 2x150MW Power Plant owned by its affiliate, SCPC. Situated near Metro Manila, Batangas Port, and several industrial parks in the area, SLPGC is strategically positioned to cater to the electricity needs of its host communities and major power consumers and industrial companies.


SLPGC currently operates 2X150MW Coal-Fired CFB power plants. An expansion capacity project is in the pipeline to further increase installed capacity to an additional 700MW under St. Raphael Power Generation Corporation (SRPGC). The power plant investment in Batangas is a testament to SMPC's commitment to contribute to the country's energy security and economic development.
