Calaca SLTEC Power Plant280 MW Coal

CoalVerified: Feb 2026

The Calaca SLTEC Power Plant plays a vital role in the energy landscape of the Philippines, contributing significantly to the national energy mix with its 280 MW capacity. Operated by South Luzon Thermal Energy Corp., this coal-fired power generation facility is strategically located near the coast at coordinates 13.9193, 120.8264, which enhances its accessibility to essential infrastructure and resources. As the Philippines continues to balance its energy needs with environmental considerations, the Calaca SLTEC Power Plant serves as a crucial source of baseload power, ensuring reliable energy supply for the Luzon grid. Coal remains a predominant fuel type in the country's energy generation strategy, providing a stable supply amidst the growing push for renewable energy sources. The technology employed at Calaca is based on conventional coal combustion, which, while efficient, is increasingly scrutinized within the context of global climate commitments. As the Philippines aims to diversify its energy portfolio, facilities like Calaca highlight the transitional phase the country is navigating, balancing energy security with sustainability. The plant's operational context is further shaped by evolving energy policies that encourage investment in cleaner technologies while still relying on established coal generation to meet immediate demand.
