With a generating capacity of 1,218 MW, Sual Power Station is the largest and most cost-effective coal-fired power plant in the Philippines. In response to the country’s needs, it was built in 1996 to ease the on-going energy crisis. The station started providing electricity to the Luzon grid in October 1999 through a 1,000 MW Energy Conversion Agreement with the National Power Corporation under a 25-year build-operate-transfer scheme.

Envisioned to be a steward in preserving the environment, Sual Power Station commits to manage the aspects of its operations that may have significant impact to the environment such as air emissions, waste water discharges, as well as solid and hazardous waste generation. This Station utilizes the best state-of-the-art environmental control technologies in the market, which are at par with the best in the world today.

Real-Time Monitoring is also being implemented to determine the efficiency of the Station’s control systems. The air, water, soil, vegetation and wildlife, as well as public health in the Station’s vicinity are constantly being monitored to ascertain their continued protection and preservation. Monitoring activities involve a Multipartite Monitoring Team composed of representatives from the DENR, local government unit, and local community and non-government organizations.

Forging strong partnerships with the local stakeholders, Sual Power Station uplift lives. At the forefront of its programs for sustainable development are its employees, sixty-six percent (66%) coming from the province of Pangasinan, of which forty-five percent (45%) are Sualinians. Through the V.I.P. (Volunteers Inspired by Partnerships) Employee Engagement Program, the employees of Sual Power Station provide a direct hand and a unified response in assisting Sualinians to realize their potentials towards self-reliance. Volunteer works include reading and computer tutorial, classroom and playground repairs, electrical connections, tree and mangrove planting, coastal clean-up, relief operations and gift-giving.

Socio-economic development is achieved through the strengthening of the eleven (11) active Multi-Purpose Cooperatives from the Station’s surrounding communities that provide contracted services vital to the plant’s continuous operations. The quality of education is being improved through construction and rehabilitation of school facilities, enhancing the capabilities of teachers, increasing access to learning materials and information technology, and granting annual scholarship awards. Provision of health services to the barangays are developed through the training program for Sual’s volunteer health workers. Fortified bread are made available to identified schools and day care centers in the villages near the station to complement the nutrition-education campaign program for mothers of malnourished children. Roads and community infrastructure are improved for sustainable development.

With its world class performance of reliability, an ISO 14001-certifiied Environmental Management Systems, and a strong partnership with its communities, Sual Power Station remains a powerful testament to TeaM Energy Corporation’s operational excellence. As Sual Power Station pledges to provide dependable and low cost energy to support the economic development of the country, endless opportunities for progress are generated, essentially creating changes that empower lives.

Operational Controls
Committed in providing the most reliable, highest quality and lowest cost clean energy in compliance with the DENR and World Bank standards, Sual Power Station operates with the following highly-efficient environmental protection equipment.

Flue Gas Desulfizer (FGD)
Reduces sulfur dioxide (SO2) from the flue gas stream before releasing it through the chimney to prevent excessive sulfur oxides in the atmosphere. This state-of-the-art pollution-mitigating equipment is the first FGD installed in the Philippines.

Electrostatic Precipitator
Acts as the vacuum cleaner of the power plant by trapping and removing fine fly ash in the flue gas up to 99.9% to prevent ash fall.

Waste Water Treatment Plant
Designed to treat all waste water coming from the power plant before discharging it to the sea to prevent water pollution.

Water Sprinkling System
Installed to eliminate coal dust during operation at the coal yard, coal unloaders and ash disposal area.

Impermeable Membrane
A high-density polyethylene (HDPE) liner at the coal yard and ash disposal site installed to prevent contamination of the groundwater.

Sewage Treatment Plant
Ensures that domestic waste water are treated accordingly to prevent water pollution.

226-m Chimney
Ensures effective dispersion of exiting flue gas with atmospheric conditions.

Continuous Emissions Monitoring System (CEMS)
Installed at the chimney to monitor SO2, NOx and particulate matter (PM) in the flue gas 24 hours a day, 7 days a week.
