Palo Seco Gas Power Plant | Puerto Rico, United States

Palo Seco is a gas-fired power plant situated in Puerto Rico, a territory of the United States. With a capacity of 126 MW, it falls within the medium-scale range for gas power plants. The facility is operational and contributes to the local power grid. The plant operates under the regulatory framework of the United States, including the Clean Air Act (CAA) and associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Cross-State Air Pollution Rule (CSAPR). Gas-fired plants generally have lower emissions of sulfur dioxide (SO2) and particulate matter compared to coal-fired units, but still require compliance with emission limits for nitrogen oxides (NOx) and other pollutants. As a gas-fired facility, Palo Seco provides flexible generation capacity that can support grid stability and integrate renewable energy sources. Its location in Puerto Rico is significant for meeting the island's electricity demand, and the plant's operational status ensures continued service to the community.

The plant's gas-fired technology results in lower CO2 emissions per MWh compared to coal or oil, but still contributes to greenhouse gas emissions. Proximity to populated areas may raise local air quality concerns, particularly for NOx. Typical gas plants in the region operate with modern emission controls.
