Power Plant Data Highlights


EPA regularly posts updates of quarterly sulfur dioxide (SO2), nitrogen oxides (NOx), carbon dioxide (CO2), and mercury (Hg) emissions data from power plants subject to the Acid Rain Program (ARP), the Cross-State Air Pollution Rule (CSAPR), the CSAPR Update, and the Mercury and Air Toxics Standards (MATS) to make it easy for the public to track changes in emissions from these sources.  All of the data presented here are also available in Air Markets Program Data (AMPD). More summary level data is available in our Progress Reports and also in our Power Plant Emission Trends.

Annual Data: 2018 vs. 2019

The data presented here compare emissions, emission rates, and heat input from power plant units in the ARP, CSAPR, and CSAPR Update. These files compare annual emission data from 2018 with 2019 and longer term data at the facility level.

Quarterly Data: 2019 vs. 2020 (Quarter 1)

The data presented here compare emissions, emission rates, and heat input from power plant units in the ARP, CSAPR, CSAPR Update, and MATS. These files compare quarterly emission data from 2019 with data for the same quarter from 2020.

Ozone Season Data: 2018 vs. 2019

The data presented here compare emissions, emission rates, and heat input from power plant units in the ARP, CSAPR, CSAPR Update, and MATS. These files compare ozone season emission data from 2018 and 2019.

Facility Level Emission Changes: 2009 vs. 2019

The data presented here compare emissions and emission rates from power plants in the ARP, CSAPR, and CSAPR Update. These files compare longer-term annual data at the facility level.
