Power Plant Data Highlights


EPA regularly posts updates of quarterly sulfur dioxide (SO2) and nitrogen oxides (NOx) emissions data from power plants subject to the Acid Rain Program (ARP), the Cross-State Air Pollution Rule (CSAPR), and the CSAPR Update 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 Market Program Data (AMPD). More summary level data is available in our Progress Reports and also in our Power Plant Emission Trends.

Annual Data and Long Term Data

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 2017 with 2018 and longer term data at the facility level. The data presented here are all final data.

Quarterly Data: 2018 vs. 2019 (Quarter 1)

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 quarterly emission data from 2018 with data for the same quarter from 2019. The data presented here are final data for 2018 and preliminary data for 2019 that are currently under review.
