Power Sector Emissions, Operations, and Environmental Data
EPA’s Clean Air Markets Division (CAMD) has monitored and collected emissions and operating data from power plants since 1990. CAMD has also gathered ambient data to track changes in the environment since the mid-1980s.

CAMD's EmPOWER Air Data Challenge
Each academic year, CAMD hosts a challenge inviting researchers at universities or think tanks to submit innovative ideas for use of CAMD’s Power Sector Emissions Data, Clean Air Status and Trends Network (CASTNET) data, and Long Term Monitoring Network (LTM) data.
Current Status: The application period for the 3rd annual EmPOWER Air Data Challenge is now closed. Winners will be announced this spring.
