Clean Air Markets

EmPOWER Air Data Challenge

In the EmPOWER Air Data Challenge, EPA’s Clean Air Markets Division (CAMD) is seeking proposals from academic and research institutions for practical and replicable projects using at least one CAMD dataset.

The majority of U.S. fossil fuel-fired electricity generating units submit quarterly reports on their hourly nitrogen oxides (NOX), sulfur dioxide (SO2), and carbon dioxide (CO2) emissions along with select operating parameters (e.g., hourly heat input, gross electricity generation). CAMD makes these data available through a variety of online reports and applications.

Additionally, in cooperation with the National Park Service, the Bureau of Land Management, and many other partners, CAMD operates the Clean Air Status and Trends Network (CASTNET). CASTNET data are used to assess long-term trends in air quality and deposition and provide accountability for emission reduction programs. CASTNET measures weekly gaseous (SO2, HNO3) and aerosol (SO42-, NO3-, NH4+, K+, Ca2+, Mg2+, Na+, Cl-) concentrations at more than 90 sites. Descriptions of the monitoring program, site locations, and data are available on the CASTNET website.  

Submissions for innovative and creative uses of CAMD data should advance the knowledge, use, and understanding of CAMD data and related information, with priority on the following possible project themes:

  • Analyzing data: Answer timely and relevant research questions using CAMD data
  • Enhancing communications: Design new and innovative ways (e.g. data visualizations) to present CAMD data to the public
  • Developing technology and data mashups: Develop new technologies or analytic methods to integrate CAMD data with other datasets to unlock the broader potential of CAMD data
  • Promoting environmental education: Explore opportunities to use CAMD data in high school or university classrooms
  • Improving data quality: Identify and apply algorithms (e.g., machine learning) to electronically audit CAMD data and enhance data quality

2nd EmPOWER Air Data Challenge Winners: 2020-2021 academic year

George Mason University: An accessible education tool presenting 20 years of monthly source impacts from individual coal power plants in the CAMD database

  • Researchers from George Mason, Georgia Institute of Technology, University of Texas-Austin, and ETH Zurich will analyze 20 years of CAMD's Power Sector Emissions Data and CASTNET data to assess the health benefits of the installation of pollution controls and shutdowns at coal-fired electric generating units (EGUs).​
  • Researchers will also create a public-facing data visualization tool to understand these air quality and health benefits.

University of California-Davis: Hourly Average Emissions Factors for the Emissions & Generation Resource Integrated Database (eGRID)

  • Researchers from UC-Davis and Catalyst Cooperative will use CAMD's Power Sector Emissions Data and other resources to create a database of hourly average emissions factors for eGRID and analyze how hourly emissions factors impact greenhouse gas inventory calculations.

1st EmPOWER Air Data Challenge Winners: 2019-2020 academic year

Cornell University: Predicting the Environmental Performance of Power Plants Using Machine Learning

  • Researchers applied machine learning models to CAMD's Power Sector Emissions Data to predict power plant emissions rates and identify anomalies in the data to enhance data quality.

Georgia Institute of Technology: EmPOWERing Classroom Data Engagement

  • Students created data-driven “air pollution story” websites for select facilities using CAMD's Power Sector Emissions Data.
  • Professors created a “teaching toolkit” so future classes and classes at other institutions may replicate the activity.

University of California-Berkeley/University of Oregon: Bringing Satellite Data Down to Earth: Estimating the Health Impacts of the Remarkable Decline in Coal Plant Emissions

  • Researchers worked to improve estimates of the health impacts of pollution from coal-fired power plants by using multiple data sets, including CAMD's Power Sector Emissions Data and satellite data, to causally connect pollution with health outcomes.

Benefits of Winning the EmPOWER Air Data Challenge

As a challenge winner, you will receive direct support from EPA CAMD staff experts to answer questions and assist you with CAMD tools and data analysis. In addition, you can expect to:

  • Receive national recognition for your university or organization, students, and project activities by being featured on the EmPOWER Air Data Challenge webpage and offered opportunities to speak at conferences and events
  • Collaborate with EPA and peers to advance power sector-related research and knowledge
  • Participate in special networking events and webinars
  • Improve understanding of and solve timely and relevant environmental problems
  • Gain practical experience working on environmental issues with EPA

While no funding is available for these projects, existing grants may be leveraged by participants, and we suggest that applicants reach out to their communities or other organizations for additional financial support if needed.

If you are selected as a challenge winner, we will send a memorandum of understanding (MOU) for your signature that describes project activities, deliverables, and roles and responsibilities. After signing the MOU, you should:

  • Provide regular status updates to EPA for the duration of the project
  • Prepare a summary report at the completion of the project
  • Present findings to EPA
