Power Plants and Neighboring Communities Map

The Power Plants and Neighboring Communities (PPNC) web mapping tool is an interactive mapping tool that displays socioeconomic information (i.e., people of color, low-income, unemployment rate, limited English speaking, less than high school education, under age 5, and over age 64), along with the location and operating information for fossil fuel-fired power plants. 

The PPNC webmap is used in the PPNC web mapping tool and is available on EPA's GeoPlatform. 

The eGRID power plant information is presented via map images and mapping applications. 

The data includes environmental characteristics, emissions, emission rates, generation, heat input (e.g. energy from combustion), and many other attributes for all grid-connected electric generating units (EGUs) at facilities that have a nameplate generating capacity of at least 1MW.

The data includes annual emissions and heat input. The data is collected by EPA under the regulations in 40 CFR Part 75. Other available data includes hourly emissions and operating parameters plus facility information and testing results.

EJScreen is EPA's environmental justice mapping and screening tool that provides EPA with a nationally consistent dataset and approach for combining environmental and socioeconomic indicators.

This feature layer contains data for the following map layers:

1. Combustion Power Plants displays power plants with the markers color-coded according to the national percentile of the demographic index .
2. Emissions displays power plants with the size of the markers corelating to the annual emissions of SO₂, NO_X, CO₂,and PM_2.5 in tons.
3. Fuel Types displays power plants with the markers color-coded according to fuel type.

A file that compiles US Energy Information Administration (EIA) power plant data from the Preliminary Monthly Electric Generator Inventory and the Electric Power Monthly and displays recent and expected power plant retirements through 2030.

This group of layers includes:

• 3-Mile Buffers
  • Displays the three mile buffers around each power plant. Populations within the three mile radius are included in the socioeconomic summaries. 
• Block Group Boundaries  from the EJSCREEN_Indexes feature layer.
• Socioeconomic Indicators from the ejscreen/socioeconomic_indicators_2023_public MapServer:
  • Demographic Index
  • Supplemental Demographic Index 
  • People of Color
  • Low Income
  • Unemployment Rate
  • Limited English Speaking
  • Less Than High School Education
  • Under Age 5 
  • Over Age 64

More information about the socioeconomic indicators can be found on EJScreen's Overview of Socioeconomic Indicators webpage. 

This  layer presents US census tracts classified as disadvantaged by:

• CEJST Justice40 Disadvantaged Communities and 
• EPA IRA Disadvantaged Communities

This group of layers includes:

• American Indian Reservations
• Plants within 50 miles
