Power Plants and Neighboring Communities Web Mapping Tool
The Power Plants and Neighboring Communities (PPNC) web mapping tool is an interactive mapping tool that displays key community demographics (low-income population, people of color, population with less than high school education, linguistically isolated population, population under age 5, and population over age 64), along with the location and operating information for fossil fuel-fired power plants.
Power Plants and Neighboring Communities Web Map
The PPNC webmap is used in the PPNC web mapping tool and is available on EPA's GeoPlatform.
Data Sources
PPNC combines power plant data with demographic data from EJSCREEN. The power plant data is from the following two data sets available from EPA's Clean Air Markets Division (CAMD):
Emissions & Generation Resource Integrated Database (eGRID)
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.
Power Sector Emissions Data
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.
Map Layers
Power Plants and Neighboring Communities (2021)
This feature layer contains data for the following map layers:
- Combustion Power Plants displays power plants with the markers color-coded according to the national percentile of the demographic index .
- Emissions displays power plants with the size of the markers corelating to the annual emissions of SO2, NOX, CO2,and PM2.5 in tons.
- Fuel Types displays power plants with the markers color-coded according to fuel type.
3-mile Buffer
Displays the three mile buffers around each power plant. Populations within the three mile radius are included in the summary demographics.
Power Plant Retirements
