Power Sector Emissions Data
EPA’s Clean Air Markets Division collects continuously monitored CO2, NOX, SO2, and mercury emissions data from electricity generating units (EGUs) to check compliance with a variety of federal air quality programs. EGUs are also required to submit operations data, facility information, monitoring plans, and quality assurance (QA) test information. These data comprise CAMD’s Power Sector Emissions Data. CAMD provides a variety of tools, detailed below, to understand and access the Power Sector Emissions Data.
Resources
Guide
- CAMD’s Power Sector Emissions Data Guide: a useful starter guide for those interested in an overview of the data available in CAMD’s Power Sector Emissions Data, how the data are collected and quality assured, and how to download the data.
Tools
- Air Markets Program Data (AMPD): a web-based application that allows you to create custom queries, view reports, and download data.
- Field Audit Checklist Tool (FACT): a Windows desktop application that allows you to view all Power Sector Emissions Data for a single monitoring location (e.g., stack).
- Field Audit Checklist Tool Application Programming Interface (FACT API): a Representational State Transfer (REST) API that was created to support the FACT desktop application and intended for those who want to access the data directly from a data tool or programming language.
- Emissions & Generation Resource Integrated Database (eGRID): a database that combines CAMD’s Power Sector Emissions Data and Energy Information Administration data in order to determine annual emissions and emission rates (lbs/MWh) at various aggregated levels in the U.S.
- Power Profiler: a web-based tool to calculate emissions from your electricity use based on eGRID data.
