The Open Grid Emissions Initiative seeks to fill a critical need for high-quality, publicly-accessible, hourly grid emissions data that can be used for GHG accounting, policymaking, academic research, and energy attribute certificate markets. The initiative includes this repository of open-source grid emissions data processing tools that use peer-reviewed, well-documented, and validated methodologies to create the accompanying public dataset of hourly, monthly, and annual U.S. electric grid generation, GHG, and air pollution data. Data Structure data/outputs contains intermediate outputs from the data pipeline (any files created by our code that are not final results) data/results contains all final output files that will be published Release Notes The 2005-2022 data archived here was created by v0.5.0 of the Open Grid Emissions Initiative, archived on Zenodo here. For a summary of what's new in the 2005-2022 v.0.5.0 data, see the v0.5.0 release notes. Using the archived files The outputs and results files have been saved as separate zip folders for each year.
