Open Grid Emissions Initiative

Overview

This release makes 2025 Early Release data available. This is based on EIA's "early release" datasets for 2025, which do not contain the final, complete, or fully-validated versions of the data that will be released later in the fall. Based on our analysis of 2024 data, the early release version of the EIA-923 generation and fuel dataset (which is the primary input for emissions calculations) contained about 93% of the records and 98-99% of the fuel/generation of the final release data. Despite being substantially complete, EIA warns against aggregation of this early release data, so the OGE early release dataset only contains plant and subplant-level data, and no regional aggregations at this point.

This release addresses a bug that affected the completeness and accuracy of the hourly data for certain generators.
