Additional Details
BAs report generation from dual-fuel (switching from one fuel to another) and multiple-fuel (using multiple fuels simultaneously) generators under the actual energy source used, if known, and under the generator's primary energy source, if not known.
To maintain generator confidentiality, generation may sometimes be reported in the Other category if too few generators are reported for a particular energy source category.
In theory, the sum of net generation across all energy sources should equal the total net generation reported in the balancing authority operations table. In practice, there are many cases in which these values diverge significantly, which require further investigation.
In 2024Q3 EIA started using different and more granular energy source categories, particularly for renewable energy sources. The new categories differentiate between wind and solar plants that do and don't have energy storage, and split out pumped hydro from hydro without storage. They also added new battery storage and geothermal categories.
