Available packages

Real contents of the current builds — row counts, sizes and checksums come from the packaging manifest, not estimates.

Built from the EIA official bulk files: hourly grid operations for every US balancing authority since 2015 (demand, generation, interchange, fuel mix), EIA-860 plant/generator/utility master data, EIA-923 plant-level monthly generation 2017-2025, and state-level retail electricity prices and generation.
