About the data
Load, wind and solar forecasts from the seven ISOs, with every published vintage stored by publish time. Daily views show the forecast in force at each interval and at the day-ahead deadline.
History before InfraMap’s first poll is what each ISO still serves. Some ISOs keep years of vintages. Forecasts are the ISO’s, not InfraMap’s.

Known gaps
- PJM keeps 30 days of wind and solar vintages, and CAISO keeps one run per interval, so older history in those markets starts with InfraMap’s first poll.
- Forecasts are the ISO’s, not InfraMap’s.
Missing values stay missing: a null means the source has no usable record, never zero. Zero and negative values are shown as reported.
Questions it answers
- How far off was ERCOT’s wind forecast at the day-ahead deadline yesterday?
- What did MISO forecast for tomorrow’s peak load, and when was that forecast published?
- How large was the PJM solar forecast error over the last week?
