Time-Coincident Load, Wind, and Solar Data for Four U.S. Grid Regions

5-minute resolution time-coincident load, wind, and solar data includes actual and probabilistic forecasts for the ERCOT, MISO, NYISO, and SPP grid regions. Wind and solar profiles cover existing sites and planned sites from the 2021 interconnection queue. The datasets were produced by the National Renewable Energy Laboratory (NREL) for the ARPA-E PERFORM project.

Use Cases

• Train probabilistic forecasting models using 5-minute resolution load, wind, and solar data to predict grid delivery risk.
• Analyze time-coincident relationships between actual and forecasted solar and wind generation across four independent system operators (ISOs).
• Model the impact of planned interconnection queue projects from 2021 on future grid generation profiles using supplied wind and solar site data.
• Compare actual load and generation data from 2017-2019 against probabilistic forecasts to validate forecast accuracy for specific ISOs.

Strengths

• 5-minute temporal resolution provides high granularity for grid analysis.
• Includes data for four major U.S. grid regions: ERCOT, MISO, NYISO, and SPP.
• Covers both actual historical data and probabilistic forecasts for comparative analysis.
• Profiles include planned generation sites based on the 2021 interconnection queue, supporting forward-looking studies.

Limitations

• Actual data coverage is limited to 1-2 years per region (e.g., 2017-2018 for ERCOT).
• Forecast data is only provided for single years (2018 or 2019), limiting longitudinal forecast evaluation.
• The primary data format is HTML, which may require significant parsing to extract structured data for analysis.
