Data and Resources

NREL offers the following transmission integration-related data and resources.

Wind Integration Datasets

The Wind Integration Datasets provide energy professionals with a consistent set of wind profiles for the United States. These include the Eastern Wind Dataset, Western Wind Dataset, and Wind Integration National Dataset (WIND) Toolkit.

Solar Power Data for Integration Studies

The Solar Power Data for Integration Studies consist of one year (2006) of 5-minute solar power and hourly day-ahead forecasts for approximately 6,000 simulated PV plants. Solar plant locations were determined based on the capacity expansion plan for high-penetration renewables in the Western Wind and Solar Integration Study Phase 2 and the Eastern Renewable Generation Integration Study. This dataset was designed to mimic local and regional variability, variability over multiple timescales (from minutes to hours), and site-to-site correlations of solar power ramps.

Technical Review Committee Principles for Integration Studies

Working with the U.S. Department of Energy's National Renewable Energy Laboratory, the Utility Wind Integration Group has issued a set of principles for technical review committee participation in wind integration studies.
