Data and Resources

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

Eastern Wind Dataset

A key task of the Eastern Wind Integration and Transmission Study was to develop a dataset of three years of modeled time series wind speed and power. This dataset was designed to help energy professionals perform wind integration studies, compare potential wind sites spatially and temporally, and estimate power production from hypothetical wind plants.

Western Wind Dataset

A primary task of the Western Wind and Solar Integration Study was to produce a comprehensive dataset that could be used to model the build-out of potential wind plants in the Western United States. This dataset was designed to help energy professionals perform wind integration studies, compare potential wind sites spatially and temporally, and estimate power production from hypothetical wind plants.

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.
