The Solar Power Data for Integration Studies are synthetic solar photovoltaic (PV) power plant data points for the United States for the year 2006. They consist of one year of five-minute solar power and hourly day-ahead forecasts for approximately 6,000 simulated PV plants. The data are intended for use by energy professionals such as transmission planners, utility planners, project developers, and university researchers who perform solar integration studies and need to estimate power production from hypothetical solar plants.
