6 FAQs about [Western wind and solar power generation]

What is the western wind & solar integration study NREL?

The Western Wind and Solar Integration Study NREL is a national laboratory of the U.S. Department of Energy, Office of Energy Efficiency & Renewable Energy, operated by the Alliance for Sustainable Energy, LLC. This report was prepared as an account of work sponsored by an agency of the United States government.

How does wind/solar generation affect WestConnect?

Increased wind/solar generation in the rest of WECC (20/20% case) led to increased stress on system operations within WestConnect, with some instances of insufficient reserves due to wind and solar forecast error. These can be addressed, but the system has to work harder to absorb the wind/solar.

Will 35% wind and solar energy be integrated into the electric power system?

The integration of 35% wind and solar energy into the electric power system will not require extensive infrastructure if changes are made to operational practices. Wind and solar energy displace fossil fuels.

How can wind and solar energy be used to reduce variability?

Increasing the size of the geographic area over which the wind and solar resources are drawn substantially reduces variability. Scheduling generation and interchanges subhourly reduces the need for fast reserves. Using wind and solar forecasts in utility operations reduces operating costs by up to 14%.

Does wind and solar variation affect net load?

In the July week, (left plot), the net load (blue line along bottom edge) is not significantly impacted by wind and solar variation. However, in the April week (right plot), the high, variable wind output dominates the net load, especially during low load hours, leading to several hours of negative net load during the week.

Will wind and solar power replace fossil fuels?

Wind and solar energy displace fossil fuels. A 35% penetration of solar and wind power would reduce fuel costs by 40% and carbon emissions by 25%–45%—the rough equivalent of taking 22–36 million cars off the road—compared to today's system.
