The western wind and solar integration study phase 2

1st September 2013

Topic(s): Renewables, Engineering and project delivery, Economics

This report describes the findings of a National Renewable Energy Laboratory study into the costs and emissions impacts of the addition of solar and wind power to a predominately fossil-fuelled electricity grid.  The study found that the impact of 33% wind and solar penetration on system operations is to increase cycling costs but also to displace annual fuel costs by approximately $7 billion. The study also found that up to 33% wind and solar energy penetration in the United States’ portion of the Western grid avoids 29%–34% carbon dioxide (CO2) emissions throughout the western grid.
