The country has experienced total eclipses before, but the upcoming event on August 21 will be the first to affect utility-scale solar.
Power Standards Lab, a privately-held company that performs research projects with the U.S. Department of Energy and the National Labs, plans to measure the effects of the eclipse using precision grid instruments.
As the eclipse moves through the Western Interconnect and the Eastern Interconnect, grid operators will need to balance the output of thousands of grid-connecting generators against rapidly varying and localized grid-connected loads.
Power Standards said the eclipse will present a unique challenge to both the diversity and predictability of a significant amount of solar generation. Additionally, while grid operators know the location of their own solar arrays, they have less information about smaller rooftop solar arrays.
