"Eclipse Preparedness: Grid Operators and Utilities Brace for Impact on Solar Power Output"

A total eclipse on Monday is expected to cause significant losses in solar generation across the United States, with estimates of up to 39.9 GWh of lost production. Grid operators, including ERCOT, PJM, and the New York ISO, are preparing for the event by working with solar forecast vendors, utilizing gas infrastructure, and employing flexible loads and batteries. California, ERCOT, PJM, New York, and Midcontinent ISO are all making preparations for the eclipse, with each region expecting varying impacts on solar energy production based on the path of the eclipse and weather conditions.
