The upcoming solar eclipse is expected to cause a significant reduction in energy supply to the state’s power grid due to the sudden and dramatic decline in solar generation caused by the lack of sunlight.
Scheduled for April 8, 2024, the total solar eclipse presents an opportunity for tens of millions of skywatchers to witness the celestial event, marking the last chance to do so from the U.S. until 2045, according to scientists.
ERCOT, the Electric Reliability Council of Texas, has stated that they are making preparations for this rare occurrence.
Although there will be a decrease in solar power production during the eclipse’s darkness, ERCOT has expressed confidence that there will be no grid reliability issues.
The eclipse is projected to pass over the ERCOT region between approximately 12:10 p.m. and 3:10 p.m. CT.
Forecasts released by ERCOT on April 7 indicate that solar generation on the day of the eclipse could plummet from 99.2% around noon to about 7.6% at approximately 1:40 p.m.
ERCOT has been actively developing forecasting models to anticipate the reduced solar power production and will continue to monitor conditions while keeping the public informed.
To prepare for the eclipse, ERCOT has devised an 11-day plan to ready its marketplace of power suppliers. They plan to issue notices to their marketplace of suppliers leading up to the eclipse and will also monitor for weather events that could impact demand on the state power grid.
Regarding the timing of the 2024 eclipse, NASA reports that the eclipse’s path will traverse Mexico before entering the United States in Texas and proceeding through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine. Small portions of Tennessee and Michigan will also experience the total solar eclipse.
Several cities in Texas, including Dallas, most of Fort Worth, Waco, Temple, most of Austin, and parts of San Antonio, will be within the path of totality. However, Denton will be situated outside the path of totality.
In Dallas, the eclipse will commence with the moon covering the sun around 12:23 p.m., followed by totality beginning around 1:40 p.m. and lasting just under 4 minutes. The moon will then move away from the sun, with the spectacle concluding around 3:02 p.m. The exact timing may vary based on the location within the metroplex.
