“According to the U.S. Energy Information Agency, only about 17 utility-scale solars are located on the path of the total eclipse, known as totality.
Most of those are in eastern Oregon. Hundreds more in North Carolina and Georgia will be at least 90 percent obscured, totaling about 4,000 megawatts of capacity. Another 2,200 to 4,000 megawatts are in areas that will be 80 and 70 percent obscured. (A megawatt is enough electricity to power about 1,000 homes).”
North Carolina-based Duke Energy, the largest utility in the Carolinas, is expecting solar production to plummet from 2,500 megawatts to about 200 megawatts.
“What we’ve been doing is running various scenarios of what the weather conditions could be that day,” said spokesman Randy Wheeless in an interview. “In the most extreme example would be a very sunny day with low humidity where we are probably getting 2,500 megawatts of solar during that time of the day.”
