MarketWatch – The total solar eclipse on Aug. 21, the first to arch the U.S. coast-to-coast in 99 years, will be a test of how well the country’s grid will handle an unprecedented swing in solar-power production.
Operators will have to balance a speedy loss of large loads of solar energy as well as the whiplash of that energy coming back to the grid as the eclipse runs its course.
Don’t reach for a flashlight just yet.
The eclipse will obscure the sunlight needed to generate electricity at some 1,900 utility-scale solar-power plants in the country, the Energy Information Administration said this week.
Relatively little solar-power capacity lies directly on the path of totality, or where the sun will be completely obscured by the moon, and no reliability issues are expected in the U.S., the EIA said.
