The Solar eclipse on August 21 will affect photovoltaic generators across the United States, the EIA said.

The US Energy Information Administration looks at the effects of the upcoming solar eclipse on utility-scale solar photovoltaic (PV) power plants at an energy brief published on its website on August 7.

“On August 21, a solar eclipse will obscure the sunlight needed to generate electricity at approximately 1,900 utility-scale solar photovoltaic (PV) power plants in the United States,” the EIA said.

“However, relatively little solar PV capacity lies in the path of totality—where the sun will be completely obscured by the moon—and the North American Electric Reliability Corporation (NERC) does not anticipate the eclipse will create reliability issues for the bulk power system,” the EIA explained, adding that uring the eclipse, electricity generators in the areas affected by the eclipse will have to increase output from other sources of electricity generation to supplement the decrease in solar power.
