A total solar eclipse can be viewed in the United States at the end of August, for the first time in almost 40 years.

For those plants in the eclipse's direct path-from OR east to South Carolina-solar-powered generators will find their power source blocked by the moon for up to three minutes, though they will likely be affected to a lesser extent over the entire three hours surrounding the event.

Down here in L.A., we'll only see 70-percent blockage of the sun's surface, but before you hop a plane to Carbondale, Illinois - where the sun will be completely blocked for the longest duration and where you can bet junkola motels are gouging the shit out of visiting eclipse gazers - there are a handful of events where you can marvel at what's still a pretty cool event.

"Such warnings are outdated and do not apply to eclipse viewers compliant with the ISO 12312-2 worldwide safety standard, which was adopted in 2015". The generators will also be affected to a lesser extent throughout the entire eclipse, expected to last up to three hours.

IN isn't in the path of totality, but southern parts of the state will have near-totality: 99 percent in Evansville, 96 percent in Jeffersonville, 95 percent in Bloomington and about 90 percent in Indianapolis.

The last time a total solar eclipse swept the whole width of the US was in 1918. Solar installations have grown ninefold since 2012 and renewable sources are forecast to supply just as much of America's electricity demand as gas by 2040, according to Bloomberg New Energy Finance. They not only prevent blackouts and brownouts but also instability in the power grid.

Time: Depending on where you watch, about 12 p.m. until about 3 p.m. EDT.

If you want to see a TOTAL solar eclipse, you will have to travel to Cape Giradeau, MO (~2 hours north of Memphis), Paducah, KY (~3 hours north of Memphis) or Nashville, TN (~3 hours east of Memphis).

But hundreds of plants totaling about 4 GW capacity will be at least 90% obscured, EIA said.

The solar eclipse will take place August 21, reported Pamela Hagy.

Based on a Bloomberg calculation of grid forecasts, more than 9,000 megawatts of solar power may go down.

For the path of direct effect, however, 17 utility-scale PV generators will be hit. Newell will be located in the 95%+ eclipse range with the peak occurring at 11:49 a.m., and ending at 1:13 p.m. The next US coast-to-coast eclipse is not until August 12, 2045.
