Eclipse

Benchmarking the U.S. Electricity Grid against the Eclipse

California Solar Farm

On August 21st, the United States will experience a solar eclipse.

The eclipse will be visible across the continent, depending on cloud cover and other factors – like the lunar limb profile – and will last two minutes, give or take 1 to 3 seconds.

In California, where the sun shines almost all the time, utility-scale solar energy provides 8 gigawatts, or GW. Another 4 GW is private, and comprised of solar rooftops and arrays.
