Concentrated solar power sails through the eclipse

Obviously, during a solar eclipse, the amount of electricity produced by a solar panel declines.  But concentrated solar power (CSP) stores the energy of the sun in tanks of molten salts, which means that a solar eclipse shouldn't impact power output at all.

And so it was. The chart below from Solar Reserve's twitter feed, shows sunlight compared with electricity generation, with the moment of the solar eclipse marked with a little crescent.  Note how stable the output is, even though there was what was prolly a cloud passing over at 9 am and the eclipse at 10.30.
