Won't this be interesting (Solar Eclipse and GT power)

California’s sun will go dark Aug. 21. And when the moon crosses the sun, California’s solar power grid will slowly, quietly, stop working.
State energy officials are warning residents to click off all lights they don’t need and unplug all electrical appliances when 62 percent of the sun disappears over Los Angeles during a partial solar eclipse that is expected that day.
Nobody is warning of blackouts. But then again, nobody knows what will happen.
"When the sun goes away, so does the energy that powers our renewable solar panels. If millions of Californians turn off appliances and power strips to unplug from the grid during the eclipse, we can let our hard-working sun take a break,” said Michael Picker, president of the California Public Utilities Commission.
The California Public Utilities Commission has branded the upcoming eclipse as not just a solar eclipse but the “Great Solar Eclipse.”
It’s only a partial eclipse that will travel across California from about 9:02 a.m. until 11:54 a.m. Pacific time. But still, it will be significant because of the solar energy that the state’s energy grid will lose.
A California Public Utilities Commission statement said the sun was expected to be obscured from 76 percent in Northern California to 62 percent in Southern California, “and this reduction in solar radiation will directly affect the output of both large-scale photovoltaic (PV) electric power plants and rooftop solar.”
“Nearly 10,000 MWs of commercially operational grid-connected solar PV is currently operated by California's investor-owned utilities, and more will soon be completed,” the CPUC statement said. “Initial estimates show at the eclipse peak, commercial solar production for the investor-owned utilities will be reduced from an estimated 8,754 MWs to 3,143 MWs at the maximum partial eclipse and then return to 9,046 MWs.”
“The normal morning solar ramp will be interrupted with a down ramp beginning at 9:02 a.m. followed by a greatly accentuated up ramp beginning at 10:22 a.m. until noon,” the CPUC statement added.
California is not expected to experience another eclipse of this magnitude until 2045. But more importantly, an eclipse like this has never happened while California has depended so much on solar power.

Just covering the rear ends of politicians if "something" goes wrong.
I am not sure I understand or agree that these numbers are accurate (loads, generation, solar/RE generation), but there is a lot of information here. Will be interesting to click here on August 21st and see what happens:
http://www.caiso.com/Pages/TodaysOutlook.aspx
It appears that we have a 26 GW load and a peak of near 10GW of solar on a sunny day.
At least from the numbers, we have enough natural gas fired plants (>~35GW) to run normal loads even if everything else went "dark". But, has the fine print says: “Installed capacity” refers to the total amount of generation capacity, but does not reflect the total generation available for dispatch at any given time.
-Bill
It does show how there's a limit to how much solar can realistically make up of capacity without a viable storage mechanism, even in areas with good solar resource.

I wish I still had access to the metering/monitoring systems for the larger ground mount fields that we worked with when I was at Sun Edison. That would be interesting to watch!
Below me in the central valley it is close to $.20/kWh baseline and $.40 for the next tier. After that you are a high user and pay a fee for that. So if you use cooling, and they have to down there, you get to really pay some denaro!

The Solar Eclipse is Coming – Be an Energy-Saving Champion on August 21st!
To help support California and San Mateo County in our energy reduction efforts, please curb your electricity consumption during the solar eclipse on Monday, Aug. 21, 2017. If we all use less, California can avoid buying supplementary electricity generated by fossil fuels, which generate more GHG emissions, while the state’s solar energy production is affected by the eclipse. Please follow these tips to curb your electricity consumption between 9 a.m. and noon on Monday, August 21st, 2017:• Avoid printing, copying, and scanning when possible.
• Take advantage of natural daylight and turn off the lights.
• Do not run the dishwasher and washing machine/dryer between 9 a.m. & noon.
• Turn off unused computers and monitors.
• Take the stairs – use your body’s energy instead of electricity to power an elevator.
• Turn off the air conditioner. • Close the windows and blinds to shade your home and office to maintain a more comfortable temperature inside.
• Unplug items that are not in use. It takes energy to power the microwave, heat water, make coffee, etc.
• Limit the use of personal electronics (for example, fans, space heating, cell phone charging, clocks, hot water heaters, etc.).
• If you need to charge batteries or battery-operated equipment, do so before 9 a.m. or after noon.

What Damage Could Be Caused by a Massive Solar Storm?
An enormous solar storm could short out telecom satellites, radio communications, and power grids, leading to trillions of dollars in damages, experts say

On Wednesday, NASA released an image of a series of enormous sunspots snapped by at the Solar Dynamics Observatory, an orbiting telescope. The sunspots—the dark spots in the center of the image—are estimated to be larger in diameter than six Earths placed next to each other.
These sunspots pose no inherent danger—they’re merely temporary areas of intense magnetic activity that inhibit the sun’s normal convection currents—but, on occasion, the unstable area around a sunspot can trigger an unusually large solar flare (below), flinging streams of radiation outward from the sun. And a big enough solar flare can lead to an alteration in solar wind significant enough to set off a geomagnetic storm here on Earth, with the potential to short the circuitry on satellites and disrupt our telecommunications infrastructure worldwide.
To be clear, such a scenario seems unlikely to occur from this current set of sunspots—SpaceWeather.com indicates there is just a 15% chance of X-class flares at the moment, the minimum level necessary to knock out satellites and ground-based communications technologies. But we decided to take this opportunity to imagine just how far-reaching the effects of a massive solar flare would be in today’s ultra-connected world.
It so happens that at least once during recorded history, a solar event of this magnitude did occur: the solar storm of 1859. On September 1 and 2 of that year, the largest geomagnetic storm in recorded history occurred, causing aurorae (the northern and southern lights) to be visible around the world.

And it's not a matter of "if"............
And Dave, to even further amplify your comments, let's discuss where those transformers currently being made.

It is good that the people we elect are too busy taking care of important things like gender reassignment/dysphoria and reclaiming all the metal in those confederate statues.
If they had time, imagine the damage they could do, up there at a level with Carrington!
