California Solar Generation Record!

Tue Feb 25, 2014 12:56 am

I usually check the California ISO Today's Outlook page to see how we are progressing on our way to getting to 33% renewables by 2020.

Happily surprised today to see that we've hit 3.8 GW today in combined solar PV and solar thermal production - about 15% of demand.

Something else interesting - yesterday's net load (total demand - renewables) was lower between 10am-3pm than during the early morning minimum thanks to solar production around 4-5am. Check the 2nd page of this PDF: http://content.caiso.com/green/renewrpt ... sWatch.pdf" onclick="window.open(this.href);return false;

The current renewables generation plot is below:

Interesting! Thanks!

It looks like Ivanpah 1 and 3 may be producing close to their maximums (while Ivanpah 2 remains curtailed). I guess those two plants contributed about 260MW yesterday. Is that correct?

Do you have any links which provide the growth rates of solar PV and solar thermal electricity production? Also, do they collect private PV production information in real time?

Really hard to say, I haven't found any good sources of individual power plant production and the curtailed/non-operational generator page isn't necessarily accurate, either.

The CAISO page only shows utility scale plants. All net-metered PV generation only shows up as a reduction in demand.

The California Solar Statistics page has a lot of data, but I don't know how accurate is now given that CSI rebates have just about run out and aren't available in many areas.

Cool! Thanks!

So it appears that net-metered PV installations may contribute about an additional 50% to the 3.8 GW listed in the title (assuming most are well-sited and still operational).

Yes. Part of the requirement to qualify for the CSI rebate is that a 10-year warranty must be provided on the system as a whole, so unless the company went out of business and then the system broke down, the majority should still be functional.

Can you say 4.1GW?

Look at the graph in the first post!

Almost got to 4.8 GW today, so in 3 months California has brought online 1 GW of solar.

Not bad!

Of course, it's getting close to summer now, so 4.8 GW is still about 15% of total demand at the time (31 GW).

caiso graph looks a bit jacked up today.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.
LEAF traded at 45,400 miles for a RAV4-EV
RAV4 traded in for I-Pace Dec 2018

Yeah, it does that on occasion. Seems to get fixed eventually.

So I noticed that yesterday the 21st had Thermal (non-imported anyway) production drop to only 1.3 GW at 12PM out of a total demand of 16.8 GW. If San Onofre were still running with 2 GW of production, California could have shut down all local thermal generation for a couple hours.

Does that mean that it could actually be cleanest to charge your car during the day now with all the solar that's on the grid? I am very curious as to what the generation makeup of imports is at this point - is it gas? Coal? Hydro?
