Massive PPA for Los Angeles: PV + Battery Under 4 cents a kWh

Wed Sep 11, 2019 6:14 am

https://pv-magazine-usa.com/2019/09/10/ ... n-the-usa/

400 MW AC PV paired with 300 MW/1.2 GWh battery storage. This is the type of design that covers the 5pm - 9pm evening demand with PV

Excellent stuff. We’re in the beginning stages of great things with battery storage and prices get better every year.

Hopefully it works and doesn't turn into another Ivanpah or high speed rail project.

Indeed !

I presume that the bid makes future assumptions about battery prices since the project will go online in 2023. PV projects do the same and in general have found future prices to be even lower than projected. Since this project is a PPA, I did not see project cost. Too bad; I would have liked to estimate battery cost.

The other side of battery improvement is longevity. Jeff Dahn recently published a Li-x chemistry that lasts for 1 million miles in an EV or 20 years in a storage application.

Good news for California City, I suppose?

Guy figured building massive city in the middle of the Mojave desert would attract the masses.

Hmmm. No water, no jobs, not fun climate, too far away from whatever; sure that was going to work.

^^ Isn't that a little harsh ?
It is only a 3 hour commute to L.A. at East Coast speeds
One hour at CA speeds on an open highway
30 minutes in a nice train.

In fairness to the original developers, they *thought* they had an adequate water supply. And if in fact the city had grown as hoped, you can bet the political mass would have taken the water from elsewhere. Just like L.A

Frankly, the existence of Phoenix says that a city can pop up just about anywhere, hell be damned

I don’t know much about Phoenix, but apparently it required adequate water as with most nascent cities, in that case from the Salt and Gila Rivers, allowing it to start as an agricultural city.

If California City can buck that trend with a reboot with massive solar farms, they should buy the rights to rename as Solar City. Heck, maybe Elon could buy the city, build out solar PV everywhere, would license the name for free, have a SpaceX port next door, and Boring tunnels to L.A. and NorCal...

If I haven't misplaced a number anywhere, the first year's projected generation works out to an expected CF of 24.4% with just under 20% guaranteed; 25% being about the peak CF in the best desert sites. Naturally, CF decreases each subsequent year as the panels degrade. This is a fantastic price, IF it meets its claims.

Oh great... Los Angeles will spend millions... Billions? on a giant solar panel city. At what cost to the tax payer? Did they vote for it? Does LA really NEED 4 cent/ KW electricity? By building giant monstrosities?

Here is an example of the first signs of "sustainable cities", in which the government will design cities without consulting the citizens.

They should take care of the homeless problem first, and finish building the wall. I love these idealistic, out of touch with reality politicians.

I'm not saying that generating electricity from solar is wrong. In fact I believe that our future (distant} is solar. I think that it is laughable that they are willing to spend Billions on a New Green Deal pipe dream while our country cant even build a darn wall...
