Power Grid 2023

[TCHB]

Been a sleepy year with low low capacity factors. Prices have been negative lately.
Last year we had about two weeks of extreme demand. This year with all the hydro power at full throttle should be a non eventful year. http://www.caiso.com/todaysoutlook/pages/supply.html

Do you think hydro will consistently carry us through summer?

Meaning will it help alleviate the super high demand days?

Hydro is only about 24% of all generation In California. California will add about 9,000 MWs of new generation late this summer. With the dams full of water hydro will help. Look at the link I posted it is real time demand and supply. So far through May a lot of generation down off line not needed.
When the grid gets into Alerts it could be transmission outages or large power plants tripped off line during the high demand days.

Grid sleepy with generation of line waiting for the 16 days of summer. Prices are low low for the exposed generators.

What’s the logic behind importing power today? Cheaper to buy it then generate?

What’s the logic behind importing power today? Cheaper to buy it then generate?

1 Yes cheaper to buy MWs
2 Contracts with generators that supply MWs.

What’s August and September going to look like

 

[hallett21]

Looking at our supply right now it’s impressive what solar can produce when everything is going well. And I don’t mean that as knock on solar.

Yeah heard about that last week, over 80,000mw on 4 different occasions. I think CA highest demand was just over 52,000mw.

Interesting thing is solar is less expensive than a natural gas plant. I never thought I would see that so quickly.

and the interesting part about that whole thing is SCE is currently 3 full months behind on approving NEM 2.0 PTO requests.

Wondering what its all going to look like after all the 2.0's are fully processed.

 

[SoCalDave]

California's peak electricity demand of 52,061 megawatts occurred on September 6, 2022, during one of the longest and hottest September heatwaves on record, which encompassed multiple Western states.

That does not include all generation like DWP

 

[SoCalDave]

Sorry, talking about total demand not capacity.

Why are we still shutting down at night?????? 4th of July weekend we shut down for a whole day.
Scheduled to shut down in the morning.

[Not So Fast]

Became a solar power customer last summer, admittedly didnt do much homework about it but now im learning. Now that we've had it for about a year and accumulated some reserve power I guess, our power bill from Unisorce. for the last 2 months has been ZERO $$, so hopefully I did the rifght thing having it installed.
we have 30 panels for our little house, cost to the provider is $120@mo and $5 to Unisource for whatever. Unisource bill during same time frame was right at $300@mo , For what its worth

Demand is always lower at night. What kind of contract do you have?

Looks like it’s time to fire up the Coal burning plant . Europe has

modern day coal shit is no joke.

between how the inject the coal dust to fire it, to the scrubbers they run, its honestly almost zero emissions.

I'm not against coal, but if we were smart, we should be setting up a many smaller pebble bed nukes plants like China is currently doing. They MUCH smaller MW compared to the large plants like Diablo Canyon or San O, but are also much much more modern tech and 100x safer.

I am not sure, we are with APS during the summer. Our shut downs are at midnight to 3am and start up between 8 and 10am. We have done a total shut down then get a call a hour later to start back up.

Today with all the IPP contracts out there dispatch is all over the place.

Nat Gas just crossed over renewable production

I can remember we had 10 MWs of solar on the grid from SCE. This solar number does not include roof top solar which is approximately 1100MWs of residential climbing every day. Wind comes on at night.

 

[TCHB]

It is also interesting that SONGs and Mohave generating stations shut down many tears ago and the grid did not blink (3,500 MWs) We had a huge reserve margin.

Looking at these trends it sure seems like we’re gonna be on the rev limiter in August-September. Kids going back to school will definitely add to the load.

APS called it in this weekend and it expires tonight

 

[TCHB]

There is Alerts that are in place for California that help with high demand times. Get a break on your electric bill so the can shut down pools and air conditioners for a couple hours. Lots of different programs.

Ok Arizona must in the Alert Phase. California is not.

 

[shintoooo]

Not sure why they send kids back to school so early in August. I remember we always went back to school after labor day when we were kids.

I know they exist but you’ve got to be out of your mind to have them IMO lol.

I agree there’s a time and place for the systems but demanding more electrical loads (city and state officials) while asking for shut downs isn’t realistic.

And I’m not trying to make a debate as I appreciate the day to day monitoring and your and other utility workers insight. But it sure seems like we could hit a scenario where neighborhoods and cities blow a bunch of transformers and cause 1-2+ week outages.

I know a lot of utilities are still back ordered on transformers, even today.

Ya wtf lol.

I was told that it’s to put highschool kids on a similar system as the collegiate semester system.

But then if you go to college on the quarter system I believe you start middle of September? So that doesn’t really make any sense

 

[TCHB]

Demand much lower today

Was told it is to put standardized testing at the half in December before winter break instead of after winter break.

 

[hallett21]

Looks like renewables and Nat Gas are producing the same right now

 

[TCHB]

Roof top solar is about 1200 MWs not in the ISO window.

[SoCalDave]

Just recieved notification from SCE to curtail or power to our agreed amount of 50kw. We are on the BIP rate and it's required we curtail when advised.
Pros of BIP: we pay average on .123kw
Cons of it: Being plastics injection molding manufacturer it take hours to get the plant back up and running once the notification is lifted.
Surprised they call for it this late in the evening...

They start Aug 1 here, but they get more time off during the year. I think it has to do with farming here. They get time off in the fall to get the land ready for winter and in the spring for planting.

Not sure why they do it there, maybe to get more time off during the year too.

Are you able to just put the machines in an “idle” of sorts or is it a full shutdown?

 

[SoCalDave]

We have to get below our agreed contract of 50kw or we get penalized big time so it's pretty much a full shutdown. On average we run about 1,200kw 24/5.
Our last months bill was $85,339.
