Of course it helps to provide consistent power to their customers and not be caught unawares like, apparently, the natural gas plants in California were by the demand from the heat wave.Not helpful with providing 24/7 power with solar.

They did not. None of them failed. They ran out of "fuel" when the sun went down, but when the sun came back up they resumed operation with no maintenance required. The same could not be said of the multiple natural gas plants that DID fail under the load.And solar panels failed

Because it tells them when they might need to provide other sources, of course. Todd, you're starting to look a little desperate. You're not going to get me to turn tail by endlessly repeating "the sun also sets".Of course it helps to provide consistent power to their customers
How is a few hours of intermittent power helping to provide consistent power?
Do you know what consistent even means? What about dispatchable generation?

I haven't the faintest idea what you intend by the term "dispatchable"Other sources? Because solar isn't reliable? Good to know.
Todd, you're starting to look a little desperate.
Why would unreliable solar make me desperate?
Why do we need dispatchable generation? Doesn't wind and solar qualify?

Do you, perhaps, mean PORTABLE? I have spec'ed the purchase of three, 150 kVA PORTABLE diesel generators and leased several more when I was working and no one ever called them "dispatachable".Clearly.

Why thank you Todd. I've never heard of them. Wind and solar can certainly adjust their output downward. They are controlled.Dispatchable generation refers to sources of electricity that can be programmed on demand at the request of power grid operators, according to market needs. Dispatchable generators may adjust their power output according to an order.[1] Non-dispatchable renewable energy sources such as wind power and solar photovoltaic (PV) power cannot be controlled by operators.[2] Other types of renewable energy that are dispatchable without separate energy storage are hydroelectric, biomass, geothermal and ocean thermal energy conversion.[3]

Why thank you Todd. I've never heard of them. Wind and solar can certainly adjust their output downward. They are controlled.
If it has been taken down, it can be returned to a higher power output. Just as a gas or steam turbine cannot produce more than 100% power, a PV panel cannot produce more energy than the incoming light will allow. They all have limits. So what do you do if your gas turbine can't make enough power to satisfy your need. You could bring some wind turbines or solar fields online. Free fuel. Much less maintenance. Just depends on your PoV.You can adjust turbine output down by changing the angle of the blade or by taking it offline.
Solar, probably by taking it offline. Tracking ones you could move them to a less efficient angle.
How do you take either of them up?
What if a weather forecast shows slower winds or more clouds over the next 3 days?
How do you make up for that reduced output?
You can't just put 10% less power through the wires, most modern equipment won't handle that.

Neither can a gas turbine or a coal furnace.If it has been taken down, it can be returned to a higher power output.
Can't be taken higher than full output, can it?
Weather forecasts will give you far more than one hour's warning. And there is no requirement to rely on "the wind field next door". You can go to the wind field in the next state or the solar field in the next county that happens to be sitting in full sunshine.If the field of solar panels is going to see a dip in an hour,
how do you ramp up the wind field next door?
Just pointing out that the core of your criticism here of wind and solar applies equally to every other means of generating power. They all have limits and none are guaranteed to always meet demand.So, what do you do if your gas turbine can't make enough power to satisfy your need.
Gas turbine? What is a gas turbine doing in our glorious "green" future?
