Looks like it hit 554MW at 20:55, right after you took your screen shot.

Really have to wonder if V2G were available and in use for a majority of EVs in California, how much more of the peak use would be absorbed - the costliest power of the day for utility to purchase.

FPL demolishes 500-foot-tall stack and chute at its last coal plant in Florida
Florida Power & Light demolished the 500-foot-tall stack and chute of its last coal plant in the state Wednesday as the company has ended its use of coal in Florida.www.local10.com
Note that that's just FP&L.
Not all coal plants in Florida have retirement planned.
The Jacksonville utility has coal generation with no plans to close it.

Switching From Coal To Batteries At Power Plant In Maryland - CleanTechnica
Talen Energy is installing a 20 MW battery at the site of a retired coal-fired generating station. It's an experiment that could lead to a total of 1 GW of batteries at other locations.

The Natural-Gas Glut Has Evaporated, Driving Prices Higher
Demand for the electricity-generating fuel is high as power plants prepare for the kind of air-conditioning use that comes with a hot summer.

I guess get ready for higher energy prices as gas provides much of the electricity generation. Gas appliances will also cost more to operate. Good thing we have installed renewables with long term contracts stabilizing our energy prices.
If the current rate of installation of utilty-scale renewable generation kept up, it would decrease natural gas electricity share by about 2% per year, which would be an average demand reduction of 0.78% per year. However, there is still a whole load of coal and nuclear generation to be replaced.The Natural-Gas Glut Has Evaporated, Driving Prices Higher

It would be catastrophic. The world needs ~ 30% CAGR
In terms of total planned additions/retirements listed by the EIA, and using 2019 Capacity Factors to give 100% CF equivlant generation changes:
| Type | Net MW 100% CF equivalent (using 2019 Capacity Factors) |
| Old (coal, nuclear and others that are generally declining) | -32712.3 |
| Renewable and batteries | 20878.45 |
| Natural Gas | 11858.36 |
| Other | 24.25 |
Note that there's not that much net change planned right now, although some projects are faster to market than others, so there could be less visibility into those in the EIA data.
Based on the planned changes, you can see significant reduction in coal, with nuclear declining, but still overtaking coal.
Significant increases in wind and solar and offshore wind appears.
CCGT grows, but not as much as wind and solar. NG steam turbine declines and NG combustion turbine is essentially static.
Batteries also increase significantly and make an appearance, which is no doubt a contributor to the stasis of NG combustion turbine.
Note that this is based on 2019 capacity factors. Those are also likely to continue to shift with the changes in technologies.

Concrete flywheel storage system for residential PV
A French start-up has developed a concrete flywheel to store solar energy in an innovative way. Currently being tested in France, the storage solution will be initially offered in France's overseas territories and Africa.

A few Euros per KWh? Sign me up for 50.
That is the price of the concrete and maybe the fiberglass over-wrap. The "balance of system" is clearly much more. 3 tons of concrete give 10kWh of energy storage. The story also mentions a deployment for frequency regulation services, which makes a lot of sense. Flywheels are also used for short duration UPS applications that only have to bridge the time until generators start up.A few Euros per KWh? Sign me up for 50.
Good to know, anything to reduce the cost will be welcomed... Home batteries are still averaging about $650/KWh. Getting it down to $450/KWh would make my desired 50 KWh system under $25K... actually affordable.

Probably not a good idea anywhere there's even a 0.0001% chance of an Earthquake. You don't want to see what happens if you shake 3 tons of concrete spinning at 10k RPM.

Organic-based EV battery turns to ethanol for a boost in energy density
While on the face of it, the lithium-batteries that power electric vehicles play an important role in our ongoing shift to sustainable transport, they aren't without environmental problems of their own. Batteries that use organic, readily available materials in place of rare metals are seen as a…

Underground Sun Conversion tech uses sunlight to produce natural gas
In many countries, long, dark winters limit the amount of solar energy that can be generated for much of the year. That's where the Underground Sun Conversion system comes in, as it's intended to use sunlight to help produce natural gas deep underground.

Utah has a large salt cavern they were wanting to store hydrogen, if this would result in NG + water, it may be a two-for-one deal.

I don't think we want or need more methane since it is a potent climate warming gas.Underground Sun Conversion tech uses sunlight to produce natural gas

So how would you propose to use renewable energy to power everything 24/7/365.25?
