Bet that Solar is Zero, unless Elon’s batteries are doing work taking the extra solar and storing it for later.
LG makes the batteries as well
But you make a good point. There isn't much of a point in installing a solar array without a BESS system to accompany it. But BESS systems to have their role to play in helping stabilize the grid.

for some reason i believe G2 chart over the other .

The chart lists capacity, not actual production. I wonder what the generation numbers actually average.

Because wind and solar both destroy the environment.
It works a maximum of eight hours a day. Not a power plant consumes power.

LG cells are fine. Their assembled batteries are hot garbage. Ask anyone unfortunate enough to end up with a resu10 on their house.

Are you old enough to remember the big freeze was accompanied by no wind. what did your chart say at 5 am regards solar contribution?
Quote:
Texas faced severe cold during Winter Storm Uri in February 2021, which resulted in more than 4 million people losing power for days. The blackouts were due to a significant loss of gas-fired power generation because not enough fuel could be delivered due to frozen wellheads and pipelines.
Those darned windmills….

Wind and solar farms are a blight on the landscape and humanity.

The bulk of the outages in Texas were from renewables. That is why we need NG and nuclear.

It LITERALLY says “Current Generation” as of minutes ago.
Yes, it will be different once the sun goes down. To claim that solar is not a significant contributor to the power production is just silly denial.
ETA: Per ChatGPT, when asked how much of Texas’ power generation in 2025 came from solar and wind:
quote:
In 2025, wind and solar made up a substantial share of Texas’s electricity generation, particularly on the ERCOT grid (which serves about 90 % of the state’s load):
?? Share of Wind and Solar in Texas Electricity (2025)
Combined solar + wind generation in 2025 on the ERCOT grid is reported at:
• ~36 % of electricity demand for the first nine months of 2025 (wind + solar) according to the U.S. Energy Information Administration (EIA). ?
• Multiple reports round that to about 37–40 % when looking at slightly broader data and different reporting periods within 2025. ?
?? Breakdown (Indicative, ERCOT)
• Wind accounted for the larger share of that renewables portion.
• Solar also grew quickly and in 2025 was estimated to be a significant contributor (~around ~10–14 % in some datasets). ?
(Exact percentages vary slightly by reporting period and methodology.)
?? What This Means
• Wind and solar together met over one-third of Texas’s electricity demand in 2025, showing strong growth compared with previous years. ?
• Renewable generation in Texas continues to push higher as new capacity comes online and solar output scales rapidly. ?

What should be on the second page is percentage impact of each of those to the outages.

This is where I have my doubts on this stat.
How ERCOT Determines Dispatch Priority
Economic Merit Order: Resources are generally dispatched based on their marginal cost, with the cheapest, most efficient, and available resources (often wind, solar, and nuclear) utilized first.
There is no way that Wind has a better marginal cost than natural gas or Nuclear when you consider consistency and reliable output. And clearly they are not taking into consideration the higher costs added when paired with necessary energy storage (e.g., lithium-ion batteries).
This is also on snapshot. As suggested, compare nighttime and seasonal where wind is low or rainy seasons when other source pick up the vast majority of sourcing.
I am not against natural sources of energy (because they are not renewable when you look at what it cost to create them). And they are not planet friendly when you look at how they destroy huge swaths of land while have no way to recycle or reuse efficiently.
Solar is great for lighting and poor at best for heating.

Every single person who posts on this board knows you are full of shite. If you had shame, you'd be embarrassed of yourself. You're just another liberal alert account. You're not "just one of the baws".

Sure there is.
“Marginal” just means “the next one”. Has nothing to do with startup, averages, or any other factor than the cost to produce one more.
If the wind is blowing, the only cost will be the actual cost of that next unit. If a rotation of the blades costs you something that you would not otherwise spend, that counts. Amortized fixed costs do not. I can’t think of a direct cost you incur for the blade turning one more rotation.
The natural gas will, in fact, cost whatever the price is of the gas.
I don’t know enough about the costs of nuclear to comment, but my guess is that it is indeed pretty nominal for production. However, I would be willing bet that the constraint here is actual capacity (and it’s already maxed, at least for its distribution channel).

Ive seen some huge solar farms in east texas. You want to discuss clean environment concening solar farms. Pfft

O&M expense does have a utilization (or availability is thats your preferred nomenclature) It's not alot but the more use rotating equipment has to more maintenance they need.

+ the other maintenance expenses.

Nuclear's problem is that the cost of capital is monstrous and buries the projects returns. That and the other O&M expenses are high as giraffe pussy too. It's just all around expensive.

All of what you said looks true, but those are not included in marginal cost analyses.
Example: O&M amortizations are built off assumptions of lifespans. One more rotation might bring a turnaround sooner (or might not), but the rotation itself does not incur a direct and immediate cost.
I’m splitting hairs here, but if the discussion is predicated on marginal costs, then a very specific definition is called for.

Fair point i missed that. I always go straight to total cost per Wh and bake in all the cost of capital, O&M expense, generation, etc. Thats what i always have to do to get the ratings agencies to shut up.
