Texas Needs Equivalent of 30 Reactors to Meet Data Center Power Demand
-
“Baseload” nuclear has the inverse problem of renewables. It needs to sell all of its very expensive power near 24/7.
Excess nuclear production at night recharges batteries for daytime use, reducing the need for battery and solar rollout. Excess solar production during the day recharges batteries for nighttime use, reducing the need for baseload supply. Daytime use is higher than night time use, so this is pretty close to the ideal setup, no?
Use each non-polluting source for what it's best at. You don't need any one source to be the primary supplier of electricity, you want a diverse enough set that you get an optimal mix to keep costs and pollution low and reliability high. Mix in some wind and others for opportunistic, cheap generation.

Just that the lack of cheap energy built/connected is a function of all of the obstacles put in the way of those projects. They get done in Texas more than other places that "put out a better virtue vibe", but behind the scenes put up obstacles.

Yes, both can charge batteries. Solar charges then at 10x less cost, and combined solar+batteries provides the same total "baseload function" at 2x-4x less cost, and can be up and running in 1 year instead of 10, and expanded the year after that. It's even a myth that nuclear uses less land. You can use the land under solar, and you don't need exclusion zones around reactors and uranium mines
-
It's lower initial cost, sure, but what about longer term? Surely battery costs add up long term as they need to be expanded and replaced, making nuclear more attractive after 10-20 years.
I'm not an expert here though, I'm merely saying a lot of people would be fine with a higher initial investment if the long term benefits justify it.

No. Nuclear also has fairly high operations/staff costs, and fuel is highly variable and more expensive the more other nuclear plants there are. You mentioned the possibility of charging batteries (Hydrogen also possible) from nuclear, to handle peak day use/transmission, but batteries pair better with solar, and as a total package can serve same "baseload" purpose as nuclear but cheaper. There are no long term benefits to nuclear... economic ones ignoring weapons motivations.
-
Hydrogen also possible
Yeah, I just think of hydrogen as a battery, and it can totally be a closed loop system.
batteries... cheaper
Is that actually true though? As in, if we add up initial installation cost + running cost + replacement cost long term (say, 50 years), are batteries generally cheaper?
If so, then I'd agree. But my understanding is that nuclear gets really competitive the longer it runs.
-
Its interesting how you can only talk positively about Texas by comparing it to others.
Can you answer this question without comparing Texas to any other state or entity: How is charging hundreds of dollars per kWh during storms in the best interests of the "regular electricity consumers"?

LFP batteries are the cheapest and also last the longest. Race car EVs want the more energy dense NMC chemistry that was the original lithium formula. With 4 hour storage/discharge instead of smaller 1 or 2 hours, LFP batteries can last 10000 cycles which is 30 years on a daily charge/discharge cycle. A couple of years ago, this battery chemistry was $300/kwh and still cheaper than nuclear. They are now below $100/kwh, with some Chinese EVs having a free car at $300/kwh price for just the battery pack component. EVs permit a private investment to provide grid service that helps pay for EV, but at no rate payer passed down capital cost.
Batteries don't really have operating costs. Nuclear has a lot of maintenance costs especially when its time to push plants past 60 years. Diablo Canyon is spending $5B for 5 year extension. That could buy 5 times the solar power (at least more total power output over 5 years) for 30+ years instead.

I recognize that failing, but afaiu, it applied to a limited number of customers who "gambled on variable rates". The political leadership there also shit talks renewables, putting false blame on them for grid failures, but the actual operational environment still permits a lot of renewable expansion: The basis for calling their system the least corrupt.

Is that 5x including battery storage? And is that 5x including degradation over 30 years?
I'm down for whatever is the cheapest way to get us off of fossil fuels over the long term. My understanding is that generally means a mix of baseload supply (nuclear, geothermal, hydro), "bursty" reveals renewables (solar, wind), and storage.
-

It's 5x more without batteries. The degradation level of modern panels makes them last usefully much longer than 30 years, but it's reasonable to still just use 30 years excluding the free power past that point.

solar is cheapest, wind is complementary reducing battery needs. Hydro is less expensive than geothermal, and the latter is not as suited to giant power projects. Both provide the opportunity to be used as batteries pumping water uphill or heat down into the reservoir for "peaker power use" later in the day or seasonally. Solar and wind can power everything, but companies with expertise in other sectors can offer to help too. It's only nuclear that is pure corruption uselessness.
-
Do you genuinely think the folks who "gambled" really understood the implications?
I mean I'll grant you California is a shitshow but it's been a shitshow since republicans got on their knees for Enron in the 90s. How about Florida, which has been a red state for 80% of the last 30 years, low regulation, but instead of building new power they are keeping nukes going well past their service life?
-
So their renewable expansion is so good that it out ways the fact Texas never joined the east or west interconnect?
That is the biggest corruption, and it is the whole reason their grid is so unreliable. But iteruptions in sevice can be good for the people making money from the sales if these goods. It's like racketeering.
