Grid scale batteries are changing our electricity system. Excellent visual story on batteries in FT shows just how far this technology has evolved. Fasten your seatbelts, this is just the beginning. ig.ft.com/mega-batteries/

But that still doesn't solve the problem of peak load. After all, you can't force drivers or battery operators to discharge immediately.

The majority of negative (to battery usage) comments show interesting patterns: A) Did not look at the chart nor read the article B) use pre conceived framework to “fit” tidbit of data from the article into a different narrative C) plainly dismiss these data as a political/religious argument Well, let me help you out: there is no political force at work in Texas for the shift to solar plus batteries: simple economic of an unregulated market. As a matter of fact, Texas embracing of solar plus batteries is happening at a rate faster than California, specifically because Texas lets the market doing its things. There are no incentives nor regulatory preferences for any tech. Then look at China. Do you think China has a religious or green political agenda? Nope. Their goals are very straight forward: they want to increase FIVE times the energy consumption per capita in 10 years. They need a lot of energy and they will use whatever they can, including coal, a staggering 75 new coal production plants but… they know how to do math and they already know that the lifespan of these plant will not go beyond 15 years and they are already planning for their replacement with a more economic alternative…. Batteries! We can go on and on, looking at specific cases where an immediate transition does not make sense, I am with you, the world is a big place. I just wish you stop fighting the second principle. It rewards more efficient solutions when they become the most economical. Capex and sourcing was favorable to fossil fuels until this year, on global scale, now it is no longer. Pockets of favorable conditions still remain, but they are pockets, destined to shrink. There is no political nor religion nor conspiracy at play here. Just the hard numbers of economics at play in two markets that are immune to these sways, Texas and China. Failing to appreciate it is understandable, the article is about a really bad example of California where political pressure has intermingled with economical decisions for way too long and way too deep. Just dig a little more in the article would help. Looking at what the operators are doing is even better. Understanding the engineering behind electrical grids is almost optimal. Researching geopolitical motivations and strategic goals is perfect. Or simply observe nature and learn about the second principle.

“What grid operators and utilities value from batteries is flexibility,” says Mark Dyson, a managing director at the Colorado-based nonprofit RMI. “They can be a ‘swiss army knife’ and do whatever is needed on the grid, when and where that is required.” If flexibility is what you’re looking for @PoweredByEos Z3 battery is unrivaled in that regard

I have solar and two Tesla powerwall 3's. I understand this chart. But this is also why under gov newsom, CA, rates went from $0.15 to over $0.50/kwH. Batteries just cost more, and need replacement down the road. Reality...

Energy storage is the future ..

Now look what it has done to the cost of power.

Dropping price curves popping up everywhere.. Wrights law in full force…! Gilders maxim now the golden strategy .. waste what is suddenly abundant to deliver what has suddenly become scarce.

If you had nuclear you wouldn't need solar or batteries. Think about it. Clean energy 24/7. You can store uranium for years and years

Any info on how much domestic home batteries are flattening the curve? I personally think they have a big role to play in the future.

I don’t know why the government isn’t encouraging all homes and businesses to install solar and batteries with a 5 year interest free loan. This would significantly ease peak loads and soak up excess wind. And apart from admin and inflationary losses would not cost them anything

They would change the system even more if we put grid scale batteries on train rails.
Replying to @janrosenow
But, now, solar farms must be even larger to simultaneously handle both real-time panel supply and recharge for nighttime battery supply. Please, quote us THAT price tag.
Replying to @janrosenow
But ask the question in a power outage , how long will they keep the lights on , the answer is usually not long , yet they have cost us millions & many originally had diesel back up generators !

Spain is producing 53,80% of its energy demand with solar. We are waiting for batteries 🤗🔋🌞

Issue is is it the right tech / cost ? Uk gov millibrain quacks heat pumps, solar, wind turbines, smr. Musk talks future orbiting solar panels, power by RF to earth. Poss 24/7 solar (orbit or networking) Makes heat pumps, wind turbines, nuke power redundant overnight.

Question: How much subsidies had to flow to reach status quo regarding batteries + solar & wind? Ie. whats system lcoe of this combination? And how would this work in countries like Germany with sometimes several days without sun and wind?!
Replying to @janrosenow
It can do that - yes. But if you overlay demand on top of this you’ll see that solar productivity peaks at low demand during the day. Can’t dispose of the power. Can’t effectively cycle other inputs. Full-cycle cost is higher due to this disconnect.

Add a €€€-scale and consider that batteries need to be replaced after 15-20 years. Then think again.

COP30 agitprop. How about some honest talk about mining for those battery materials!
Replying to @janrosenow
Getting there. It's now ~5% of daily output.
In a different perspective when looking at energy (GWh) instead of power (MW) batteries🟢 5% of total of demand in Aug. fossil gas🔴 34% and solar🟡 29% (some of which went to batteries) From my Generation total dashboard intermittent.energy/d/ddj485…

Redox-Flow-Batterien entwickeln sich rasant! Doch ohne starke Netze und Sektorkopplung können wir ihr Potenzial nicht nutzen. Die FT-Daten zeigen: Die Technologie wartet auf bessere Rahmenbedingungen.
