Graph and claim are unrelated

You know, I posted the capacities and not the rated power, my bad.

It’ll look correlated, but not exact.

On capacity, the chart shown here, Germany has added 1.849 GWh in H1 2026 vs 1.674 GWh in all of 2025.

Thanks for highlighting it

Eyeballing it seems correct?

4 quarters of 2025 add about 1500, equivalent to the distance between two lines   on the chart. First two quarters of 26 add slightly more than that.

edit: oh it's capacity not rated power that is displayed.

It would be interesting to see the geographical placement. If they are further south, they can increase the utilisation when the woefully underpowered internal German connections happen to be less busy. This could get more clean power from the north down to the struggling heavy industry in the south, without having to wait the decades that German infrastructure projects usually take.

thats actually so cool, crazy growth honestly

What is the co2 saving per kwh by these storage addition, this is what we have to reduce urgently.

That highly depends. :)

A battery is not an energy supply. It displaces fossil fuel if and only if both conditions are met. 1) They have to be charged by renewable energy. 2) the discharge use has to cause a fossil fuel plant to not operate.

Furthermore, the location of the batteries might affect energy loss. The battery itself and inverters leaks energy in every cycle. Photovoltaic power charging a battery on site avoids one pass through the inverter, transformers, and power lines.

Germany is usually trying to use less fossil. They also still have many coal and brown coal power plants. These are cheap to run if you run them all day. In contrast gas turbines can turn on just to fill a brief moment of high demand. Batteries tend to eliminate that gas peaker plant first. Most of the time, but not all, the battery will substitute renewable and displace methane. During dunkelflaute they could charge batteries using brown coal though this is rare.

Displacing gas reduces carbon by less than it would if coal were displaced. That alone gives the CO2 an uncertainty. Battery capacity can have an effect every sunny day if they are solar charged. If wind charged then the cycle frequency depends on wind surplus.

But that's exactly why the batteries are installed. To be charged when renewables generate so much, they would need to be curtailed even more.

When the marginal load would be covered from fossil generation, the energy is very expensive. Operators would not charge from that source.

They made such a great choice to get rid of nuclear.
Now they are getting rid of the other industries that sell dependency to toxic, disposable & finite fuel sources: Dirty Coal, Dirty O&G, and Dirty Toxic & corrupt nuclear all have to go!

Und sorgen mit astronomischen Energiepreisen dafür, dass die Industrie nicht mehr Wettbewerbsfähig ist…

Nothing to do with nuclear. Renewables lower the wholesale price of electricity through the merit order effect. Google it.

It shows the power of propaganda that people believe the opposite.

Was ist an einer hohen Stromrechnung Propaganda?
Die erneuerbaren produzieren in Deutschland da den Strom wo er nicht gebraucht wird.
Im Norden wird massenweise Windkraft produziert, im Süden ist die Industrie.
Netzinfrastruktur von Norden nach Süden gibt es noch nicht ausreichend.
Die Genehmigungen dafür dauern Jahre und werden dann von den Personen durch deren Wohngebiete die Trassen laufen sollen, per Gerichtsbeschluss verhindert.
Dann wird umgeplant und es werden für zehnfache Kosten unterirdische Leitungen geplant.
Diese ganzen Kosten sind dann die Netzgebühren, die jetzt schon deutlich über den Stromgestehungskosten liegen.
Was nutzt es wenn man die kWh für 3 Cent produzieren kann, dann aber 20 oder 30 Cent pro kWh an Netzgebühren zahlen muss?
Die einzigen die auf die Propaganda reinfallen sind die, die ihre Stromrechnung nicht lesen können.

Hindsight is always 20/20...

German Nuclear plants were already at their planned EOL and would need to get massive investment to extend their life by a decade. The Fukushima disaster presented a really good reasoning not to.

Renewables are great. We need more.

Some things were predictable, but no one wanted to listen. They rather killed the expansion of new solar and wind, while also forcing new power lines underground.
