Australia’s leadership in the uptake of rooftop solar and the huge amounts of exports to the grid has already created one remarkable change in the shape of the grid, including the emergence of the “solar duck” curve

But new analysis points to the virtual elimination of solar exports in many homes, thanks to the unexpectedly high uptake of household batteries.

Stunning success of home battery boom will slash rooftop solar exports, and reshape the grid – again

Australian households are not just putting in more solar batteries, they are putting in bigger ones. And that has big implications for how the grid is managed.

1/ 🦆🐫 When the camel meets the duck: how storage patterns have changed in 🇩🇪

Cool new illustration on the #OpenEnergyTracker: average daily operations of pumped hydro storage in Germany since 2015. A little 🧵
#storage #pumpedhydro #duckcurve

Die #DuckCurve, also wann am Tag wie viel Strom nachgefragt bzw wie viel eingespeist wird, was mittags immer stärker auseinander läuft, hat auch die Team-Namen inspiriert 🙂

Preise gab’s für die #Steckersolar Teams leider nicht, aber wir treffen uns noch mal!

Ausgangslage:
📈mehr als 2 Mio #Steckersolar Geräte in 🇩🇪
🦆Strompreis tagsüber folgt der sog. #Duckcurve: 0 € um die Mittag, Spitze morgens und Abends: https://www.gridx.ai/blog/germanys-duck-curve-integrating-renewables-into-smart-grids
🔋Laden von #Speicher soll #netzdienlich erfolgen: "Peakshaving" and Valleyflattening. https://solar.htw-berlin.de/publikationen/mit-wenigen-klicks-prognosebasiert-laden/

Dann was wir uns von so einem System erhoffen:

🚭 CO2 soll reduziert werden
👐 OpenSource
💰 Low Cost
👵 nutzefreundlich und einfach

Wir sind gespannt was raus kommt!

gridX – Germany’s electricity duck curve

Jan 30, 2025 – California’s duck curve is now a canyon curve due to high solar production. The same is happening in Europe. Learn why demand-side flexibility is the key.

@GreenFire As you can guess, grid-scale energy storage is now highly profitable in German. Just look at this #duckcurve. But a problem is grid connection of utility-scale batteries - this is sometimes very lengthy and partly also overly expensive. We also have lots of PV-batteries in homes by now - but these are largely operated only for maximizing self-consumption benefits, and are not guided by wholesale prices whatsoever.

I concur that energy storage is the big challenge for electric power.

Fossil fuels have an incredible energy density; enough to justify the huge investments we’ve made in storing and transporting the awful stuff.

Poor electric energy storage is why:

- the #DuckCurve exists
- #BEV are heavy, expensive, range limited and slow to charge

We are addressing this challenge via

- new sources for rare earths
- Upgrading the electric grid
- new batteries
- novel storage mechanisms

@Tann @Prosybris

We are now seeing hard data on how batteries stabilize the renewable energy duck curve!

Excess energy during afternoon is stored in batteries; and released during evenings -- when heavy load occurs!

@Pampa A very blinkered view. Unless you're prepared to use nuclear energy this is the best way of dealing with the #duckcurve we have.

SpaceX's Starship could help this start-up beam clean energy from space. Here's how (video)

"Once Starship is fully reusable, that will drive down the cost."

Rooftop solar panels are flooding California’s grid. That’s a problem.

As electricity prices go negative, the Golden State is struggling to offload a glut of solar power.
