Battery factories can now produce roughly twice the storage cells the world installs each year, yet cell prices rose in 2026. Lithium, tariffs and sourcing rules, not manufacturing costs, now decide what a battery costs and where it can be sold.

Germany’s battery storage pipeline looks like a “tsunami” on paper, but grid connection requests say little about how many projects actually get built. The ones that do face a hard deadline: reach final investment decision this year to keep the grid ... more

What if a battery storage project could lock in its revenue before it's earned it? SSE and Statkraft have done just that with a battery revenue swap: SSE gave up the ups and downs of battery income for a fixed price, Statkraft took them on, and both ... more

Battery storage in Germany has a grid connection problem: far more projects want to connect than the grid can take, so Germany has scrapped first come, first served and moved to a maturity-based allocation scheme that rewards projects that are ready ... more

Talking Points

Recent interactions between the hosts and their guests.

Germany’s Battery Deadline Comes Before the Grid Rules Do - Kyon Energy
Q: What splits a regime that a developer like you can support and actually finance versus one that stops everything?
Braun says developers can manage market risk, but connection agreements become difficult to finance when grid operators can curtail projects without compensation and without a defined limit. A capped, quantifiable amount of uncompensated curtailment can be workable.
Germany’s Battery Deadline Comes Before the Grid Rules Do - Kyon Energy
Q: So what is the one thing that people get wrong about the German battery storage market right now?
Braun says the flood of grid connection requests is not a good measure of storage deployment. Many projects will not be built, and the industry itself has no incentive to install more merchant storage than can earn a return.
Inside Great Britain’s First Battery Revenue Swap - SSE & Statkraft
Q: Does that mean I now have to do exactly what the swap tells me to do? Do I have to physically dispatch and make sure that I'm trying to sort of replicate the floating position? Or do you have license to do whatever you see fit with the asset?
O'Duffy says owners and optimizers can operate in any market they choose. They should consider basis risk between their asset's actual revenue and the index used to settle the swap.
Inside Great Britain’s First Battery Revenue Swap - SSE & Statkraft
Q: What's the one thing that people get wrong when transacting a swap?
Cian O'Duffy says parties can overlook the operational work that makes a deal function, including credit support, booking, settlement and regulatory reporting.
Battery Storage in Germany: A Grid Operator’s View - 50Hertz
Q: Should we be trying to sort of tilt the balance a little bit so that storage pays for more of that wider upgrade work?
Kiewitt says batteries should not bear extra costs for wider network upgrades, because he expects them to lower system costs when integrated well. He sees data centres as a different case, where their operation and location matter to system costs.
