Germany's power grid could technically support around 150 GW of additional solar photovoltaic capacity through smart battery storage at rural substations, surpassing the country's current installed solar capacity of roughly 130 GW. This approach leverages battery storage to better utilise transformer capacity by absorbing solar production peaks and releasing energy later.

◆ ◆ The Wire takeaway
Smart batteries at substations lift the cap on solar capacity your project can connect locally. You can target sites where existing transformers are underused and push more solar onto the grid without expensive upgrades.
