These days 1 kWh of LFP battery is 70-150 EUR depending on the brand, so far lower than referenced. And LFP cell lifetime is probably 20 to 30 years.
In a system it means that 1 kW of solar PV panels is about the same price as 1 kWh of battery, and similar lifetime.
Storage is booming in my very much coal-powered country with residential storage going from 115MWh to 670MWh over the course of 2024.
As it stands it's enough to power the country for about two minutes, but that's two minutes gained in a year.
In the commercial space there's a total of 4.3GW of peak output commissioned to be deployed before 2030. That will greatly help in shaving the afternoon increase in electricity usage.
