This is the whole paradox! Because if there were more (from STEP), there would indeed be less variations in electricity prices, and therefore they would lose their profitability!
This is what I wrote two pages before:
"This is the confusion that often exists when we talk about electricity storage. The value is the service rendered, not just the quantity that can be stored, which will necessarily be limited, unless you have infinite pockets.
And the more the quantity increases, the more the value decreases, message to those who would say "yaka do storage"."
