pumped hydro has a lot of reliability when it is between 2 dams
vs
hydro generation which has variable reliability on inflow and outflow.
If hydro and battery are same price for 4 hours, then great, but that battery is either a daily cycle or emergency only cycle battery, but not both.
if hydro for 168 hours is same price as hydro for 4 hours, then its obviously better and can be used for both daily cycle and emergency only cycle.
a hydro dam with 168 hours capacity is far greater usefulness than a hydo dam with 4 hours capacity. just as
a hydro dam with 168 hours capacity is far greater usefulness than a battery with 4 hours capacity
diminishing returns, but its still 42x times longer capacity for the same money.
until the water all evaporates.
Don't understand "if hydro for 168 hours is same price as hydro for 4 hours, then its obviously better and can be used for both daily cycle and emergency only cycle."
