I fail to see how permitting, etc. has anything to do with battery capacity. The only thing that will matter is price per kWh of storage and if used batteries can be sourced, binned and serviced reliably.
The cost of the batteries is probably not a large component of the overall project cost which includes permitting, insurance, substation, inverters, labour, transportation of all of the above equipment. So to then cheap out and buy batteries that have half the life or half the density and probably greater risk of failure, Fire, higher insurance costs is not something I see people managing 50-150 million dollar projects sticking their neck
Out to do to maybe save 10%? But then have lower reliability, more maintenance, and a complete replacement
Of all the batteries coming in half the time as it would be with new ones.
