IU.S. battery storage capacity has been growing since 2021 and could increase by 89% by the end of 2024 if developers bring all of the energy storage systems they have planned on line by their intended commercial operation dates

Battery degradation isn’t as much of a concern in these cases. Batteries that are designed for grid backup use a more resilient chemistry which makes them heavier, but also last longer.
Consumer whole home backup batteries advertise the batteries having over 90% capacity after 10 years.
In a grid storage application, 90% of the original capacity is still fine, and as other commenters have pointed out, the batteries are recyclable.
