Max age retirement of batteries #184
-
|
Hi there- I'm wondering why batteries' maximum age is constrained to 15 years, whereas the capital recovery period listed in the most recent ATBs is 20/30 years. maxage referenced: https://github.com/NREL/ReEDS-2.0/blob/e65ed5ed4ffff973071839481309f77d12d802cd/inputs/plant_characteristics/maxage.csv Am I interpreting the maxage usage in the model correctly? |

The capital recovery period in the ATB is only used to calculated the LCOE values. There are no storage LCOE values for storage in the ATB, so that 20/30 capital recovery lifetime is not used. The ATB specifies that batteries have a 15-year lifetime (https://atb.nrel.gov/electricity/2024/utility-scale_battery_storage), which is consistent with what we are modeling in ReEDS. Lifetime values from literature tend to be in the 15-20 year range:
