I think you may wish to rephrase this, when you say:
a)production/maintenance is subtracted from generation (which implies generation comes first).
b) Retrofits are withdrawn ....AFTER production/maintenance and BEFORE the generation.

In any event, are you trying to say (in order of sequence):

1) new storage limits are increased (ie new storage facilities constructed)
2) retrofits are paid out of storage
3) the net of production/maintenance and production is added or subtracted to storage.

Just a bit confused...
