VAR_CAP depends on any new capacity installed (VAR_NCAP), past investments (specified by either NCAP_PASTI or PRC_RESID), and the technical lifetime NCAP_TLIFE (which affects VAR_CAP via VAR_NCAP and NCAP_PASTI). In addition, investment lead times (NCAP_ILED) and early capacity retirements may affect it, but only if you have activated them.
For keeping the capacity of a process constant, you could e.g. specify a constant PRC_RESID, or a single NCAP_PASTI with a long lifetime (and disallow new investments). Or, you could use a constant bound on VAR_CAP (allowing new investments).
