Kilowatts, kilovars, and system investments

WHAT portion of the total system investment can one equitably allocate to the system kilovar requirements? Or, looking at it in a little different way, what portion of the system kilowatt capacity is used by kilovars ? The answer to these questions obviously depends upon the method of supplying the kilovars. It is indicated in this analysis that supplying the kilovar requirements of a system in general may be divorced from supplying the kilowatt requirements and that the two factors may be dealt with as independent commodities. This approach shows that maximum usage of system capacity is made in producing kilowatts.
