Utilizing generators` reactive capability to the fullest became critically important in the last ten years. Voltage stability studies reflect actual system conditions only as long as utilities assess their generators` actual reactive capability. Just as important, the system dispatchers and plant operators should be aware of the system`s actual reactive capability and have a good understanding of the impact that power plants` var production has on system voltage. This paper describes the Public Service Company of Colorado`s experience in maximizing its generating units` overexcited reactive capability. As a result of PSC`s effort, an additional 500 Mvars of previously unused reactive power were released to the power system. Furthermore, this paper presents PSC`s experience in educating the system dispatchers, plant operators and engineering personnel on the subjects of voltage collapse phenomenon and var scheduling in a power system.
