The station operates at 0.8 lagging power factor, and the power factor is required to be maintained at 0.98 lagging power factor. The monthly electricity cost is 2·50 AUD per kVA. To improve the power factor, 350 kVA compensators are installed (with a negligible power loss). How could you retain a minimum level of saving while maintaining a superior power quality for your upgraded station due to the use of a synchronous compensator?
