The efficiency of the process is 77%, which means it is profitable to operate when the electricity generated costs 30% more. The reservoir has the capacity to operate for 15 hours at full power, and the discharge rate is around 40 cubic meters per second. Normally it will operate from 6 to 10 hours, usually filling the reservoir at the end of the week. The cost of the Avče pumped-storage plant was €122 million.
