The Thisavros Dam is a rock-fill dam on the Nestos River in the regional unit of Drama in the northeastern portion of Greece. it is north of Nikiforos and northeast of the town of Drama. The 172m (564feet) high dam is the tallest in Greece.[3] [4] It was constructed between 1986 and 1996. The purpose of the dam is irrigation and hydroelectric power production. Its reservoirs helps irrigate 80937ha and its power station has an installed capacity of . The power station is a pumped-storage type which allows it to not only generate power but the turbines can reverse and pump water back into the reservoir. Power generation occurs during periods of high demand and pumping during those of low demand such as at night.[5] [6]
