The power station was commenced in 1927, running two 5 megawatts (6,700 hp) turbines. In 1938, an additional two 5 MW turbines were added at the dam wall. In 1972, floods damaged the original two turbines, which were decommissioned. In 2017, the remaining two turbines were each upgraded to 6 megawatts (8,000 hp), and an additional turbine of 16 megawatts (21,000 hp) was added.[1][2]
