Between 1955 and 1958, permanent post-war repairs were made to the dam and power station. The generators removed by the Soviets were replaced and the installed capacity of the power station upgraded to 630 MW. In 1983, China began constructing an additional power station just downstream of the dam on their side of the river with two 67.5 MW generators. The first was commissioned in 1987 and the second in 1988. The most recent renovation occurred between 2009 and 2011 in order to improve the function of the dam's spillways. The US$ 24.5 million renovation was funded by
