Turkmenistan's first electrical power plant was built in 1909 and went into full operation in 1913. As of 2019 it was still in operation.  The original triple-turbine Hindukush hydroelectric plant, built by the Austro-Hungarian company Ganz Works on the Murghab River, was designed to produce 1.2 megawatts at 16.5 kilovolts.  Until 1957, however, most electrical power in Turkmenistan was produced locally by small Diesel generators and Diesel-electric locomotives.
