Energy

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.

In 1957, Soviet authorities created a republic-level directorate for power generation, and in 1966 Turkmenistan entered the first phase of connecting its remote regions to the regional Central Asian electrical grid. By 1979 all rural areas of Turkmenistan were brought on line. Construction of the Mary thermal power plant began in 1969, and by 1987 the eighth and final generator block was completed, bringing the plant to its design capacity of 1.686 gigawatts. In 1998 Turkmenenergo commissioned its first gas-turbine power plant, using GE turbines.

As of 2010, Turkmenistan featured eight major power plants operating on natural gas, in Mary, Ashgabat, Balkanabat, Buzmeyin (suburb of Ashgabat), Dashoguz, Türkmenbaşy, Turkmenabat, and Seydi. As of 2013, Turkmenistan had 10 electrical power plants equipped with 32 turbines, including 14 steam-driven, 15 gas powered, and 3 hydroelectric. Power output in 2011 was 18.27 billion kWh, of which 2.5 billion kWh was exported. Major power generating installations include the Hindukush Hydroelectric Station, which has a rated capacity of 350 megawatts, and the Mary Thermoelectric Power Station, which has a rated capacity of 1,370 megawatts. In 2018, electrical power production totaled more than 21 billion kilowatt-hours.

Since 2013, additional power plants have been constructed in Mary and Ahal province, and Çärjew District of Lebap province. The Mary-3 combined cycle power plant, built by Çalık Holding with GE turbines, commissioned in 2018, produces 1.574 gigawatts of electrical power and is specifically intended to support expanded exports of electricity to Afghanistan and Pakistan. The Zerger power plant built by Sumitomo, Mitsubishi, Hitachi, and Rönesans Holding in Çärjew District has a design capacity of 432 megawatts from three 144-megawatt gas turbines and was commissioned in September 2021. It is also primarily intended for export of electricity. The Ahal power plant, with capacity of 650 megawatts, was constructed to power the city of Ashgabat and in particular the Olympic Village.

Turkmenistan is a net exporter of electrical power to Central Asian republics and southern neighbors. In 2019, total electrical energy generation in Turkmenistan reportedly totaled 22,521.6 million kilowatt-hours (22.52 terawatt-hours).
