Mary power station is a 3,259 MW gas power station in Mary, Turkmenistan. It is operated by Turkmenenergo [100%]. Based on its capacity (estimated), it can supply roughly 3.7 million homes (estimated). It ranks #1 of 15 Turkmenistan power plants by installed capacity. Commissioned in 1973, it is around 53 years old — an older, legacy facility. In context, gas supplies about 100.0% of Turkmenistan's electricity; the national grid averages 1,306 gCO₂/kWh (0.0% low-carbon) (2024).

At 3,259 MW, Mary power station is well above the median gas plant in Turkmenistan (254 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); GE Power: F.03, GE Power: F.03. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 37.6°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
The #1 largest gas power plant of 13 in Turkmenistan by capacity.
