Vanadzor (Anaklia) power station is a 540 MW gas power station in Lori, Armenia. It is operated by Anaklia IEP Holdings Ltd; Grange Power Ltd. Based on its capacity (estimated), it can supply roughly 608k homes (estimated). It ranks #5 of 11 Armenia power plants by installed capacity. In context, gas supplies about 34.1% of Armenia's electricity; the national grid averages 212 gCO₂/kWh (65.9% low-carbon) (2025).

At 540 MW, Vanadzor (Anaklia) power station is around the median gas plant in Armenia (550 MW). 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 warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 40.8°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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling 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 #4 largest gas power plant of 6 in Armenia by capacity.
Armenia has 6 gas power plants in this dataset, together about 3,978 MW of capacity.
