Sugen Combined Cycle power plant is a 1,532 MW gas power station in Gujarat, India. It is operated by Torrent Power Ltd. Based on its capacity (estimated), it can supply roughly 1.7 million homes (estimated). It ranks #178 of 2,225 India power plants by installed capacity. Commissioned in 2009, it is around 17 years old — relatively modern. Its modelled annual emissions are 1,576,500 t CO₂/yr (Climate TRACE), equivalent to about 367k cars driven for a year. In context, gas supplies about 2.3% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

Capacity provenance
The public capacity above is the current source-record value. A 2026 tracker candidate lists 1,149 MW for Sugen Combined Cycle power plant, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

In context: how this plant compares
At 1,532 MW, Sugen Combined Cycle power plant is well above the median gas plant in India (234.3 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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.

Local climate & thermal context
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a tropical savanna climate (Köppen As) — Northern Hemisphere, latitude 21.3°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
This site has effectively no heating season (tropical/equatorial climate), so winter heat loss is not the driver here. The thermal concern shifts to year-round process heat and humidity/heat-driven corrosion of hot equipment.
A gas turbine here also runs ~8% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
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.
