RATNAGIRI GAS

Gas power plant in Maharashtra, India. Approximate location 17.5587, 73.167.

GasMaharashtraIndiaCCGT · HRSGCO₂ modelled

RATNAGIRI GAS is a 1,968 MW gas power station in Maharashtra, India. It is operated by Ratnagiri Gas and Power (NTPC / GAIL). Based on reported annual generation of 4,379 GWh, it can supply roughly 1.3 million homes. It ranks #141 of 2,229 India power plants by installed capacity. Commissioned in 2003, it is around 23 years old — relatively modern. Its modelled annual emissions are 1,744,800 t CO₂/yr (Climate TRACE), equivalent to about 407k 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).

In context: how this plant compares

At 1,968 MW, RATNAGIRI GAS is well above the median gas plant in India (238 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

~1,744,800 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

407kpassenger cars driven for a year
228khomes' yearly energy use
29 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from Climate TRACE.

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 monsoon climate (Köppen Am) — Northern Hemisphere, latitude 17.6°N — which shapes how much energy it can produce and how its output varies through the year.

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).

Site climate & environmental severity

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 an extreme marine/tropical environment (estimated ISO 9223 class CX — Extreme), with marine salt corrosion 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.
