NAMRUP GT

Gas power plant in Assam, India. Approximate location 27.1858, 95.376.

GasAssamIndiaCCGT · HRSG

NAMRUP GT is a 162 MW gas power station in Assam, India. It is operated by Assam Power Generation Corp Ltd [100%]. Based on reported annual generation of 299 GWh, it can supply roughly 85k homes. It ranks #746 of 2,229 India power plants by installed capacity. Commissioned in 1990, it is around 36 years old — long-established. 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 98 MW for Namrup power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

Capacity claim grade: C_REVIEW_MANUAL - recommended action: manual_review_only - confidence: unknown. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.

Data provenance

The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

In context: how this plant compares

At 162 MW, NAMRUP GT is below 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.

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 humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 27.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 93% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 16/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~5% 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

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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
