HPCL Vizag Refinery power station is a 178.4 MW gas power station in Andhra Pradesh, India. It is operated by Hindustan Petroleum Corporation Ltd. Based on its capacity (estimated), it can supply roughly 201k homes (estimated). It ranks #737 of 2,225 India power plants by installed capacity. Its modelled annual emissions are 176,760 t CO₂/yr (Climate TRACE), equivalent to about 41k 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 60 MW for HPCL Vizag Refinery power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
Data provenance
Capacity and fuel are the upstream open-dataset record, not yet matched to a 2026 registry or GEM entry.

In context: how this plant compares
At 178.4 MW, HPCL Vizag Refinery power station is below 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 Aw) — Northern Hemisphere, latitude 17.7°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 ~9% 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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
