SOLAPUR STPP is a 1,320 MW coal power station in Himachal Pradesh, India. Based on reported annual generation of 1,604 GWh, it can supply roughly 458k homes. It ranks #213 of 2,229 India power plants by installed capacity. Commissioned in 2018, it is around 8 years old — recently built. In context, coal supplies about 70.8% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

At 1,320 MW, SOLAPUR STPP is well above the median coal plant in India (1,000 MW). Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a subtropical highland climate (Köppen Cwb) — Northern Hemisphere, latitude 31.8°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 42% 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: 33/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
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.
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 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.
