T.B. DAM

Hydro power plant in Karnataka, India. Approximate location 15.2615, 76.3379.

HydroKarnatakaIndia

T.B. DAM is a 36 MW hydro power plant in Karnataka, India. Based on reported annual generation of 152 GWh, it can supply roughly 43k homes. It ranks #1252 of 2,229 India power plants by installed capacity. Commissioned in 1960, it is around 66 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 8.6% of India's electricity; the national grid averages 670 gCO₂/kWh (26.7% low-carbon) (2025).

In context: how this plant compares

At 36 MW, T.B. DAM is below the median hydro plant in India (80 MW). Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.

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

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a hot semi-arid steppe climate (Köppen BSh) — Northern Hemisphere, latitude 15.3°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.

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 benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion 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.
