Nichols

Gas power plant in Texas, United States of America. Approximate location 35.2834, -101.7464.

GasTexasUnited States of AmericaSteamCO₂ measured

Nichols is a 476 MW gas power station in Texas, United States of America. It is operated by Southwestern Public Service Co. Based on reported annual generation of 1,164 GWh, it can supply roughly 333k homes. It ranks #1322 of 10,938 United States of America power plants by installed capacity. Commissioned in 1964, it is around 62 years old — an older, legacy facility. Its annual emissions of 740,727 t CO₂/yr (US EPA GHGRP) are equivalent to about 173k cars driven for a year. In context, gas supplies about 40.0% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

In context: how this plant compares

At 476 MW, Nichols is well above the median gas plant in United States of America (121 MW). Technically it is described as Steam. 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.

740,727 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

173kpassenger cars driven for a year
97khomes' yearly energy use
12 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per US EPA GHGRP (measured for US EPA/EU ETS, modelled for 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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 35.3°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 9% 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: 47/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~0% 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 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.
