Gas power plant in Oklahoma, United States of America. Approximate location 35.4397, -97.625.

GasOklahomaUnited States of AmericaCCGT · HRSGCO₂ measured

Frontier is a 131 MW gas power station in Oklahoma, United States of America. It is operated by Oklahoma Gas & Electric Co. Based on reported annual generation of 236 GWh, it can supply roughly 68k homes. It ranks #2436 of 10,884 United States of America power plants by installed capacity. Commissioned in 1989, it is around 37 years old — long-established. Its annual emissions of 283,668 t CO₂/yr (US EPA GHGRP) are equivalent to about 66k 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 131 MW, Frontier is around the median gas plant in United States of America (121.2 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.

283,668 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

5.2kmillion cubic feet of natural gas burned
59khomes' electricity use for a year
284kacres of US forest absorbing CO₂ for a year
0.04%of the CO₂ from all United States of America power plants with an emissions figure in PowerAtlas

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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 35.4°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 27% 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: 40/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~1% 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 a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
