Imanta power station is a 48 MW gas power plant in Riga, Latvia. It is operated by Rigas Siltums AS [100%]. Based on its capacity (estimated), it can supply roughly 54k homes (estimated). It ranks #7 of 7 Latvia power plants by installed capacity. Commissioned in 2006, it is around 20 years old — relatively modern. Its annual emissions of 45,888 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 11k cars driven for a year. In context, gas supplies about 26.2% of Latvia's electricity; the national grid averages 139 gCO₂/kWh (73.0% low-carbon) (2025).

In context: how this plant compares
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.
45,888 t CO₂/yr — in everyday terms
This facility's annual emissions are roughly equivalent to:
Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per EU ETS verified (EUTL 2023) (measured for US EPA/EU ETS, modelled for Climate TRACE).

Climate zone & how it works
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 57.0°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
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.
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.
