Zagreb Te-To CHP Power Plant Croatia is a 328 MW gas power station in Grad Zagreb, Croatia. It is operated by HEP-Proizvodnja doo [100%]. Based on its capacity (estimated), it can supply roughly 369k homes (estimated). It ranks #7 of 28 Croatia power plants by installed capacity. Commissioned in 1979, it is around 47 years old — long-established. Its annual emissions of 908,702 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 212k cars driven for a year. In context, gas supplies about 18.8% of Croatia's electricity; the national grid averages 158 gCO₂/kWh (76.3% low-carbon) (2025).

In context: how this plant compares
At 328 MW, Zagreb Te-To CHP Power Plant Croatia is well above the median gas plant in Croatia (89 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.

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 temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 45.8°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 13% above 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: 56/100 — 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
This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), 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.
