Jieh 1 is a 347.5 MW oil power station in Liban-Sud, Lebanon. It is operated by Electricity Of Lebanon [100%]. Based on its capacity (estimated), it can supply roughly 261k homes (estimated). It ranks #5 of 10 Lebanon power plants by installed capacity. Commissioned in 1971, it is around 55 years old — an older, legacy facility. In context, oil supplies about 56.2% of Lebanon's electricity; the national grid averages 390 gCO₂/kWh (43.8% low-carbon) (2024).

The public capacity above is the current source-record value. A 2026 tracker candidate lists 616 MW for Jieh power plant, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
The capacity and/or fuel fields on this page include a source-backed provenance label from GEM, an official registry, Wikidata, OSM, or a cross-source match.

At 347.5 MW, Jieh 1 is well above the median oil plant in Lebanon (70 MW). Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 33.6°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 71% 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: 23/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
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.
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 corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion 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.
The #2 largest oil power plant of 7 in Lebanon by capacity.
