HAIL1 — Saudi Arabia

HAIL1 is a 48.4 MW oil power plant in Mintaqat Ha'il, Saudi Arabia. It is operated by Saudi Electricity Company (SEC). Based on its capacity (estimated), it can supply roughly 36k homes (estimated). It ranks #148 of 156 Saudi Arabia power plants by installed capacity. Commissioned in 1983, it is around 43 years old — long-established. Its modelled annual emissions are 131,257 t CO₂/yr (Climate TRACE), equivalent to about 31k cars driven for a year. In context, oil supplies about 34.5% of Saudi Arabia's electricity; the national grid averages 692 gCO₂/kWh (2.2% low-carbon) (2024).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 926 MW for Hail-2 power plant, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

In context: how this plant compares

At 48.4 MW, HAIL1 is below the median oil plant in Saudi Arabia (364.6 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.

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a hot desert climate (Köppen BWh) — Northern Hemisphere, latitude 27.5°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.

Site climate & environmental severity

This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion 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.
