CKI Lamma power station is a 3,260 MW gas power station in Hong Kong, Hong Kong. It is operated by Hong Kong Electric Co Ltd [100%]. Based on its capacity (estimated), it can supply roughly 3.7 million homes (estimated). It ranks #3 of 4 Hong Kong power plants by installed capacity. Commissioned in 1991, it is around 35 years old — long-established.

Not available
Known, modelled and calculated values are kept separate. Missing fields are shown as unavailable.
Capacity provenance
The public capacity above is the current source-record value. A 2026 tracker candidate lists 1,995 MW for CKI Lamma power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).
Data provenance
Capacity and fuel are the upstream open-dataset record, not yet matched to a 2026 registry or GEM entry.
capacity: GEM GOGPT; fuel: GEM GOGPT
In context: how this plant compares
Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); Mitsubishi Heavy Industries: M701F. 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.

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 (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 22.2°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 92% 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: 16/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~5% 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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
