Lihir is a 30 MW geothermal power plant in East New Britain, Papua New Guinea. It is operated by Lihir Gold Ltd.. Based on its capacity (estimated), it can supply roughly 56,314 homes (estimated). It ranks #6 of 15 Papua New Guinea power plants by installed capacity. Commissioned in 2005, it is around 21 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, geothermal supplies about 2.1% of Papua New Guinea's electricity; the national grid averages 514 gCO₂/kWh (23.7% low-carbon) (2024).

This geothermal plant taps underground heat to raise steam that drives a turbine. It sits in a tropical rainforest climate (Köppen Af) — Southern Hemisphere, latitude 3.1°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 100% 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: 13/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
