Oil power plant in Hawke's Bay, New Zealand. Approximate location -39.3829, 176.8875.
OilHawke's BayNew Zealand
Whirinaki is a 155 MW oil power station in Hawke's Bay, New Zealand. It is operated by Contact Energy. Based on its capacity (estimated), it can supply roughly 116,382 homes (estimated). It ranks #11 of 43 New Zealand power plants by installed capacity. Commissioned in 2011, it is around 15 years old — relatively modern. In context, oil supplies about 1.5% of New Zealand's electricity; the national grid averages 93 gCO₂/kWh (88.5% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from installed capacity at a typical 30% load factor × a typical oil emission factor (~750 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a temperate oceanic climate (Köppen Cfb) — Southern Hemisphere, latitude 39.4°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 36% 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: 35/100 — this site sits in the mid 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.
