WindSouthlandNew Zealand

White Hill is a 58 MW wind power plant in Southland, New Zealand. It is operated by Meridian Energy. Based on its capacity (estimated), it can supply roughly 49k homes (estimated). It ranks #38 of 50 New Zealand power plants by installed capacity. Commissioned in 2007, it is around 19 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 9.7% of New Zealand's electricity; the national grid averages 93 gCO₂/kWh (88.5% low-carbon) (2025).

In context: how this plant compares

At 58 MW, White Hill is around the median wind plant in New Zealand (60 MW). Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a temperate oceanic climate (Köppen Cfb) — Southern Hemisphere, latitude 45.7°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 26% above 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: 65/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
