Mercury NZ is a New Zealand electricity company that generates and supplies 100% renewable power from hydro, geothermal and wind. It has five geothermal stations in the central North Island generating about 2,600 GWh a year, enough renewable electricity for about 330,000 homes. Its Turitea wind farm (60 turbines, 221 MW) equals about 2.5% of New Zealand's renewable electricity. It plans a geothermal expansion of up to NZ$1 billion, expected to add about 1 TWh of new baseload (about 125,000 homes) around 2030.

Main narrative
One person’s story (N1)
+ A single story
Daily life that could rely on fossil-fuel electricity. Mercury NZ meets it with 100% renewable power from hydro, geothermal and wind. The benefit appears for nature and future generations: its five geothermal stations in the central North Island generate about 2,600 GWh a year, supplying about 330,000 homes with renewable electricity.

Watching (unconfirmed; not counted in the assessment)
- A listed, for-profit utility
- the generation plus depends on siting
- the environmental impact of geothermal and wind, and it also has a gas-retail business.
Looking ahead (not included in the assessment)
- Expanding geothermal (up to NZ$1 billion); adding wind; care for geothermal and wind's environment; a full transition away from fossil fuels (gas).
A second look
The plus is generating and supplying 100% renewable electricity, an effect on nature and future generations, backed by five geothermal stations, about 330,000 homes' worth and the Turitea wind farm. But it is a listed, for-profit utility, the generation plus depends on siting, and the environmental impact of geothermal and wind and a gas-retail business are reservations. Weighing the genuine, large-scale renewable-electricity plus, B/high.

How to read this assessment
A Independently verified +, with no confirmed −
B Leans +, with independent backing
C Mixed. A confirmed − sets the ceiling, or much is unverified
D A serious confirmed − sets the ceiling
E A serious − reaches the core of the organization
F Serious and systemic, with little redeeming +
G Only extreme cases
Out of scope An entity whose core purpose is illegal
On hold Independent evidence is scarce on both + and −
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
