Meridian Energy is New Zealand's largest electricity company, generating from 100% renewable sources only. It supplies about 30% of the country's electricity from hydro, wind and geothermal. It is advancing a '7 projects in 7 years' renewable build—the 176 MW Harapaki wind farm is operational, a 100 MW grid-scale battery at Ruakākā is complete, and a 130 MW solar farm is under construction. It plans to invest NZ$3 billion over five years in new renewables, storage and infrastructure, with SBTi-verified science-based targets (50% cut in Scope 1, 2 and relevant Scope 3 by 2030, 90% by 2050). Against a backdrop where about 85% of New Zealand's electricity (2024) is renewable, it pushes toward 100%.

Meridian Energy: 100% renewable—New Zealand's largest electricity from wind, water and geothermal. The letter is B; certainty is high. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q3; estimate based on public information.)
Main narrative
One person’s story (N1)
+ A single story
People and future generations who want to live on electricity free of fossil fuels. Meridian generates from 100% renewable sources only, supplying about 30% of NZ's electricity. The benefit appears for nature and future generations: it is adding '7 renewable projects in 7 years' and investing NZ$3 billion over five years in renewables and storage.

Watching (unconfirmed; not counted in the assessment)
- A listed, for-profit electricity company
- the effect of large-scale hydro/wind on ecosystems (river flows, birds) is a watch item common to renewables.
Looking ahead (not included in the assessment)
- Completing the 7-in-7 plan; stabilization via storage; care for rivers/ecosystems in hydro; contributing to NZ's 100% renewable goal.
A second look
The plus is an effect on climate, nature and future generations through electricity supply free of fossil fuels (Nature, Future generations), backed by the real scale of 100% renewable, NZ's largest, and SBTi verification. But it is a listed, for-profit electricity company, and the effect of large-scale hydro and wind on ecosystems (river flows, birds, etc.) is a watch item common to renewables. Weighing the genuine, large-scale decarbonization 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.
