Aotearoa generally has around 85% renewable energy circulating through the grid, but
because all electricity is distributed through the same national grid, there’s no way of
knowing whether the electricity you’re using comes from renewable sources.
Meridian is a gentailer, meaning we both generate and retail electricity to households and
businesses. We’re proud to generate our electricity from 100% renewable sources: wind,
water and sun.
Once the electricity we generate enters New Zealand’s grid, it flows through a shared
network of infrastructure and powerlines to wherever it’s needed.
In 2025, 88% of the electricity generated in Aotearoa came from renewable sources like
ours. [1] But that doesn’t mean all of New Zealand’s electricity is always 88% renewable.
Everyone receives a mix of renewable and non-renewable electricity from the grid. That mix
changes throughout the day and across the year, depending on demand and which
generation sources are being used at the time.
Renewable Energy Certificates, or RECs, do not change the electricity flowing to a
customer. Instead, they provide proof that the electricity a Certified customer purchases from
us has been directly matched by electricity generated from our BraveTrace-verified 100%
renewable generation assets. Certified customers can then report their market-based Scope
2 emissions as zero.
We also plan to build more renewable generation and certify more assets over time, helping
us increase the amount of Certified Renewable Energy we can offer customers while
contributing to a more renewable energy mix overall.
