RSM

From April 2025 to March 2026, 419 organisations certified their electricity through BraveTrace, up from 393 the previous year. During the same period, the number of New Zealand Energy Certificates (NZ-ECs) redeemed increased by 19%, with BraveTrace now certifying more than 6% of New Zealand’s total electricity production. As a result, the gap between the…

The number of energy users that purchase New Zealand Energy Certificates (NZ-ECs) continues to grow strongly. There are changing trends in energy user requirements including an increased focus on purchasing NZ-ECs from devices that meet RE100 requirements. With the increased demand for NZ-ECs the Residual Supply Mix (RSM) is now 5.47% more carbon-intensive than the…

We now see a more carbon intensive RSM, which is 4.46% higher than the NSM. The gap between the two has widened from 3.14% the previous year. As these figures continue to diverge, non-certifying businesses face higher reported scope 2 emissions.

More and more, businesses are being asked to measure, report and reduce their emissions. In some cases, businesses can achieve these reductions themselves – by planning fewer plane trips, doing more video-conferences, etc.

People interested in either buying or selling a New Zealand energy certificate (NZ-EC) for the first time often ask the same question, “What is a fair price for an NZ-EC?”

Certified Energy will be trialling the calculation and presentation of a monthly Residual Supply Mix – summarising the nature of electricity generated and supplied to consumers via the national grid in each month.

In this issue: The Residual Supply Mix for 2020/21 is published, draft rules for certifying renewable gas out now for comment, Toitū Envirocare recognises energy certificates, and we’ll be speaking at the next Energy Trader Forum.

Recently, we announced the completion of the 2020/21 Production Year. As a final step in the end of year process, we have now calculated the Residual Supply Mix (RSM) for the period from 1 April 2020 to 31 March 2021 for electricity certification. Producing the RSM is a key function of our role as certification…
