We developed a national residential customer segmentation model for Aotearoa. It combines actual electricity usage data from participating lines companies with 2023 Census data to create a consistent, nationwide picture of how different households use electricity, their ability to pay, and their likely needs. This report also overlays research exploring customer attitudes related to affordability, energy-saving behaviour, solar, EVs and home energy management systems.

This annual report summarises our mahi and impact between 1 August 2024 - 31 July 2025. With just six people, we’ve produced a huge amount of work — including 53 submissions lodged on behalf of the distribution sector this year alone. We'd like to thank our members and the many working groups across lines companies that engage with us every day. The quality and depth of feedback we receive truly strengthens our advocacy.

Alongside South Island EDBs, we engaged DETA Consulting to forecast demand and potential sites for EV journey charges in the South Island. At a maximum – only around 107 additional 50kW journey chargers are required for the South Island.

With the Future Networks Forum, we've commissioned a report that explores potential Distribution System Operation (DSO) models for Aotearoa. It sets out possible paths for how DSO could evolve here and raises the key questions we’ll all need to grapple with as DER (like EV chargers, batteries and solar) continue to take off. The report is intended to be a discussion starter. We’re not claiming to have the answers — but we think these options are a good place to start the kōrero.

The Briefing the Incoming Minister (BIM) outlines key strategic opportunities and issues facing the electricity distribution sector here in Aotearoa.

There are a huge number of acronyms and terms used in the electricity sector. This glossary outlines many of the terms regarding electricity connections and electricity pricing.

This report was commissioned by ENA and undertaken by BECA. It looks at the rising costs of Temporary Traffic Management (TTM) for lines companies in New Zealand. The data highlights that, on average, the costs of temporary traffic management per day has increased around 208% from 2019 to 2024.

This annual report summarises our mahi and impact between 1 August 2023 - 31 July 2024.

We commissioned research to model what electricity demand peaks might look like for Aotearoa up to 2050. Using Climate Change Commission forecasts and data from the Electricity Authority and lines companies, the research from Sapere maps out three scenarios: naïve; energy-optimised; and network-optimised.
