Release No. 48
Online tool to make electricity lines companies’ performance data more accessible
The Commerce Commission has today launched a new online data visualisation tool to make information about the
performance of the country’s 29 electricity lines companies more accessible.
The tool uses Tableau data visualisation software to present information on each lines company’s revenue, profitability,
capital and operating expenditure, and network reliability, including the duration and frequency of power outages. The
tool presents data that the regulated lines companies have been required to disclose over the past five years.
Commission Deputy Chair Sue Begg said the release of the tool builds on the Commission’s decision in June this year to
publish annual one-page summaries of each company’s performance.
“This project aims to make the performance of electricity lines companies more easily understandable. By shining a light
on their performance we hope to provide them with greater incentives to improve their performance for the long-term
benefits of their customers, ”Ms Begg said.
“We welcome feedback on the usefulness of the tool including its content, presentation, usability and functionality.
We plan to build on it over time, by adding more data on asset condition, as well as exploring ways to allow easier
comparisons between lines companies.”
