Introduction

The Commission commissioned a study to assess the electric energy-efficiency potential in New Zealand’s residential, commercial and industrial sectors. The goals of the study were to determine levels of electricity efficiency available in the New Zealand economy and to estimate the cost effectiveness of programmes to achieve these potentials.

The study used a “bottom-up” approach to estimating potential in which the energy impacts of “standard efficiency” technologies were compared to those of high efficiency equipment across different market sectors and building types.

The report findings represent a critical step in the process of understanding the resource potential of electric energy efficiency in New Zealand in which there appears to be significant untapped achievable and cost-effective potential savings for electricity in all sectors.

Electricity Efficiency Potentials Study Roadshow

A series of briefings on the results and implications of the Commission’s electricity efficiency potentials study was held in Auckland, Wellington and Christchurch in April.

The briefings included presentations on the potentials study and what the Commission is doing with the results.
