Industrial Energy Efficiency


The industrial sector accounts for close to 40% of the country’s overall consumption of all energy sources. In comparison to other sectors, industrial sites have by far the largest potential for cost-effective energy savings.

Energy NZ has partnered with the Energy Efficiency & Conservation Authority (EECA) to offer a wide range of energy efficiency programmes aimed at identifying energy efficiency opportunities across a broad spectrum of technologies, including:

  • Compressed Air Systems
  • Refrigeration Systems
  • Process Heat Systems
  • Fan Systems
  • Pumping Systems
  • Lighting Systems

A crucial first step in the energy management process is the energy audit — often 15 – 20% savings are identified outright. It is a useful tool for determining whether your company is effectively using its energy resources. Such an audit evaluates where energy is going, and identifies any energy and cost-saving initiatives that could be implemented. Our consultants are accredited by the Energy Management Association of New Zealand (EMANZ) and follow the AS/NZS 3598 Auditing Standard.

Types of Energy Audits (AS/NZS 3598.2:2014):

Type I: Basic identification and rough quantification of main energy efficiency opportunities.
Type II: Detailed and comprehensive assessment of energy consumption, with higher-accuracy quantification of initiatives and better suited to project investment decisions.
Type III: Precision audit of a sub-system or single process within your company, often specifically undertaken to justify major capital expenditure.

As a recognised EECA programme partner, Energy NZ is able to offer EECA subsidies for our industrial energy efficiency services.  Depending on the project, subsidies of up to 40% can be attained. Energy NZ is not an equipment supplier and we therefore offer a 100% objective assessment, allowing for the most cost-effective solutions to your site’s needs.  In many cases, large energy savings can be achieved through little to no capital expenditure.

Industrial Monitoring Systems:

Monitoring systems are becoming more sophisticated and easier to implement. Along with Energy NZ’s expert energy consulting services, monitoring systems are now a large part of the business, with systems becoming more and more prevalent throughout industry. Studies in both New Zealand and around the world have shown that typical energy savings of 2% – 20% can be achieved through implementing a smart monitoring system alone, with average energy savings of just over 10% being achieved. In some standout cases, energy savings of up to 50% have been achieved.
