Measuring and monitoring your equipment is essential to manage energy use, costs and productivity in your business.

Understanding how and when your equipment uses energy will give you a baseline to track and report improvements, and compare against other sites. It will continuously identify opportunities to:
By making sure your business is energy efficient, you’re doing your part in lowering greenhouse gas emissions.
Call your energy provider or visit their website to check your energy profile from your smart meter. Analyse your energy profile to understand how much energy your facility uses.
Hire a registered electrician or plumber to install gas or electricity meters in your equipment.
Electricity meters are generally simple for a registered electrician to install. A certified plumber may need to partially or completely shut down the plant to install gas meters.
There are three ways to measure your energy use. Measure at the:
Your registered electrician or plumber will be able to find the right metering for your needs.
There’s no point metering your energy use if you don’t monitor it regularly.
To successfully monitor and analyse performance, you need to:
BaselineBefore undergoing energy-saving upgrades, measure how much energy a business, building or equipment uses. This can be used to compare against or regularly monitor for abnormal spikes.
Current transferA static device that produces a secondary current or voltage output used by an electric meter.
Direct-connected meter, or whole current meterA meter used without an instrument transformer that is directly connected to the electrical circuit to be monitored.
Interval dataWhen you download a data from your smart meter, it’s provided in 15 and 30 minute intervals.
Interval meter, or time of use meterAn electronic meter or smart meter records energy data in 15 and 30 minute intervals.
K factorThe ratio of energy registered by the meter and the actual readable output.
kVar (kilovolt amp reactive)The electrical energy supplied to a site, which doesn’t produce meaningful work, but services induction loads (e.g. magnetic field in a motor).
kW (kilowatt)The rate at which energy (power) is supplied to do work. Typical unit of measurement used on your electricity bill.
kWh (kilowatt hour)The energy supplied to do the work. Typical unit of measurement used on your electricity bill.
Meter data agencies, or registered metering providerCompanies that specialise in reading meters and collecting data. The metering charge on your bill will typically be done by these companies.
MJ (megajoules)A unit of energy supplied to do the work. Typical unit of measurement used on your gas bills.
Pattern-approved meterA type of meter that is approved and certified by the National Measurement Institute, indicating the meter meets Australian Standards.
Peak demand, or maximum demandA period where power is expected to be provided at a higher cost. The unit of measurement is kVA (kilovolt-amp) or kW(kilowatt) and is typically used on electricity bills for medium and large customers.
Programmable logic controller (PLC)A computer used to control machinery and processes, which has a microprocessor and input and output circuits.
Soft metersMeters that use software to measure equipment performance specifications with operating data from a building management system (BMS) to calculate energy demand and consumption in real time.
Supervisory control and data acquisition (SCADA)An application that measures a system or process operating data to control and optimise the system.
SubmeteringMetering at equipment level or section level.
Utility meter, or revenue meterA meter used in conjunction with the supply of electricity from the national electricity market by an electricity retailer.
Through your analysis of the energy data, you may come across abnormalities. Find ways to reduce or eliminate them.
Consider times you can turn off equipment when not needed, like overnight and weekends.
Target equipment that uses the most energy and look through our energy-saving tips for equipment.
If you don’t have the in-house expertise to identify energy-saving opportunities, hire a registered electrician, plumber or an energy auditor.
