By monitoring your energy use through accurate metering you can target inefficiency and achieve significant energy savings.
To undertake a full MM&T program you will need to have access to half hourly meter data (showing your consumption in half hour blocks) so that you can identify when wastage is occurring. Larger electricity sites have half hourly metering as standard. However, gas and smaller electricity sites typically have less regular metering and may require upgrading to get higher quality data.
You can find out more about the different types of metering and about analysis of your meter data by clicking on the links below:
Electricity – half-hourly metering
Sites with a peak load above 100kW have half hourly primary meters providing good quality data for energy management. These sites can access their data via their energy supplier or data collector.
Electricity - non-half-hourly metering
Smaller sites with a peak load below 100kW have non-half hourly primary meters which can only be read manually. These sites will frequently have estimated bills and may need to upgrade to smart metering or half hourly metering to get good quality data.
Gas metering
Most gas sites have manually read meters which provide limited data for energy management. Upgrade to smart metering can be desirable to get good quality data.
Gas and electricity: smart metering
Smart meters are an emerging technology which can produce automatic, regular, meter data for small electricity and gas sites.
Sub-metering
Large sites use sub-metering to understand and closely manage their energy consumption throughout their facilities.
Data analysis
Data analysis techniques which lead to savings identification include correlation with production volumes, degree days, analysis of peak and base loads and benchmarking.
