Metering the energy of each installation allows for a fairer billing system by automatically charging the exact consumption to each user, or tracking the electricity usage of loads.
In the tertiary sector, it is common to distribute energy expenses among all the users based on the amount recorded in the general meter. Depending on the consumption allocation agreement, this practice may lead to the incorrect re-invoicing of energy use.
To solve this problem, sub-meters have to be installed for each of the premises connected to the main meter in order to log exactly how much energy each user consumes. This allows for a fair allocation of the energy consumption that does not rely on estimates.
The installation of MID-certified sub-meters ensures that the energy is measured in the same way as with the general meter, but with individual readings allowing for a correct allocation for re-invoicing purposes.
Pulse centralizer units are installed to collect relevant information from other utility connections, such as water or gas, by reading pulses from any type of meter.
The devices in the Line system paved the way for the iEMS concept, which combines the management of different types of energy consumption and the management of multiple control and maintenance systems (lighting, HVAC, etc.) into a single solution.
Using the communications integrated into sub-meters, they can be connected to the metering and management software to simulate invoices and automatically receive reports on the monthly expense at each connection without the need for human intervention, minimising billing errors.
The iEMS system records all the information on your installation's energy consumption, which it can monitor in real time, display it on graphs, compare data from different periods or display it in data tables so it can be exported outside the application.
If you install Line-EDS devices, you can then create SCADA displays to control all your automation systems from a single device. You can use any web browser or PowerStudio Server software to control and display the status of your installation in real time, change any setpoint and receive alarms to improve the management of all your control systems.
Thus, by installing an EMS/iEMS, you can manage your energy use at all times and do proper maintenance, improving both the operating costs of any facility and the satisfaction of your users.
This type of solution in buildings and infrastructures can help you determine where, how, when and how much energy the different types of loads consume, and separate consumption by zones or uses in order to properly prioritise various actions to improve consumption, starting with those with the greatest financial impact.
By measuring consumption with EMS management software, you can see if the tariff contracted with the electric utility is suited to the reality of the installation. The software can also record and monitor consumption information, as per the ISO 50001 energy management standard. This type of solution can be used to make dynamic, load performance graphs in real time and to assess the progress made after energy improvement actions have been implemented by carrying out a continuous assessment.
The MID certification is essential for those meters used to invoice energy use, as they ensure the reliability of the consumption logs used to bill the end user. The MID certification allows the installation of invoicing systems that are fully certified throughout the European Union.
By installing measuring equipment, you can take a step forward in energy efficiency by certifying your facility in accordance with the ISO 50001 standard by setting up an Energy Management Systems, or EMS.
The ISO 50001 certification will ensure that you are using energy responsibly and in a way that is environmentally friendly and minimises your carbon footprint by reducing greenhouse gases.
