Companies rarely understand and in most cases, comfortably ignore the menace of always-ON load. Even when the premise / office is not occupied ( say during night hours ), there is a minimal current that is drawn by the premise.
No property can come down to zero current when all operations are shut down, unless all power outlets are physically switched off. With the introduction of surveillance, data centers and other security solutions into each premise, there is a need for power 24 x 7. This leads to something called the always-ON aka phantom load in the premise. All electronic equipment has a minimum standby power that comes with it. Even when the equipment is non-functional yet powered, it continues to draw this minimal current. Even if it is in milli-ampere range, the presence of several such equipment will add this up to even an ampere or more. Now if there is an always-ON load of 1 ampere, it is bound to contribute atleast 5 kWh ( units ) of electricity every day.
We have seen industries also battle this menace. In some industrial premises, there will be exhaust fans in addition to server rooms and other always-ON areas. These have to work round the clock, which essentially means an added consumption even when the factory premise is non-operational. Once you start monitoring the data, you can easily find the problem-makers and do a fix that will in turn reduce energy usage and help save money.
Continuous monitoring will highlight these wastage points, which serve as starting steps to your journey towards energy efficiency. Monitoring solutions also provide the convenience of tracking these details from across the globe. This is critical for corporates with multiple facilities spread across different geographies.
