    Hi everbody

    I read some articles and documents dealing with energy metering systems and some of them propose formula to calculate the payback period of an energy metering system. Of course, to be able to calculate it, you have to assess the amount of energy or cost you are going to save but…How do you assess such value because I found a lot of differences (from 2% up to 20% of the energy bill) when reading the above docs or on internet sites  ??

    Do you have any reference or examples ?

    Thanks in advance

    payback period of energy management system (EMS)?

    i think for energy management system itself, its pretty hard to measure the payback period. but, after we installed EMS, we can then apply many things and installed many other devices (inverter, energy saving light, sensor) that can lead to energy efficiency that we can measure the payback period.

    correct me if i’m wrong

    Installing an Energy Management System is like installing a CCTV Camera in your facility. Technically, you cannot compute the ROI for such devices but it will simply make you aware of your energy profile. From there you can diagnose where you are at in your energy efficiency program and act on it immediately. Just like the CCTV Camera, you will not see the ROI unless an unlikely event happens.
