How does Net metering work?

Single Phase Meter CL710K20
Single Phase Meter CL710K20

When you are generating power by solar or wind, you might produce more energy than you actually need. This additional power is feed to the power grid and you as customer get those produced units as a credit for later use.
Many utilities worldwide have already implemented such incentives coming together with a NEM (net energy metering) meter, such as our CL710K20.

Do you have already experience with NEM ?

  1. Hi Dear!!! for high tension meter dispay Tariff zero -Tariff four , For Each Tariff Record Active Energy Reactive and Denad Which Tariff Catogory Record Actual Consuotion?

    1. The tariff structure is given by your power company and depends on your contract. If you are in doubt, ask them.
      See more information about tariffs here.

  2. As you know, Chilean electrical tariffs are selected by customers, how in many cases they do not know which one is better for them, then ask their Utility ro recommend the one for them. This is good for Utility but not for users. Can you help us, please, in order to use one rev. meter indirect 0.2% IEC, and sub metering for single and three phases users? This must be tele reading. Thanks-

    1. If you are generating your own power and feed to the grid, the quadrant will be between Q2 and Q3. It depends on the grid load. Your power company will install a four quadrant meter to record power import and export.
      If you have no allowance to export, the meter will record a tamper and bill export on import side. The power company can also decide whether to trip additionally the load switch.

  3. How to know more info about disconnection of meters? Same to have a budget price for single and three phases? Thanks

    1. Thanks for the request, Mariano. My colleague is going to drop you a mail.

    2. Hello Mariano,
      A connection and disconnection command can be sent from the HES. Also disconnections can be due to exceeding maximum demand limits, overvoltage, fraud, and others. It depends on how you have the meter configured. Any other questions write me in my mail.

  4. thank you. Is there cost implication for such a meter with net energy register from a normal meter with export and import registers

    1. It's a firmware function. So there are no hardware cost involved. Nevertheless this function is used for billing purpose. So the additional cost comes from testing, but it's marginal. If this function is used, the utility must test it similar to a register test on a certain percentage (incoming goods control).

  5. Does the meter has separate register to record the net energy or it records on import and export registers?

    1. Patricia, thank you for your question.
      The net energy has it's own register. The OBIS code is 16.8.0
      The calculation is imported energy minus exported energy.
