What is the point of load shedding if people have inverters?

  You actually loaded the power com only wen you charged the inverter
  
  When the power com sheds load your inverter steps in and it gives you power for 10 hours or so At that time the Power COM is not loaded by all the fans and AC that run in your house

  I know, right? I mean, all the inverter did was to shift the load, while increasing it. How did Powercom benefit by that?

  When the inverter turns on your house hold appliances are completely disconnected from the power com And that means the power com has really dropped a little weight here

  Sure. But, as you pointed out, the inverter, when charging, loaded the Powercom. Therefore, the Powercom was loaded extra for the time the power was on, rather than consistently for 24 hours. So their idea of saving power by load shedding didn't work.
  
  See my point?

  I get it now friend Once the battery is charged to nearly 90-95% of its power The charging of the battery stops and so the Power com is not actually loaded
  
  The amount of current drawn by the invertor is also not that drastic compared to your AC and other heavier loads
  
  Your answer is correct Power com is loaded when the inverter charges
  But once supply is terminated the power com is not.
  
  Another thing to mind is that power com is not over burdened to provide this additional load. But too many inverters in an area can be of some issues I think not sure
  
  Maybe #-Link-Snipped-# can help sort this out

  I can't talk in technical terms for electrical..
  
  However, simple reasons I can think of, a decent inverter battery charges in 2 hours, and gives power up to 10 hours. Also, when a consumer is on inverter, there are high chances that he would not use heavy consumption devices like AC, Fridge, Heater, Geysers and that would save some electricity.
  
  Also, If a survey is to be believed (anonymous), unfortunately in India, Power com makes money with only 60% of the home consumers that are legally using electricity. Remaining 40% is used by illegal means and during power-cut that saves some electricity load and money to Power com.

  Well, if the powersystem consists of only two fans and two bulbs, the power company would see no gain with load shedding. The energy they thought could be saved by load shedding would already be used to charge the inverter batteries. In reality, if the efficiency is considered, it would have had to generate more energy than required without powercut.
  
  That is true only if the load is two fans and two bulbs. But it is not the normal case. As cb said, it is the heavy loads like refrigerator, ac et cetera that save much of the energy during load shedding. If there was no load shedding, these loads would have been kept energised by the consumers. There would have been more bulbs and fans that would be energised too. So definitely quite a lot of energy is saved there. And besides how many homes have an inverter.
  
  A 12V, 12Ah battery can supply 144Wh energy.
  Assuming 100% efficiency and battery would be drained completely.
  Total energy saved = (total energy that would have been consumed without load shedding for the load shedding interval) - 144Wh
  
  If normally a refrigerator will be kept on, a few more lights will be enrgised and more ceiling fans will be running,
  total energy that would have been consumed without load shedding for the load shedding interval = power rating of each appliance x load shedding period.

  Good replies to my question. Thank you.
