For all those who have been waiting to actually see what it would be to have a grid-connected solar power system, there is good news. Till now, we have only spoken about a concept of net-metering in Delhi (refer), but now we have a demonstration of the concept (refer).

After the push coming from end customers, net-metering is finally happening in Delhi at National Productivity Council. This is the first site to have implemented net-metering and has also received its first bill.

Finally, looking at a real bill taking incorporating ‘net-metering’ will clear the confusion around what it really looks like. Following is an analysis:

BSES net metering
Second page of the BSES generated electricity bill

On the second page of your bill, you will be able to see ‘Net-metering details’ and table with sections as follows:

  • Export reading: This gives you an estimate of the units that have been exported to the grid when excess solar power has been generated and fed back in three time slots – ‘Normal’, ‘Peak’ and ‘Off-peak’.
  • Import reading: This gives you an estimate of the units that have been imported from the grid when the solar system was not generating any or enough electricity, in three different time slots – ‘Normal’, ‘Peak’ and ‘Off-peak’.
  • Net difference: This is the difference in the number of units consumed from the gird minus the units exported from the solar power plant (excess generation).
  • C/F Units: This section gives you the number of net-exported units, or the ‘carry-forward’ units. These are the units that are carried forward to the next month and treated as net-exported unless net-export exceeds net-import. In this case, the consumption (net-import) has been more than what was fed back to the grid (net-export), hence, C/F units are 0.

Calculations

  • Moderated units: This section provides you your net-consumption by calculating ‘equivalent units’. Instead of charging a different tariff for different time slots (normal, peak, off-peak), peak and off-peak units are ramped up and ramped down to calculate the equivalent number of units generated in the ‘Normal’ time slot. So, the peak units are increased by 20% and off-peak units decreased by 25%. In the above case the units in the ‘Net-difference’ section is ramped up and ramped down respectively to match the units given under ‘Moderated Units’.

So, now that you have a sample right in front of you and a demonstration ready, we’re hoping you feel more comfortable with the idea of going solar.

If you think you’re ready to go solar, ask for a free proposal from our end, and we shall revert to you within 24 hours. Click here to place your request.
