hahaha ... good luck with that! Our NORECO bill is almost a foot long, the actual charge for KWH power usage is not that bad, but then there are a LONG list of additional charges included in the bill: Generation System Charges; OGA charge; GRAW charge; ICERA charge; TAFPPC charge; Transmission System Charge; OSLA charge; Distribution System Charge; Supply System Charge; Metering Charge; Metering System Charge; OLRA Charge; Lifeline Charge; NPC Debts charge; Missionary Electrification Charge; Environment Charge; MCC RFCC Charge; followed by a list of VAT charges. By the time all of those charges are included, our KWH charge is less than half of our Total Charge. I have no idea what almost any of those charges are, or how they are calculated, many are several hundred pesos. I think that NORECO is regulated in what they can actually charge per KWH of power, so then they just make up a long list of add on charges in order to get the total bill up to the amount they want.

 

That's ok, we'll just divide the bill by 3 amounts but the question is how ?

GaryJohn, basically your problem has two aspects:
q1. how do I divide the bill over the three submeters, and
q2. are the submeters accurate
a1. that isn't all that hard, just read the 3 submeters on a set date in each month, calculate the difference from the previous month (subtract), then add up the three difference measurements, then that total use represents the entire noreco bill, so it's simply N*a/(a+b+c) is the amount for submeter a, similar for submeters b and c (where N is the amount of the Noreco bill).
a2. To know whether your submeters are accurate you'd need to time your submeter measurements to be on the same day that Noreco reads the main meter, and then a+b+c should be the same as the # of kwh on the Noreco bill.
If there's just a few kwh difference then you're fine, if the difference is a lot then one of your meters might need replacing.

 

Thanks, I'll work on that
