Electricity Saving Tips For Homes And Offices

Online Electricity Bill Calculator – For all states in India

By on September 26, 2014
This article is also available in these languages: hi Hindi

For most of us, electricity bill is needed just to check the final amount and make the payment. We at Bijli Bachao asked a lot of our acquaintances about how much they understand their electricity bills, and we found hardly a handful who did understand it. And in spite of understanding the bills, not many knew how much they are spending per unit (or 1 kWh) of electricity.


It is very important to know the per-unit cost of electricity as it helps us in understanding how much we are spending per appliance at our home. It is important to understand the monetary impact of any electricity efficiency measure we take. It is also important to understand various components of electricity bills and what is their contribution to the total electricity bill. In a bid to help people understand the same, we have created this online electricity bill calculator that will help people understand how much they spend on various appliances every month and how they can save by doing various activities. Please make sure that you read about the calculator below before using it.


Please note that this tool currently works only for domestic tariffs.


Enter the information below from your electricity bill

Links to check latest per unit electricity rates in various states in India

Steps to use the tool:

1) Select Utility: Once you login, the first thing you need to do is select utility. Select your state, district and utility and the system saves your information for the user session automatically.

2) Enter Units: Enter this value as shown on your electricity bill. This shows up as units consumed.

3) Select Phase: Select if you have a three phase connection or single phase connection. This information is also available on the electricity bill.

4) Connected Load: It is decided by the utility based on appliances you have at your home, please see our article on connected load to get more details.. It is also mentioned as sanctioned load, load, connected load, or approved load. If the load mentioned is in Watts (it is a number is 100s or 1000s) then divide it by 1000 and enter it.

This calculator will help you:

1) Understand various components of your electricity bills.

2) Understand how much you are paying per unit (1 kWh) of electricity bill.

3) Understand how much you spend on various appliances like lights , air conditioner , refrigerator ,  tubelight , computer , set top box , fan , etc. Please note that we have taken approximate usage of these appliances based on how it is used normally in houses. Actual amount may vary as per your use. The values are just a representation.

4) Understand savings if you switch from inefficient to efficient appliances. Even these values are approximation based on general usage. We are in process of building tools to help you get to better values as per your consumption in future.

The tool has been built with latest tariff data available from all the state electricity boards in India and has maximum information as available on internet and through our contacts who helped us with sample electricity bills from various states. Certain values have been rounded to have better readability and so it may not match exactly to your electricity bills but will be very close.

The tool covers following bill components:

1) Energy Charge: This is the per unit electricity charge that you pay on your bill. It is mostly defined slab wise and the cost increases as units on electricity bill increases.

2) Fixed Charge: This is mostly dependent on the connected load that the utility provides you. Connected load is typically calculated as sum of wattage of all the appliances that you have at your home. The utility allocates this much amount of electricity for your home and that is why the fixed charge is applicable.

3) Electricity Duty & Tax: This is the government tax for using electricity. Duty is applicable per unit of electricity consumption and tax is applied on the whole bill amount.

4) Meter Rent: Rent that you pay for having meter at your home. Rates are different for single phase and three phase connections.

5) Wheeling Charge: The tool also helps you find out how your bill gets impacted if you move from Reliance Energy to Tata Power in Mumbai. Wheeling charges are applicable for the switchover.

6) Minimum Monthly Charges: In some states if the consumption is less than a certain amount, minimum monthly charges are applicable, which means that the bill amount cannot be less than minimum monthly charges.

The tool does not cover following elements:

1) FAC (Fuel adjustment charge) or FCA (fuel cost adjustment) or FPPCA (Fuel and Power Purchase Cost Adjustment): This is the amount which utilities apply on bills based on varying price of fuel or Coal. Every month this value is different and is derived based on the current cost of Coal. Typically this a few paise per unit.

2) Arrears/Interest and Other Charges: If your electricity bill has old payment pending and interest on the same, or any other charges, then those will not match from the output of the tool to your electricity bill.

The tool currently in beta stage works only for:

domestic LT (Low Transmission) connections with a connected load between 0 and 20 kW and has been validated for following states: Andhra Pradesh, Assam, Bihar, Chandigarh, Chattisgarh, Gujarat, Haryana, Karnataka, Kerala, Madhya Pradesh, Maharashtra, New Delhi , Rajasthan, Tamil Nadu, Uttar Pradesh and Uttarakhand. It also contains information for following states but has not been validated: Arunachal Pradesh, Goa, Himachal Pradesh, Jammu and Kashmir, Jharkhand, Manipur, Meghalaya, Mizoram, Nagaland, Odisha, Punjab, Sikkim, Tripura and West Bengal. Please feel free to play around with the tool and provide feedback to [email protected]

    but your website calculator says its 877

    so who is lying your website or company ?

  2. Anjum says:

    Hi Abhishek, I wanted to know about the unit consumption of samsung refrigerator model no. RR21J2415SA/TL/2015 per month. it runs 24*7.

    • Abhishek Jain says:

      Hi Anjum,
      Samsung refrigerator model no. RR21J2415SA/TL/2015 consumes 208 units/yr. Therefore it consumes 17.33units/month. This data’s are under test condition and typically a standard refrigerator consumes 30% more electricity in regular usage.

      • Anjum says:

        Thank you Abhishek for such a prompt reply!!! I have one more doubt. I have purchased this refrigerator 8 days ago. and the meter reading is 19 unit in this short span only. This refrigerator runs 24*7. other than that i uses one fan- 15hrs, one tubelight-8 hrs, two cfl (25watt)-2hrs. Is my electric meter is running fine? I think there is some serious problem with the reading.

        • Abhishek Jain says:

          Hi Anjum,
          According to our calculation the units consumed by the appliances you have given is 2.6 units/day. So for 8 days it is 20.8 units. So your meter is working fine.
          You can look at these table to see the units consumed by your appliances per day.

          Appliances Wattage Usage in hours Units/day  
          Fan 90 15 1.35  
          Tubelight 50 8 0.4  
          2 cfls 50 2 0.1  
          Refrigerator   24 0.75  
              Total 2.6

    is electric sub meter legal to install in house built to provide 9 rooms to students on rent,

    • Abhishek Jain says:

      It is legal to put submeters if you are giving rooms on rent. The electricity distribution company will collect bill only for one main meter. You will have to divide it and collect bill from your renters yourself.

    2) what is the time period of checking meter by power suppliers??

    • Abhishek Jain says:

      Hello Ms Agarwal,

      Reliance Energy has monthly billing, so they should check meter every month. As for other things I would suggest to read this report (if it can be helpful): http://www.prayaspune.org/peg/2013-02-21-09-18-33/item/download/118_341560a5872ca7743a629e31b524576f.html

  11. kuldeep says:

    if i have more than one meter in my house than regulatory surcharge and energy tax will be charged separately for all or combined for all

    • Abhishek Jain says:

      That is right, it will be charged on every meter. Every meter will have its own bill and regulatory surcharge and energy tax is on the bill.

  12. ravindra patidar says:

    1 unit(1kwh) = how much cost (in Rs)

    • Abhishek Jain says:

      Hi Ravindra,

      It will depend on your location (city/state) and your usage. Electricity rates are slabbed, i.e. if your usage is less the cost per unit will be less, if your usage is more, cost per unit will be more.

  13. narendra says:

    How many units are consumed per hour by 32 and 42 inch lcd tv of LG

    • Abhishek Jain says:

      32 inch LCD should be about 100 watts and 42 inch about 130-140 watts. So a 32 inch would consume 0.1 units in an hour and 42 inch would consume 0.13 units.

  14. Rushabh says:

    I rented a single room with submeter and total units are 65 only… so its not above 100 so i have to pay only 297 but ower said that you should pay 7 Rs. per unit. but i only use on tube light , one fan, 1 laptoip…plz help me sir

    Recently the CESC(my electricity service provider in Kolkata) has replaced our street transformer.After this,my house electricity meter shows a line voltage of about 253v to sometimes 257v.
    Can it increase my electric bill?

    • Abhishek Jain says:

      Hello Mr Kar,

      High voltage will certainly increase your electricity consumption and thus your electricity bills. You should complain to CESC about the high voltage.

    Hi Abhishek,

    I cant thank you enough for your patience, time spent and for your efforts in doing such a detailed analysis of my power consumption and giving me valuable suggestions to check any increase in my power consumption. Really nice of you and keep up the good work you are doing for general public like us.

    Just one doubt Abhishek. Can the variation between the old meter and the new readings be so vast like 400 units becoming 900 units for the same power load. Does it mean that all the past readings recorded in my EB book over the past 13 years are questionable. Is it likely that EB will charge me separately for any arrears payable due to this correction. Isnt it a sudden burden on the consumers for no fault of theirs. What is the system followed generally by EBs when they change meters to the consumers. Does such high variation in meter readings happen to all or on stray cases like ours .. i dont know if my questions are pertinent to your scope of study but i thought i will get them clarified. thanks

    What is your opinion on Energy Audit. Will it help to find out the genuineness of our past EB bill .and to identify areas where we can reduce our daily consumption of energy . I read about Energy Audit in this website but couldnt understand the benefits of doing this exercise. thanks

    • Abhishek Jain says:


      I know that electromagnetic energy meters get slow with time. How slow can they get, I am not sure about it. Ideally it is joint responsibility of owner and electricity company to manage the meter. Electricity company should do regular checks. And in many states if there is any discrepancy found in the meter, only the last 3-4 months’ billing is fixed. So certainly they cannot charge you for 13 years.

      Many people complain about high bills with change of meter. One of the point in Arvind Kejriwal’s agitation in Delhi was to check effectiveness of the new meters as many consumers faced high bills when private discoms changed old meters with new digital meters. One of the common complaints in our country against digital meters is that they are faster. But these issues are more common that what all of us think.

      Taking services of energy auditor will be a bit expensive for you. Easier thing would be to buy a kill a watt meter like this one: http://www.ebay.in/itm/like/meco-energy-meter-pg07-killawatt-energy-metering-power-guard-kill-watt-/171170339641?pt=lh_defaultdomain_203 and measure the consumption of your appliances on your own (or do self audit). These devices are very easy to use and understand. You can measure any appliance that goes in a plug point using this device. This can help you validate your bill for sure.

      However let me tell you, that there can be only 3-4 pain points in any house:

      1) AC (the biggest energy consumer in any house, consumes anywhere between 1 to 2 units in an hour). Moving to efficient ones with inverter technology helps a lot. But inverter tech helps when the usage is high (which is not the case with you).
      2) Ceiling Fans. Most underestimated appliance. If AC not used, combined usage of all ceiling fans will be highest in any house. Moving to super efficient fan like superfan (www.superfan.in) can help a lot. Superfan saves 60-70% electricity depending on your old fan.
      3) Refrigerators. In many cases old refrigerators start leaking electricity. This results in heating up of refrigerators. Best is to replace the refrigerator with new efficient one in case refrigerator is heating up. If the refrigerator does not heat up then it may not cause problems.
      4) Water Heaters. Consumption of water heater depends on number of people using hot water and how long you keep the water heater on. Lesser the usage of hot water and the amount of time water heater is kept on, the better it is.

      Rest all appliances are low in power consumption. However it is always better to switch them off from the power plug as soon as they are used.

    Hi Abhishek, First of all, I would like to thank you for such an informative site. I came to know about so many previously not known facts (to me). I have a question regarding AC electricity consumption. I live in Chennai, TN. I have a 1 ton window AC (3 star) in one of my room and the consumption is about 6 to 7 hours a day. How much electricity bill should come on bimontly basis? Please let me know if any other info required.

  24. M K LAKSHMI says:

    Hi Abhishek,

    Thank you so much for your immediate response. I am sending my query again hereunder :

    We are a middle class family using the foll appliances :

    1. 1 1/2 ton AC units of Voltas brand and 3 star rating – 2 nos. ( at any time we use only 1 AC for approx 3 hours usage per day)

    2. 1 Usha Lexus geyser lowest capacity . we have automatic cut off in 15 mins we use it only once a day. My geyser switch will be kept off always

    3. 5 tube lights of which only 2 are used say for 8 hours max per day

    4, 5 ceiling fans of crompton greaves of which 1 is used for 18 hours and 2 are used for 12 hours remaining 2 very sparingly used

    5. 1 whirlpool fridge 165 litres single door used round the clock

    6. 1 tv 24″ color used for 3 hours a day

    7. 1 desktop HP computer (All-in-One model) used for 8 hours a day

    8. 1 RO unit for water filter used for 1 hour a day

    9. 2 mobile chargers used for 1 hour per day

    10. 1 samsung front load washing machine used for 45 minutes (only 1 load) on alternate days as we dont have required volume

    We are using the above appliances for the past 13 years and our bi-monthly EB bill used to be ranging from 300 to 400 units and amounts between Rs.700 and Rs. 1000.00 only so far ie until June this year.

    On 8th July 2014, the EB officials changed our old meter into new digital meter after which our bill suddenly shot up to 1185 units and Rs.5779.00 that too for just month ie july / Aug 2014. When we reported this to the local EB officials, a team landed in our house to test the new meter and simply walked out saying meter is working well. They asked me to sign a report which was greek and latin but I had to sign it to avoid consequences.

    We are perplexed as to how 150 to 200 units per month of consumption suddenly became 1185 units and bill amount rose upto Rs. 5779.00 We cant understand the logic behind this demand. There is no change in our power load nor its usage hours . It has been the same over 13 years. We had to pay the above bill to avoid disconnection.

    We sent a mail to the consumer grievance officer attached to our EB ward explaining the above, but he has just turned a deaf ear to our mail.

    After seeing the exhorbitant bill we cut down our AC usage and have minimised our other loads to a great extent but life has become miserable. Still our units consumed is reading as 585 units today (for about 30 days only) which means on bi-monthly, it would again touch 1200 and odd units costing us around Rs.6000.00 . This is totally absurd and these EB guys are very arrogant to our plea over such huge bills.

    Abhishek can you help us understand whether the EB claim is genuine and how such big numbers could be possible suddenly. Is it due to the meter change. We are both senior citizens and certainly cannot afford such huge EB bills on an ongoing basis . How to resolve our issue pls advise. thanks for your time Abhishek.

      Here is my calculation based on the appliances and usage you have mentioned. I have put assumptions next to the calculation.

      Appliance Wattage Hourly Units Usage Hours Total Units Assumption
      AC 1 1660 1.328 3 3.984 Only 1 AC used
      Geyser       0.75  
      Tubelight 1 55 0.055 8 0.44  
      Tubelight 2 55 0.055 8 0.44  
      Fan 1 90 0.09 18 1.62  
      Fan 2 90 0.09 12 1.08  
      Fan 3 90 0.09 12 1.08  
      Fan 4 & 5 180 0.18 2 0.36  
      Fridge       1.5  
      TV 140 0.14 3 0.42 Assumed CRT TV
      Computer 150 0.15 8 1.2  
      Washing Machine       0.25 Per cycle is 0.5 but the washing machine is used on alternate days
      RO & Mobile Chargers       0.05  
        Daily Total 13.174  
        Monthly Total 395.22  
        Bi Monthly Total 790.44 Margin of error 10%

      As per above calculation (assuming appliance usage and inventory is right), up to 900 units bimonthly looks right to me. However I have assumed that none of the appliances: lights/fans etc are energy efficient. 1200 bimonthly looks on a higher side. But we may be missing some usage (even slight increase in AC consumption can have significant impact, at times refrigerators also cause leakage and get heated up and consume a lot of electricity). But bi monthly usage of 400 units with AC looks highly unlikely to me.

      Now many people feel the difference during meter change. The old electromagnetic meters were a little inefficient and used to get slower with time. Digital meters are generally more accurate. Here are the things I would suggest:

      1) Check the usage of AC: My assumptions are based on usage at temperature setting of about 22-23 degrees. If you keep it cooler then it’s consumption will be more. Also if your room remains open or is not well insulated, or if the room is bigger and the AC is undersized, the electricity consumption will be more.

      2) Check if the refrigerator is getting hot on the sides. Heat released by any appliance means that there is a leakage of electricity.

      4) Check usage of your fans. If you look at the total above, 3 fans in your house may consume more units in a day than what an AC uses in 3 hours.

      As for the complaint, you can reach out to the Consumer Grievance Cell in TamilNadu Electricity Governance Initiative: more details on: http://tegi.org.in/cgrf

      If they are also not able to help you, then you can also reach out to the ombudsman: http://tegi.org.in/ombudsman

      Can you please upload a sample copy of your electricity bill on this link http://bit.ly/1ovHIiS ? Do drop a note once you have uploaded.

      SOP is supply of power or energy charges for the 5074 units.
      Rentals will be for meter.
      ED is electricity duty which is mostly a state tax.
      Octroi — need to check what is this for as no other state applies octroi.

      Are you under PSPCL or Chandigarh electricity dept?

    please let me know if i reduces my sanction load from 240 to 102 can it reduces my electricity bill because i only use load 50

    • Abhishek Jain says:

      Hello Sir,

      Sanctioned load of 240 is too high, is it for residential or industrial connection? Typically for residential connections the load is less than 20 kW. Also the benefit will depend on the tariff structure in your state. Which state/city is this for?

    i live in first floor of a rented house which has sub and main meter.ground floor member and i have a singke electric bill.how to tally the bill monthly with the help of main and submeter reading.how to calculate the amount for us individually.

    • Abhishek Jain says:

      I think the best thing would be to divide the bill in the ratio of consumption. So suppose bill is Rs 1800 and one person used 100 units the other 200 units, then the one with 100 units gives one third or Rs 600 and the other two third or Rs 1200. This will be the best way to do it without any differences.

    Hi abishek, greetings… your explanation are too good… I have a doubt , I ve purchased 1.5 tonn onida 3 star ac and planed to use 8 hours daily, how much units it ll consume bimonthly ,,, thanks in advance

    • Abhishek Jain says:

      It would be roughly (approximation) 1.4 units per hour. So about 11.2 units in 8 hrs. So about 672 units in 2 months.

  33. Umang says:

    What is “arrears credits” in electric bill?
    Arrears credit is = 6710.91 and sub-total = – 6710.91 (minus 6710.91)
    Current Bill = Sub Total 610.83
    Gross total = – 6100.08 , Rebate = 16.30

    Amount payable –
    Upto(4/9/14) = -6116.00
    By(14/9/14) = -6100.00
    After (14/9/14) = -6116.00

    July month bill was 1072.00 that i paid online on 31july.

    In the current bill..it says Last.Paid Amount = 6710 on 6th Aug 2014 ( I am not sure who paid it )

    Whats happening with the bill, I am tenant and have been staying here onwards 1 july 2014. Thanks.

    • Abhishek Jain says:

      Hi Umang,

      Arrears Credit means that extra amount has been paid on your connection which is being adjusted. It may be possible that someone’s amount got wrongly adjusted to your account (human error). You should check with your owner as well as the electricity distribution company to check the details.

  34. Ramsharan Kumar says:

    Dear Sir,

    I have the following appliances in my house and have estimated the kWh consumptions in a month as:

    Appliance No. Watt Hour / Day kWh / Day kWh / Month
    Celling Fan 1 60 10 0.60 18.00
    Cooler with Remote 1 190 12 2.28 68.40
    Clothes Iron 1 1000 0.5 0.50 15.00
    Desktop Computer with
    TFT 22″ Monitor 1 100 3 0.30 9.00
    Fridge 1 200 1 0.20 6.00
    Mobile1 1 0.1 0.5 0.00 0.00
    Mobile1 1 0.1 0.5 0.00 0.00
    CFL1 1 20 5 0.10 3.00
    CFL2 1 15 4 0.06 1.80
    CFL3 1 10 1 0.01 0.30
    CFL4 1 10 1 0.01 0.30

    Total 4.06 122

    But, I am getting more than 200 kWh monthly. I guess the sub meter is running fast. In this regard, you are requested to please correct above calculations and advice me what to do to get correct bill.


    • Abhishek Jain says:

      Hello Mr Ramsharan,

      Ceiling Fan would be 75-90 watts. Desktop Computer would be 120 watts. Cooler may be a little more. And Fridge would certainly be much more. What type (single door/double door), size (volume in lts), BEE star rating, Year (of purchase) is the fridge? Cloth iron will be less as it is on only for 30% time (in an hour of operation it is on only for 20 mins).

      • Ramsharan Kumar says:

        Dear Sir,

        Thank you so much for your kind reply.

        Now, I have one more query that could you please suggest Cheap and best brand for an power sub-meter as I can guess the existing sub-meter is running fast which causes me around 150 kWh per month that should be 110 kWh if all appliances are used in scheduled manner mentioned in my previous post.

        Kindly advise please.


        • Abhishek Jain says:

          Hello Mr Ramsharan,

I am surprised to see my society has raised 700 units after some repair done in electrical meters. What I estimate it should not more than 12-15 units for day.

  52. Moonmoon says:

    Hi Abhishek
    I have recently shifted to gurgaon and haven’t bought my appliances yet.i have the following thing running.
    1 fan – 12 hours
    2 CFL’s- max of 4 hours daily
    1 cooler – max of 3-4 hour daily
    1 exhaust fan- 15 mins daily

    i’m confuse because my landlord recently gave me a bill where in my unit consumption is around 164 units in a month,and he is calculating it @ around 7Rs per unit which comes to around 1148. and i’ve yet not connected my appliances like TV, fridge,washing machine,AC or any heavy appliances….
    Is the pricing correct for Gurgaon sector 54)

    • Abhishek Jain says:

      Firstly 164 units looks too high, because here is my calculation:

      Appliance Wattage Unit per hour hourly usage total units per day
      Fan 75 0.075 12 0.90
      CFL 46 0.046 4 0.18
      Cooler 200 0.2 4 0.80
      Exhaust 75 0.075 0.25 0.02

      With 2 units per day your monthly consumption should be around 60 units. 164 is too high. Are you using anything else as well?

    • Moonmoon Mukherjee says:

      No…i do not use any other products occasionally an hair dryer for 1-2 min once a week and a phillips iron 5 days a week for 2-4 minutes…but nothing else…i missed it the last time because its usage is so rare…i use absolutely nothing else….most of the time (from morning 9 to evening 9) no-one is at home and we switch off the main MCB from outside so that even by mistake nothing remains switched on…
      i spoke to my landlord to clarify..he says its the latest digital meter that he has installed and its tamperproof…also the motor is also connected to separate line..i’m unable to find any discrepancy and hence i don’t know what to do…he also got an electrician to check the connectivity….

      Now i’m scared to connect an AC or a TV or a fridge :(

  54. Uday says:

    Dear Abhishek,
    I’ve been using a whirlpool refrigerator and Daewoo washing machine at my home in Kerala, India. I’ve bought this from Dubai. It’s 230V, 50 hz rated appliances. Unfortunately, to advise you the model numbers is not possible at this point of time. My question is will the fact of ‘being imported equipment’ affect the power consumption? Will it increase or decrease the power consumption or remains the same compared with similar appliances bought from India. Home is connected with three phase power.

    • Abhishek Jain says:

      Hello Mr Uday,

      I am not sure about energy standards in Dubai but it will truly depend on the model. Energy efficiency standards are different in different countries, however everywhere there is a range. Japan has very high energy efficiency standards for ACs and refrigerators, but it again is a range that overlaps with efficiency standards in India. India’s most efficient ACs are equivalent mid range ACs in Japan. India’s lowest range ACs will not be sold in Japan. So it truly depends.

  57. RAM WABLE says:


    • Abhishek Jain says:

      FSA or Fuel Surcharge Adjustment changes more frequently than the tariff. Tariffs change once in a year whereas FSA changes anytime when the utility feels that they are paying more for buying electricity. MERC (Maharashtra Electricity Regulator Commission) determines the maximum limit for FSA but most of the time this value is determined while billing and is not available in public domain. And that is the reason we have not been able to include FSA in the calculator. Thanks for the appreciation, it really motivates us to do better.

  58. Niru Singh says:

    Hi Abhishek, I had asked if I could use my Samsung Frig without a voltage stabiliser in Delhi.You had kindly responded and asked the model no. I dont have a booklet or and printed material for the fridge. This is a double door model no:SR-S20DTD and is at least ten years old. I got it from my brother as a gift as he shifted overseas..but has been troubling me with low cooling, and erratic performance since. Appreciate any advice, thanks and regards, Niru Singh

    • Abhishek Jain says:

      I doubt that a refrigerator which is more than 10 years old would have higher voltage tolerance. So if you are experiencing voltage fluctuations in your area then you should go for a stabilizer. Else if you are not facing fluctuations, then it may not be necessary.

  59. Piyush Tandon says:

    Hi ABhishek…

    I have two connections 5 KW each.. residential & commercial.
    Residential has 5 A/c connected ( only 2 or 3 are used), fridge, 1.5 HP pump, geyser,2 flat TV ,1 computer,lights and fan 5 rooms…tenant having 2 A/c and fridge (they put both A/c this month)

    Commercial has my consultancy office with 3 A/c, 6 computers,an inverter 3.5 KVA, fridge(2 usually run) and an expansion of one more A/c in future….
    Till date both connection bills showed up MD lesser than 5KW ( surprisingly between 1 to 2) but charged 5KW obviously but this month the bills showed a Demand of 11 and 12 KW (1800 units & 650 units) thus higher fixed charges and penalty…An increase of usage was certainly there..

    Is it possible that such a steep increase possible in KW in MD???

    I am planning to increase my residential load from 5KW to 8KW and get an additional connection of 5KW for my rented portion..

    Am i planning corrected or need to do something else..?? DO i need to give any other information??

    Thanks in advance

    • Abhishek Jain says:

      That’s a lot of load on each connection.

      If the ACs are 1.5 ton ACs, then each of them would be about 1800-1900 watts or roughly 2 kW each. So 5 ACs can be 10 kW. Fridge would be another 500 watts. 1.5 HP is another 1200 or 1.2 kW. Geyser would be another 2 kW. 2 Flat TVs would be 120 watts each. 1 computer would be another 200 watts. 5 fans and 5 lights would be 5×75 + 5×55 (tubelights) = 650 watts. So total would be about 10 + 0.5 + 1.2 + 2 + 0.24 + 0.2 + 0.65 = ~ 14-15 kW (if everything is running together). But as not everything will run together, it may come down to 11-12 kW.

      In office 3 ACs would be about 6 kW. 6 Computers about 1.2 kW. 2 Fridge another 1 kW. So total of about 8-9 kW.

      It is possible that they were not measuring it earlier and started measuring it recently. Because it is not possible for such steep increase. But your load looks really high.

  60. Piyush Tandon says:

    If one month suffers from MD penalty.. Is the increased demand of load carried to the next months also even if I consume lesser ??

  61. Saji says:


    Sorry to say that there is something seriously wrong with your calculator.
    I am from Mumbai using reliance energy. When you put the “Billed unit” it
    gives you a wrong amount (much higher than what is charged in the actual bill)
    I think you are adding wheeling charges twice.
    Please try it with an actual E bill so that you can get a clear picture and rectify the mistake.
    Good luck and appreciate your work.

  63. Mithun Paul says:

    My name is Mithun Paul. I purchased a second hand refrigerator of kelvinator ( New sterling supreme) and a CRT telivision of Sunsui K2K21. Can u please tell me how many these two consume electricity in one month. And also let me know how much i can save monthly replacing refrigerator with a new 5star and also TV with a LED .. Hoping a reply from you.

    • Abhishek Jain says:

      Hi Mithun,

      Savings on refrigerator will depend on the size and BEE star rating of your old refrigerator. But for TV I can say that CRT TV of 21inch is of about 120 watts and LED of similar size would consume 25 watts. So you save roughly 1 unit of electricity in 10 hours of usage.

  64. prabu says:

    Hi Abhishek, thank you for your knowledgeable information sharing. This post definitely helps to who blindly using power in their home. In my home I am in-charge for Power EB , so far i have paid only around 500 for every two month period. Two months before I bought a New split ac, Onida 1.5 ton 5 star rated, after using this 8 hours everyday now EB charged Rs 2415 (600 units). It was big hit for me, What i thought was 2014 year 5 star rated AC will take very less amount of energy than previous year models. My previous units are 240,260,300 like that. Even I am using 29 degree constantly, It gives good output (chill) otherwise remote is for just switch on and switch off.

    Is there any way to reduce power consumed, I mean is there any method for split ac usage. I am in very hottest place in Tamil Nadu. Please let me know if there is any idea. And anyway simply super what you have done here. Good job !

  65. Shams Ali says:

    Abhishek you deserve a lot of kudos for the information and knowledge expertise you shared on this site with such a simple language, great effort indeed.

    I just want to know how PF ( I believe its power factor) in electronic meter can effect our billing, after going through you site I started electric audit for my home and found our PF is 92 and all other meters in our building in between 71 to 78. Please advice whats going wrong here.


    • Abhishek Jain says:

      Hello Mr Ali,

      I am glad that you found the website useful. Well yes PF stands for power factor and higher the power factor better it is. 92 means 92% or 0.92. Power factor of unity or 1 is ideal. You can read more about Power Factor on this link: https://www.bijlibachao.com/general-tips/what-is-power-factor-correction-and-how-mdi-maximum-demand-indicator-penalty-can-be-avoided.html

      Formula is like this:

      Watts = Power Factor x Voltage x Current

      Watts consumed by appliance remains almost the same. What varies is power factor, voltage and current. But in residential connection we are billed for watt-hour consumed. In commercial and industrial connections, the billing happens on Volt-Ampere (or VA). So if power factor is low, for the same watts the VA value will be high. Improving power factor will decrease the VA value. So you need not worry about PF in your house which however is good as it is 0.92 (although it can reach up to unity).

Apart from that Fuel surcharge 350 and misc. 100 ..My total bill was 2200..Is it possible a domestic meter will get this much bill for 229 units? And for my shock when I checked the bill twice I noticed that the in the bill it was charged as category 2b which means its a commercial meter.When I called my house owner he was blindly arguing it is a domestic meter and the bill is correct one and I should pay it..Whom should I consult now?

    But thick fuse is burning off every 7 to 10 days .
    Please give suggestion what to do.
    Thank you.

    • Abhishek Jain says:

      I think you have gone for re-wirable fuse and if it is burning very frequently means quality is bad. Don’t select the fuse size arbitrarily but as per the maximum load current. Electricians sometime have tendency of providing fuse wire arbitrarily. Better go for HRC fuse or MCB. Never play with the protection and better hire a qualified electrician and provide the protection correctly.

      Hi Ashish,

      Ideally you should have legal connection for you house. By putting a submeter you are getting costly electricity. Someone is basically trying to sell you electricity on their connection and making money out of it (which I think is not legal). Firstly in punjab there is no fixed charges for meter and it is mostly energy charges. Secondly the tariffs are slabbed so if you consume less you pay less per unit and for higher consumption you pay more. In this connection you are getting flat rate which is higher. But you do not have any option as well.

    Hi – I am setting up a restaurant in Chennai, Tamilnadu. The landlord has obtained 20 KW load from EB (Commercial). My electrician says the appliances will use a minimum of 25 KW. Should I ask my landlord to apply for more load? He says I can use up to 40 KW without any problem and it is normal (although approved in 20KW).

      If the assigned load is 25 kW, practically you may exceed the load without having any problems as such. But being on commercial connection, you may get penalty for exceeding the load (depending on commercial tariff plan in Chennai). So it is better to get the load increased.
