Electricity Saving Tips For Homes And Offices

Know Your Electricity Bill

By on April 27, 2015

It is very important to understand the electricity bill and it’s components to make plans for energy savings. Our electricity bills have quite a lot of information to give us a good insight to our electricity consumption patterns. A good understanding of various components can help one plan for money saving exercise. In this article, we will discuss various sections/information on electricity bills that are important: 

Electricity Bill
  • Tariff / Category: Tariff and Category determine the rate structure applicable on the bill. Typical tariff codes start with LT (Low Tension) or HT (High Tension). LT codes are typically used for residential connections and small offices . HT codes are typically used for bigger industries and complexes. Category in the bill determines if the connection is residential, commercial or industrial. Different rates/slabs are applicable for different tariff codes and thus it is important to validate that the right tariff code is applied on the electricity bill. This information is available on bill header as shown below:bill header
  • Type of Supply & Connected Load: Connected Load is the total pool of supply that is given to a meter. This is calculated in kW (or Killo-Watts). This is the total peak kW given to a meter based on the appliances connected to the meter. This is not your actual energy consumption and only impacts fixed charges on your electicity bill. Connected load also determines if the connection will be a single phase or three phase. If load is more then supply is three phase and thus fixed charges are more. Utilities also charge more fixed cost for incremental connected load. Below is a screenshot from Reliance Energy bill in Mumbai:connected load
  • Units Consumed: Units consumed is the number of kWh (Killo-Watt-Hour) consumed in a month. 1 kWh is equivalent to keeping a 100 Watts bulb on for 10 hrs. This information is calculated by finding the difference between meter readings of two consecutive months. This is the total monthly consumption by all the appliances that are connected to the meter. This is the value that needs to come down in order to reduce the electricity bill. An observation of consumption history can give an indictor of the appliances having higher electricity consumption (typically Air Conditioners increase consumption in summers).units consumed
  • Tariff Structure: It is very important to note the tariff structure on your bill, as this is the best indicator of how the bill can be reduced. Typically for residential and SMB commercial connections, the structure is slab based (unlike industrial connections where units are charged at a high flat rate). The intent behind the slab structure is to reward low energy users and charge extra to those who have high consumption. The slabs are based on the “Units Consumed” that we discussed earlier. As the number of units consumed increase, energy charge changes and also the fixed costs associated with the slab increases. Below is a sample of tariff structure from a bill from Mumbai:tariff structure updated
  • Fuel Adjustment Charge (FAC): As you can see in the tariff structure above, there is a FAC rate applicable at each slab. This is the additional cost of power incurred due to fuel price increments during a year. Fuel in most cases is Coal. As per a study, after 2011, the production rates of coal will decline, reaching 1990 levels by the year 2037, and reaching 50% of the peak value in the year 2047. So invariably FAC will increase till alternate sources of electricity are not developed to a state where they can generate electricity that cheap. So electricity costs will surely increase in future.

Understanding the elements of electricity bill mentioned above can help you understand your electricity bill and will also help you to plan your electricty consumption reduction project. Two things that should be targeted are: Units Consumed and Connected Load. Reduce the two and your electricity bill will surely come down.inforgaphic17

    My house has an Single Phase, someone recommended since the number of appliances you have, it would be better if you could convert to a 3 Phase. Do I need to go ahead and inform the Electricity department that I intent to change or do I go ahead with it with the help of a local electrician, also the house doesn’t have proper earthing and hence the recommendation came. Its more than 20 years old and have currently added an AC, Washing Machine (Fully Automatic) – Front Load and intend to add more appliances to the house. I am from Hyderabad, Telangana.

    • Bijli Bachao Team

      For a single AC, going for a 3 phase connection is not necessary. Only if your total house load is more than 5-7 kW, that is when 3 phase is required. 1 AC would just be about 1800-1900 watts (if it is a 3 star 1.5 ton AC). However if you intend to add more appliances that results in total load to be more than 5-7 kW, then it will be better to go for 3 phase. And for that you will have to go to electricity department (electrician can only fix the wiring in your house, he cannot provide you 3 phase connection). Once you have 3 phase connection, then you will have to call your electrician to fix your wiring in such a way that your house is divided into 3 parts with equal load divided into all 3 phases. He should also fix your earthing as without that there will be danger of people getting electric shocks.

  • Anand Kumar

    I just moved to a rented home few months back in panchkula,haryana. Electricity bill for my place is same from past 10 months which shows only amount to cover MMC. I dont understand why the units consumed is ame and being charged the same amount.please let me know what to do.

    • Bijli Bachao Team

      They are not taking meter reading and thus applying MMC for you. You must put a complaint for this as when they do take a meter reading, your electricity bill will be really high.

  • Ashish

    Hi, We were out of station ou electricity bill come around 50, but after cming and using the flat for 15 days electricity bill still came around 50 , what should i do??(I live in Maharashtra)

    • Bijli Bachao Team

      Hi Ashish,

      The person may not have come to take the reading and would have applied minimum amount. You must ask MSEDCL to take your meter reading and also do make sure that the amount is calculated for two months and not for 1 month (with full units).

  • pranati

    i am from hyderabad,telangana.i was out of station and my flat was lying vacant. so there is no electric consumption. do i need to pay bill for non-consumption also? is there any minimum bill or something like that

    • Bijli Bachao Team

      Yes Pranati there is minimum monthly charge in Telangana. It is Rs 50 for single phase connection and Rs 150 for three phase connection.

    • pranati

      thx for the prompt response BB team. How can i know if my flat electrical connection is single phase or three phase?

    • Bijli Bachao Team

      It should be there on your electricity bill. If you find it hard to find then you can send a scanned copy to us on [email protected] and we will help you find it.

  • ujval

    I am staying in a rented accomodation in Secunderabad(telangana) .I went on a vacation from may 8th to june 6th 2015.Approx a month.units consumed during this period are 118 .what should be the bill for same leaving customer charges or surcharge duty etc .wantvto know the bill according to just the units used

    • Bijli Bachao Team

      Hi Ujval,

      As per tariff in Telangana your first 100 units will be charged at Rs 2.6 and the next 18 at Rs 3.6. So energy charge will be Rs 324. On top of it, depending on your connected load there will be Rs 50 (for single phase) or Rs 150 (for three phase). On top of it there will be taxes and duties.

  • Mageshwaran

    HI i am running a shop in telengana and i am getting huge bills above 7000 rs and i suspect that it is because of 3 phase and i want to know the proce to convert my meter from 3ph to single phase.

    • Bijli Bachao Team

      Hi Mangeshwaran,

      3 phase and single phase has very little impact on electricity bills. Huge bills mostly happen when electricity consumption is high, which means your appliances are consuming a lot of electricity. You can contact customer support of your state electricity distribution company to get your connection converted. They can help you with the process.

    • mageshwaran

      Hi Team, my bill has shot upto 9000 now and i am seriously thinking about the conversion of 3 phase to single phase but i need to know if the board would permit me to do so as my contracted load 14.000kw but my connected load says 2.53HP now my question is HP greater than KW or vice-versa. i am so concerned because the same load and appliances are used in my brothers shop in a different area with in hyderabad,but his bills has never gone up over rs3500.i have spoke to the electricity guy about the same he is not keen in hearing as he dosent want to interrupt this huge bills.
      Now tell me the way to sort this problem out and the proper approach to solve the same….

    • Bijli Bachao Team

      Hello Mr Mageshwaran,

      Firstly let me explain you a few things:

      1) 1 HP is 750 watts or 0.75 kW. So 2.53 HP would be 1.8975 kW. So your contracted load of 14 kW is quite high. So you can easily shift from 14 kW to 2 or 3 kW if your connected load is less. You can put an application with your electricity distribution company’s customer care center. If you give sufficient proof that your appliances are less (low wattage and less in number). They should be able to change your 3 phase connection to 2 phase.

      2) However Connected load just impacts the fixed charges on an electricity bill. They do not impact variable charges. Fixed charges in Telangana are Rs 50/kW. So even if you reduce your connection from 14 kW to 3 kW. You will save 11 x 50 = Rs 550 + taxes. Major charges are for Energy Charge which depends on wattage and usage of appliances. Somewhere your appliances are consuming more electricity (either they are energy inefficient or used more than your brother’s shop).

      You need to look at each appliance, their wattage and the number of hours they are used for.

      HI Team,

      Please find my EBill and list of appliances that i use and please help me
      in rectifying this issue as it is getting very hectic on my pocket.

      List OF Appliances Used:-

      1)1 voltas display refigerator and 1
      dislpay icecream refigerator

      2)3 fans

      3)4 tube lights

      4) 4 low voltage dislpay lights

      5) Weighing machine (10kg capacity)

      6) Front lights

      7) Desktop (hardly used)

      I tried attaching my bills to the reply email but it bounced can you share a valid mail id so i send my bills for you analyze the issue

    • Bijli Bachao Team

      Can you send it at [email protected]? Of all the appliances you have listed, refrigerators (both of them) can be the only suspects. Can you check if they are getting hot from outside by any chance?

    • Bijli Bachao Team

      Hello Mr Mageshwaran,

      Firstly one glaring thing that is coming out from your bill is that your energy consumption is 634 kWh but because you have a demand based billing and your power factor is bad (0.67), so you are billed for 634 (kWh) / 0.67 = 946 units. Power factor of 0.67 is quite bad and it can be as high as 0.99 which will bring down your units to 650. Which will bring down your electricity bills by Rs 2500-3000 or so.

      Now your consumption is 634 kWh per month which is roughly 20 units a day. Now if your refrigerator and freezer are fine, they should consume about 2-3 units a day. Let’s take 3 on a higher side. So 6 units for that. 3 fans, each of 75 watts used for 10 hours would be 3 x 75 x 10 / 1000 = 2.25 units per day. Assuming you have 50 Watts tubelights and are also used for 10 hours a day, then it would consume 4 x 50 x 10 /1000 = 2 units per day. Weighing machine should not consume a whole lot of electricity. All other stuff would consume about 1 unit max. So total should be 3 + 3 + 2.25 + 2 + 1 = 11.25 …. but your consumption is 21 per day … which is almost double. A few things that could be causing problems:

      1) If the refrigerator is getting hot then it much be consuming a lot. You may consider buying a new energy efficient refrigerator. You may switch to inverter technology refrigerator and that would reduce your electricity consumption at least by 60% (considering your refrigerator is fine). If the refrigerator is faulty, it can be more than 60% as well, because inverter tech BEE 4 star rated refrigerator consume as less as 0.6 units per day.
      2) Icecream freezer could also be consuming a lot of electricity.You may consider buying a new energy efficient freezer.
      3) You can certainly reduce electricity consumption of your ceiling fans by going for energy efficient BEE 5 star rated fans like Superfan, Havells ES 5 star, Orient High Speed, etc. With superfan you can reduce daily fan consumption by 60%
      4) You may also consider going for LED tubelights. With 18 W LED tubelights, you would reduce your electricity consumption by 60-70%.

      By the way if you do all of above, then your power factor will also improve considerably as inverter tech, superfans and LED tubes have power factor close to 1. To know more about power factor, you may read these pages on our website:



      If you have the most ideal setup (with most efficient appliances and high power factor) then your bills can be as low as 200-230 units (or roughly Rs 2000) (assuming 10 hours of usage of lights and fans). But if you are not ready to make investments in buying efficient products then here are few things that can immediately bring down your bills by 30-40%:

      1) Use a power saver capacitor bank to improve your power factor and get it close to 1. 0.67 is horribly bad.
      2) Decrease your contracted load to 2.5 kW (your connected load is 1.89 kW).

      These two should immediately decrease your bills without changing appliances. But from a long term perspective, it will be great if you get your appliances changed to efficient ones.

    • mageshwaran

      Hi Team,
      Thanks for the response.one more thing my electrician suggesting is that: Now currently all the appliances are running on one phase of the total 3 phase..now he is saying that dividing the load among all the three phases would reduce the bill..is that a correct suggestion bcoz he is asking me to get 720 wire and he will give this 2 fridge connection to those two idol phases.not sure is that right approach please suggest

    • Bijli Bachao Team

      Hello Mr Magesh,

      If you have 3 phase connection, then the ideal scenario is to divide the load amongst all the three phases as imbalance can lead to problems. However it does not result in excess electricity consumption. It can only lead to failure of the line, but cannot result in high electricity consumption. I think you should switch over to a single phase connection and implement the suggestions that I had given. If you switch to single phase, you will not have to spend money on getting the extra wiring.

  • sonam

    When i calculated my electricity bill online through bill calculator there FAc charges were shown nil whereas in the soft copy i am charged and amount is rs 529. So why did online bill calculator showed nil charges then?

    • Bijli Bachao Team

      Hi Sonam,

      FAC is a variable charge that is determined by electricity distribution company every month. It can be different every month and we do not have information about it. So it is difficult to include that in the calculator.

  • Nadeem Shaikh

    I just want to know the connected load funda.. Now my bill shows connected load as 0.70 kW and I have a regular connections in my house i.e.fridge,geysers,1 pc, 4 tubelights, fan, tv
    My society is going for a upgrade of the meter cabin and they want a 3 phase connection. In total there are 30 meters and only 1 person is changing to 3 phase meter but connection will be available to all. An average house here consumes 10 units a day. Also in future I want to install around 1 AC in my house of around 1 ton
    So how much connected load should I have as I think Now it’s too much less. And what impact connected load will have on my bills and what is the procedure to increase it? Please do help as I’m a bit confused now regarding this issues.
    Nadeem Shaikh

    • Bijli Bachao Team

      Hi Nadeem,

      Connected load should ideally be sum of total watts of all the appliances switched on at any given time. It can be sum of wattages of all the appliances you have if you switch them on all the time. But typically it is approximated to 70% of total wattage at least. Now if we look at your appliances:

      Fridge would be about 350-400 Watts (peak)
      Geysers will each be 2000 Watts or 3000 Watts depending on the type you have.
      1 PC will be about 120 Watts.
      Each tubelight would be 45-50 Watts, so 4 will be 200 Watts.
      A TV would again depend on Type but if I assume LED TV then it would be less than 100 Watts.
      1 Ton AC would be about 1000-1200 Watts.

      0.7 kW is super low connected load for your house. In Delhi and UP the utilities are applying penalties for exceeding the connected load and looking at the situation of electric grids across the country it seem soon many states will follow them. To calculate the load, you must sum up all the wattages (divide by 1000 to convert it into kW) and take about 70-80% of that as connected load (assuming max 70-80% appliances will be on at any given time) . In fact the procedure for increasing the same should be simple: you just need to go to customer service desk of your electricity distribution company, give a list of all your appliances and they accordingly estimate the total load that should be sanctioned (there will be simple application for the same).

      You would need 3 phase if your total load exceed 5-7 kW (depending on your state). Some states give 3 phase at more than 5 KW, some give it at more than 7 kW.

  • mahesh


    i am mahesh, Is there any possibility to find the connected load of a house based on the electricity bill units..?

    • Abhishek Jain

      Hi Mahesh,

      Electricity bill units is the actual energy consumption. Where was connected load is the maximum instantaneous power that can be withdrawn. To give you a analogy: connected load is similar to maximum speed at which a car can run (the car may or may not run at that speed), whereas units is similar to actual distance covered (in a certain time). Hope this helps.


  • Vineet B

    Hi Abhishek, referring to the west bengal power distribution company’s bills, the fixed charges you refer above is part of the meter rentals. The fixed charges for residential consumers are Rs 5/KVA/mon which is basically the demand charges and the distribution infrastructure cost to deliver the electricity to the consumer for his peak demand. I’ve a small project running to monitor the electricity consumption/usage in real-time on the cloud. For the same I’m seeking to understand how WBSEDCL calculates the fixed demand charges, i.e. how does it come to the KVA figure for the month, any insight from your side would be appreciable.

    As per my understanding, there are two ways to calculate the KVA, some meters calculate it every 15 or 30 mins to see your peak demand and sets it for the month. Other method is using the KwH from the bill.

    KW = KHW/h

    KVA = KW/PF

    for example you have 300 units for the month on your bill this the KW will be 300/(30*24) = .417

    thus KVA = .417/ .85 (power factor as assumed by WBSEDCL in the absence of a measure) = .4905

    Thus as per the bill its Rs 5 per .4905, how does it calculate the total KVA load for the billing cycle to come to a month cost is what I seek.

    • Abhishek Jain

      Hi Vineet,

      You can check West Bengal’s Tariff order to get more details. It is available at http://www.wberc.org/wberc/tariff/wbsedcl/Tariff/ordnpet2001/index.htm. In general, power factor at most residential houses should be close to 1 as there is not a huge inductive load in any house. In most states the fixed charges are calculated per KW of connected load and there are no demand charges for residential connections. Also for commercial connections, the demand charges are based on the peak demand and it does not have any relation with the units or KWH consumed per month. So I do not think you can calculate it using the monthly units consumed. Connected load or peak demand is mentioned on the electricity bills and that is the best source for you to get that value. Hope this helps.
