What is DSM?

DSM or Demand Side Management is initiative that electricity providers (distribution utilities) take to manage and modify their customers’ electricity consumption through incentives and education to the consumers. As part of this initiative, utilities offer discounts on energy efficient appliances, help customers in electricity consumption monitoring and also educate customers on saving electricity.

What does Tata Power Offer?

Having access to big number of customers, Tata Power strikes deal with manufacturers to provide deep discounts on energy efficient appliances. For manufacturers a bulk order provides much needed scale to produce the appliances at a lower cost. In past, Tata Power had partnered with appliance manufacturers like Havells India for ceiling fans, OSRAM for T5 tube lights and Carrier India for Air Conditioners. Currently the program for Ceiling Fans is still running and can be availed on following URL (only for Tata Power Customers in Mumbai):


Why would Tata Power want to reduce your electricity consumption?

A common question that people ask is: why will utility want to reduce my power consumption? And a quick answer to this is: Electricity consumption is increasing drastically and the production is not growing up at that pace. To make sure that there is sufficient supply for the demand, utilities have to make sure that they help their customers manage their power consumption. It is not that they reduce their profits by helping customers reducing consumption, but they do this to make sure that they are able to supply electricity to all customers as per their demands.

Another problem that utilities face is of peak power demand. There are certain times in the day when the demand for electricity is at its peak. During these times, utilities have to purchase power at very high cost, much higher than the price paid by consumers. To reduce the peak power demand there are two options. Either they reduce the power demand at the peak hours or overall reduction in power demand. While programs such as exchange program on ceiling fans result in overall reduction in demand, programs such as thermal storage result in shift of demand from peak hours to off peak hours.

Hence, by participating in such programs, you not only reduce your own consumption but also help your utility manage the load better.

Benefits of Participating in such programs:

  1. You can get 30-50% electricity savings by using energy efficient appliances. And it does not reduce your comforts.
  2. You get huge discounts on energy efficient appliances (at times up to 50%) that makes your payback early and you recover the extra cost that you pay to buy the appliance in a much shorter duration (due to savings in your electricity bill).
  3. You need not worry about your old appliances as most of these programs are exchange programs and the old appliances are taken away.

All in all, such programs as a win-win for customers, utilities and the country.  So if you are a Tata Power customer in Mumbai, do avail the benefits.

Hi Annie,

You will have to contact Tata Power customer support for this issue. Bijli Bachao is an independent entity with no relation/affiliation with Tata Power.


Thank you for your prompt reply



I have a room of 10 x 10.5 ft. with ceiling height of 9 ft. at top floor in south west corner having two large window in both south and west sides at Kolkata. Ac may run for 6 to 10 hours a day for four months in a year during summer. I am interested for inverter split AC. But my problem is to put the outside unit at a suitable place. Can I put it in the wall of my bathroom which is having good window facing south. Otherwise I have to put at a longer distance of 20 ft or more. Pl. suggest me for the best option for tonnage also. I am waiting for your response.

Best regards.

Hi Mr Banerjee,
According to our calculation your room requires 1 tons of cooling. So you can go for 1/1.1 ton inverter AC.
While placing the outdoor unit just make sure that it is not placed in an area which heats up quickly and the area must have proper ventilation for heat to transfer from outdoor unit.

You can look at these 1/1.1 ton inverter ACs:

brand model eer_ratio tonnage price
HITACHI RAU013EUEA 4 1 41980
HITACHI RAU013IUEA 4 1 51111
HITACHI RAU012HVEA 4 1 48690
CARRIER Octra Inverter (1.0T) 3.83 1 44800
SHARP AH-XP13PHT 3.83 1.1 NA
SHARP AH-XP13PMT 3.83 1.1 37896
SHARP AH-X13PET 3.83 1.1 32346
SHARP AH-XP13LV 3.83 1.1 31700
HITACHI RAU012HUEA 3.8 1 40900
DAIKIN FTKM35PRV16 3.63 1 43450
HITACHI RAU012KVEA 3.63 1 43190
DAIKIN FTKP35PRV16 3.46 1 37690

I did research for split ac and i find three brands suitable for me LG, Samsung and voltas. the model no of LG and Samsung are are as follows LG LSA5ST3D1, Samsung-AR18JC3ESLWNNA. Samsung is providing 5 year condenser warranty and extra gas refilling between 2 to 5 year and providing free installation till 30th April 2015 but i read reviews of Samsung, which were worst.
