What is Demand Side Management?
•Demand Side Management is a mechanism to influence customer’s CAPABILITY and WILLINGNESS to reduce electricity consumption.
•It is a utility program aiming to fine-tune consumers’ energy consumption pattern, according to the utility’s energy production and distribution capacity.
•DSM programmme consist of the planning, implementing and monitoring activities of electric utility that are designed to encourage consumers to modify their level and pattern of electricity usage.
•DSM programmme relies on a combination of using high efficiency equipment and efficient use of electricity through good operating practice.
•Demand Side Management is the implementation of policies and measures which serve to control, influence and generally reduce electricity demand. DSM aims to improve final electricity-using systems, reduce consumption, while preserving the same level ofservice and comfort.

Objectives of DSM:
1: Reliability and Stability
- DSM provides enhanced reliability to the energy system by reducing overall demand through energy efficiency and by reducing peak demand through dispatchable programs.
- It also reduces transmission and distribution costs relative to a supply side resource.
- DSM increases diversity of energy sources.
2: Low Cost / Affordability
- The cost of DSM is technology specific and varies relative to other supply side resources.
- Dispatchable DSM programs can be called when their cost is lower then alternative market purchases.
- Cost-effective resource planning can ensure that DSM is only procured up to the point where it is cheaper than supply alternatives.
- DSM can also help low-income customers reduce their energy costs.
Types of DSM programmes:
The following three methods reduce energy consumption(kWh) and peak demand (kW), however, emphasis differs
- Energy Efficiency – emphasis is on reducing overall energy consumption and also peak demand over several years.
- Peak Load Management – emphasis is on reducing peak demand consistently over a season.
- Demand Response – emphasis is on reducing peak demand for short periods of time for a few days during the year.
Tips to save energy:
1. Lighting
•Turn off the lights when not in use.
•Take advantage of daylight by using light-coloured, loose-weave curtains on your windows to allow daylight to penetrate the room. Also, decorate with lighter colours that reflect daylight.
•De-dust lighting fixtures to maintain illumination.
•Use task lighting; instead of brightly lighting an entire room, focus the light where you need it.
•Use electronic ballast chokes in place of conventional copper chokes.
•Use LED Lamps instead of conventional incandescent bulbs. A 16w LED bulb can be as bright as 150w halogen lamp. LED lamp consumes 1/3rd of CFL energy and 1/30th energy of incandescent bulbs. The lifespan of incandescent lamps is around 1000 hours while the lifespan of CFL is 8,000 hours and lifespan of LED lamps is around 25,000 hours. LED Lamps are Mercury free and their lifetime cycle is unaffected by switching ON and OFF operations.
2.Fans
•Replace conventional regulators with electronic regulators for ceiling fans.
•Install exhaust fans at a higher elevation than ceiling fans.
•For exhaust fans in diary/poultry industry usage of multi fan axial fans leads to low energy consumption with low noise levels.
•Use BEE star rated energy efficient fans.
3. Electric Iron
•Select iron boxes with automatic temperature cutoff.
•Use appropriate regulator position for ironing.
•Do not put more water on clothes while ironing.
•Do not iron wet clothes.
•Use BEE star rated energy efficient iron box.
4. Kitchen Appliances: Use always BEE star rated efficient electrical appliances.
a) Mixers:
•Avoid dry grinding in your food processors (mixers and grinders) as it takes longer time than liquid grinding.
b) Microwaves ovens:
•Avoid baking large sized food items.
•Unless you are baking breads or pastries you may not need to preheat.
c) Induction Stove:
•Consumes 50% less energy than conventional electric coil/ hot plate.
•Takes less time to boil water than conventional electric stoves.
d) Electric Stove:
•Turn off electric stoves several minutes before the specified cooking time.
•Use flat-bottomed pans that make full contact with the cooking coil.
f) Refrigerator:
•Do not open the door of the refrigerator frequently.
•Make sure your refrigerator or door seals are airtight.
•Don’t keep your refrigerator or freezer too cold.
•Avoid putting hot or warm food straight into the fridge.
•Retire old/inefficient refrigerators and buy new energy efficient star rated energy efficient refrigerators.
•Don’t leave the refrigerator door open for longer than necessary as cold air will escape.
•Leave enough space between your refrigerator and the walls so that air can easily circulate around the refrigerator.
•Use BEE star rated energy efficient refrigerators.
g) Washing Machine:
•Avoid washing with half loads.
•Use optimum quantity of water.
•Use timer facility to save energy.
•Prefer natural drying over electric dryers.
•Dry full loads or reduce drying time for partial loads.
•Use BEE star rated energy efficient washing machines.
5. Electronic Devices:
•Do not switch on the power when TV and Audio Systems are not in use i.e., idle operation leads to an energy loss of 10 watts/device.
6.Computers:
•Turn off your home office equipment when not in use. A computer that runs 24 hours a day, for instance, uses - more power than an energy-efficient refrigerator.
•Optimize brightness of monitors as bright light consumes more power. Studies have proved that minimum brightness consumes 11 Watts while maximum brightness in monitors consumes as much as 25 Watts.
7. Air Conditioners:
•Prefer air conditioners having automatic temperature cut off.
•Keep regulators at “low cool” position or in energy efficient mode.
•Make sure that the joints at windows and doors are properly sealed and insulate the room against loss of temperature.
•Use BEE star rated energy efficient air conditioners.
DSM activities in BESCOM:
1. BESCOM Efficient Lighting Program(BELP):
A Pilot Project was undertaken during 2005-06 under USAID in Bangalore city as follows:
CFL Purchase Options:
- Consumers were encouraged to purchase CFLs directly from suppliers or from BESCOM on a monthly installment basis paid through electricity bills.
Benefits derived
- Estimated that about 1.75 Lakhs additional CFLs were sold during the scheme implementation
- About 100% increase in sales of CFLS was observed compares to the previous year which resulted in:
- Reduction in residential demand to an extent of 10.46MWs.
- This Pilot project encouraged in formulation of Bachat Lamp Yojana in the country.
It enforced manufacturers to give one year warranty to the customers.
This scheme lead to regulation stipulating a minimum power factor of 0.85 for CFLs.
2. Bachat Lamp Yojane Scheme:-
•Bachat Lamp Yojane, a scheme to promote replacement of CFLs in place of incandescent lamps under CDM project promoted by M.o.P., G.o.I., was implemented during 2011.
•Maximum of 4 CFLs per customer were distributed at a cost of Rs. 15/- per CFL.
•The difference amount of CFL cost to be obtained by the implementing agency through
CDM in the form of trading CERs.
•M/s. HPL Electric & Power Pvt. Ltd. was entrusted for two rural Circles namely Bangalore Rural Circle and Kolar Circle covering 4 districts.
