(DSM) ?

2 For the first time in India, BESCOM started Demand Side Management activity vide General Manager(Tech) Bescom order No. BESCOM/BC-9/310/05-06 dated M/S.International Institute for Energy Conservation(IIEC), Washington were consultants for BESCOM.

3 Demand Side Management is a mechanism to influence customer’s CAPABILITY and WILLINGNESS to reduce electricity consumption. Demand Side Management is a utility program aiming to fine-tune consumer’s energy consumption pattern, according to the utility’s energy production and distribution capacity. Demand-side management(DSM) programs 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.

4 Demand Side Management relies on a combination of using high efficiency equipment and efficient use of electricity through good operating practice. Demand-side management(DSM) 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 of service and comfort.

5 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.

6 OBJECTIVES OF DSM 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.

7 Types of DSM Programs Following three factors 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.

8 Types of DSM Programs For Promotion of various Energy Efficient / DSM methods in the state following steps were taken: National Energy Conservation Day observed on 14th December (G.o.I has enacted The Energy conservation act 2001). Earth Hour observed by all the employees of BESCOM in offices and their residences. Public were also requested to participate. (Earth Hour was observed on 23rd March 2013 from 8.30PM to 9.30PM by switching off all the unnecessary lights).

9 Operational Metrics BESCOM Load Curve

10 Types of DSM Programs Many workshops on DSM measures conducted.
Following are the various NGOs / corporations who involved in saving of Energy Efficient / DSM measures: BBMP (By using automatic timers) NGOs (By spreading the awareness programmes) Industrial / Commercial Advertisers – (By adopting energy efficient measures) Out door advertising agencies for hoardings (By using energy efficient lighting & dimming hoarding lighting after 10PM) Energy Auditing of BESCOM Corporate Office done by M/s. Centre for Sustainable Development, Bangalore.


A Pilot Project was undertaken during for the first time in India under USAID in Bangalore city as desired by BEE.,MOP. M/S. International Institute for Energy Conservation(IIEC), Washington were consultants for BESCOM CFL Purchase Options Under this scheme consumers were encouraged to purchase CFLs directly from suppliers or from BESCOM on a monthly instalment basis paid through electricity bills. Benefits derived Estimated that about 1.81 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.

13 1.a. Bachat Lamp Yojane Scheme :-
Bachat Lamp Yojane, a scheme to promote replacement of CFLs in the place of incandescent lamps under CDM project promoted by M.o.P., G.o.I., was implemented during 2011. The difference amount of CFL cost to be obtained by the implementing agency through CDM in the form of trading CERs. M/S. HPL Socomac private Lt., Bangalore , was entrusted for two rural Circles namely Bangalore rural Circle and Kolar Circle covering 4 districts wide GM(Proc), BESCOM order no. BC-51/F-485/08-09 Dated: as follows.

14 A total no. Of 37.01,368 CFLs were distributed during 2011 as detailed are shown below:

15 The Salient features of the scheme are as follows:
The warranty period shall not be less than 18 months from the date of fixing of CFL to the household. The power factor shall not be less than 0.85 Free replacement of fused distributed CFLs within two years for 6000 hour CFL’s and within three years for 10,000 hour lamps during the life of the CDM project. It will be the responsibility of the successful firm for collection of fused CFLs through buy-back scheme and arrangements for their safe disposal as per environmental guidelines. A maximum of 4 CFLs shall be replaced in exchange of an incandescent lamp (ICL) at a cost of INR 15 per house hold. These CFLs shall be compliant with the existing National Regulations in force viz. IS-15111:2012 (As per BEE and BLY guidelines)


A Pilot Project was conducted during for the first time in the country as follows: Innovative Bescom Efficient Irrigation Pump Sets Program (BEIP) scheme was launched, supported by International Copper Promotion Council (India). M/S International Institute for energy conservation(IIEC), Washington were consultants for BESCOM. The official suppliers were (selected through tender) M/s Kirloskar Brothers Ltd M/s KSB Pumps Ltd M/s Crompton Greaves Ltd A total number of 1074 nos of submersible pump sets were replaced by Energy Efficient IP Sets under the scheme. Manufacturers offered a warranty of 18 months for pump and offered attractive rates for energy efficient I.P.sets.

18 2.b. Agriculture Demand Side Management, WENEXA-USAID
On , BESCOM launched Distribution Reform Upgrades Management (DRUM) project, water and energy Nexus activity phase II (WENEXA II) both conducted under the aegis of India’s Ministry of Power (MoP) and United States International Development Agency (USAID) / India. The DRUM project established a pilot site at Doddaballapur to help BESCOM. Create of excellence which will serve as a model to be sealed up and replicated else where. Electricity used for irrigation pumps is highly inefficient with pump efficiencies of 30% and less. However farmers are unwilling to invest in these improvements because the present tariff regime does not provide financial incentive to do so. Therefore BESCOM has designed and implemented an integrated system improvement and demand side management.

19 Hence BESCOM planned an initiative called replacing inefficient irrigation pump sets by high efficient pump sets on HVDS feeders at Doddaballapur Sub-Division as a pilot project M/s ENZEN Global Solutions, an ESCO was engaged for replacement of existing IP sets in Doddaballapura on11KV feeders under USAID - WENEXA. This ESCO Agriculture Demand Side Management model was designed by BESCOM in association with USAID-PA Consulting. BESCOM was able to successfully establish a system of appointing ESCO and has been awarded with “National Power Award-2009” under category “ENERGY EFFICIENCY, CONSERVATION AND DEMAND SIDE MANAGEMENT” for Agriculture Demand Side Management initiative.

20 This pilot is the first of its kind in India to undertake Agriculture.
Demand Side Management under ESCO model. A total number of 277 inefficient Pump sets at metered locations in Doddballapura Sub-Division were replaced by High Energy Efficient Pump Sets. BESCOM has saved Million units from this project between April 2011 to June 2013 at Doddaballapura and the project details are mentioned in the following slide:
