Importance of DSM in case of Haryana: Substantial
Scope for Energy Conservation
Domestic constitutes 22% share of the total sales in the State
• The Bachat Lamp Yojna resulted in reduction of 10.23 MW connected load and annual saving of 15.73
MUs in Sonepat and Y’ Nagar which have 13% of the total state’s DS consumers
Agricultural constitutes 29% of the total sales in the State
• W.e.f. December 2009 , it has been mandated to use star rated Agriculture Pump. After that all the new
AP connections i.e. 112945 nos. are released with Star rated Pump sets, which constitute 19% of total
installed base of 579338 Nos. AP connections in the state. which clearly indicates huge scope for
Agriculture DSM

Analysis of Load Curve
• The load curve graph is almost flat for the period July-September
• There is small leverage in other three quarters where wecan use DSM measures to flatten the load curve.
• Presently the load curve flattening is being done throughPeak load exemption charges [PLEC] for Industrialconsumers.
• It is observed that peak demand of system is primarily dueto Domestic lighting load and Non-domestic load in evening.For addressing the peak due to domestic and commercialload utilities are planning to implement ToD meteringinitially in Panipat city area under smart grid project.

Technical Support for undertaking Load Research through BEE & EESL
• A MoU has been signed with Bureau of Energy Efficiency (BEE) inJuly , 2014, wherein EESL will hire 2 DSM consultants for UHBVN,the cost of which will be funded by BEE.
• The UHBVN has already conveyed its willingness to allow EESL tohire consultants in July, 2014 .
• As per MoU, EESL will provide support to DISCOMs in followingbroad areas.
– Develop Approach and Methodology for Load Survey, LoadResearch, Load Strategies and development of DSM ActionPlan.
– Provide technical support to the consultants during Load Survey,Load Research, Load Strategies and development of DSMAction Plan.

Load Management Initiatives –Peak Load Exemption Charges [PLEC]
Levy of PLEC on Power intensive Industrial consumers to flatten the
load curve is applicable since 1990’s
• Primary objective is to flatten the curve during peak by shifting
the load to off peak. The PLEC Charges were reduced from Rs 3.80 per
unit in FY 2013-14 to Rs 1.90 per unit by utilities and as per present tariff
order for 2014-15 the applicable rate is as under :-
• Existing PLEC For Normal Consumer charges are :-
– Up to 50% of the Contract Demand :- Rs 1.00 per KVAH
– Above 50% of Contract Demand :- Rs 1.50 per KVAH
• For Open access Consumer PLEC charges are :-
• Up to 20% of the contract demand:-Nil
• From 20% to 50% of the contract demand:- Rs 0.95/Kwh
• Above 50%:- Rs 1.5/Kwh
Load Management Initiatives –Peak Load Exemption Charges [PLEC]-Impact Analysis- Case Study of DHBVN
Average Industrial Load of DHBVN during Day Time:- 960 MW
Average Industrial Load during Night :- 400 MW.
Average Industrial Load during Peak Time[06:30 P.M. To 10:00
P.M.] :- 250 to 300 MW
Impact of Reduced PLEC Charges :- 15% Increase in
Consumption during Peak Load.
DSM implementation: Objective Oriented and Sustainable
Approach
Objective Approach
• Energy conservation by price (through Incentive and Penalty mechanism)
– Through Tariff setting
– Peak Load exemption charges
– Reliability surcharge
– Incentive provisions for Shifting of load to off-peak hours
Peak Load
Management
• Energy Conservation by usage of efficient Equipment (through awareness and
mandatory provision)
– Promotion of CFLs for lighting in High Value consumers
– Mandatory Purchase of star rated equipment
– Mandatory provisions for Purchase of star rated equipment for consumers
Promotion of
energy efficient
equipment
• Energy Conservation by coordinated efforts
– Promotion and distribution of CFLs in low demand consumers
– Rebate on switching over to Other energy sources
– Improved Supply hours & Reliability for participating consumers
Customer
involvement and
Satisfaction
• Integration with other scheme
– Loss Reduction
• Sustainability through Long Term Planning
• Through Innovation;
Cost optimization
