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

Other DSM initiatives …….

AG DSM pilot

project (BEE)

• Proposed scheme of Replacement of existing pump sets by

energy efficient pumps with BEE support under ESCO

• Estimated savings as per BEE of 16.7 MUs is at total cost of Rs.

7.85 Crores for replacement of 2124 pumps on single 11 KV

Mohanpur Feeder in Kurukshetra

• However , in spite of repeated follow up, no response from

ESCOs due to absence of credible Baseline date.

• Feeder segregation and HVDS scheme for Separated AG feeders and metered DTs provides platform for

implementing further DSM measures achieving reduction of demand

• To change the old and inefficient pumps, Implementation of AG DSM through ESCO routes is initiated by

DISCOMs; Concerns about the post supply liability of services observed between suppliers
