Dem and Response Dem and Managem ent Energy Efficiency Conservation

Dem and Side Managem ent

Dem and Side Managem ent ( DSM) is the implementation of those measures that help the consumers to use electricity more efficiently and in doing so reduce the utility costs. This, in turn, will help the electricity consumers to cut costs. Reduction or shift in energy use during critical periods for short duration delivered immediately Saving energy by taking an action that often becomes a habit Permanent reduction in energy use driven mainly by equipment upgrades Customer Awareness of peak power (KW) demand

Need for DSM and its benefits

NEED FOR DSM

  • Flattened load curve helps

DISCOMs optimize power procurements costs (reduction of surplus power)

  • Reduce overall costs of energy

systems – helps to meet people’s energy needs at a lower cost

  • Preserve the environment

BENEFI TS OF DSM

  • Peak Load reduction
  • Reduce Cross Subsidy, thus

reduction of regulatory

  • verhang
  • T&D Loss reduction by reduction

load on network and pf improvement

  • Reduce power shortages and

power cuts.

  • Reduction of harmonics in

system, enhancing life of electrical assets

  • Improve the reliability and

quality of power supply

  • Capital deferment by optimizing

load

ESCO Service

Key Milestone Achieved :

  • Empanelled by BEE as Grade 1 ESCO Rating
  • Re-Empanelled six ESCO agencies for the Year 17-18
  • Discovery of competitive energy audit price (range of Rs. 4000/ to Rs. 50,000/) as per load

and customer segmentation wise

  • Collaborative partnership with ESCO project implementing agencies and technology solution

providers (like Honeywell, Katyani, Smart Joules)

Particulars FY 17 (Actual ) FY 18 (Actual) Cumulative Energy Audit conducted (MW) 19 MW 52.5 MW 71.5 ESCO Implementation (MW) 2 MW 6.58 MW 8.58 Objective:- To identify potential energy saving through audit and get benefit from guaranteed energy saving solutions & allied activities through implementation of energy performance improvement projects KPI UoM FY 18 FY 19 FY 20 FY 21 FY 22 Total (5 Yrs) Energy Audit Services MW 50 70 100 150 200 570 ESCO Implementation MW 20 30 40 50 50 190

USP:

  • Investment Grade Energy Audit
  • Partnership with OEM and Technology solution providers
  • Performance guarantee from ESCO agency as per baseline
  • Financing Model

Normal Electrical Network Distribution loss in industry

5%

 Overall energy efficiency of Industry = 50% = 0.83 (17% T&D Loss) x 0.95 (95% Transformer efficiency) x 0.9 (90% motor efficiency) x 0.7 (30% loss in mechanical system like coupling/driver train/pump/valve)  Capacitor Capacity kVAr requirement = kW[tanФ1 - tan Ф2] = kW[tan{cos-1 (cosФ1)} – tan{cos-1 (cosФ2)}]  Reactive kVAr produced in case of lower voltage will be ratio of V1

2 / V2 2 (where V1 = actual voltage & V2 = rated

voltage)  Capacitor consumes 0.2 to 6.0 Watt per kVAr  Reduction of Distribution Loss % in kWh due to PF improvement from pf1 to pf2 = [1 – (pf1 / pf2)2] x 100%
