Overview of India’s Agriculture Sector

•  India’s agriculture sector consumes 22% of total electricity, up from 10% during the 1970’s •  The agricultural tariff has not grown while average cost of supply of utilities is increasing at a fast pace •  Free & flat HP based tariff plan for agriculture has been one of the factors contributing to inefficiencies and thereby high AT&C losses of the State Utilities

Opportunity / PotenDal in Ag DSM

• DSM in Agriculture provides immense opportunity in  Reducing the overall power consumption  Improving efficiencies of ground water extraction  Reducing the subsidy burden of the states without sacrificing the service obligation to the sector

• Most of the pilot projects as well as other studies project potential of 45-‐50% by mere replacement of inefficient pumps • Overall electricity savings (from 20 million pumps) is estimated at 62.1 billion units annually

ObjecDves of the Scheme  To create appropriate framework for market based interventions in agricultural pumping sector through Public Private Partnership (PPP) mode   Intended Outcomes of Programme

  Shelf of bankable DPRs (one in each State) to stimulate the market   Business model through ESCO mode   Baseline development, conducive regulatory regime and security

mechanism   Awareness and outreach to the local farmers and utility employees   Risk Mitigation Measures to encourage PPP   CDM benefits for the scheme

Steps Involved Selection of States

  To rank states for implementation of Ag-‐DSM based on Framework developed

  Attributes to rank the states

  Connected load, percentage consumption by agricultural sector, status of feeder separation, AT&C Losses, Power sector performance rating by PFC

Selection of Feeders for DPR preparation

  To identify eligible feeders for DPR preparation

  Criteria for feeder selection

  No of connected pump sets, HVDS implementation, Dependability on ground water extraction, measurable baseline 12

Steps Involved Engagement of Consultants for DPR preparation

  DPR to be prepared to estimate energy saving potential along with clear baseline

Organization of workshops and Seminars

  Awareness generation and capacity building for utility employees and farmers

Develop a model for Project Implementation

  Identify risk mitigation measures and ring fencing of risks in Ag DSM projects

Risks in Ag DSM Project •  Risks factors outside the ESCO’s control

  Farmer behaviour   Amount of land under irrigation   Cropping patterns   Water table declines   Weather and rainfall

•  These factors cause energy loads to vary, even if the technical performance of the ESCO’s installed systems perform as specified •  Variation in power quality affect pump performance, useful life and maintenance and replacement costs •  ESCOs and their lenders may not be able to accept full exposure to such uncontrollable risks

Deemed Savings Approach •  From the point of view of ESCO and its lender, a stipulated savings protocol (Deemed Savings Approach) may be appropriate

•  Demonstration of performance (measure input power) of a sample of pump sets before and after the project in order to estimate savings for each category and size of pump set

•  This information would then be used to stipulate savings for the entire project area based on fixed hours of operation of pump sets (around 1600)

•  Periodic demonstration of pump set efficiencies during the course of the contract period

•  Even if Deemed savings approach is used to determine payments to the ESCO, the Discom can implement measured savings approach (Monitoring and Verification) for all the feeders to gather the most accurate savings

Benefits to different Stakeholders

• Issues of Concerns in the labeling Program

•  The market is dominated by Submersible pump set ( 70%), mono block(20%) and balance open well ( 10%)

•  The commonly use ratings are 3-‐125 HP, Head range of 5-‐250 m and Discharge of 60-‐2600 LPM.

•  Star labeled pump set are available in 2-‐25 HP and head of 29-‐317 m.

•  BIS not available for Higher capacity of Pump sets. •  Non-‐ availabity of the standard may hamper the Agri-‐DSM Program.

•  Proposal to develop the labeling program for Pumpsets for higher ratings.

•  Request for labeling of Pump sets in all ratings and all discharge.
