    3. Scope of Work

    3.1. In order to enable PDD to comply to the directives of JKSERC under the Tariff Order 2007-08 and Tariff Order 2008-09 and to enable it to know realistic technical and commercial losses at various voltage levels and to chalk out a comprehensive strategy for reduction of these losses to acceptable at primary & secondary distribution levels , PDD has decided to engage a consultant to assist it in conducting detailed loss study which shall include following: (a) Estimation of realistic T&D Losses

    (b) Segregation of T&D Losses into Transmission and Distribution Losses (c) Segregation of T&D losses into Technical and Commercial Losses (d) Sales in MUs to various consumer categories

    (e) Specify Loss reduction trajectory

    (f) Develop action plan for loss reduction

    (g) Any other activity/ies not covered above but considered necessary for

    conducting loss study of a Transmission and Distribution Utility

    (h) From the measured data, reliability indices like SAFI and SAIDI for

    the stations of PDD should be calculated.

    (i) Forecast load M&RE circle wise and from there for entire PDD and

    calculate correlation factor between load growth and losses.

    3.2. The consultant would be expected to act as a T&D loss study expert with in-depth knowledge of Transmission and Distribution Sector.

    Page 4 of 10

    3.3. PDD expects the consultant to execute the entire assignment as per the guidelines

    outlined below; however, PDD is open to alternate plans / guidelines if such

    plans were found to be more efficient. The consultant is supposed to address the

    specified guidelines while submitting the proposal to PDD. Some of the

    guidelines also indicate the specific tasks expected to be undertaken, during the

    engagement, for the benefit of the consultant and the consultant is supposed to

    submit a work plan on the basis of such tasks. However, it should be noted that

    the Consultant is expected to perform all such tasks required for the successful

    implementation of the proposed system and not restrict the scope to those

    mentioned herein.

    3.4. The consultant shall also be responsible for training to be provided to the relevant

    staff of PDD. The various phases along with the specific sub-tasks the consultant

    is expected to perform are outlined below.

    3.5. Brief Methodology

    Step 1: Selection of sample size

    The transmission system at 66kV and above would be fully represented for estimating the Transmission losses. However the sample size for the distribution loss study should be atleast four feeders per M&RE circle in the 66 KV-33KV level, eight feeders per M&RE circle in the 11 KV-6.6.KV level and 50% DTRs on the sampled 11 KV -6.6 KV feeders. Feeders should be selected such that minimum 2% consumers in the respective M&RE circle are covered. Similarly, 50% DTRs should be selected such that all types of DTRs are covered.

    Step 2: Total energy loss estimation

    All the energy input/output at each voltage level shall be measured during a specified period. Similarly the aggregate of all the direct consumption at that voltage level shall also be taken into account corresponding to the specified period. The difference between the input and output readings/aggregated sales at each voltage level gives the net energy lost at that voltage level during the period of study. These percentage energy losses for each voltage level and for the specified period shall be extrapolated to compute the annual energy loss at that voltage level for the system. In J&K there is lot of seasonal variation in energy consumption and as such the measurement of input/output shall have to be carried out over a period of 12 months in order to cover all the seasons of the year and to have fairly correct and acceptable data.

Step 3: Technical loss estimation

    The technical energy losses of the sample network shall be estimated by simulating the system on the computer corresponding to average peak load condition. The peak power losses for each identified sample network shall be assessed on the basis of computer load flow studies. The load factor & loss load factor (LLF) will be worked out from daily load curves. The peak power loss will be then, converted in to energy loss by applying the loss load factor & the time period of study.

Step4: Commercial loss computation

    The difference of the total energy loss as obtained from energy audit and the technical energy loss computed from load flow study gives the commercial energy loss.

3.6 Experience sharing

    PDD understands that similar studies have been conducted in various other

    states of India, for a similar purpose. To the extent possible, the consultant

    would conduct the study considering the same practices so as to ensure

    precision in estimation and planning.

    3.7 Training Needs Analysis (TNA)

    The consultant will keep PDD informed about the activities of studies and

    their progress. Consultant PDD & representative of commission will be

    monitoring progress quarter wise. A third party examiner / monitor from

    CEA, New Delhi will associate the studies. The consultant will outline the

    training requirements to ensure successful implementation and will, at an

    early stage of the engagement, assist PDD in the identification of the

    necessary personnel, and ensure their involvement throughout the process

    of conducting the study. The consultant will ensure to impart adequate

    training to the staff of PDD, especially those who will be directly involved

    during the implementation phase, so as to ensure their common

    understanding of the T&D loss study and loss reduction techniques. 3.8 Documentation

    At least 10 copies of each report shall be provided by the consultant for

    review and approval of PDD. The consultant shall be responsible to

    incorporate comments of PDD and furnish at least 10 copies of revised

    report, within the time frame agreed upon. The consultant may have to

    issue more than one revision of the report so as to prepare it fully up to the

    satisfaction of the PDD/JKSERC.
